devshell is a Nix-based tool for defining per-project developer environments, configured via TOML and integrated with nix-shell, direnv, and nix flakes. It provides a clean shell environment with project-scoped dependencies so contributors can start working within minutes of cloning a repo.

Use cases

• set up per-project development environments with nix
• onboard new contributors with a single command
• replace virtualenv-style workflows for all languages
• get a clean shell environment without stdenv pollution
• integrate dev shells with direnv and nix flakes
• define project dependencies in a toml file

When to choose

• your team uses Nix and wants reproducible, per-project dev shells
• you want a cleaner environment than mkShell with fewer exported variables
• you need multi-language project dependencies managed declaratively

When to avoid

• you don't use or want to adopt the Nix package manager
• you need Windows-native development environments
• you want a fully stable, guaranteed API (project is marked unstable)
