Info
Agora, LiveKit, Twilio Video, Daily, Vonage Video API, Amazon Chime SDK, and Stream Video were compared on real per-minute pricing, MCP and API maturity, AI voice-agent support, and self-hosting options. All seven let a developer embed live video calling into their own app rather than build WebRTC infrastructure from scratch.
Agora is the best overall video calling API if you need proven, large-scale, low-latency video across 200-plus countries. LiveKit is the better choice if you are building an AI voice or video agent and want the option to self-host. Daily and Agora's roughly 10,000 free monthly minutes also make them the best video calling API for small business apps doing a few hundred calls a month, since usage often stays inside the free tier entirely.
Why You Need a Video Calling API
- Skip the WebRTC plumbing. Building reliable multi-party video from raw WebRTC takes months of edge-case handling that these platforms have already solved. Most teams end up deploying the surrounding backend on a PaaS platform rather than managing that infrastructure themselves too.
- Global low-latency delivery. A video call between two people on different continents needs a routing network most teams cannot build or operate themselves.
- Built-in recording and transcription. Compliance and support teams increasingly need a searchable, timestamped record of every video interaction, not just the live stream.
- Real-time AI voice agents. Several of these platforms now double as the media layer for AI agents that listen, respond, and interrupt naturally in a live call.
- Usage-based cost control. Paying per participant-minute instead of per seat means the bill tracks actual usage instead of headcount.
How We Evaluated
Each product was scored on pricing transparency, real-time network performance, AI/MCP maturity, and deployment flexibility (cloud-only versus self-hostable). Full criteria live in our methodology.
1. Agora
Agora built its own global real-time network specifically to move video and audio with minimal delay, and it shows in how the company talks about scale: broadcasts with hundreds of thousands of viewers, not just one-on-one calls.
Pricing: First 10,000 combined RTC minutes free each month. After that, $0.59 per 1,000 minutes for core video/voice. Recording, transcription, translation, and analytics are billed separately, from $0.99 to $16.99 per 1,000 minutes depending on the feature.
Top Features
- Global low-latency network across 200+ countries
- Up to 4K/60fps video and 192kbps audio
- Interactive live streaming with co-hosting
- Real-time speech-to-text and translation add-ons
- Multi-track simultaneous publishing
- On-premises recording for compliance-sensitive teams
Pros
- Proven at massive broadcast scale
- Broad SDK coverage, including Unity and Unreal
- On-prem recording option most rivals lack
Cons
- Pricing is split across many separately metered add-ons
AI/MCP Integration: None official for the core API. A community-built MCP server exists for project management, and Agora's own Agent Studio can attach external MCP servers.
API Integration: Yes. REST API with public docs.
Cloud Based: Yes. On-premises option available for recording only, not the core real-time network.
Best For: Teams running large interactive broadcasts or livestreams that need proven global scale.
Editor score: 4.6/5. Loses points only for pricing that requires adding up many separate line items to estimate true cost.
2. LiveKit
LiveKit is the odd one out on this list in a good way: it is open source at its core, and the same media server that powers its managed cloud can run entirely on your own infrastructure. That dual model has made it the default choice for teams building real-time AI voice agents, often alongside the same AI code generation tools they use to write the agent logic itself.
Pricing: Free Build tier (5,000 WebRTC minutes, 1,000 agent-session minutes). Ship tier from $50/month (150,000 WebRTC minutes). Scale tier from $500/month (1.5M WebRTC minutes, SOC 2 Type II reports). Enterprise is custom-quoted. Self-hosting the open-source server costs nothing beyond your own infrastructure.
Top Features
- Real-time AI voice/video agents with turn detection
- Telephony and SIP with phone number provisioning
- Full agent session observability
- Pluggable STT/LLM/TTS provider support
- Open-source, self-hostable media server
- 16+ global cloud regions when using LiveKit Cloud
Pros
- No vendor lock-in thanks to open-source self-hosting
- Purpose-built for conversational AI agents, not just human calls
- Generous free Ship tier for early production use
Cons
- Free Build tier caps out fast at only 5 concurrent agent sessions
AI/MCP Integration: LiveKit Agents natively supports connecting out to external MCP servers as a client. There is no official LiveKit-published MCP server for the platform's own API.
API Integration: Yes. REST and SDK APIs with public docs.
Cloud Based: Yes, via LiveKit Cloud. On-premises option: yes, the media server and Agents framework are fully open source.
Best For: Teams building AI voice or video agents who want the option to self-host.
Editor score: 4.6/5. The open-source path plus AI-agent focus makes it the most future-facing option here, docked slightly for a tight free tier.
3. Twilio Video
Twilio Video survived a real scare. In March 2024, Twilio announced it would sunset Programmable Video and pointed customers toward Zoom's Video SDK, then reversed course and recommitted to the product. It is still worth knowing about, since it explains why some competitors now market directly at former Twilio Video customers.
