Best Online Form Builder Software in 2026 | Top Listed

Jotform is the best overall online form builder software for most teams. Tally is the better choice if your budget is zero and you can live with branding on your forms, and Cognito Forms' flat per-organization pricing makes it the best online form builder software for small business teams that would rather not pay per seat as headcount grows.

Last updated: August 29, 2026. PickMySoft is reader-supported and independently researched. Every price, limit, and API detail below came from vendor documentation on that date.

Why You Need Online Form Builder Software

• Submission caps decide your bill, not seat count. Most vendors here meter monthly responses account-wide, so one viral form can force an upgrade for a one-person team.
• Conditional logic replaces three separate forms. Branching, calculations, and answer piping let one form serve applicants, vendors, and staff without duplicating anything.
• Payments belong in the form, not after it. Collecting money at the point of submission removes an invoice step and a follow-up email from every transaction.
• Compliance is a plan tier, not a checkbox. HIPAA, BAAs, and audit logging sit behind specific plans, and picking wrong means rebuilding on a different vendor later.
• AI agents can now query your responses. Four of the seven expose forms and submissions through MCP, so an agent can analyze results without a CSV export.

How We Evaluated

Each product was scored on pricing transparency, the real limits behind the headline price, AI and MCP maturity, and API access. We paid particular attention to what a free tier actually permits, since this category advertises generously and meters tightly. Facts came from vendor documentation only, never review aggregators. Full criteria live in our methodology.

1. Jotform

Jotform's argument is that everything adjacent to a form is included rather than sold separately. Payments across 40-plus gateways, e-signature documents, approval workflows, and a first-party MCP server all ride on one subscription. The form builder itself is conventional drag-and-drop with 10,000-plus templates, which is fine, because the surrounding ecosystem is the reason to buy.

Pricing: Starter free, Bronze $39/month ($34 annually), Silver $49/month ($39 annually), Gold $129/month ($99 annually), Enterprise custom-quoted.

Top Features

• Drag-and-drop no-code form and survey builder
• 10,000+ prebuilt form templates
• Conditional logic and multi-step branching
• Payment collection via 40+ payment gateways
• Approval workflows and e-signature documents
• Offline mobile data collection on iOS and Android

Pros

• Widest surrounding feature set at no extra charge
• Ten official SDKs plus regional API endpoints
• Offline mobile capture, rare in this category

Cons

• Free tier caps at 100 submissions per month
• Upgrades trigger on volume, not team size

AI/MCP Integration: Official first-party server, hosted by Jotform with OAuth per user. Tools cover listing, creating, and editing forms plus reading and creating submissions. Included at no additional charge on existing plans, with higher rate limits on Enterprise.

API Integration: Yes. REST API with API-key auth, regional endpoints including HIPAA and EU hosts, and official SDKs for Android, C#, Go, iOS, Java, Node, PHP, Python, Ruby, and Scala.

Cloud Based: Yes. No self-hosted option. Enterprise offers dedicated instances across 19 data centers in 15 countries.

Platforms: Web, iOS, Android, tablets, embeddable forms, plus the REST API.

Best For: Teams that want forms, payments, signatures, and approvals from one vendor rather than four.

Editor score: 4.6/5. The most complete package here, and the MCP server costs nothing extra. It loses ground on the free tier, where 100 submissions a month is barely past evaluation, and on volume-based pricing that can push a solo user from $39 to $129.

2. Tally

Tally does the thing nobody else in this category does: it declines to meter the axis everyone else meters. The free plan allows unlimited forms and unlimited submissions under a fair-usage guideline, and it includes the REST API and MCP server at zero cost. The editor works like a Notion document, so you type to build rather than dragging fields around.

Pricing: Free $0 with unlimited forms and submissions. Pro $24/month, advertised as two months off with annual billing. Business $74/month.

Top Features

• Notion-style document editor, type to build forms
• Conditional logic with branching and calculated variables
• Payment collection and checkout blocks
• Answer piping, hidden fields, URL parameter prefill
• Native Notion, Sheets, Airtable, Slack sync
• Form visit and drop-off analytics on Pro

Pros

• Free tier is genuinely uncapped on responses
• REST API and MCP server free on every plan
• Payments, e-signatures, and file uploads on free

Cons

• Tally branding on every free form until Pro at $24
• No self-hosted or on-premise deployment

AI/MCP Integration: Official first-party server at api.tally.so, free on all plans. Exposes 20-plus tools covering form creation and editing, submission retrieval, charts, sentiment, and NPS analysis. It deliberately cannot delete forms or submissions. Works with Claude, ChatGPT, Cursor, Windsurf, Zed, Cline, and Continue.

