Fixa is the most powerful autonomous AI agent on the web, operating inside a full cloud dev environment to build real software. Powered by frontier models, it autonomously browses the web to read live documentation and dynamically installs whatever dependencies your app needs. Fixa writes production-ready backends and features one-click integrations for Stripe, Supabase, Clerk, and Vercel. With our universal MCP connector, you can link any MCP server to integrate deeply with your workflows.
Hey Product Hunt!
I am Etai, a 16-year-old solo developer, and I spent the last few months building Fixa.
I have been testing all the new AI coding tools lately, and while UI generators are great for scaffolding, they hit a hard wall. You cannot build real software without a real environment. I wanted to build something closer to Claude Code, but entirely web-native and capable of building anything.
So, I built Fixa. It is essentially a full autonomous software engineer with its own cloud dev environment.
Because it operates in a full cloud sandbox powered by frontier models, it is not restricted by what I pre-programmed. Here is what it can actually do:
- Autonomous Research: It has a built-in browser. If you ask it to use an API it does not know, it will search the web, read the live documentation, and implement it.
- Build (almost) Anything: It has raw access to its cloud environment to dynamically install whatever languages, frameworks, or dependencies it needs.
- Universal MCP Connector: You can connect any MCP server to let the agent run complex data analytics or interact directly with your existing workflows.
- Production Backends: It writes real, production-ready backend code, wires up databases, and gives you a live preview.
- One-Click Everything: It has native one-click integrations for Stripe, Supabase, Clerk, OpenAI, Google AI, and Anthropic and deploys your full-stack app straight to Vercel in one click.
Building a cloud-native agentic loop that can browse the web, read docs, and write error-free production code was the hardest thing I have ever built. Since it is just me working on this, I would love for the Product Hunt community to push it to its limits.
Ask it to build something complex, let it research the docs, and let me know what you think of the results! I will be hanging out in the comments all day to answer any technical questions.
Thank you,
Etai
The universal MCP connector is interesting but vague. Can you connect to an MCP server that requires OAuth or API key auth, or does it only work with publicly accessible servers right now?
Congrats on the launch Etai! The one-click integrations for Stripe and Supabase are a smart move - that's where vibe coding tools usually break down. You get the UI built in minutes and then spend hours wiring up auth and payments manually. Curious about the MCP connector - can it work with internal APIs too, or is it limited to public MCP servers? We have a bunch of custom integrations in our product and I'm always wondering how far these autonomous agents can go before they need a human to step in and handle the edge cases.
Dude you're 16 and built this?? That's honestly impressive. The universal MCP connector is what really caught my eye — being able to plug any MCP server into an autonomous agent opens up so many workflows. I've been playing with MCP setups for browser automation and database access, and having that baked into a cloud agent is next level. How are you handling auth/security when the agent connects to external MCP servers though? That seems like the trickiest part.
Moving the coding agent to the cloud is a smart play since running large context loops locally always sets my laptop fan on fire. I am really curious how Fixa manages secure access to existing private repos to understand an established codebase. Letting this loose on a backlog of minor UI bug tickets would be a perfect way to test its actual reasoning limits.

Congrats on the launch! This is genuinely impressive. Quick question - when Fixa autonomously installs dependencies and writes backend code, how do you handle security validation? Like, are there guardrails to prevent it from installing malicious packages or introducing vulnerabilities, or does it require human review before deployment?
