Install
Get Tycho running in one line.
Free, open source, no account. The verifier runs locally and offline. Pick your method, paste, and go.
curl -fsSL https://swail.dev/tycho/install.sh | sh
The one-line installer builds the standalone binary for macOS and Linux (no
Python needed). On Windows, or any machine with Python, install with uv, pipx, or
npm above — each drops the tycho command in its own isolated environment.
Then wire the hook into your agent, once:
tycho init
Free, forever
The local verifier is open source under Apache 2.0. Unlimited checks, no account, no network, no LLM in the trust path.
Runs offline
Every check runs on your machine: git, the filesystem, process exit codes, and the harness event stream. Nothing leaves your compute.
Verifiable itself
Every release ships a published SHA256 per platform, and the installer verifies it before installing. Verify checksums →
