Native installers for Windows, macOS and Linux, plus the terminal agent from PyPI.
Version 0.42.0, released 2026-08-09
The installers are not signed
There is no code-signing certificate, so the first run is blocked by the operating system. This is expected, and it is the only warning you should have to click through.
- Windows: SmartScreen shows "Windows protected your PC". Choose More info, then Run anyway.
- macOS: Gatekeeper refuses a double-click. Right-click the app and choose Open, then confirm.
- Linux: make the AppImage executable with chmod +x before running it.
The desktop app
No Python needed — the backend is bundled with the app.
The terminal agent
Python 3.11 to 3.13. The lean install is the first line; the second brings everything that is not GPU-bound.
pip install chimera-agentpip install 'chimera-agent[full]'Updates are signed, even though the installer is not
The app updates itself from a Minisign-signed manifest, so an update cannot be swapped for something else in transit. That is a separate mechanism from the installer warning above, and it is worth knowing about.
What is supported
Windows x86_64, macOS on Apple silicon and Intel, and Linux x86_64 with webkit2gtk-4.1. The project does not declare a minimum operating system version, so this page does not invent one — if an install fails on yours, that is worth reporting.
It is alpha
Solid and heavily tested, without production mileage. Start with low-stakes work, and keep the sandbox in mind for anything that touches real systems.