API Integration: Yes, a real REST API distinct from webhooks. Bearer-token auth, 100 requests per minute, versioned by header. Free for all users including the free plan.

Cloud Based: Yes. No self-hosted option.

Platforms: Browser only. Forms render responsively and can be embedded or shared by link. No native apps documented.

Best For: Small teams and solo builders who need real submission volume without a bill, and developers who want API access without an upgrade.

Editor score: 4.5/5. The most honest free tier in this comparison by a wide margin, and putting the API and MCP server on it is a genuine outlier decision. Branding removal costing $24 is the only real friction.

3. Typeform

Typeform invented the one-question-at-a-time format and still executes it best. For long forms where abandonment is the actual problem, the conversational flow plus per-question drop-off analytics is a measurable advantage, not a stylistic one. The pricing model is where buyers get hurt.

Pricing: Free $0. Basic $28/month ($25 annually), 100 responses. Plus $56/month ($50 annually), 1,000 responses, 3 users. Business $91/month ($83 annually), 10,000 responses, 5 users. Growth Flow $266/month. Talent $119/month. Enterprise custom.

Top Features

• Conversational one-question-at-a-time form flow
• Conditional logic and branching question paths
• Native video and voice question capture
• Drop-off and conversion analytics per question
• Webhooks plus third-party app integrations
• Custom branding, themes, and custom subdomain

Pros

• Best completion rates in the category for long forms
• Official MCP server covering forms and response analytics
• Unlimited forms and questions on every tier

Cons

• Free tier was cut to 10 responses a month in February 2026
• Hitting the cap closes every form in the account

AI/MCP Integration: Official first-party server at api.typeform.com over streamable HTTP with OAuth 2.0, covering forms, automations, contacts, and response analytics.

API Integration: Yes. Create API, Responses API, Webhooks API, and an Embed SDK for JavaScript and React.

Cloud Based: Yes. No self-hosted or on-premise deployment documented.

Platforms: Web builder and respondent surface, embeddable via the SDK. Mobile apps use webview wrappers rather than native SDKs.

Best For: Marketing and research teams running long forms where completion rate is the metric that matters.

Editor score: 4.2/5. The format advantage is real and the MCP server is well-scoped. The free-tier cut to 10 responses is aggressive enough to make genuine evaluation impossible, and account-wide caps that hard-close every form mid-month are an operational risk worth pricing in.

4. Fillout

Fillout's differentiator is that its database integrations create and update existing records rather than only appending rows. Airtable, Notion, Google Sheets, Excel Online, SmartSuite, Salesforce, HubSpot, Pipedrive, Attio, and Monday are all first-party rather than routed through Zapier. If your form is really a front end for a database, this is the shortlist entry.

Pricing: Free $0 with 1,000 responses a month, unlimited forms, unlimited seats. Starter $15/month annually with 2,000 responses. Pro $40/month with 5,000 responses and branding removal. Business $75/month with unlimited responses. Enterprise custom, priced flat rather than per seat.

Top Features

• Drag-and-drop form, quiz, and survey builder
• Two-way database sync with Airtable, Notion, Sheets
• Conditional logic and intelligent response routing
• Built-in payments, scheduling, and digital signatures
• PDF generation and automated workflow runs
• Login forms letting respondents edit past submissions

Pros

• Unlimited seats on every tier including free
• 1,000 free responses a month, second only to Tally
• Native two-way sync rather than Zapier round-trips

Cons

• Branding removal requires Pro at $40, two tiers up
• Which plan unlocks API access is not documented

AI/MCP Integration: Community only for the form builder. Fillout does publish an official MCP server, but it covers Zite, its separate database product, rather than Fillout Forms. A community server wrapping the public REST API exists.

API Integration: Yes. REST API at api.fillout.com with bearer-token auth, rate-limited to five requests per second per account. The plan gate is not documented as of August 29, 2026.

Cloud Based: Yes. No self-hosting. Enterprise offers residency in the US, EU, UK, Australia, or Canada.

Platforms: Browser only, with four embed modes plus link, custom domain, and QR distribution.

Best For: Teams whose forms feed Airtable or Notion, and anyone who needs many collaborators without per-seat costs. Related tools sit in our data management software category.

