About Formsubmit

FormSubmit is a form backend aimed at static websites and the AI coding tools that build them. One CLI, installed from npm, logs in through a browser device flow, creates a form and returns HTML to paste, then lists submissions as JSON. Every read command supports JSON output with stable shapes and exit codes, so agents in Claude Code, Cursor, Bolt, v0 and Replit can ship a form backend with a single tool call.

The same endpoint is available from a dashboard for people who prefer a visual interface. The product also publishes discovery files so vibe-coding tools can find it, and an agent recipe that checks authentication and credit balance before creating a form. There is no SDK to learn and no server to host. Pricing is credit based: 100 submissions cost $10, spam does not use a credit and credits never expire. The site has pages for developers and teams, docs and a blog.
