Macroscope vs CodeRabbit (vs Greptile): Pricing, What Each Reviews, and Which Is Cheaper for a Team

Prices, limits and platform support below come from the three vendors' public pricing and comparison pages as read in early November 2026. All three change their plans often, and Greptile has changed its model since our Greptile vs CodeRabbit post in October; check the live pages before you sign anything.

Three tools, three meters

Ask “is CodeRabbit or Macroscope cheaper?” and the honest first answer is: for what? The two tools (and Greptile, which keeps turning up in the same searches) do not charge for the same unit. Macroscope meters the kilobytes of diff it reviews, CodeRabbit sells a seat per developer per month, and Greptile sells credits that a review consumes at different rates depending on depth. The same team can come out cheapest on any of the three depending on how many pull requests it opens, how big they are, and how often it asks for a second look.

So this post does two things: it lays out what each product actually posts on a pull request, because a cheaper review that your team ignores is not cheaper, and then it works the numbers for three team sizes with the assumptions written down so you can swap in your own.

What “review” means in each product

Macroscope: fewer comments, aimed at runtime bugs

Macroscope is a GitHub App that reviews pull requests with full-repository context and posts inline comments naming the file, the risk and, where it can, a suggested diff. It also writes a PR description covering what changed and which tests cover it, can auto-approve low-risk PRs (opt-in per repository), and offers a “fix it for me” reply that opens a fix branch and iterates until CI passes. Its pitch is restraint: the company quotes an average of 2.55 comments per PR on its own usage against 10.84 for CodeRabbit, and a bug-detection rate of 48% on a 118-bug benchmark that it built and runs itself. Treat the benchmark the way you would any vendor benchmark, but the low comment count is the characteristic to notice. It is GitHub-only, runs as a managed service on Google Cloud, and has no self-hosted option.

CodeRabbit: the review platform

CodeRabbit is the broadest of the three: summaries and walkthroughs, sequence diagrams, line comments, one-click fixes, a CLI and IDE integration, pre-merge checks, chat in the PR thread, and on the Advanced tier a security review and architecture impact notes. It supports GitHub, GitLab, Bitbucket and Azure DevOps. The trade-off is volume and the tuning work that follows, which the CodeRabbit pricing explainer and the fair usage policy post both cover.

Greptile: the whole-repo index, now sold by the review

Greptile indexes the entire repository into a graph and reviews each PR against it, going after cross-file logic bugs. In October its Pro plan was $30 per seat with 50 credits included; as of early November the pricing page lists Pro at $1 per credit with no seat fees, credits shared across the organisation, unlimited developers and repositories, and a 14-day trial. A Base review still costs 1 credit, Plus 3 and Apex 10. That is a meaningful change for small teams and it is why the numbers below differ from our earlier comparison.

Pricing models side by side

Worked examples: 5, 20 and 50 developers

Assumptions, so you can argue with them: each developer opens 20 pull requests a month, every PR gets exactly one automated review, and the average Macroscope review is the vendor's own 19 KB figure ($0.95). CodeRabbit is on the annual Essentials price; Greptile uses Base reviews. The fourth column is PURA's flat platform fee, which is metered by reviews and excludes model cost because you bring your own keys (more on that below).

Three things jump out. First, at this volume Macroscope, CodeRabbit and Greptile land within about 25% of each other, which means the assumptions matter more than the vendors' marketing. Second, the ranking flips with PR count: a developer who opens 30 average PRs a month costs $28.50 on Macroscope and $30 on Greptile Base but still $24 on CodeRabbit, so high-throughput teams drift towards the seat. Third, depth is expensive on Greptile: switch the 20-developer team to Plus reviews and the bill is $1,200; Apex on every PR would be $4,000, which is why most teams reserve it for migrations, auth and payments.

The hidden costs in each model

• Re-reviews. Macroscope bills every review, so a PR that gets five rounds of commits can cost five times the headline. Greptile spends a credit each time too. CodeRabbit absorbs re-reviews in the seat, subject to the hourly cap.
• Diff size. A generated lockfile, a vendored dependency or a snapshot update is cheap on a seat and expensive by the kilobyte. Macroscope lets you ignore files and cap spend per PR at $50 by default; set both before the first big refactor lands.
• Who counts as a developer. Seat pricing usually counts anyone whose PR was reviewed, including the contractor who opened one PR this quarter. Check the definition before multiplying by headcount.
• The hourly cap. CodeRabbit's five reviews per developer per hour on Essentials is fine on average and painful on release day when one engineer opens a dozen PRs; reviews queue rather than fail.
• Model cost on BYOK tools. Flat-fee, bring-your-own-key reviewers look cheap in the table because the inference bill goes to OpenAI, Anthropic or Google directly. That is a real cost; it is just one you control and can see.

Which to choose

Pick Macroscope if you are on GitHub, your PRs are small and frequent, and your main complaint about AI review is noise; the per-KB meter rewards exactly that shape of work. Pick CodeRabbit if you need GitLab, Bitbucket or Azure DevOps, or if your team opens enough PRs per person that an all-you-can-review seat is the cheaper deal, and you are prepared to tune the comment volume down. Pick Greptile if your defects are cross-file and you want the deep Apex pass available on demand, paying for depth only where it matters. Whatever you pick, trial it on the repository you worry about, not the clean one; the trial guide explains how to make two weeks tell you something, and the broader CodeRabbit alternatives round-up covers the tools that did not make this table.

Where PURA fits

All three tools above are managed services on their public plans: your diff, and for Greptile and Macroscope your indexed repository, is processed in the vendor's cloud on the vendor's model. PURA is for teams whose answer to “where does the code go?” has to be “nowhere”. It is self-hosted on your own infrastructure, BYOK with your own OpenAI, Anthropic or Google keys, and priced as a flat platform fee metered by reviews: Starter at $39 a month for 100 reviews, Scale at $99 for 400, Pro at $199 for 1,000, Enterprise above that, with budgets per repository, team and provider so the model spend stays where you put it. The full plan list is on the pricing page. It is GitHub-only, like Macroscope, and it is not a platform: it posts one ranked review per PR. If a managed service is acceptable and you want Macroscope's quiet reviews, CodeRabbit's packaging or Greptile's index, buy one of those. If the deployment model is the requirement, PURA is the comparison worth running next.
