Info
OneSignal is the strongest all-rounder, with unlimited free mobile push sends and the most capable MCP server in the category. Firebase Cloud Messaging is free at any volume but is delivery infrastructure, not an engagement platform. PushEngage is the cheapest serious web push option, and Braze has the deepest journey orchestration if you can accept quote-only pricing. All seven were compared on published pricing, what meters the bill, MCP status, and channel coverage.
OneSignal is the best overall push notification software for most teams. Firebase Cloud Messaging is the better answer if you have engineers willing to build targeting and scheduling yourself and would rather not pay for tooling. PushEngage, at $8 a month for up to 50,000 subscribers, is the best push notification software for small business ecommerce sites installing straight through a WordPress or Shopify plugin.
Last updated: August 30, 2026. PickMySoft is reader-supported and independently researched. Every price, quota, and MCP claim below came from vendor documentation on that date, never from a competitor's comparison page.
Why You Need Push Notification Software
- Push is the only channel you own outright. Email lands in a promotions tab and social reach is rented. A notification permission is a direct line.
- Send timing beats send volume. Optimized delivery windows move open rates more than frequency does, and every platform here now automates it.
- Targeting is the difference between engagement and uninstalls. Broadcasting to everyone trains users to disable notifications permanently.
- Cross-channel journeys need one profile. Push, email, and in-app messages that contradict each other are worse than any single channel alone.
- Agents can now query campaign performance. Six of the seven platforms below ship official MCP servers, so results can be pulled without opening a dashboard.
- Free push notification software is genuinely viable now. Two options here send at real volume at zero cost, so the case for paying is orchestration and analytics rather than delivery.
How We Evaluated
Each platform was scored on pricing transparency, what actually meters the bill, AI and MCP maturity, and channel and SDK breadth. We weighted the billing meter heavily, because push notification cost is quoted in at least four different units across these vendors, and the cheapest headline rate frequently produces the largest invoice. We also kept mobile-first platforms and web push notification software in the same comparison, since most buyers evaluate them against each other even though they meter differently. Facts came from vendor documentation only. Full criteria live in our methodology.
1. OneSignal
OneSignal's free tier does something no competitor matches: unlimited mobile push sends, with no volume cap at all. You can run a real push program at meaningful scale before paying anything. Its MCP server is also the most capable here, with 34 tools across nine categories and browser-based OAuth so there is no API key to store or rotate.
Pricing: Free at $0 with unlimited mobile push sends, a 10,000 web push subscriber cap per send, 10,000 monthly email sends, one journey, six segments. Growth from a $19 monthly base fee plus usage: mobile push $0.012 per monthly active user, web push $0.004 per subscriber, email 20,000 free then $1.50 per 1,000. Professional and Enterprise are custom-quoted on annual contracts. USD.
Top Features
- Multi-channel journey builder with branching automation
- Audience segmentation with custom data tags
- Mobile and web push notification delivery at scale
- In-app messaging included with mobile push
- AI-assisted campaign drafting and optimization
- Delivery analytics, A/B testing, and churn detection
Pros
- Unlimited mobile push sends on the free tier
- 34-tool MCP server with OAuth rather than API keys
- Widest SDK coverage including Huawei and Amazon Fire OS
Cons
- SMS and RCS require the custom-priced Professional tier
- Growth caps at 3 journeys, 10 segments, 10 data tags
AI/MCP Integration: Official OneSignal-operated remote server at api.onesignal.com with browser-based OAuth. 34 tools spanning messaging, users, templates, segments, exports, and analytics. Listed in the Claude connectors directory, Cursor Marketplace, and the ChatGPT plugins marketplace. The send_message tool is flagged high-impact so clients can prompt for confirmation.
API Integration: Yes. REST API covering push, email, SMS, users, subscriptions, segments, journeys, data export, and app config, with OpenAPI specs published on GitHub.
Cloud Based: Yes. No self-hosted or on-premise deployment documented.
Platforms: Native iOS, Android, Amazon Fire OS, Huawei, and Web. Cross-platform React Native, Expo, Flutter, Unity, .NET MAUI, Cordova, and Capacitor. Server clients for Go, Python, and .NET.
Channels: Mobile push, web push, email, SMS and RCS, in-app messaging.
Best For: Teams that want a real push program running this week without a procurement cycle or a minimum commitment.
Editor score: 4.6/5. Unlimited free mobile push plus the best MCP implementation in the category is a combination nothing else matches. The published tiers get tight quickly for orchestration-heavy teams, and SMS forces a jump to custom annual pricing, which is why it is not a clean sweep.

