FregatGitHub

The complete IDE in your browser, with your agents inside.

Fregat runs on your machine and opens in any browser. Our own editor and terminal, language servers and git, with Claude Code and Codex on your own logins.

One prompt, three models. Each works in its own git worktree; results arrive with their tests. Shown in the Tokyo Night bundle: its palette, code theme, winding-road wallpaper and glass.

Review agents like pull requests

Every turn is a checkpoint. Undo one hunk and keep the rest, batch line comments into one message, or ask a second model to review the change.

Rosé Pine bundle, sunset-lake wallpaper.

Work keeps going

One server per machine serves every window and browser. Updates wait for running agent turns, check themselves live and roll back if the check fails. Terminals come back with their output.

Terminal reattach after a restart ships on Linux; macOS is in progress.

Sage bundle, fern wallpaper.

Nothing is lost

Undo in the file tree brings back a deleted folder with its open tabs and unsaved edits. The editor's history is a graph you can browse, and it survives closing the file.

Catppuccin bundle, waves wallpaper.

Bring your own agents

Claude Code and Codex run side by side on the logins you already have. Permission rules are saved as real rules in each tool, and every chat shows its usage, limits and cost.

Graphite bundle, layers wallpaper.

Built from our own parts

Each one is a library with its own site and benchmarks, so you can check the numbers on your machine.

Run it on your machine.

$ git clone https://github.com/ShaulLavo/fregat && cd fregat

Linux and macOS. Needs Bun and Git. No account.