Pricing: $0.004 per participant-minute for video calling, $0.004 per participant-minute for recording, $0.027 per room-minute for transcription. Volume and committed-use discounts are custom-quoted.
Top Features
- Real-time multi-language transcription, HIPAA-eligible
- AI noise cancellation and virtual backgrounds
- Network Bandwidth Profile and Network Quality APIs
- Native interop with Twilio Voice, Messaging, and Flex
- Screen sharing with in-call text chat
- JavaScript, iOS, and Android SDKs
Pros
- Deep integration across Twilio's broader communications suite
- Official MCP server with wide API coverage
- Transparent per-minute pricing
Cons
- The 2024 end-of-life announcement, even reversed, is a real trust hit some buyers still weigh
AI/MCP Integration: Official. Twilio Labs runs the Twilio MCP Server, exposing the full API surface including Video.
API Integration: Yes. Public docs at twilio.com/docs/video.
Cloud Based: Yes. No on-premises option.
Best For: Teams already inside the Twilio ecosystem who want video alongside Voice and Messaging in one bill.
Editor score: 4.2/5. Strong technically; the score reflects real buyer hesitation from the 2024 sunset scare, not a current product gap.
4. Daily
Daily's whole pitch is developer speed: sign up, drop in an SDK, and have a working call in an afternoon. It has also become a common pick for teams prototyping real-time AI voice products, thanks to low-level control over media tracks and codecs.
Pricing: 10,000 free participant-minutes a month, no card required. After that, $0.004 per participant-minute for video/audio, $0.00099 for audio-only, with volume discounts down to $0.0015/minute past 50 million minutes a month.
Top Features
- Custom media tracks with adaptive codecs
- RTMP/HLS ingest and live streaming
- Built-in cloud recording with real-time compositing
- Real-time and post-call transcription
- Adaptive HEVC encoding on iOS
- Global mesh network with roughly 13ms median first-hop latency
Pros
- Fastest path to a working integration
- Transparent, easy-to-model usage pricing
- Deep low-level control for custom media pipelines
Cons
- No official MCP server yet
AI/MCP Integration: None found, official or community.
API Integration: Yes. REST API and client SDKs with public docs.
Cloud Based: Yes. Enterprise customers get VPC-flavored deployments, but there is no true self-hosted or on-premises option.
Best For: Developers who want the fastest, cleanest integration with predictable per-minute pricing.
Editor score: 4.5/5. The developer experience and pricing clarity are genuinely best-in-class; only the missing MCP server holds it back.
5. Vonage Video API
Vonage Video API is the product formerly known as OpenTok, built on the TokBox acquisition. Vonage has leaned hard into positioning it as the landing spot for teams spooked by Twilio's 2024 announcement, publishing a direct migration guide for exactly that audience.
Pricing: Usage-based with no subscription. Reported at roughly $0.0041 per participant-minute up to 25 active publishers, rising to about $0.02275 past 36 publishers, per third-party sources; Vonage's own pricing page returned an error on direct fetch and was not independently re-confirmed. A 75,000-minute free trial is available. Enterprise volume pricing is custom-quoted.
Top Features
- Multi-party WebRTC sessions, peer-to-peer and routed
- Screen sharing and broadcasting via RTMP/HLS
- Experience Composer for custom video layouts
- Cloud recording and archiving, SD through Full HD
- Live captions and real-time transcription
- Client SDKs for web, iOS, Android, Windows, and macOS
Pros
- Marketed and documented specifically as a Twilio Video migration target
- Granular per-participant billing rather than per-host
- Experience Composer gives programmatic control over layouts
Cons
- Per-participant cost rises steeply, roughly 4.5x, once a session passes 25 active publishers
AI/MCP Integration: None specific to Video API. Vonage runs an official general-purpose Documentation MCP server covering all its products' docs, and a separate community Telephony MCP server for voice and SMS, but neither is a dedicated Video API tool-calling server.
API Integration: Yes. Public docs at developer.vonage.com/en/video.
Cloud Based: Yes. No on-premises option.
Best For: Teams migrating off Twilio Video who want a documented, guided path.
Editor score: 4.1/5. Solid and purpose-marketed for a real buyer scenario, docked for unconfirmed official pricing and the publisher-count cost cliff.
6. Stream Video
Stream built its name on chat and activity feeds before adding video, and that scale-first mentality carries over: its video product is built to handle both small one-on-one calls and livestreams with over 100,000 concurrent viewers on the same infrastructure.
Pricing: Free Build tier includes 333,000 participant-minutes a month plus $100 in monthly credit, audio-only quality. Pay-as-you-go from $0.30 per 1,000 participant-minutes for audio, with higher rates for video and HD. Enterprise starts at 1 million participant-minutes, custom-quoted with a 99.999% SLA.
