Fixa.dev Launches on Product Hunt — 16-Year-Old Solo Dev Ships Cloud-Native AI Agent That Builds Full-Stack Apps Autonomously

Product Hunt·medium signal

Fixa, built by 16-year-old solo developer Etai, is a cloud-native AI agent that operates inside a full cloud dev environment to build production software from idea to deployment. It has a built-in browser that reads live documentation for unknown APIs, dynamically installs any dependencies needed, and ships one-click integrations for Stripe, Supabase, Clerk, and Vercel. Supports MCP server connections for complex data analytics. Launched on Product Hunt around April 23 — the youngest solo dev shipping a full autonomous coding agent to production.