2. Braze
Braze is the orchestration ceiling of this group. Canvas Flow is a genuinely deep visual journey builder, and 2026 additions push optimization into the canvas itself: Winning Path and Personalized Paths handle experimentation inline, and Agent steps let a generative agent write per-user copy with Liquid and canvas context available. Push Stories, its scrollable image-carousel format, remains distinctive.
Pricing: Custom-quoted with no dollar figures published. Four editions in 2026: Braze Go, Select, Pro, and Enterprise. The billing model is disclosed even though prices are not: usage scales on monthly active users plus flexible Action Credits spent across channels and select AI products, rather than per-channel licensing.
Top Features
- Canvas Flow no-code cross-channel journey orchestration
- Push Stories carousel notifications with action buttons
- BrazeAI Agent Console for custom in-Canvas agents
- Predictive Suite churn and event scoring
- Decisioning Studio for one-to-one message decisions
- Real-time behavioral segmentation with Liquid personalization
Pros
- Deepest journey orchestration in this comparison
- Widest channel list including WhatsApp, LINE, and RCS
- SDKs down to Roku, FireOS, and TV platforms
Cons
- No published price at any of the four editions
- Action Credits make cost impossible to model pre-sales
AI/MCP Integration: Official first-party server, OAuth-based and tied to dashboard user permissions and SSO rather than a shared API key. Currently Early Access. The AI umbrella is BrazeAI, covering Agents, Content Optimizer, Decisioning Studio, Intelligence Suite, Predictive Suite, and Operator.
API Integration: Yes. REST API documented across 13 endpoint groups including User Data, Messaging, Catalogs, Export, Cloud Data Ingestion, Subscription Groups, SCIM, and Custom Objects.
Cloud Based: Yes, multi-tenant SaaS on AWS with regional clusters. Database tenancy scales from shared to dedicated servers by customer size. No on-premise option documented.
Platforms: Web, Android, Swift, Flutter, React Native, Cordova, Unity, Roku, FireOS, .NET MAUI, plus TV and OTT.
Channels: Push, Live Notifications, in-app messages, Content Cards, Banners, email, transactional email, SMS, MMS, RCS, WhatsApp, LINE, landing pages, webhooks.
Best For: Enterprise lifecycle teams whose bottleneck is journey complexity rather than send volume.
Editor score: 4.3/5. Nothing here orchestrates better, and putting generative agents inside canvas steps is a real advance rather than a feature label. Zero pricing transparency combined with a consumption meter that scales with send volume means you cannot estimate cost before a sales cycle, at any size.
3. Firebase Cloud Messaging
FCM is not really competing with the platforms above, and that is the point. It is the delivery layer Android push physically runs on, and most commercial vendors hand messages to it anyway. You are paying them for tooling, not reach. Google's own page is unambiguous: there is no cost to using Cloud Messaging.
Pricing: Free, with no send limits and no per-message cost. Included in the no-cost Spark plan and still free on pay-as-you-go Blaze. Limits are technical rather than financial: 600,000 messages per minute per project by default, 240 messages per minute and 5,000 per hour to a single Android device, a 4,096-byte payload cap, and 2,000 topics per app instance.
Top Features
- Cross-platform push to iOS, Android, and web
- Topic messaging with unlimited subscribers per topic
- Notification and data message payloads up to 4KB
- No-code Notifications composer with scheduled delivery
- Google Analytics audience targeting plus A/B testing
- Collapsible messages and battery-efficient throttling
Pros
- Genuinely free at any volume, with no tier to outgrow
- Official MCP server maintained by Google in firebase-tools
- A basic campaign console exists, so it is not API-only
Cons
- No journey builder or cross-channel orchestration
- You own token lifecycle, retries, and reporting yourself
AI/MCP Integration: Official. The Firebase MCP server is maintained by Google in firebase-tools, graduated from experimental to generally available in October 2025, and exposes a messaging_send_message tool for sending to a registration token or topic.
API Integration: Yes. The current endpoint is the FCM HTTP v1 API with OAuth2 short-lived tokens. Worth knowing: the legacy FCM HTTP and XMPP APIs were deprecated on June 20, 2023 and shutdown began July 22, 2024, so any tutorial still using a legacy server key is dead code.
Cloud Based: Yes, Google-hosted only. No self-hosted or on-premise deployment.
Platforms: Apple via APNs, Android, Web, Flutter, C++, Unity, plus Admin SDKs for Node.js, Java, Python, Go, and C#.
