Gitar has been a big help maintaining our OpenMetadata open-source repo. Its reviews are consistently actionable and relevant — not generic bot feedback — catching real bugs and security issues reviewers might have missed.
Gitar vs Macroscope: AI code review compared
Gitar and Macroscope both review pull requests with AI, flag real issues, and generate fixes. They differ on code host coverage, how far CI verification goes, merge governance, and how you pay. This page compares both so you can choose on workflow fit, not benchmark rankings alone.

Gitar Core excludes auto-apply, auto-approve and merge blocking. Cross-repository analysis, functional validation, self-hosted GitLab and bring-your-own model are Enterprise only.
Macroscope bills Check Run Agents, Approvability, “Fix it for me” and the CLI in Agent credits on top of per-KB review charges.
Based on public documentation verified 30 October 2026. Macroscope is a trademark of its owner. “Not confirmed” means the capability is not documented in public sources, not that it is absent.
How do Gitar and Macroscope fix code and verify against CI?
Both tools write fixes. The difference is how much of the loop from finding to green build each one closes on its own.
Gitar
When CI fails, Gitar reads the logs, finds the failing step, and identifies the root cause against your diff. It separates failures your change caused from flaky or unrelated ones, and retries unrelated failures once per commit. If a fix fails, it re-analyzes with the history of earlier attempts, then stops after three consecutive Gitar commits and posts a summary. Gitar never force-pushes and merges only when you enable auto-merge. (CI failure analysis, how Gitar works)
Macroscope
Reply to a review comment (or ask in Slack) and Macroscope opens a branch, commits the change, opens a pull request, uses your GitHub Actions results to validate the fix, and attempts to address failures. Macroscope describes this as iterating until tests pass; its docs do not state a retry limit. Optional auto-merge waits for checks. Macroscope does not write to main directly. For local work, the CLI autoloop reviews, fixes and re-reviews in your working tree or an isolated worktree, up to five iterations. (Fix it for me, CLI)
Human oversight
Gitar fixes land as additional commits you can review or revert, and you write the criteria for what auto-apply may touch. Macroscope fix pull requests request review from the person who asked. Passing CI does not guarantee production safety. A green build shows the checks you defined passed. It does not show the change is correct in cases your tests do not cover.
How does Gitar pricing compare to Macroscope pricing?
The billing units differ, so compare them against your own volume.
Gitar
Self-serve plans charge per user: Core $20 and Pro $40 per month, with annual billing saving 20 percent. On those plans cost follows seats, not diff size, and each plan covers up to 50 users. Enterprise is priced per pull request, as one flat fee per PR regardless of how many fix iterations it takes to reach green, so talk to Gitar sales to model it against your volume. Enterprise has unlimited review volume per author. PR summaries are free, and vetted open-source projects use Gitar free. (plans, FAQ)
Macroscope
Charges for what it processes: $0.05 per KB of diff reviewed, 10 KB minimum per review, so every review costs at least $0.50. Its docs give $0.50 for a 2 KB fix, $1.50 for a 30 KB feature and $35 for a 700 KB refactor. Agent features (Check Run Agents, Fix it for me, Approvability at 30 credits, CLI reviews) bill in credits at $0.01, with 1,000 free credits a month. New workspaces get $100 in usage. Defaults cap spend at $10 per review and $50 per pull request, and you set a monthly limit. (pricing)
Should your team use Gitar or Macroscope for AI code review?
There is no universal winner. Fit depends on your stack, how much of the loop you want automated, and how you budget.
Macroscope fits
GitHub-only teams that want a local CLI review loop before the pull request, prefer paying by usage with no seats, and want custom checks that appear as their own required GitHub checks.
Gitar fits
Teams that run GitLab, Azure DevOps or Bitbucket (alone or alongside GitHub), need CI failure diagnosis across several CI systems, want fixes iterated against CI under rules written in plain language, need merge policy by severity, or review across many repositories (Enterprise).
Either fits
Teams that mainly want accurate inline findings on GitHub. Decide by testing.
Trusted by teams that value a high signal to noise ratio
Gitar has dramatically shortened our time to merge in mobile CI by quickly identifying CI failures and providing insightful AI-powered remediations. Our engineers love taking action directly on their MRs.
What stood out about Gitar right away was how little noise it adds to GitHub. It doesn't clutter pull requests with generic bot comments — its feedback is accurate, relevant, and worth acting on.
Gitar provides top-tier code reviews for our team of 130+ engineers across 1,100+ repos. I feel confident in the merged code thanks to its comprehensive analysis, and the team goes the extra mile.
Gitar is the newest hire for our eng team! It gains context quickly, provides insightful feedback, and caught breaking bugs within its first week. I'd highly recommend it to any team leveling up code reviews.
We haven't found a single invalid comment on our PRs. The quality is remarkably consistent — every suggestion is grounded in the actual code context, not a generic pattern match.
How do Gitar and Macroscope differ?
Both review pull requests with AI and generate fixes. Gitar supports GitHub, GitLab, Azure DevOps and Bitbucket, diagnoses CI failures across several CI systems, and enforces merge policy by severity. Macroscope is GitHub only, with a local CLI, Check Run Agents and usage-based pricing.
Can both fix code and validate against CI?
Yes. Gitar pushes fixes (auto-apply on Pro and Enterprise) and re-analyzes new CI failures using earlier attempts, stopping after three consecutive Gitar commits. Macroscope's Fix it for me opens a fix pull request and validates it against your GitHub Actions results. In both cases a green build is evidence, not proof of production safety.
Which code hosts and CI systems are supported?
Gitar supports GitHub, GitLab, Azure DevOps and Bitbucket (AWS CodeCommit in preview), and reads GitHub Actions, GitLab Pipelines, Bitbucket Pipelines and Azure DevOps Pipelines with no extra setup, plus Jenkins, CircleCI, Buildkite, TeamCity, Harness, Bitrise and Concourse with a credential. Macroscope supports GitHub only, with GitHub Actions documented and other CI systems not confirmed.
Can they approve or block merges?
Gitar can block a merge by severity, auto-approve after a clean review and auto-merge on Pro and above, with enforcement that depends on the code host. Macroscope can auto-approve low-risk pull requests, and its Check Run Agents can fail a check you require in branch protection. Its docs state Approvability alone is not a fail-closed gate.
How does pricing scale with usage?
On Gitar's self-serve plans, cost scales with seats (Core $20 and Pro $40 per user per month). Gitar Enterprise is priced per pull request. Macroscope scales with the volume of code reviewed ($0.05 per KB of diff, 10 KB minimum, plus Agent credits for fixes and custom checks). Model both against your pull request volume and typical diff size.
