Use this, not that: AI pull-request review
An AI reviewer is a second reader, not a substitute for a human. These products differ in whether review is the whole product or a feature of a broader Git or GitHub plan.
First pick
CodeRabbit
Use CodeRabbit when you want a specialist reviewer with a public official rate card (Essentials $24/user/mo annual or $30 monthly; Team $48/$60; Advanced $72/$90), a free plan, and free Team features for public open-source repos. Extra reviews are officially $0.25/file after included limits.
Use this, not that
CodeRabbit
Use this when
Review quality on GitHub (or documented Git hosts) is the job, including a free path for public OSS.
Not that when
You already bought Copilot primarily for review, or you mainly want stacked-PR workflow rather than a review bot.
Graphite
Use this when
You want stacked pull requests and are fine with AI review as part of that workflow. Official Hobby is free; Starter is $20/seat/mo annual (limited reviews); Team is $40/seat/mo annual (unlimited reviews).
Not that when
You only want a review bot and do not care about Graphite’s stacking workflow.
GitHub Copilot
Use this when
You already pay for Copilot and want review inside GitHub without adding a second vendor.
Not that when
You want a specialist review product with a standalone free OSS path, or you are not on GitHub.
