This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.

Built-in MCP server for Claude and Cursor changes everything.
Creating forms through plain language is super smooth.
Conversational forms convert way better than long pages.
Free tier limits get hit pretty fast.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
A native Model Context Protocol server lets Claude, Cursor, or any MCP-compatible tool create forms, read submissions, and manage everything in natural language — no UI needed.
Show one question at a time to lift completion rates and reduce drop-off, or switch to a classic show-all-at-once layout. 17 field types with conditional show/hide logic.
Paid plans include unlimited forms, fields, and responses, so your 10,000th submission costs no more than your first.
Sync to Google Sheets, trigger automations in Zapier or n8n, fire custom webhooks, and embed via link, iframe, JavaScript, or popup across any site.
Deploy on your own server with one-command Docker setup, full source access, your own database and storage, custom domains, and white-labeling for full data control.
Onform is an intelligent form-building platform designed around two ideas: forms that feel like a conversation, and forms your AI assistant can operate for you. Its headline feature is a built-in MCP (Model Context Protocol) server rather than a bolt-on plugin, meaning Claude, Cursor, or any MCP-compatible client can create, publish, and update forms, export responses, and pull analytics without opening a browser UI at all.
The builder supports conversational one-at-a-time layouts alongside classic all-at-once forms, with 13–17 field types, smart show/hide logic, drag-and-drop editing, and 167 ready-made templates. Responses flow into your existing stack via Google Sheets sync, Zapier, n8n, custom webhooks, and email alerts, and forms can be embedded by link, iframe, JavaScript, or popup.
Pricing is built to avoid per-response fees. The free tier covers up to 3 forms and 100 responses per month with full MCP access. The Unlock plan (~$120/year) removes form and response limits, adds full analytics and Google Sheets sync, while Unleash (~$290/year) adds team collaboration, drop-off funnel analytics, and custom CSS. A Deploy tier provides self-hosting with Docker, source code access, and white-labeling. Onform is a product by Founding.dev, positioned around owning your tools rather than renting SaaS indefinitely.
Spin up and iterate on lead-capture forms directly from an AI assistant, then push new leads straight into Sheets, your CRM, or an automation webhook.
Use conversational one-at-a-time forms to keep respondents engaged while collecting unlimited responses without per-submission pricing.
Collect customer feedback and use funnel and completion-rate analytics to see exactly where respondents abandon a form.
Deploy Onform on your own infrastructure for zero third-party access, custom domains, and privacy compliance by default.
