AI code review tools, compared
AI code review tools comment on a pull request before a person reviews it. They differ in what they check, which model they run and how they charge: CodeRabbit Essentials is $24 per developer a month billed annually,[1] Greptile Pro $30 per seat a month,[2] Cursor Bugbot about $1.00–$1.50 a run[3] and GitHub Copilot code review draws on your Copilot plan's AI credits.[4]
On the same 50 open-source pull requests, which hold 158 known issues, the Qodo app had the highest F1 (58.5%), then Cursor Bugbot (51.4%), Greptile (51.1%), the model IonWarp's Code Review runs (46.7%) and CodeRabbit (42.2%). Copilot code review is not in the benchmark.[5] IonWarp charges one workspace price: Pro is $49/mo with 5 seats included, and Starter is free.
IonWarp gets you:
- $49/mo for 5 developers, one workspace price on the Pro plan
- AI Architecture Review on the PRs that need it
- Security Review on the PRs that need it

Frequently asked questions
An AI model reads a pull request's diff and the code around it and comments on defects before a human reviews it. AI-powered code review tools differ in how many kinds of review they run — bugs only, or also security, performance, docs and architecture — and in which models they use.
Three ways: per developer (CodeRabbit, Greptile), per review run (Cursor Bugbot) or from the AI credits in an existing plan (GitHub Copilot). IonWarp charges per workspace: Pro is $49/mo with 5 seats included, and Starter is free.
On our benchmark of 50 pull requests, the Qodo app had the top F1 (58.5%) and found the most known issues, 98 of 158. CodeRabbit found 94 but also filed the most findings that matched none (194). The model IonWarp's Code Review runs scored 46.7%.
Copilot code review does not support model switching, and CodeRabbit and Greptile list no model choice on their pricing pages. IonWarp pins a model per reviewer (DeepSeek v4.1 Flash, GLM 5.3 Flash, GPT 5.6 Luna Pro), and you can switch any reviewer's model in settings.
IonWarp's Starter plan is free forever for 3 seats with unlimited repos. The other tools list their free tiers and trials on their own pricing pages.
