10 Best Open Source Alternatives to Typeform

10 open source alternatives100% OSI-approved licensesUpdated June 2026

Typeform is the polished end of form and survey building, known for clean one-question-at-a-time "conversational" forms with thoughtful design, smooth logic, and a respondent experience that feels less like a chore. Two things send people looking elsewhere. The first is metering - lower tiers cap how many responses you can collect, so a form that takes off can simply stop accepting answers until you upgrade. The second is custody: your respondents' replies, often personal, sit on Typeform's servers rather than yours. The self-hosted open form builders below remove both limits at once. You get unlimited responses with no per-tier ceiling, conditional logic and forms that still look good, and every submission landing on infrastructure you run and control.
