How does ultrareview differ from `/review`?

`/review` runs locally in your session with a single-pass review, while `/ultrareview` runs remotely in a cloud sandbox using a fleet of agents for multi-agent, independent verification. The latter takes longer (5–10 min) and costs extra after free runs, but provides deeper analysis.

Is ultrareview available on all plans?

No, ultrareview is available for Claude Code Pro and Max plans. Team and Enterprise plans do not include free runs and are billed as extra usage.

How much does ultrareview cost after the free runs?

After the 3 free runs (through May 5, 2026), each ultrareview costs roughly $5 to $20, billed as extra usage via `/extra-usage`.

Can I track the progress of a running ultrareview?

Yes, you can use the `/tasks` command to track a running ultrareview.

What is the typical duration of an ultrareview?

Ultrareview typically takes about 5 to 10 minutes, depending on the size and complexity of the code changes.

What is Claude Code /ultrareview

Ultrareview is a cloud-based code review tool that deploys a fleet of parallel AI agents to analyze your branch or pull request. Each agent independently verifies potential bugs before reporting them, providing deep, multi-agent analysis that catches issues a single pass might miss. Designed for Claude Code Pro and Max users, it offers 3 free runs through May 2026, then charges roughly $5–$20 per review as extra usage.

Key Features

Multi-agent parallel review in a remote cloud sandbox

Independent verification of each bug by separate agents

Supports current branch or specific GitHub PR with `/ultrareview <PR#>`

Roughly 5–10 minute duration for comprehensive analysis

Free runs included for Pro and Max plans through May 5, 2026

Use Cases

Developers who need a deep, pre-merge code review for substantial changes
Teams using Claude Code Pro/Max who want to catch bugs before deployment
Engineers reviewing large pull requests who want independent verification of issues
Startups aiming to improve code quality without manual overhead

Why do startups need this tool?

Startups often move fast and have limited engineering resources, making it easy to miss subtle bugs. Ultrareview provides a deep, multi-agent code review in the cloud, catching errors before they reach production without requiring manual code review overhead. Its pay-per-use model after free runs suits startups that want to scale review quality without a large upfront investment.