Channels: Push only, covering mobile and web. No SMS, email, or in-app channel. Firebase In-App Messaging is a separate product and is still labeled Beta.
Best For: Engineering-led teams sending straightforward broadcasts or topic messages who would rather build targeting than pay for it. Related tooling sits in our app development category.
Editor score: 4.2/5. Free at any volume with an official MCP server is remarkable value, and the Notifications composer means it is not purely infrastructure. The console is thin next to a real engagement platform, and Google's recent Firebase retirements, with Dynamic Links gone and Firebase ML ending June 2027, are worth weighing before betting a roadmap on an adjacent Beta product.
4. PushEngage
PushEngage is the cheapest serious option here and the most ecommerce-native. Cart abandonment with dynamic product tags, browse abandonment, back-in-stock, and price-drop campaigns ship as ready-made recipes that install through a WordPress, WooCommerce, or Shopify plugin. A non-developer can launch revenue-recovery campaigns without touching the API.
Pricing: Free at $0 with 200 subscribers, 30 campaigns a month, one site, one workflow. Business $14 monthly at an introductory rate or $8 billed annually, covering up to 50,000 subscribers with sending volume at 40 times subscriber count. Premium $29 or $15 annually for 100,000 subscribers at 50 times volume, adding A/B testing and timezone sending. Growth $60 or $24 annually for 250,000 subscribers at 75 times volume, adding full ecommerce automation. Enterprise custom. USD.
Top Features
- Smart cart abandonment with dynamic product tags
- Browse abandonment and back-in-stock alerts
- Price drop notification campaigns
- Drip and trigger automation workflows
- A/B testing with timezone-based scheduling
- Audience segmentation with goal tracking
Pros
- Lowest published entry price in this comparison
- Official MCP server run through a simple npx command
- Sixteen CMS and ecommerce platform integrations
Cons
- Ecommerce automation is gated to the $60 Growth tier
- Monthly rates are labeled introductory, so renewals may differ
AI/MCP Integration: Official. The @pushengage/mcp package runs via npx with browser-based OAuth login and a locally stored token, working with Claude Desktop, Claude Code, and Cursor.
API Integration: Yes. REST API with an Api-Key header, plus a JavaScript SDK, server-side SDKs, and webhooks.
Cloud Based: Yes. No on-premise option documented.
Platforms: WordPress, WooCommerce, Shopify, Magento, BigCommerce, Wix, Squarespace, Drupal, OpenCart, PrestaShop and more, plus Zapier, Google Analytics, and HubSpot.
Channels: Not web-push-only. Web push plus native Android and iOS app push through native, React Native, and Flutter SDKs, WhatsApp automation, and a multi-channel chat widget.
Best For: Ecommerce stores on WordPress or Shopify that want revenue-recovery campaigns without engineering time. Compare storefront tooling in our ecommerce software category.
Editor score: 4.1/5. Genuinely inexpensive, genuinely capable, and shipping an official MCP server at this price point is not common. The packaging is the flaw: the ecommerce automation that defines the product is withheld until the $60 tier, so a small store gets subscriber headroom it does not need before the features it does.
5. MoEngage
MoEngage covers eleven channels and ships a first-party hosted MCP server with OAuth and permission inheritance, letting a marketer query campaign performance conversationally. Push Amplification, its delivery-boost mechanism for Android devices where standard delivery is unreliable, is a real differentiator in markets with heavy OEM battery management.
Pricing: Custom-quoted with nothing published. Four offerings exist: Inform, Growth, Enterprise, and Personalize, plus metered add-ons. No currency symbol appeared at all on either pricing page, so this is not a geolocation artifact. Billing runs on Monthly Tracked Users using the formula billable MTU equals the greater of total MTU or events divided by the fair usage policy, typically 50 to 500 events per user per month.
Top Features
- Flows journey orchestration across eleven channels
- Behavioral analytics with real-time audience segmentation
- Push notifications with Push Amplification delivery boost
- Merlin AI agentic assistant for marketers
- Web and app personalization with recommendations
- MoEngage Inform transactional alerts via one API
Pros
- Official hosted MCP server with role-inherited permissions
- Eleven channels including RCS and iOS Live Activities
- Region-pinned data centers across five geographies
Cons
- No published price at any tier
- MTU billing counts anonymous profiles and background events
AI/MCP Integration: Official, first-party and MoEngage-hosted at mcp.moengage.com with OAuth against the account and role-based permission inheritance. Exposes nine read-only tools covering campaign search, stats, delivery, click performance, device analytics, and content. Supported in Claude and ChatGPT.
