Imagine having a senior developer sitting right next to you — one who never gets tired, never judges your questions, and can write entire apps in seconds.
That's Forge.
You open the browser, describe what you want to build, and Forge's AI reads your files, writes code, and updates your project — all while you watch it happen in real time. No installations. No confusing terminals. Just you and your ideas.
When you're done, Forge runs your app live inside the browser — you can see it working immediately. And with one click, you can push it straight to GitHub.
A beautiful split-screen landing page — showcase on the left, sign-in on the right. Works great on mobile too.
Type what you want to build, or paste a GitHub link to bring in an existing project.
A full code editor on the left. A chat sidebar on the right. Ask Forge anything — it reads your files, makes the changes, and explains what it did.
Switch to Preview mode. Forge installs dependencies and boots your app inside the browser. No terminal. No local server.
Every AI chat is saved per project. Browse and pick up any past conversation right where you left off.
Quickly jump between all your projects with a command palette (Ctrl + K), export your work to a GitHub repo, or manage your plan — all without leaving the app.

Forge runs the AI inside a background job (Inngest), so it never blocks the UI. Your editor stays fast while the AI does the heavy lifting.
