diffray: Pricing, Features & Best Use Cases

Multi-agent AI code review for pull requests on GitHub, GitLab and Bitbucket, free for open source.

diffray homepage screenshot, coding AI tool

Our take: diffray suits small development teams and open-source maintainers who want multi-agent AI pull request review on GitHub, GitLab or Bitbucket, free for public repositories.

Main limitation: Paid plans are per developer seat, performance figures are from internal testing, and teams above 50 developers must contact sales.

Is diffray right for you?

diffray suits small development teams and open-source maintainers who want multi-agent AI pull request review on GitHub, GitLab or Bitbucket, free for public repositories. Based on the vendor's documentation, not on a hands-on test.

Best for: Small development teams

Also a good fit for

  • Open-source maintainers
  • Teams with noisy AI review tools

Consider another tool if paid plans are per developer seat

Or if

  • Performance figures are labeled internal testing
  • Setup requires installing a GitHub App

What is diffray, and how does it work?

diffray reviews pull requests with several specialized AI agents that investigate the codebase instead of commenting from the diff alone. It is installed as a GitHub App and posts findings with file paths and line numbers. The pricing page lists a free plan for public repositories and paid per-developer plans with unlimited reviews. The site lists GitHub, GitLab and Bitbucket integrations.
