Introduction

Linguo is a cross-platform, multi-language runtime, package, and project manager. Think uv, but for Python, Node.js, Ruby, Rust, Go, and Terraform/OpenTofu.

One binary manages runtime versions, per-project pins, and project workflows for every language, with the same command shape everywhere:

linguo <language> <command>

Why Linguo?

Modern projects rarely stick to one language. You might have a Python backend, a Node frontend, infrastructure in Terraform, and a Rust CLI tool, each with its own version manager and conventions.

Linguo unifies that experience:

• One CLI for every supported language
• Verified downloads: every toolchain is sha256-checked against upstream checksums
• Automatic activation: shell hooks activate pinned runtimes when you cd into a project
• Native project tools: Linguo drives pip, npm, bundler, cargo, and go rather than reimplementing them