API Integration: Yes. Thirteen documented endpoint groups covering Data, Business Events, Campaigns, Segments, Analytics, Push, Cards, Inform, Live Activities, and Personalize, using base64 workspace credentials.
Cloud Based: Yes. No on-premise deployment documented. Region-pinned data centers in the US, EU, India, and Indonesia.
Platforms: iOS, Android, Web, React Native, Flutter, and Unity. Mobile, web, and TV platforms all count toward MTU.
Channels: Mobile and web push, email, SMS, in-app, on-site, Content Cards, WhatsApp, RCS, advertising audience sync, and iOS Live Activities.
Best For: Consumer apps in mobile-first markets where Android delivery reliability is a genuine problem.
Editor score: 4.0/5. The MCP server is properly built and Push Amplification solves a real problem most Western-market vendors ignore. The billing meter is the concern worth stating plainly: MTU counts anonymous profiles and background events, and the events-divided-by-fair-usage floor means a low-traffic but event-heavy app can bill well above its apparent active-user count.
6. CleverTap
CleverTap owns its storage layer, which is unusual. TesseractDB is purpose-built for engagement workloads rather than bolted onto a generic warehouse, and CleverTap cites three billion devices and 36 billion data points a day as the reason deep behavioral segmentation stays fast at high event volume. RenderMax, which optimizes push renderability across Android OEMs, is a genuine engineering answer to a real delivery problem.
Pricing: Core, Pro, and Ultimate. Core lists at $85 a month, though the page was showing a discounted $8.50 under a countdown-timer sale banner when we checked, so treat $85 as the standing list price. Pro and Ultimate are both custom-quoted. Metering is by monthly active users, banded per tier: Core up to 5,000, Pro up to 20,000, Ultimate up to 40,000, with higher bands beyond. Data retention is three years on Core and Pro against ten on Ultimate. USD.
Top Features
- Omnichannel campaign orchestration across eight channels
- TesseractDB purpose-built customer engagement database
- Clever.AI predictive, generative, and prescriptive engine
- RenderMax push renderability optimization for Android OEMs
- Behavioral segmentation, cohorts, and funnel analytics
- AI send-time and channel optimization
Pros
- Publishes a real entry price, unlike Braze or Airship
- Purpose-built storage layer keeps segmentation fast
- CTV and OTT SDKs including Tizen, webOS, and Fire TV
Cons
- Community MCP servers only, no first-party option
- AI capabilities are withheld from the Core tier entirely
AI/MCP Integration: Community only. CleverTap's GitHub organization holds 92 repositories, all SDKs, with no MCP server. Community implementations exist as clevertap-mcp on npm and a Pipedream-hosted wrapper.
API Integration: Yes. REST API documented at developer.clevertap.com covering create, read, update, and delete operations, plus server-side libraries.
Cloud Based: Yes, region-hosted. No on-premise deployment documented.
Platforms: iOS, Android, Web, React Native, Flutter, Cordova, Unity, Unreal, KaiOS, plus Apple TV, Android TV, Fire TV, Samsung Tizen, and LG webOS.
Channels: Mobile push, web push, in-app, app inbox, email, SMS, WhatsApp, RCS via Infobip, and on-site messaging.
Best For: Consumer apps with heavy event volume where segmentation performance matters, especially across CTV and OTT surfaces.
Editor score: 3.9/5. The storage layer is a real architectural advantage and RenderMax solves a problem others hand-wave. Two things hold it back: it is the only platform here without a first-party MCP server, and the visible $85 price does not represent a usable AI deployment, since predictions, recommendations, and send-time optimization are all withheld from Core.
7. Airship
Airship's no-code Scenes and Surveys layer builds genuinely native, on-brand in-app screens without custom HTML or JavaScript overlays, so marketers ship onboarding flows and embedded offers without an app release. Its 2026 positioning adds a set of Airship Agents covering scenes, journeys, campaigns, recommendations, accessibility, and brand guidelines.
Pricing: Custom-quoted with nothing published anywhere. The pricing page offers two paths, Airship Essentials described as a self-service platform, and the enterprise Airship Experience Platform. A self-serve starter signup route exists, but no price, free-tier limit, or included volume is published on either the pricing page or the signup page. Both route to a quote form. No free trial is advertised.
