Get TASS.
Community Edition (free, Apache-2.0)
The engine, CLI, MCP server, minimal local web GUI, and reproducible-project container. Available now from the source repository. The engine and CLI have zero runtime dependencies; Node 18 or newer is the only requirement. Runs on Windows, macOS, and Linux.
Get it from github.com/SIM-DAD/tass
Or install it in one command with npm: npm install -g @simdad/tass-cli, then tass help. The @simdad/tass-cli package carries the engine and every Community capability.
GUI Edition (desktop workbench, beta)
The no-code desktop workbench is in closed beta. Beta installers are distributed directly to beta participants; the program is free for its duration and open to researchers currently affiliated with a university or an established research institution.
Apply from your institutional email
At public launch, signed release installers and their SHA-256 checksums will be published at github.com/SIM-DAD/tass-releases.
