The AI Code Review Tool That Catches Real Bugs

Your coding agent wrote it. Macroscope checks it. It reads your whole codebase and reviews every pull request, whether Claude Code, Codex, Copilot or a person wrote it, and flags the real bugs instead of style nits.

Safe PRs can be auto-approved and risky ones are held for a human reviewer, the moment the PR opens. Connect GitHub in about a minute.

Usage-based pricing: reviews average 55¢ on Budget and 76¢ on Balanced, never per seat. $100 in usage credit to start. Setup under 5 minutes. SOC 2 Type II.

Reviewing agent-written code

Which AI code review works best on code from Claude Code or Cursor?

Use a reviewer that is separate from the agent that wrote the code. When Claude Code or Cursor reviews its own output, the model grades its own homework. Macroscope reviews every pull request on GitHub, whoever or whatever wrote it, and plugs into Claude Code and Cursor so the agent can fix confirmed bugs before you push.

Inside your agent, before you push

One install adds /macroscope:codereview to Claude Code and /codereview to Cursor, plus Codex and OpenCode. The agent validates each finding, drops false positives, and fixes the confirmed bugs.

Billed in Agent credits at $0.01 per credit, with 1,000 free every month.

On every pull request

The GitHub app reviews each pull request with the context of your whole repository. Approvability auto-approves low-risk pull requests and sends risky ones to a human reviewer.

$0.05 per KB of diff, 10 KB minimum. Reviews average 55¢ on Budget and 76¢ on Balanced. $100 in usage credit to start.

How it compares

On our benchmark of 118 real production bugs (September 2025), Macroscope detected 48.3%, CodeRabbit 45.8%, and Cursor Bugbot 42.4%.

Anthropic's managed Claude Code Review averaged $15 to $25 per review at launch (March 2026), for Team and Enterprise plans, and never approves or blocks a pull request.

High Signal, Low Noise

Macroscope won't spam you with noisy false positives. Using the latest AI reasoning models, Macroscope identifies correctness issues you'll want to fix. It's the only code review tool you won't want to turn off.

Deeply Understands your Codebase graphic

Deep Codebase Understanding

Macroscope reads each change, then explores the surrounding code in your repository to understand how your codebase works, allowing it to find hard-to-detect bugs while avoiding false-positives.

Absorbs context from your tickets graphic

Context from your tickets

Macroscope pulls context from your issue management systems to understand the 'why' behind each change. It evaluates your PRs against their linked tickets and reviews them for issues using that context.

Automated PR Summaries

Concise, AI-generated summaries surface key changes instantly so that engineers spend less time managing pull requests.

Frequently Asked Questions

A reviewer that is separate from the agent that wrote the code. When Claude Code or Cursor reviews its own output, the model grades its own homework, with the same assumptions that produced the bug still in context. Macroscope reviews every GitHub pull request with the context of your whole repository, whoever or whatever wrote it, and its Approvability check auto-approves low-risk pull requests and sends risky ones to a human. It also installs as a command inside Claude Code (/macroscope:codereview) and Cursor (/codereview), so the agent can check findings and fix confirmed bugs before you push. In our benchmark of 118 real production bugs, published September 2025, Macroscope detected 48%, CodeRabbit 46%, and Cursor Bugbot 42%. Pull request reviews cost $0.05 per KB of diff and average 55¢ on Budget and 76¢ on Balanced.

It can, but not as your only check. Anthropic's /code-review command runs in any Claude Code session and is a reasonable quick pass. The weakness is that the reviewing model shares the assumptions of the model that wrote the change, so use a separate reviewer on the pull request as the merge gate. Anthropic's managed Claude Code Review, for Team and Enterprise plans, averaged $15 to $25 per review according to Anthropic's March 9, 2026 launch post, and by design never approves or blocks a pull request.

Yes. One install of the Macroscope CLI adds /macroscope:codereview to Claude Code, /codereview to Cursor, $macroscope:codereview to Codex, and /macroscope-codereview to OpenCode. The agent runs a review of your branch, validates each finding, discards false positives, and fixes the confirmed bugs before you push. CLI reviews bill in Agent credits at $0.01 per credit, with 1,000 free credits every month.

On our benchmark of 118 real production bugs from open source repositories, published September 17, 2025, Macroscope detected 57 (48.3%), CodeRabbit 54 (45.8%), and Cursor Bugbot 50 (42.4%). The benchmark measures bug detection on pull requests regardless of who wrote them. Macroscope runs on every pull request in the repository, whatever editor or agent each person uses, so the same review applies to code from Claude Code, Cursor, Codex, or a person.

Macroscope reads each change, then explores the surrounding code in your repository to understand context beyond the diff. This allows Macroscope to detect subtle bugs that other AI reviewers often miss.

No. Macroscope integrates directly into your existing workflow and is designed to complement your existing tools. Once installed, Macroscope will automatically start summarizing PRs and leaving code review comments directly on GitHub.

Yes. Product managers, engineering managers, customer success teams, and executives use Macroscope to stay informed about what's changing in their product and codebase.

All of them. Macroscope reviews pull requests in every language, so there is no list to check your stack against. Commit and PR summaries, project tracking, and productivity insights work across every language too.

Macroscope is used by startups and enterprise engineering teams alike, from 5-person teams to 100+ engineer orgs.

Teams can get up and running in under 5 minutes. Install the GitHub app, connect Slack (optional), and you're ready! New customers get $100 in usage credit so you can get going right away. It's usage-based, so you only pay for the code you review. Macroscope immediately begins analyzing open PRs and backfilling recent code activity.

Yes. Macroscope installs as a GitHub app and reviews every pull request automatically, posting comments inline the moment a PR opens. Unlike a rules-based bot, it builds a graph of your entire codebase first, so it comments on bugs that matter instead of pattern-matching on style.

Macroscope is usage-based: it bills per KB of diff reviewed, not per developer seat, so your cost tracks how much code you actually ship rather than how many people are on the team. Reviews average 55¢ on Budget and 76¢ on Balanced. New teams start with $100 in usage credit.

Linters and static analysis match patterns inside a single file. Macroscope reads each change in the context of your whole repository, following callers, types and imports across files, so it catches bugs that span files, functions and services, which is the class of bug a linter structurally cannot see. It also means far fewer false positives, because it can tell whether a suspicious line is actually reachable.

Yes, and it is the main reason teams adopt it. When Copilot, Cursor or a coding agent writes most of a pull request, the bottleneck moves from writing code to reviewing it. Macroscope reviews AI-written PRs the same way it reviews human ones, and Approvability auto-approves the low-risk ones so engineers only look at what genuinely needs a human.

It depends what you want it to catch. On our benchmark of real production bugs from open source repositories, Macroscope detected 48% of 118 bugs, the highest rate of the five tools tested. Run the comparison yourself: most teams evaluate on a week of their own pull requests, which is a better signal than any vendor benchmark including ours.

Both, depending on how you use it. As an AI code review platform it reviews every pull request, writes PR summaries, and gives engineering leaders a view of what is shipping. Most teams start with automated PR review on GitHub and adopt the rest later.

Traditional code quality tools score a snapshot of your repository against fixed rules, which is useful for tracking coverage and style but rarely catches a real bug. AI-powered code review reasons about the change itself, in the context of the codebase around it, and tells you what will break. Teams generally keep both: one for hygiene, one for correctness.

Not yet. Macroscope currently supports GitHub, and GitLab and Bitbucket are on the roadmap. If you are on either one, book a demo and we will let you know when support lands.
