What happened
Mixpanel uses Greptile to automatically review pull requests, most of which are written by coding agents such as Claude Code and its in-house agent TAL. Greptile gives codebase-wide feedback before human reviewers look at a PR, and it also reviews TAL's output.
Summary written by usedby from the source page, in English. The figures are those of Greptile and Mixpanel, not ours.
Greptile threaded that needle. It's very cost effective, way better than what we can build, and it was giving that codebase-wide review experience.
The thought of adding an agent to PRs to do code reviews, a potential slop cannon, was extremely contentious. We took the leap and we're so glad we did.
