Tool Breakdown
CodeRabbit
CodeRabbit's free tier — unlimited public/private repos with no credit card required, plus fully free line-by-line reviews on open-source projects — makes it the lower-risk starting point for most teams. Greptile's full-codebase indexing is genuinely differentiated for catching cross-file bugs, but its $30/seat/mo entry price with no general free tier is a real cost for teams still evaluating AI code review.
- Free plan supports unlimited public and private repos with no credit card required for PR summarization
- Full line-by-line reviews are free forever on open-source and public repos, plus via the VS Code extension and CLI
- Pro Plus tier includes a 14-day free trial with no card required, letting private-repo teams test the deeper tier risk-free
- Reviews the PR diff rather than indexing the full codebase, so cross-file context that Greptile captures can be missed
- Full private-repo line reviews require a paid Pro or Pro Plus plan
Greptile
Greptile is an AI code review agent that indexes an entire codebase rather than just the diff, aiming for full-context PR review across GitHub and GitLab, with a self-hosting option available.
- Full-codebase indexing lets Greptile flag issues caused by interactions with code the pull request doesn't directly touch
- Self-hosting option available for teams that need code to stay inside their own infrastructure
- Fee waivers exist for qualifying MIT/Apache-licensed non-commercial open-source projects and pre-Series-A startups
- No general free tier — every seat costs $30/mo with 50 review credits included, additional credits billed at $1 each
- No public commission rate disclosed for its Partner Program, only a directory listing
Frequently Asked Questions
Does Greptile have a free tier like CodeRabbit? +
Not a general one. Greptile starts at $30/seat/mo with no free plan for typical commercial use, though it offers 100% fee waivers for qualifying MIT/Apache-licensed non-commercial open-source projects and 50% off for pre-Series-A startups under $2M revenue. CodeRabbit's free tier, by contrast, supports unlimited public and private repos and includes fully free line reviews on open-source and public repos.
What's the real difference between how CodeRabbit and Greptile review code? +
CodeRabbit primarily reviews the pull request's diff with configurable rules, chat, and summaries. Greptile indexes the entire codebase before reviewing a PR, which lets it catch issues caused by code outside the changed lines — a meaningfully deeper form of context that diff-only tools can miss.
Can I self-host either CodeRabbit or Greptile? +
Greptile offers a self-hosting option for teams that need code to remain inside their own infrastructure. CodeRabbit is used primarily as a hosted service integrated with GitHub, GitLab, Bitbucket, or Azure DevOps; check current documentation for the latest deployment options before assuming self-hosting parity.
