Formgrid is an open-source form backend that turns any HTML form into a secure submission endpoint. You point a plain form’s action at it, and it captures the responses, screens spam with a honeypot and rate limiting, emails you each submission, and stores everything in your own database. It self-hosts with Docker and is released under the MIT license.

Our take
Formgrid is the lightweight answer for a static site that just needs a working contact form without surrendering the responses to a hosted service. You keep your own HTML, point the form at your instance, and the submissions land in a database you run, screened for spam on the way in. The MIT license is about as permissive as it gets, so you are free to deploy and modify it as you like. The honest catch is youth: it is led by a single developer and still maturing, and you run and patch the backend yourself. Pick it if you are comfortable self-hosting and want a form endpoint you fully own. If you would rather not run a server, a hosted builder is the easier road.

Frequently asked
- What does Formgrid actually do?
- It gives any HTML form a submission endpoint, so you point your form's action at Formgrid and it captures the responses, blocks spam, then emails you each one. There is no form to build inside a dashboard: you keep your own markup and Formgrid handles the back end.
- Is Formgrid open source?
- Yes, under the MIT license, one of the most permissive there is. You can self-host the whole stack with Docker for unlimited use, so the submissions land in your own database rather than a third party's.
- Is Formgrid mature enough to rely on?
- It is young and led by a single developer, so the bench is thin and the surface area is still growing. For a personal site or a small project where you run the backend yourself it is a clean fit; for mission-critical infrastructure, weigh that maturity first.
