If you already pay for Copilot Business ($19/user/mosrc) Code Review is $0 marginal until AI Credits overage bites. CodeRabbit ($24/dev/mosrc) delivers tighter, more opinionated comments and works on GitLab + Bitbucket + Azure DevOps. Run Copilot first if you have it; switch to CodeRabbit when comment quality forces it.

1-Since 1 Jun 2026 Copilot Code Review consumes AI Credits per reviewsrc. Most 10-dev teams stay inside the Business allotment; high-volume review-everything-twice policies start to pay overage.
2+CodeRabbit's seat bundles tokens. PR volume can spike without a surprise bill.
1+CodeRabbit: opinionated, multi-suggestion, often catches refactor opportunities. Comment cadence is dense.
2+Copilot Code Review: terser, more focused on factual defects. Less prose, more inline patches.
3Both are good. The right answer is often to run both side-by-side until habit and signal-to-noise tell you which to keep.
1-Copilot Code Review: GitHub strong, Azure DevOps weaker, GitLab absent, Bitbucket absent
2+CodeRabbit: all four platforms first-class
