CodeRabbit vs Greptile vs SlopScore for Code
These tools do different jobs. CodeRabbit and Greptile are AI reviewers: they read your PR with a language model and comment on logic, bugs and design. SlopScore for Code is a deterministic gate: it runs fixed checks for the mistakes coding agents make most, in your own CI, for free.

What each one catches
| AI reviewers | SlopScore for Code | |
|---|---|---|
| Logic bugs, design problems | Yes, often well | No |
| Placeholder comments that drop code | Sometimes | Always (error) |
| Imports missing from the manifest | Sometimes | Always, checked against package.json / requirements |
| Same result every run | No | Yes |
| Code leaves your runner | Yes (sent to the vendor) | No |
| Cost grows with | Seats and review volume | Nothing (CLI) / flat per org (hosted) |
How to use them together
Run SlopScore for Code first, as a required check. It fails fast on the obvious agent mistakes, so the expensive reviewer (human or AI) only sees PRs worth reading. Teams on Greptile's per-review pricing save credits too, because sloppy PRs get fixed before a review is triggered.
When SlopScore for Code alone is enough
Small teams and agencies that want a guardrail on agent output without paying per seat, and anyone who can't send code to a third party.
Try it on a public PR or add the Action.
