Declarative, reproducible development environments built with Nix to eliminate setup drift and reduce onboarding friction for developers.
Run devenv init to create a new project, then run devenv shell to enter the dev environment and devenv up to start services.

To create a reproducible development environment using Nix, define packages, environment variables, and startup hooks in devenv.nix and devenv.yaml, then run devenv shell to enter the consistent dev shell. This eliminates setup drift across multiple projects and machines.
The best way to isolate project dependencies and avoid setup drift is using a declarative Nix dev environment. By defining toolchains and variables in devenv.nix and pinning them via devenv.lock, you ensure consistent shells across machines.
To start a new project with devenv and run services, execute devenv init to generate configuration files, then use devenv shell to enter the environment and devenv up to start your defined processes and services immediately.
Yes, devenv works directly with direnv to automatically activate the development environment on shell entry. This integration keeps project context isolated and seamlessly applies configured packages and variables.
Yes, you can manage pre-commit hooks and language toolchains in a Nix dev environment. Devenv allows you to configure these components declaratively and pin their versions using devenv.lock for reproducible setups.
