Your keys, your control
Most AI website builders bundle the AI cost and mark it up behind a subscription you can't escape. OpenThorn is different. You bring your own AI keys, pay providers directly, and keep every line of code. Build anything from a landing page to a full-stack app with a database and user auth — no vendor lock-in, no recurring tax.
Bring your own keys
Hook up OpenAI, Anthropic, Gemini - whatever you use. OpenThorn uses your keys only for requests you make.
Zero platform tax
No subscription, no per-request markup. You pay providers directly and keep what you save.
Your code, your repo
Export everything to GitHub, deploy to your own Vercel account. There is no OpenThorn lock-in.
Real code, real time
OpenThorn writes production-grade code - not a drag-and-drop approximation. Watch every file appear.
Deploy in one click
From prompt to production in under a minute. Push live when you're ready, not when a plan allows.
Full-stack, free
Connect your Supabase project and the agent adds a real database and user auth — Supabase free tier included.
Turn the next rough prompt into a working app.
Skip the platform tax and keep momentum: bring your model keys, generate real code — frontend or full-stack — and ship from your own repo.
