Comparison
Roam isn't competing with your reviewer.
Semantic reviewers (CodeRabbit, Greptile, Qodo) read what the code does. Roam reads what it touches. Most teams keep their semantic reviewer and add Roam alongside.
| Roam | CodeRabbit | Greptile | Qodo | SonarQube | |
|---|---|---|---|---|---|
| Reviews what the code touches (callers, layers, cycles) | Yes | Limited | Limited | Limited | Yes |
| Reviews what the code does (semantics) | Limited | Yes | Yes | Yes | Limited |
| Catches the clone-not-edited bug AI keeps shipping | Yes | Not advertised | Not advertised | Not advertised | Not advertised |
| Runs locally — source never uploaded | Yes | Cloud* | Cloud* | Cloud* | Yes (paid) |
| Publishes EU AI Act Article 12 evidence pack | Yes | Not advertised | Not advertised | Not advertised | Not advertised |
| MCP server for AI agents | Yes (136 tools) | Not advertised | Not advertised | Not advertised | Not advertised |
| Open source | Apache 2.0 | No | No | No | Community ed. |
| Free tier for individuals | Yes, forever | Trial | Trial | Trial | Community ed. |
| Starting price (team tier) | $25/dev/mo | $24/dev/mo** | $30/seat/mo + usage | $30/user/mo | from $32/mo (LOC-based) |

Methodology
Every cell in this table is a verifiable claim. Where we say "Limited" or "Not advertised", we mean we could not find the capability documented on the vendor's public pages as of the verification date below. If you're a vendor and we got something wrong, email [email protected] and we'll update.
Sources verified 2026-05-07
- CodeRabbit: pricing — coderabbit.ai/pricing; product capabilities — coderabbit.ai. Pro tier: $24/dev/mo annual.
- Greptile: pricing — greptile.com/pricing; product — greptile.com. Team tier: $30/seat/mo + $1 per review beyond 50.
- Qodo (formerly Codium): pricing — qodo.ai/pricing; product — qodo.ai. Teams tier: $30/user/mo annual, $38 monthly.
- SonarQube: pricing — sonarsource.com/plans-and-pricing; product — sonarsource.com/products/sonarqube. Cloud Team: from $32/mo (LOC-based, not per-developer).
- Roam: pricing — /pricing; product — homepage; source — github.com/Cranot/roam-code.
How we mark each cell
- Yes — capability documented on the vendor's marketing or docs page
- Limited — partial capability documented, or the capability appears on enterprise-only or undocumented surfaces
- Not advertised — we could not find the capability documented; this is verifiable via vendor pages above
Why "alongside", not "instead of"
Semantic and structural review answer different questions. Semantic review (CodeRabbit, Greptile, Qodo) reads the diff as text and asks: does this change make sense semantically? Are there bugs in the logic?. Structural review (Roam) reads the diff as a graph mutation and asks: what else does this touch? What's the blast radius? Are there clones we should also update?. Most production-quality engineering teams want both signals.
That's why our pricing assumes you keep your existing reviewer: $25/dev/mo for Roam Review is additive to $24-30 for the semantic reviewer, not a replacement.
Want to evaluate Roam alongside your current reviewer?
We'll set up a free 30-day pilot in your repo, run the existing reviewer and Roam in parallel, and quantify which findings each one caught that the other missed. Email [email protected].
