We're excited to announce the open source release of FormFeeder OSS — a production-ready form submission handler that we built in a single weekend using agentic coding. Yes, you read that right. A weekend.
This isn't just another form handler. It's a testament to a new paradigm in software development where human expertise meets AI-powered coding assistants to achieve what previously took weeks or months.
The New Developer Reality
FormFeeder OSS was built using agentic coding — combining human architectural decisions and domain knowledge with AI coding assistants that handle implementation details. The result? A fully-featured, tested, production-ready application built in 48 hours that includes:
- 465+ passing tests
- Complete CI/CD pipeline
- Docker containerization
- Comprehensive documentation
- Enterprise-ready features
This is the future of software development. Not AI replacing developers, but developers achieving 10x productivity by focusing on what matters: architecture, user experience, and business logic.
Why FormFeeder?
Static websites are everywhere. They're fast, secure, and cost-effective. But there's always been one pain point: handling form submissions. Whether you're building a landing page with Astro, a portfolio with Hugo, or a documentation site with Jekyll, you eventually need to collect user input — and that's where things get complicated.
FormFeeder OSS solves this problem elegantly. It's a single, self-hosted service that handles all your form submissions, no matter how many static sites you're running.
Start Now at FormFeeder.io
While FormFeeder OSS is perfect for self-hosting, we also offer a fully managed service at formfeeder.io where you can start using FormFeeder immediately — no setup required.
Free Private Forms
Create secure, private form endpoints in seconds:
- Generous API rate limits for real-world usage
- No credit card required to get started
- Privacy Mode included on all free forms
- Instant setup — get your endpoint in under 30 seconds
Perfect for testing FormFeeder before self-hosting, or for projects where you prefer a managed solution.
Developer-First Design
Whether you use the hosted service or self-host, FormFeeder is built with developers in mind:
No Client Libraries Required
Your forms work with standard HTML. No JavaScript. No dependencies. Just a form that works.
<form action="https://api.formfeeder.io/v1/form/YOUR_FORM_ID" method="POST">
<input type="text" name="name" required>
<input type="email" name="email" required>
<textarea name="message"></textarea>
<button type="submit">Send</button>
</form>Multiple Notification Channels
Route form submissions where they need to go:
- Email via MailJet integration
- Slack webhooks for team notifications
- Custom webhooks for your own integrations
- More connectors coming soon
Privacy Mode: Your Data, Your Rules
One of FormFeeder's standout features is Privacy Mode. When enabled for a form, submissions are processed and forwarded to your configured connectors, but nothing is stored in the database.
This is perfect for:
- GDPR-compliant contact forms
- Healthcare inquiries requiring HIPAA compliance
- Any scenario where data residency matters
Privacy Mode gives you the convenience of a form handler without the liability of storing sensitive data.
Built in a Weekend, Built to Last
The Power of Agentic Coding
Using AI coding assistants, we achieved in one weekend what traditionally takes a small team several sprints:
- Architecture: Human expertise designed the system architecture
- Implementation: AI assistants handled the boilerplate and implementation details
- Testing: Comprehensive test suite with 465+ tests written alongside the code
- Documentation: Complete docs generated in real-time as we built
- DevOps: Full CI/CD pipeline configured from the start
This isn't about cutting corners — it's about focusing human creativity on what matters while leveraging AI for the repetitive parts.
Enterprise-Ready Features
Despite the rapid development, FormFeeder includes everything you need for production:
- PostgreSQL backend for reliable data storage
- Built-in rate limiting to prevent abuse
- CORS configuration for cross-origin submissions
- Automatic retries with exponential backoff
- Health check endpoints for monitoring
- OpenAPI/Swagger documentation
Modern .NET 9 Architecture
We chose .NET 9 and minimal APIs for maximum performance and minimal overhead. The entire application runs in a single container with sub-second startup times.
A New Paradigm for Software Development
FormFeeder OSS represents more than just a useful tool — it's proof that the landscape of software development has fundamentally changed. When developers can:
- Focus on architecture instead of syntax
- Iterate at the speed of thought rather than the speed of typing
- Build with confidence knowing tests are comprehensive
- Ship immediately with production-ready code
...we enter a new era of software creation where the gap between idea and implementation shrinks to hours, not months.
