AI coding chat.
Your key. Your browser.
Frosone Web is a free chat for any OpenAI-compatible model. Streaming answers, history in your browser, no account. The full local agent with files, terminal and browser ships in the desktop and CLI builds.
Frosone Web, running in a browser. The desktop agent is a separate build.
Your code stays here
Local mode talks only to 127.0.0.1. No telemetry, no remote pixel, no upload.
No credits to watch
The local model has no token cap. Run it all day. Your GPU is the limit, not a billing meter.
Ads pay for cloud
Sponsors fund the cloud quota. Ads are labeled, local-only for stats, and removable in Settings.
What the full agent does
The web beta is chat-only. These are the agent features shipping with the desktop and CLI builds.
Multi-step tool loop
Reads, edits, searches and runs commands. Up to 12 iterations per turn, with streaming.
Parallel workspaces
Each thread can have its own folder. Two agents do not fight over the same files.
Browser control
Playwright drives your real Chrome or Edge, with screenshots back in chat.
Review before apply
Line diff, word diff, checkpoints and one-click undo.
18+ languages
Tree-sitter symbols for navigation and a workspace-wide search.
Memory
MEMORY.md keeps project facts across sessions.
Build an app, not a snippet
Scaffold, write, run, verify. The agent checks the page in a real browser before saying it is done.
1. Scaffold
frosone create shop --template fullstack
2. Build
frosone --workspace shop "add a cart"
3. Run
The agent starts the server, opens the page and fixes what breaks.

FAQ
Is it really free?
The web app is free. You pay your model provider directly with your own key. There is no Frosone subscription and no account.
Does it work offline?
The web app needs the provider you configure. The desktop build runs a local model and works offline.
Is Frosone a Freebuff clone?
No. Frosone is an independent MIT project. It borrows the ad-funded idea, not the code or the brand.
Where is my code sent?
Only to the base URL you configure. Frosone has no server in the middle in the web beta.
Do you see my key?
No. The key stays in your browser localStorage and is sent only to your provider.
Start in the browser
No account. Bring an OpenAI-compatible endpoint and a key.
1. Open the app
frosone.com/app — it runs entirely in your browser.
2. Add a provider
Base URL, model, key. DeepSeek, OpenAI, Groq, OpenRouter, Ollama or LM Studio.
3. Chat
Streaming answers, history in localStorage, key never sent to us.
The desktop agent and CLI are separate builds. They are not required to use the web app.
