Macroscope catches more bugs than CodeRabbit, with 4X less noise

The #1 CodeRabbit alternative. Macroscope reviews every pull request, catches real bugs and suggests the fix. 40% of PRs are auto-approved across all customers, so your team only reviews what actually needs attention.

Real bugs, not nitpicks. Macroscope flags correctness issues worth fixing instead of style noise, and installs on GitHub in under five minutes.

Macroscope is usage-based: you pay per review, not per seat. CodeRabbit Pro starts at $24 per user, per month. Start with $100 in usage credit.

We've used just about every AI-driven PR assistant out there: the signal to noise from Macroscope is the best I've seen. The PR descriptions are better than what we would have written by hand, and when it flags an issue it's almost always a real bug.

Macroscope is like having a distinguished engineer tech lead who's read every diff, understands every project, and can answer any question about your codebase instantly. We can finally focus on shipping instead of process.

Within 24 hours of installing Macroscope, engineers on my team said things like, 'wow, that is scary accurate for a very complex thing,' and, 'much better than my own linear summary or Git commit.'

Higher Signal Reviews graphic

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 uses Abstract Syntax Trees (AST) to create a graph-based representation of how your codebase works, allowing it to find hard-to-detect bugs while avoiding false-positives.

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.

Frequently Asked Questions

Macroscope builds a graph-based representation of your entire codebase. This approach 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 and averages around $0.95 per review. You pay per pull request reviewed, not per developer seat, so your cost tracks how much code you actually ship rather than how many people are on the team. New teams start with $100 in usage credit.

Linters and static analysis match patterns inside a single file. Macroscope builds a graph-based representation of your whole codebase using Abstract Syntax Trees, 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 around 40% of pull requests end up auto-approved 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 had the highest detection rate of the tools tested, with 4X less noise than the next closest. 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.
