Ultrareview
Multi-agent code review on Anthropic cloud: every finding independently reproduced and verified in a remote sandbox (~5-10 min, ~$5-20/run). 3 free runs for Pro/Max subscribers. Launch from any repo, results tracked via /tasks.
Strengths
- Each finding independently reproduced in a sandbox, eliminates false positives
- Anthropic cloud: runs without local machine, persistent results via /tasks
- 3 free Pro/Max runs, zero cost to evaluate on a real PR
Limitations
- ~$5-20 per run, too expensive for every daily PR
- ~5-10 min latency, not suited for synchronous reviews
- Beta: behavior and pricing may change without notice
Best for
- Critical PRs before a release or main merge, when cost is worth the certainty
- Teams wanting an independent Claude review without setting up a GitHub App
