Architecture

Snix is more decoupled than the existing, monolithic Nix implementation.

In practice, we expect to gain several benefits from this, such as:

• Ability to use different builders
• Ability to use different store implementations
• No monopolisation of the implementation, allowing users to replace components that they are unhappy with (up to and including the language evaluator)
• Less hidden intra-dependencies between tools due to explicit RPC/IPC boundaries

In addition to many individual backend implementations, Builders and Store backends also provide a gRPC server and clients, allowing to plug in your own implementation.
