Devbox 0.4.7 comes with two major new feature requested by users:
Services 2.0, which improves how
devbox servicesworks and allows users to define their own custom servicesFlake Support, which lets users install packages from Nix Flakes hosted on Github, or their own custom flakes
Direnv Integration Improvements, which improves the fidelity and performance of our direnv integration.
To install the latest version of Devbox, visit our Getting Started guide. If you already have Devbox installed, version 0.4.7 will be pushed to you automatically. You can view the full release notes on Github.
Services 2.0: Process Compose and User Services
This release includes a major revamp to devbox services that simplifies defining and managing your own services.
Devbox Services are now backed by Process Compose, an open source process manager that provides an interactive TUI for monitoring your running services. You can start the TUI, along with all your services, by running devbox services up . If you’d rather run your services without starting the TUI, you can run devbox services up -b to start process-compose in the background
You can now define your own custom services and processes in a process-compose.yml. Defining services is useful if you want to easily start your application and or other processes Here is an example process-compose.yaml that can run a Django server:
yaml
version: "0.5"
processes:
django:
# Command to run and manage in process compose
command: python todo_project/manage.py runserver
# Restart policy for the process
availability:
restart: "always"Once your Devbox services are running, you can manage them in the TUI, or using devbox services start|stop|restart. If you have services running in multiple Devbox projects, you can stop them all using devbox services stop --all-projects

Flake Support
Nixpkgs is a massive collection of over 100,000 buildable packages for the Nix package manager. It provides a vast selection of software for developers to leverage in their projects. However, we've heard from our customers that they want to install packages unavailable in Nixpkgs, including packages they've built or customized locally.
With 0.4.7, we’re introducing Flake support. Developers can now install packages from Github-hosted flakes or custom flakes on their local machine. Developers can source packages using a Flake reference, which describes the Flake's location and outputs, in the packages section of their devbox.json. You can even use a Flake reference to install a package from a specific commit or channel of Nixpkgs:
json
{
"packages": [
// Add the default package from the numtide/flake-utils repo on Github
"github:numtide/flake-utils",
// Install a specific output from the nix-community/fenix flake
"github:nix-community/fenix#stable.toolchain",
// Install the hello package from a specific channel(branch) of Nixpkgs
"github:nixos/nixpkgs/21.05#hello",
// Install a package from a local flake.
// This should point to a directory that contains a flake.nix file.
"path:../my-flake#my-package"
]
}You can learn more about Flakes in our documentation, or by checking out some examples in the Devbox Repo:
Direnv improvements
For the last few releases, we’ve focused on improving the correctness and performance of our Direnv integration. In addition to the features listed above, 0.4.7 includes some major improvements to our Direnv integration:
We removed the
use nix .devbox/gen/shell.nixinvocation from the generated.envrcfile. This line was no longer necessary after we moved our backend to Flakes, and removing it should speed up Direnv generation timeGenerated shell environments are now cached. This should speed up startup times for
run,shell, and.envrcactivationWe now run
init_hooksas part of our.envrchook. While this may introduce a small amount of latency when activating your environment, it ensures that the environment created by direnv matches your Devbox shellDevbox will now ensure that the packages specified in your
devbox.jsonare installed when generating your.envrc. This ensures that your init_hooks and environment will run as expected.
If you’ve been using the direnv integration with Devbox, you should regenerate your .envrc to get the latest improvements by running devbox generate direnv --force.
Bug Fixes and Performance improvements
Finally, Devbox 0.4.7 also includes various bug fixes and improvements, including a bugfix that ensures environment variables are retained between package calls.
