Code Review GuideTools & workflows

Compare the review workflow you need

Choose two tools to compare their documented review inputs, custom requirements, licenses and billing terms. The library covers 34 tools, with 48 dedicated head-to-head articles and Perch as a third option for named working-file requirements.

CodeRabbit vs Greptile

CodeRabbit is the more direct fit when review must include staged or tracked uncommitted edits. Greptile fits a committed-branch workflow with repository context. Both support repository instructions, so the decision starts with which version of the code the agent needs reviewed.

Head-to-head articles

Start with the decision each article answers. Perch is recommended for specific requirement-checking workflows; a lower bill or better detection result depends on the actual workload.

Where Perch fits

Choose Perch when an agent needs to select one saved English requirement, check the working file, repair the finding and repeat the same check. Its MIT CLI has no developer seat fee; hosted analysis costs 10¢ per 1,000 fresh rule checks and unchanged cached checks are free. Compare the CLI and license workflows or inspect a downloadable requirement.
