I'm a 17-year-old dev who built this over the past few months. The core idea: chain API requests visually and pass data between steps using {{variable}} syntax.

Example workflow: GitHub API → extract {{userId}} → fetch repos → filter by stars > 100 → post to Discord. All in a visual canvas.

The interesting technical bits: - Security-hardened proxy that blocks private IPs and cloud metadata endpoints - JSONPath variable extraction with real-time interpolation - Supabase-powered real-time collaboration (see teammates' cursors) - Cron scheduling using pg_cron instead of Vercel cron jobs

Stack: Next.js 14, TypeScript, Supabase, React Flow. 121 tests covering SSRF protection, rate limiting, and variable interpolation.

Would love feedback on the proxy security model and whether the UX makes sense for your workflow, and just suggestions on improvements and features. Would also be really helpful if you guys can give me ways to find investors or a cofounder to help me!
