Formbricks

Formbricks is the open-source survey platform that goes where Typeform and SurveyMonkey can't — inside your app. In-product micro-surveys, triggered by user behavior, targeting specific segments. It's Qualtrics for indie hackers who want to own their data.

If you're building a SaaS and want to collect user feedback without sending people to external survey links, Formbricks nails the use case. SurveyJS gives you embeddable form libraries with more customization but less out-of-the-box UX. LimeSurvey is the veteran for academic and research surveys. Typebot does conversational forms. Commercially, Typeform and Qualtrics are the polished options you'd be replacing.

The in-app targeting is the killer feature. Show a survey after a user completes onboarding, hits a paywall, or cancels — right when the feedback is most valuable. Self-hosted means no per-response pricing.

The catch: the license is AGPL, so if you modify Formbricks and offer it as a service, you must open-source your changes. The platform is still maturing — expect rougher edges than Typeform. And the self-hosted setup requires PostgreSQL, which is fine for teams comfortable with infrastructure but adds overhead for non-technical founders.