Editor score: 4.1/5. Unlimited seats on the free plan is a real differentiator in a per-seat category. The branding gate at $40 and the undocumented API tier are what hold it back.

5. Cognito Forms

Cognito Forms prices per organization rather than per user, which changes the math completely for larger teams. Its other distinguishing feature is a calculation engine that behaves like a real expression language: arithmetic, boolean operators, ternaries, and if-then-else, referencing fields across sections, repeating sections, lookups, and person fields. The same expressions drive computed values, defaults, visibility, and validation.

Pricing: Individual free with 100 entries a month and 1 user. Pro $24/month ($19 annually), 2,000 entries, 2 users. Team $49/month ($39 annually), 10,000 entries, 5 users plus 5 guests. Enterprise $174/month ($129 annually), unlimited entries, 20 users plus 20 guests, HIPAA and BAA.

Top Features

• Calculation engine with formula expressions and conditionals
• Conditional logic driving visibility, validation, routing
• Automatic document generation from entry data
• Payments via Stripe, PayPal, Square, and Cognito Pay
• Repeating sections, tables, save-and-resume forms
• Workflow approvals, e-signatures, audit-log history

Pros

• Per-organization pricing, so 20 users cost one flat rate
• One expression language covers logic, math, and validation
• Official MCP connector listed in the Claude directory

Cons

• HIPAA and a BAA require Enterprise at $174 a month
• MCP connector unavailable on the free tier

AI/MCP Integration: Official first-party server at mcp.cognitoforms.com with OAuth, listed in the Claude connectors directory and the ChatGPT app store. Available on Pro, Team, and Enterprise only.

API Integration: Yes. REST API covering forms, entries, files, and documents with API-key auth over TLS 1.2 or higher.

Cloud Based: Yes, hosted on Microsoft Azure. No self-hosting, which Cognito Forms states explicitly.

Platforms: Browser-based, mobile-responsive public forms, embeddable via JavaScript or iframe, plus REST API, webhooks, and connectors for Zapier, Power Automate, and Make.

Best For: Mid-size teams with complex form logic, especially where headcount would make per-seat pricing painful.

Editor score: 4.0/5. The calculation engine and per-organization pricing are both genuinely differentiated. Putting HIPAA behind a $174 tier, when Jotform offers it lower, is the clearest reason it does not rank higher.

6. Paperform

Paperform treats payments as a first-class primitive rather than an add-on. Stripe, Square, Braintree, PayPal Business, Google Pay, refunds, 3D Secure, and tax calculations are available on the free plan, with subscriptions and coupons from Essentials up. The editor is document-style, so questions sit inside sentences. It turns a form into a working storefront without a separate commerce tool.

Pricing: All figures in USD despite Paperform being Australian. Free $0 with 30 submissions a month. Essentials $24/month annually ($29 monthly) with 1,200 submissions a year. Pro $49/month with 12,000 a year and API access. Business $99/month with 120,000 a year and SSO. Enterprise quote-only.

Top Features

• Doc-style editor with questions inside sentences
• Payments via Stripe, Square, Braintree, PayPal, Google Pay
• Products, subscriptions, coupons, and tax calculations
• Conditional logic, scoring, and calculation fields
• Google Calendar-synced appointment and booking fields
• 2,000+ integrations plus webhooks and REST API

Pros

• Payment collection available even on the free plan
• Booking and appointment fields built in, not bolted on
• Regional data residency on Enterprise

Cons

• Essentials caps at roughly 100 submissions a month
• API access requires Pro at $49, locked below that

AI/MCP Integration: Community and third-party only. Paperform's own integrations directory lists a Zapier-mediated MCP client route rather than a first-party server. No official Paperform MCP server is documented as of August 29, 2026.

API Integration: Yes. REST API at api.paperform.co with bearer-token auth and regional variants for Enterprise. The Standard API requires Pro or above, and the Business API requires Business or above. Free and Essentials have no API access.

Cloud Based: Yes. No on-premise. Enterprise offers Australian and European data residency.

Platforms: Browser for both builder and forms. Distribution via hosted link, embed, oEmbed, QR, and an official WordPress plugin. No native apps.

Best For: Small businesses selling something through a form, where checkout and booking matter more than raw submission volume.

Editor score: 3.9/5. Payments on the free plan is a genuinely generous decision. The submission allowances undercut it: the tier most small businesses buy caps payment submissions at 240 a year, throttling the feature that defines the product.

