What is braincell.sh?

braincell.sh is an open-source AI agent platform. You describe an app in plain English; the agent designs it, writes the code, runs it in a Vercel microVM sandbox, verifies it with typecheck/lint/build, and ships it to a live *.vercel.app URL.

How is braincell different from Lovable, v0, Bolt, or Emergent?

braincell is open-source, runs every project inside a real Vercel microVM sandbox (not a static preview), captures a snapshot on every assistant turn for one-click rollback, and supports multiple frontier models including Claude Opus 4.7, Sonnet 4.6, Haiku 4.5 and OpenRouter providers.

Which AI models does braincell.sh support?

Anthropic Claude Opus 4.7 (default), Sonnet 4.6, Haiku 4.5, and OpenRouter fallbacks including GPT-5 and others. You can switch models per project.

Where does my deployed app go?

One-click deploys go to your own *.vercel.app subdomain. You can attach a custom domain from the workspace.

Is braincell.sh free?

Yes — every new account gets 10 free credits. Standard ($20/mo) refills 100 credits monthly, Pro ($100/mo) refills 750. Credits are debited by token usage on each agent run.

Pace

I drew a wireframe on a napkin and described it. Forty minutes later I had a real product at a real URL, billing already wired in. My co-founder thought I had hired someone.
