Strengths
- ✓Full-repo context — catches issues spanning multiple files
- ✓Custom rules engine for team conventions
- ✓Strong at architectural feedback
Trade-offs
- •Premium pricing aimed at funded teams

Strengths
- ✓Zero extra setup if your org already uses Copilot
- ✓Native GitHub integration — no third party
- ✓Fast reviews
Trade-offs
- •Requires Copilot Business/Enterprise seat for everyone

Which one should you pick?
Pick DevReview if…
- • You're a solo dev or small team wanting predictable $9-$29/mo pricing
- • You want setup in 2 minutes, not 2 hours of config
- • You're tired of AI reviewers that flag every trivial nit
- • You need fast reviews (<60s) to stay in flow
Pick a competitor if…
- • CodeRabbit: You need GitLab/Bitbucket support or a mature learning-mode AI
- • Greptile: You want whole-repo context and have funded budget
- • Copilot: Your org already pays for Copilot Business/Enterprise

Frequently Asked
Why is DevReview cheaper than CodeRabbit or Greptile?
We optimize for solo devs and 2-10 person teams who don't need per-seat billing, SSO, SOC2 audits, or enterprise legal review. Our unit economics work because we run lean and keep the product focused on one job: fast, high-signal PR reviews.
Can I use DevReview on private repos?
Yes. DevReview installs as a GitHub App and works on both public and private repositories. Code is sent to Anthropic's Claude API for the review and is not retained after processing.
Which AI model powers DevReview?
Claude Sonnet 4.5 by Anthropic. We chose it for its strong code-reasoning benchmarks and willingness to say "this looks fine" instead of inventing issues.
What languages does DevReview support?
All major languages including TypeScript, JavaScript, Python, Go, Rust, Ruby, Java, Kotlin, Swift, C/C++, C#, PHP, Scala, and more. Our prompts include language-specific checks (e.g., mutable default args in Python, goroutine leaks in Go, unwrap misuse in Rust) to cut false positives.
Does DevReview replace human code review?
No — and that's by design. Use DevReview to catch the easy stuff (typos, missing error handling, obvious bugs, security patterns) before your teammate looks at the PR. It's a first pass, not a final word.
