Safe to leave running

A Q works alone, asks before anything new and never merges for you.

  • No keys in the sandbox
  • Approvals on your phone
  • Nothing goes through us

Locked sandbox

The Q works with no keys inside. They stay in your Cloudflare account.

Answer from your phone

Approve, say not now or open the pull request from Telegram.

Several Qs at once

One per task, each in its own sandbox.

You merge

Your own GitHub bot opens the pull request. Merging stays with you.

No Quarn servers

Every request goes to your domain, GitHub or your AI provider. None go to us.

Open source, MIT

Fork it and make it yours. It's your code too.

Questions

What does it cost?

Quarn is free and MIT. You pay Cloudflare, $5 a month on Workers Paid plus usage, and your AI provider.

Where does my code live?

In your Cloudflare account and your GitHub. Nothing goes through Quarn servers, because there aren't any.

Which models can I use?

Claude and ChatGPT with your subscription or an API key, OpenCode Go with your subscription, or any model on OpenRouter.

Can a Q merge or deploy?

No. It opens a pull request under your own GitHub bot, and you decide what gets merged.

What comes after Agents?

Quarn Review, a second opinion on every pull request, and Quarn Notebook, shared memory for your Qs. Both later, on the same account.
