Tvix

Tvix is a new implementation of Nix, a purely-functional package manager. It aims to have a modular implementation, in which different components can be reused or replaced based on the use-case.

Tvix is developed as a GPLv3-licensed open-source project by TVL, with source code available in the TVL monorepo.

There are several projects within Tvix, such as:

• //tvix/castore - subtree storage/transfer in a content-addressed fashion
• //tvix/cli - preliminary REPL & CLI implementation for Tvix
• //tvix/eval - an implementation of the Nix programming language
• //tvix/nar-bridge - a HTTP webserver providing a Nix HTTP Binary Cache interface in front of a tvix-store
• //tvix/nix-compat - a Rust library for compatibility with C++ Nix, features like encodings and hashing schemes and formats
• //tvix/serde - a Rust library for using the Nix language for app configuration
• //tvix/store - a "filesystem" linking Nix store paths and metadata with the content-addressed layer
• ... and a handful others!