Top Features
- Airship Journeys cross-channel orchestration in a visual UI
- No-code native Scenes for app and web screens
- In-dashboard surveys served inside Scenes
- Dynamic experimentation and A/B testing
- Mobile Wallet passes and credential distribution
- Preference Center and real-time customer data streams
Pros
- Official MCP server documented in developer docs
- Mobile Wallet passes, rare among push platforms
- Scenes build native screens without an app release
Cons
- No published price even on the self-service tier
- No free trial advertised on the official site
AI/MCP Integration: Official first-party server, documented as a developer tool connecting Claude Code, Claude Desktop, and Cursor to the platform for querying channel data, testing push flows, and guided SDK migrations.
API Integration: Yes. REST APIs for messaging, audience operations, event streaming, and wallet, documented at airship.com/docs/developer.
Cloud Based: Yes, also listed on Google Cloud Marketplace. No on-premise deployment documented.
Platforms: iOS, Android, Web via a JavaScript SDK, React Native, Flutter, and Cordova. Web push works in Chrome, Firefox, Edge, Opera, and Safari 16 and later.
Channels: Mobile push, web push, in-app experiences, SMS, MMS, RCS, email, Mobile Wallet, and Message Center inbox.
Best For: Mobile-first brands that want marketers shipping in-app experiences without waiting on an app release cycle.
Editor score: 3.7/5. Scenes is a legitimately good idea and the Mobile Wallet channel is something no other vendor here offers. The commercial opacity is the problem: describing a plan as self-service while publishing no rate, no included volume, and no trial makes evaluation impossible for any team without a procurement process.

How to Choose Push Notification Software
- Identify your billing meter before comparing prices. MAU, MTU, subscribers, and send volume produce wildly different invoices for the same app.
- Read MoEngage's MTU definition specifically. Counting anonymous profiles and background events, with an events-divided-by-fair-usage floor, is not how most buyers assume active users are counted.
- Decide whether you need orchestration or delivery. If you only broadcast, FCM is free and everything above it is tooling you may not use.
- Check which channels sit behind a tier jump. OneSignal puts SMS and RCS in custom-priced Professional, and PushEngage puts ecommerce automation in Growth.
- Confirm the MCP server is first-party. Six vendors here publish real servers. CleverTap's options are community-built, whatever a marketplace listing suggests.
- Verify the SDK for your platform exists. CleverTap reaches Tizen and webOS, Braze reaches Roku, and most competitors stop at mobile and web.
- Treat quote-only as a cost in itself. Braze, Airship, and MoEngage all require a sales cycle before you learn a number, including on plans marketed as self-service.
- Shortlist push notification service providers by channel, not by brand. Mobile Wallet, RCS, LINE, and CTV surfaces each narrow the field to two or three vendors immediately.
What This Actually Costs
Take a consumer app with 100,000 monthly active users sending mobile push only. Firebase Cloud Messaging covers it at $0, and you build segmentation and scheduling yourself. OneSignal Growth works out near $1,219 a month: the $19 platform fee plus 100,000 users at $0.012 each. CleverTap Core cannot serve it at all, since it bands at 5,000 monthly active users, so the real answer is the unpriced Pro tier.
Now switch to a web-only publisher with 100,000 push subscribers. PushEngage Premium covers exactly that at $15 a month billed annually, and OneSignal's web push rate of $0.004 per subscriber lands near $419 including the base fee. Same audience size, a roughly 28-fold difference in cost, entirely because one platform meters subscribers and the other meters channel usage.
Braze, Airship, and MoEngage cannot be modeled at either scale, which is itself the finding.
Final Thoughts
The most striking pattern here is MCP adoption. Six of seven vendors now ship official servers, which is the highest rate of any category we have compared this year, and CleverTap is conspicuous as the sole holdout. That says something about where these platforms expect campaign analysis to happen.
The second pattern is less encouraging. Three of seven publish no price at any tier, and Airship markets a plan as self-service while publishing neither a rate nor an included volume. In a category where the billing meter varies this much between vendors, opacity is a real cost.
Choose OneSignal if you want to be sending this week and might never leave the free tier. Choose FCM if you have the engineering appetite to build targeting yourself. Choose PushEngage if you run an ecommerce store on WordPress or Shopify. Choose Braze if journey complexity, not budget, is your constraint.
MoEngage and CleverTap both make sense for consumer apps at scale, particularly in markets where Android delivery is genuinely unreliable. Airship is worth the sales cycle only if native in-app experiences and Mobile Wallet passes are on your roadmap. More options sit in our marketing archive and the digital marketing tools category.
