Installation

Prerequisites

Go 1.25.2+ — Required to build from source
Git — datamitsu uses your git root to locate configuration files and manage project-scoped caches
Platform support: Linux (amd64, arm64), macOS (amd64, arm64). Windows support is available but requires Developer Mode for symlinks.

Clone the repository and build:

git clone https://github.com/datamitsu/datamitsu.git
cd datamitsu
go build

This produces a datamitsu binary in the current directory. Move it to a directory in your PATH:

mv datamitsu /usr/local/bin/

If you have pnpm installed, you can also build via:

pnpm build

Check that datamitsu is available:

datamitsu --help

You should see the available commands listed, including exec, init, check, setup, and others.

datamitsu stores data under ~/.cache/datamitsu/ (or $XDG_CACHE_HOME/datamitsu/), split into two subdirectories:

store/ — Downloaded binaries (.bin/), runtime binaries (.runtimes/), runtime-managed app environments (.apps/), remote configs (.remote-configs/)
cache/ — Per-project tool caches (projects/), verify state (.verify-state/)

You can view the cache path with:
