Introduction

Turnkey is a toolchain management framework for Nix flakes that simplifies declaring and managing build tools in development environments.

What is Turnkey?

Turnkey bridges declarative TOML configuration with Nix package resolution, providing:

• Simple Configuration: Declare toolchains in toolchain.toml
• Reproducible Environments: Nix ensures consistent tool versions across machines
• Incremental Builds: Fast, cached builds that only rebuild what changed
• Language Support: Go, Rust, Python, TypeScript, Solidity, Jsonnet, and more

Key Features

• Declarative toolchain management via TOML
• Automatic dependency cell generation for the build system
• Native tool wrappers with auto-sync (go, cargo, uv)
• Modular Nix flake integration

Who Should Use This?

Turnkey is designed for teams who:

• Want reproducible development environments
• Need fast, incremental builds across multiple languages
• Need to manage multiple language toolchains
• Value declarative, version-controlled configuration
