I've been working on a code review app for GitHub called Crocodile for about a year. I used to work at Microsoft where we used a tool called CodeFlow for reviewing code and I missed it after I left. I know many other ex-Microsoft engineers feel the same. Here are some of the distinguishing features of Crocodile that are inspired by CodeFlow:
* Comments float above the code instead of being inline. Long discussions that are displayed inline make it really hard to review the code.
* Comment on any text selection in the file, even a single character.
* Comments don't get lost when code changes. I hate it when comments become "outdated" because I rebase or the line is edited.
I also implemented lots of features that I wish CodeFlow had which you can read more about on the blog. [1]
For those curious about the tech stack: it's mostly written in Go with Alpine.js, HTMX, and Tailwind CSS for the frontend. For storage I use PostgreSQL, S3 compatible object storage, and Redis for caching. I use Pulumi for infrastructure provisioning and Kubernetes deployments. Everything is hosted on DigitalOcean.
Feedback is welcome!
