Opnform
OpnForm is a scrappy, open-source AI form builder that punches well above its price point — the free tier is genuinely generous, and the $16/mo Pro plan is nearly impossible to beat on value. The trade-off is a thin social proof footprint and limited design polish compared to Typeform or Tally.
OpnForm delivers a generous free tier with solid form-building capabilities, webhooks, API access, and conditional logic, with active development and integrations, though independent G2/Capterra review data was unavailable to confirm broad user satisfaction.
Recent CVE security patches (v2.6.1) show responsiveness but also indicate active vulnerabilities; no SOC 2 certification found, privacy/training data posture is ambiguous, and the small bootstrapped team raises stability concerns.
No institutional funding discovered, adoption signals are limited to developer community mentions and AppSumo listing with ~10 initial customers, and structured review-platform data (G2/Capterra) was not retrievable for this tool.
Strong infrastructure signals including open-source AGPLv3 codebase, active GitHub commits, Docker self-hosting, versioned MCP server integration, webhooks, and Zapier support; API is available on all plans but OpenAPI spec and full versioning details were not confirmed.
Most form builders make you pay the moment things get interesting — the second you want a webhook, an API call, or conditional branching, the pricing page appears. OpnForm bets against that model entirely, shipping a free tier that includes almost everything and a Pro plan that costs less than two coffees a week. The question is whether the trade-offs in design flexibility and enterprise credibility matter for your use case.
