Comparison

Gary vs CodeRabbit

coordination vs. code review

CodeRabbit is an AI-powered code review tool that analyzes PRs for bugs, security issues, and code quality. Gary is an AI staff engineer that coordinates across GitHub, Linear, and Sentry and proactively flags operational issues. They solve different problems and work well together.

does Gary replace CodeRabbit?

no. they're complementary. CodeRabbit reviews the code itself — bugs, security issues, style. Gary handles everything around the code: ticket context, who should review it, whether it conflicts with other work, and whether the linked Sentry errors are related. CodeRabbit is in the linting lane. Gary is in the coordination lane.

The verdict

these tools solve different problems. CodeRabbit reviews the code for quality. Gary coordinates the process around the code. the best setup is using both: CodeRabbit catches bugs in the diff, Gary makes sure the reviewer has the ticket context, knows who else is touching those files, and flags if the linked Sentry errors are related. they don't overlap.