7. Formstack Forms

Formstack is the enterprise and regulated-industry entry. HIPAA-configured accounts with a standard or custom BAA, AES-256 encryption at rest, audit logging, field and folder-level permissions, and a native Salesforce AppExchange application add up to a compliance posture that self-serve tools do not attempt. It is also the only product here with no free tier.

Pricing: Forms $83/month annually or $99 monthly, covering 1 builder user, 25 forms, 1,000 submissions per form. Suite $250/month annually or $299 monthly, adding Documents and Sign. Salesforce Solutions and Enterprise are both custom-quoted. No free plan, 14-day trial with no card.

Top Features

• Drag-and-drop form builder with conditional logic
• AI-assisted form creation and field generation
• Native Salesforce forms and document generation
• PCI-compliant payment collection and file uploads
• Save-and-resume, field prefill, input validation
• Data routing, webhooks, third-party integrations

Pros

• Strongest compliance posture in this comparison
• Native Salesforce build rather than an integration
• Two live API versions including an OpenAPI-compliant one

Cons

• No free tier and the highest entry price at $83
• No official MCP server documented

AI/MCP Integration: None official. Third-party servers exist through Zapier MCP and Pipedream MCP, per those vendors' own listings. No MCP server appears on formstack.com or developers.formstack.com as of August 29, 2026.

API Integration: Yes. REST and JSON with two live versions: V2 and V2025, the latter OpenAPI-compliant with personal access token auth and daily per-token rate limiting.

Cloud Based: Yes. No self-hosted or on-premise deployment documented.

Platforms: Browser-based web app, embeddable and hosted forms, native Salesforce application. The Formstack Go offline mobile app is end-of-life.

Best For: Regulated organizations and Salesforce-native teams where compliance evidence matters more than price.

Editor score: 3.7/5. It earns its position on compliance depth and the Salesforce build. The score reflects price and packaging: $83 a month for a single builder user with no free tier is the steepest entry here, and HIPAA is not self-serve at any published price.

Comparison Table

How to Choose Online Form Builder Software

• Model your real monthly volume first. Nearly every vendor meters responses account-wide, so your submission forecast picks your tier before any feature does.
• Check what the free tier actually permits. Typeform allows 10 responses a month, Jotform 100, Paperform 30, Fillout 1,000, and Tally effectively unlimited. These are not comparable offers.
• Confirm compliance is on a tier you will buy. HIPAA sits on Cognito Forms Enterprise at $174 and behind sales at Formstack. Getting this wrong means migrating later.
• Find out when branding disappears. Tally removes it at $24, Fillout not until $40. On a public-facing form that is a brand decision, not a feature.
• Verify API access is included, not gated. Tally ships its API on the free plan. Paperform locks it until $49 and Fillout does not publish the threshold.
• Ask whether MCP is first-party. Jotform, Typeform, Tally, and Cognito Forms publish real servers. Fillout's official server covers a different product, and Formstack and Paperform rely on third-party routes.
• Count seats only where they cost money. Fillout and Tally do not charge per seat, so team size stops mattering. Everywhere else it compounds.

What This Actually Costs

Take a team collecting 5,000 responses a month with five people building forms. Tally Pro covers it at $24, since responses are not metered. Fillout Pro handles exactly 5,000 at $40. Cognito Forms Team allows 10,000 entries for five users at $49. Jotform Gold reaches 10,000 submissions at $99. Typeform Business is the priciest fit at $91 for 10,000 responses across five users.

Paperform is the awkward one: 5,000 a month is 60,000 a year, which lands on Business at $99 rather than Pro. Formstack starts at $83 but allows 1,000 submissions per form on that tier, so real volume pushes toward Suite at $250.

Final Thoughts

The pattern worth noticing is that response metering, not seats or features, is what actually sets your bill in this category. Two vendors have opted out of it. Tally does not meter responses at all, and Fillout does not charge per seat. Everyone else compounds both.

Buy Jotform if you want one vendor for forms, payments, signatures, and approvals. Buy Tally if you want a serious web form builder software option at zero cost and can tolerate branding until you upgrade. Buy Typeform if abandonment is your measured problem and you have budget for the response caps. Buy Cognito Forms if your logic is genuinely complex or your headcount would make per-seat pricing hurt.

Formstack and Paperform both make sense for narrower reasons: one because your compliance team requires the evidence, the other because you are selling something at the point of submission. More options sit in our productivity tools archive and the business management software category.
