Sourcery reviews your pull request and suggests fixes that a developer commits. The Gitar code verification agent reviews the pull request, diagnoses CI failures, and iterates on fixes until your pipeline passes. If you are weighing a Sourcery alternative, the deciding question is who closes the loop after the review comment lands.
Based on documented capabilities, September 2026.
Gitar is an AI code verification agent that reviews every pull request for logic, intent, security, bugs, and edge cases. It monitors CI, separates real failures from flaky and infrastructure noise, and pushes fixes, looping until the build passes or no further progress is possible. Language-agnostic, it runs on GitHub, GitLab, Azure DevOps, and Bitbucket, including self-managed versions. Teams define rules in plain language, with optional auto-approve, merge blocking, and auto-merge. Features include Risk Triage, Knowledge (Enterprise), Functional Validation against linked issues, and Cross-Repo and Cross-PR Analysis. Built for engineering managers, tech leads, platform engineering, and AppSec teams.
Sourcery is AI code review and security scanning for GitHub and GitLab. Every pull request receives a summary, a reviewer's guide with diagrams, inline comments, and (on GitHub) a status check. Where Sourcery can propose a fix, it posts a suggested change that a developer commits with one click. Teams can write review rules in plain language, scope them by path, and let Sourcery auto-approve low-risk pull requests. Sourcery also offers IDE reviews and a security scanning dashboard for secrets, SAST, infrastructure as code, and dependencies. Sourcery fits teams standardized on GitHub or GitLab that want fast, developer-driven review at a low per-seat price.

Sourcery does have a lower entry price. The rest of this page explains what that price buys, and what it leaves with your developers.
Both tools keep people in control. Sourcery leaves the commit with the developer, so oversight is built into the workflow by design. Gitar automates more steps, so it makes the controls explicit: auto-approve, merge blocking, and auto-merge are opt-in, governed by rules you write in plain language and by your branch protection. Developers can ask questions in the PR thread and direct Gitar.
Sourcery offers a required status check on GitHub and optional auto-approval of low-risk pull requests. Gitar adds merge blocking under your rules, Risk Triage that classifies the consequence of a change and feeds approval and merge criteria, and, on Enterprise, Functional Validation that re-judges the PR against its linked issue on every push. Merge controls vary by code host, so check Gitar's platform support matrix for your setup.
Sourcery documents repository-wide security scanning for secrets, SAST, infrastructure as code, and dependencies, with a findings dashboard on the Team plan. If you want one bundled scanner at a low per-seat price, that is a real strength. On Enterprise, Agentic Security also reviews changes to agent instructions and supporting scripts. For deterministic security analysis, pair it with SonarQube.
An AI model that reviews AI-generated code shares blind spots with the model that wrote it. Verification needs a layer built on a different method. SonarQube is that independent verification layer: deterministic, auditable analysis of syntax, data flow, control flow, architecture, and dependencies, enforced through quality profiles and quality gates. Gitar adds the agentic layer on top: it reviews logic and intent and drives fixes to a passing build. SonarQube sets the standard, and Gitar enforces it at merge speed.
Both vendors state that they do not train on your code. Gitar processes code in ephemeral, isolated containers under zero data retention agreements with its AI providers, and encrypts it in transit and at rest. Sourcery keeps no copy of your code after a review and is SOC 2 Type II. On Enterprise plans, both support bring your own model, and Sourcery also offers self-hosting, including GitHub Enterprise Server.
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 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.
Gitar fixes them. Fixes on request are available on every plan, and the Pro plan adds auto-apply, a fix loop that iterates until CI passes or no further progress is possible. Sourcery's public documentation describes one-click suggested fixes that a developer commits.
Gitar monitors your pipelines, identifies the root cause, separates real breakage from flaky tests and infrastructure noise, and can push a fix. Gitar reads GitHub Actions, GitLab Pipelines, Bitbucket Pipelines, and Azure DevOps Pipelines out of the box, and connects to Jenkins, CircleCI, Buildkite, TeamCity, Harness, and Bitrise. It can also retry CI jobs whose failures are unrelated to the PR. Sourcery's public documentation describes a status check but does not describe CI failure diagnosis.
Gitar supports GitHub, GitLab, Azure DevOps, and Bitbucket, including self-managed GitLab, Azure DevOps Server, and Bitbucket Data Center. Some merge controls vary by host. Sourcery supports GitHub and GitLab, plus GitHub Enterprise Server and self-managed GitLab.
Sourcery costs less per seat: Pro is $12 and Team is $24 per user per month billed annually. Gitar Core is $20 and Pro is $40 per user per month billed annually, with unlimited repositories and up to 50 users. Both offer a 14-day free trial with no credit card and free plans for open source. Gitar Enterprise is one flat fee per PR, with unlimited iterations to reach green, so cost does not grow with retries. Sourcery Enterprise is custom. To compare total cost, weigh the license price against the developer time your team spends applying fixes and rerunning CI.
Yes. Gitar complements SonarQube. SonarQube provides deterministic, auditable analysis, and Gitar reviews logic and intent and drives fixes to a passing build. Gitar is available standalone or with SonarQube.
Sourcery combines AI review with a security scanner, so some buyers compare it with SonarQube. SonarQube is the independent verification layer for code quality and security, with deterministic analysis and quality gates. AI reviewers such as Gitar and Sourcery work best alongside it.
Gitar iterates on a fix, taking previous attempts into account, until CI passes or no further progress is possible, then posts a summary of what it tried if it cannot finish. On Enterprise, iterations are unlimited under one flat fee per PR, with no per-author review allowances. Core and Pro follow a usage policy that can pause automatic re-reviews after pushes when an organization uses its processing headroom, which scales with seats. Sourcery measures usage in diff characters per pull request and per rolling seven days, skips a review when a limit is reached, and caps automatic re-reviews at five per pull request.
