Your toolchain deserves a home.

Alpha: This project is in alpha. The configuration API is not yet stabilized and may change between versions.

Every stack comes with a configuration tax. You pay it on the first project, then the second, then every time a tool updates—and it breaks differently in each repo. datamitsu exists so you pay this tax only once.

A platform for building reproducible, security-first development tool distributions. It downloads, verifies (SHA-256), and manages binaries and runtime-managed tools across platforms, using JavaScript-powered configuration with inheritance and chaining. Install one package, get everything configured.

# Build from source
