devenv is a development environment management tool built on Nix. It provides declarative, reproducible development environments with automatic dependency management.
Configuration is defined in devenv.nix, specifying packages, services, environment variables, and scripts. devenv simplifies Nix usage for development environments with a user-friendly API and pre-configured services like databases, language runtimes, and development tools.
The tool supports running services in the background, automatic environment activation with direnv integration, and deterministic builds through Nix's reproducibility guarantees.
