Formbricks

In-app surveys, website pop-ups, and link surveys, all from one platform you can self-host. The open source version is free. You get unlimited surveys, unlimited responses, targeting by user attributes, no-code survey builder, and integrations with webhooks. Self-host it and you own all your survey data.

Formbricks Cloud has a free tier (25 responses/month) and paid plans: Startup at $49/mo (250 responses), Scale at $149/mo (1,500 responses), Enterprise custom pricing. The response limits are the main gate. Self-hosting is moderate effort. Docker Compose with Postgres and the Formbricks app. The docs walk you through it, but you're maintaining a Node.js app, database, and keeping up with updates.

Solo developers: self-host for free if you want user feedback in your app. The 25 free cloud responses are too few for real use. Small teams: self-host or pay $49/mo, depends on whether you want ops or convenience. Growing teams: the $149/mo Scale tier is reasonable for the analytics and targeting features.

The catch: the response limits on Cloud plans are aggressive. 25 responses/month on free is basically a trial. And self-hosting means you're responsible for reliability; if the survey service goes down, you stop collecting feedback.
