At its core, plz.review is an interface to your team’s Git code changes and the reviews associated with those code changes.
It serves as a layer on top of your GitHub repo that is focused on the task of creating reviewable code changes, and letting you review your team’s code changes, in a more pleasant and productive way.
At Bit Complete we work on a lot of projects hosted on GitHub. While GitHub's PR model is simple to use, it creates a workflow where the typical output is a large pull request. These PRs often address many dimensions of a feature or fix all at once, and are very unwieldy to review.
We longed for power tools like the internal code review apps at Google (Critique/Gerrit) and Facebook (Phabricator). We wanted our tools to encourage meaningful commits as checkpoints for feedback. We wanted a workflow encouraging more incremental output that's easier on reviewers.
This wonderful blog post by Jackson Gabbard goes into a lot of the specifics of how we prefer to work, and why we felt a tool that bridges this workflow with GitHub was needed.
We’ve now used plz on many of our own projects. We think it’s a big step forward for developer productivity and want to share it with the world!
