Code TerrierCode Terrier vs GitHub Copilot code review
GitHub Copilot code review is built into Copilot Business and Enterprise plans ($19–39/user/month). Since 2026-06-01, private-repo reviews consume Actions minutes from your CI quota plus AI credits — and review stops entirely when credits run out. Code Terrier starts free on a shared pool (50 credits per period), with no shared credit pool to drain.
The structural differences that matter: Code Terrier's architecture supports up to three model families; the current shared pool uses one configured model, verifies findings independently, and re-checks later pushes in auto mode. Copilot's review budget is shared with all your CI usage, making its per-review cost undisclosed and variable.
| Criteria | Code Terrier | GitHub Copilot code review |
|---|---|---|
| Pricing | Free 50-credit pool, Pro $5/$50, or BYOK | Included in Copilot Business/Enterprise ($19–39/user/month); uses Actions minutes + AI credits |
| Review budget | No shared quota to drain | Shared org credit pool + Actions minutes |
| Review models | Architecture up to 3; shared pool uses 1 today | Single model |
| Verification | Independent verifier (maker/checker) | None |
| Approves or auto-merges | Never | Configurable |
| Replies to comments | No — quiet review loop | Yes — conversational loop |
The review architecture supports up to three model families. The current shared pool uses one configured model; near-duplicate findings are merged when multiple reviewers are configured, then the verification stage checks line legality before publication.
A single model reviews the PR as part of Copilot. No independent maker/checker verification.
Free shared model pool or BYOK. No shared credit pool — review budget is not competing with your CI usage.
Since 2026-06-01, private-repo reviews consume Actions minutes from the CI quota plus AI credits. Heavy users can drain the shared org pool, and review stops entirely when credits exhaust.
A quiet review loop: findings on exact lines, in auto mode, a new commit starts the next review, no thread replies. Precision over recall — no comment on clean changes.
A conversational loop that replies to comments. Integrated into the IDE/PR flow you already use, but the per-review cost is undisclosed and variable.
