Comparison
Rams vs Greptile
Greptile understands your whole codebase. Rams understands design. Different kinds of depth. They complement each other.
Greptile is an AI code reviewer known for whole-codebase context: it indexes your repository so its PR comments understand how a change fits the larger system, catching cross-file issues and architectural inconsistencies a file-local reviewer would miss.
Rams brings a different kind of depth: not codebase breadth, but design expertise. It reviews the UI layer against 194 rules across 8 categories: accessibility, color, typography, spacing, components, motion, UX, and craft. Greptile reasons about how your code connects. Rams reasons about whether your interface is well-designed. On a UI PR, those are two different questions, and you want both answered.

The bottom line
Greptile gives you breadth-of-codebase context. Rams gives you depth-of-design judgment. They answer different questions about the same PR (how the change fits the system, and whether the interface is well-made), so running both gives UI-heavy teams the most complete review.
Common questions
Does Rams replace Greptile?
No. Greptile specializes in whole-codebase context. Rams specializes in design and accessibility. They are complementary: Greptile for architectural/cross-file reasoning, Rams for design depth on the UI layer.
Does Rams need full-codebase context like Greptile?
No. Rams reviews the UI files in a pull request against a fixed design ruleset, so it does not need to index your whole repo. That keeps it fast and config-free: install the GitHub App and every PR is reviewed.
Which should a design-heavy team choose?
If you must pick one for a UI-heavy product, Rams catches the design and accessibility issues that directly affect users. But the strongest setup is both: Greptile for codebase-wide reasoning, Rams for design depth.
