Nitro is a speedy local development environment that’s tuned for Craft CMS, powered by Docker.

Learn more at craftcms.com/docs/nitro.

If you’d like to build Nitro directly from source to test a PR or unreleased feature, you’ll need go and make in order to build a CLI binary for your OS.

If you’re on macOS running Homebrew and the Apple developer tools that come with Xcode, it should be quick and straightforward:

1. Run brew install golang.
2. Check out this repository and cd /path/to/your/checkout.
3. Run make local.

Nitro’s dependencies will be downloaded automatically, and the built binary will be moved to /usr/local/bin/nitro.

Make sure that’s exactly what you see when you run which nitro:

$ which nitro
/usr/local/bin/nitro

If you installed Nitro with Homebrew, you might need to run brew unlink nitro so that the system uses the freshly-built binary instead. (To go back to using the Homebrew Nitro binary, use brew link --overwrite nitro.)
