Iโm excited to share Submify โ an open-source, self-hosted Form Backend as a Service (FBaaS).
๐ฅ The problem
If youโve ever built a website, you know forms are deceptively painful:
You either rely on third-party services (and give away your data ๐)
Or you build everything from scratch (auth, storage, spam protection, dashboardsโฆ)
Scaling, file uploads, exports, notifications โ it all adds up fast
For developers who care about control, privacy, and ownership, the current options are limiting.
๐ The solution โ Submify
Submify is a fully self-hosted form backend stack that gives you everything you need out of the box:
โก Simple JSON form submission API
๐ Clean dashboard to manage submissions
๐๏ธ Export to XLSX / PDF
๐ Secure API key-based ingestion
๐ฆ File uploads with S3-compatible storage (MinIO/RustFS)
๐ Optional Telegram notifications
๐งฑ Built with Go (Gin), Next.js, PostgreSQL, and Nginx
All running behind a single entry point, deployable with Docker in minutes.
๐ฏ Why I built this
I wanted a no-middleman solution where:
Your form data stays yours
You can run everything on your own server
And still get a modern dashboard + developer-friendly API
Basically: the power of SaaS, without the SaaS lock-in.
๐จโ๐ป Who is this for?
Indie hackers & SaaS builders
Developers building client projects
Agencies managing multiple websites
Anyone who wants a form backend they fully control
๐ Would love your feedback
This is just the beginning โ Iโm actively improving it.
What features would you want next?
Would you use this in production?
Anything confusing in setup or docs?
Your feedback will directly shape the roadmap ๐
Thanks for checking out Submify โค๏ธ