Top Features
- Global edge-network SFUs for low-latency calls
- Adaptive media optimization with dynamic codec switching
- Scales to 100,000+ concurrent participants for livestreams
- Noise cancellation, recording, and multi-language transcription
- Background blur and picture-in-picture
- SOC 2, ISO 27001, and HIPAA compliance with SSO
Pros
- Largest included free tier of any product compared here
- Same infrastructure handles both small calls and mass livestreams
- Strong compliance posture out of the box
Cons
- No self-hosted or on-premises option
AI/MCP Integration: None for Video. An unofficial community MCP server exists for Stream's separate Feeds API, not for Video.
API Integration: Yes. Public docs at getstream.io/video/docs.
Cloud Based: Yes. No on-premises option.
Best For: Apps that need to scale from small group calls to mass livestreams without switching platforms.
Editor score: 4.4/5. The free tier alone makes it worth evaluating; the lack of any self-hosting option is the real ceiling.
7. Amazon Chime SDK
Amazon Chime SDK is AWS's answer to embedded video, and it behaves exactly like the rest of AWS: no free tier, no bundled plans, and a long list of individually metered services that reward teams who already know how to model AWS costs. Teams already running containerized workloads through a container registry on AWS will find the IAM and billing setup familiar.
Pricing: Fully pay-as-you-go with no free tier. $0.0017 per attendee-minute for standard WebRTC media, media capture at $0.0125 per minute, call analytics at $0.023 per minute, and separate rates for PSTN calling, messaging, and voice noise suppression.
Top Features
- Real-time audio/video meetings over WebRTC
- Screen sharing and in-app messaging with moderation
- PSTN and SIP voice calling via Voice Connector
- Media capture and recording to S3
- Live streaming via Live Connector
- ML-based call analytics and Amazon Voice Focus noise suppression
Pros
- Granular per-primitive billing means you only pay for what you use
- Native integration with the rest of AWS, including S3 and Kinesis
- No bundled minimums to commit to upfront
Cons
- No free tier and no bundled pricing, so cost estimation requires summing many separate line items
AI/MCP Integration: None found, official or community.
API Integration: Yes. Public docs at docs.aws.amazon.com/chime-sdk.
Cloud Based: Yes. No on-premises option.
Best For: Teams already running deep on AWS who want video to live in the same billing account and IAM setup.
Editor score: 3.9/5. Technically capable, but the absence of a free tier and any MCP support puts it behind the rest of this list for most new projects.
Comparison Table
| Tool | Best For | Starting Price | Standout Feature | AI-MCP Support | API Integration |
|---|---|---|---|---|---|
| Agora | Large-scale interactive broadcasts | 10K free min/mo, then $0.59/1K min | Global low-latency network | Community only | REST |
| LiveKit | AI voice/video agents, self-hosting | Free, or $0/mo self-hosted | Open-source media server | Client support | REST + SDK |
| Twilio Video | Twilio ecosystem users | $0.004/participant-min | Official MCP server | Official server | REST |
| Daily | Fastest developer integration | 10K free min/mo, then $0.004/min | Low-level media control | None | REST |
| Vonage Video API | Twilio Video migrations | $0.0041/participant-min | Experience Composer layouts | Documentation MCP only | REST |
| Stream Video | Scaling to mass livestreams | 333K free min/mo | 100K+ concurrent viewers | None | REST |
| Amazon Chime SDK | AWS-native teams | Pay-as-you-go, no free tier | Native AWS integration | None | REST |
How to Choose
- Decide whether you need to self-host first. Only LiveKit offers a real open-source path; every other product here is cloud-only.
- Check the billing unit carefully. Participant-minutes, attendee-minutes, and WebRTC minutes are not always priced or measured the same way across vendors.
- If you are building an AI voice agent, start with LiveKit or Daily. Both give low-level access to media tracks that agent frameworks need.
- Confirm what happens past your expected concurrency. Vonage's per-participant cost jumps sharply above 25 publishers; check equivalent thresholds for any platform you shortlist.
- If MCP-based tooling access matters to your workflow, only Twilio ships an official server for its video product today.
- Once a video feature is live, monitor call setup latency and API error rates the same way you would any other production service; see our guide to APM tools if you don't already have that covered.
What This Actually Costs
A team running a coaching app with 500 active users, each averaging two 25-minute one-on-one video sessions a month, generates roughly 50,000 participant-minutes monthly. On Daily or Twilio Video, that lands near $200 a month at list price. On Agora, after the 10,000 free minutes, the remaining 40,000 minutes cost about $24. On Amazon Chime SDK, the same volume runs about $85 in core media costs alone, before adding recording or analytics. Stream Video's free Build tier, at 333,000 included participant-minutes, would cover this entire workload at no cost.
Final Thoughts
Pick Agora if you need a network built for scale from day one and can live with itemized add-on pricing. Pick LiveKit if you are building anything AI-agent-shaped or want the self-hosting option in your back pocket. Pick Daily if you just want the cleanest possible integration with pricing you can predict on a napkin. The rest of this list is not a consolation prize: Stream Video's free tier is the most generous here, and Vonage remains the most directly documented off-ramp if you were ever burned by Twilio's 2024 announcement.
