@github-actions github-actions released this 02 Nov 10:06

The first public release of Rook, a cross-platform Agentic Development Environment (ADE) for Windows, macOS and Linux.

Rook runs real coding agents (Claude Code and Codex) inside your project folders. It streams their replies with tool activity and approvals, and keeps every chat's history. Each workspace adds tabs for changes, a terminal, files and a browser, plus a Git flow that goes from commit to push to pull request. Agents sign in through their own official tools and keep their own credentials.

Early release. Rook is pre-1.0: expect rough edges and breaking changes between versions. Please report bugs and report security issues privately as described in SECURITY.md.

Installing

These builds are not code-signed yet, so your OS will warn you the first time.

  • Windows: if SmartScreen says "Windows protected your PC", choose More info → Run anyway.
  • macOS: open the .dmg and drag Rook to Applications. If macOS says Rook "is damaged" or "can't be opened", run this once in Terminal, then open Rook again:
    xattr -dr com.apple.quarantine /Applications/Rook.app
  • Linux:
    • AppImage: chmod +x Rook-0.1.0-linux-*.AppImage and run it (needs FUSE 2, e.g. libfuse2 on Ubuntu).
    • Debian/Ubuntu: sudo apt install ./Rook-0.1.0-linux-amd64.deb
    • Fedora/RHEL: sudo dnf install ./Rook-0.1.0-linux-x86_64.rpm

Updates

The Windows installer, the AppImage and the macOS app check this repository for new releases. On macOS, automatic updates need a signed app, so download new versions from the Releases page for now. The portable Windows build and the deb/rpm packages do not update themselves.

Verify your download

SHA256SUMS.txt lists the SHA-256 checksum of every installer. GitHub also shows each file's digest next to it below.

sha256sum --check --ignore-missing SHA256SUMS.txt          # Linux
shasum -a 256 --check --ignore-missing SHA256SUMS.txt      # macOS

On Windows: Get-FileHash .\Rook-0.1.0-win.exe and compare with the list.
