A CLI for Crunchy Bridge with very good tab completion.

cb tab animation


  • For homebrew (on macOS or linux) brew install CrunchyData/brew/cb. This will install both cb and the fish shell tab completions for you.
  • For others, download the latest release, put it somewhere in your path, and be sure to manually install shell tab completions from the completions directory.

Getting started

First get your application ID and application secret from

Then run cb login to register the CLI with your Crunchy Bridge account.


Once you are logged in, you can run cb list to see all of your clusters, and cb psql <cluster id> to securely connect to your database or cb scope to run health checks against it. There are many more commands that you can use to manage things such as log destinations, firewall rules, and more.

To see what commands are available run cb --help, and to see more detailed information for a given command add --help to it, for example cb create --help.

If you use the fish command line shell and have the completions installed for you (either automatically through homebrew or otherwise), nearly all arguments can be intelligently completed for you. This includes all cluster IDs available to just your account, in addition to normal subcommands and flags. Also where possible the current arguments you've given are taken into consideration. For example if you're creating a new cluster on AWS, instances sizes on Azure or regions in GCP will not be shown.


Install dependencies: crystal

You can run quick checks by executing src/ directly. While this can be handy, it is slow because the executable is being built each time, then executed. To build a development version run make or shards build. The binary will be at bin/cb by default. There is a helper script which puts the local bin directory in your path so the cb in that directory will be ran, as well as an scb alias for running src/ It will also set up completions for each.

crystal tool --format will format the code as required. It is useful to have your editor run this for you on save.


You can run crystal spec to run all of the specs, or make test to also run linting checks.
