6 free alternatives to Gerrit Code Review

Reviewable's free plan covers unlimited reviews for public repositories and personal private repositories, so it gives you a usable hosted review surface without a hard review-count cap. It also includes email support, which can be useful if your team wants a low-friction place to review GitHub pull requests. The main free restriction is the 10MB file upload limit, and the offer is centered on GitHub pull requests rather than a self-hosted Gerrit workflow. If you want a hosted review tool with a simple free entry point and do not need Gerrit's self-managed model, this is a reasonable switch.

• Beats Gerrit Code Review: Hosted GitHub pull-request workflow
• Falls short: No self-hosted, no usage caps
• Who should switch: Switch here if you want a hosted review tool for GitHub and do not want to run your own code review server.

GitGud.io is free for unlimited private repositories and groups, with no repository size limit for code and development content. Its free tier also adds GitLab CI runner access by request, Pages hosting for static sites, a container registry, wiki support, issue boards, snippets, service desk tickets, and direct administrator support. That makes it broader than a pure review tool, especially if you want hosting plus adjacent project features in one place. It falls short of Gerrit on review-specific workflow depth, because the free tier description is about Git hosting and project management rather than a specialized code review system. Choose it if your real need is a free GitLab-style platform, not just review.

• Beats Gerrit Code Review: Broader Git hosting and project features
• Falls short: Less review-specific than Gerrit
• Who should switch: Switch here if you want a free Git hosting platform with CI, pages, registry, and issue tracking alongside code collaboration.

CodeRabbit's free offer is a 14-day free usage of the Pro plan with no credit card required, plus unlimited public and private repositories, PR summarization, and IDE reviews. For teams evaluating an AI-assisted review workflow, that gives you a fast way to try automated review features across repositories without immediate payment friction. Its free access is time-limited, though, so it is not an always-free replacement for Gerrit's unbounded self-hosted option. It also focuses on AI review assistance and pull requests rather than a traditional review server with branch administration and access-control workflows. Pick it if you want to test AI review behaviors before committing.

• Beats Gerrit Code Review: AI review features and IDE support
• Falls short: Only a 14-day free usage window
• Who should switch: Switch here if you want to evaluate AI-assisted reviews and are fine with a short trial instead of permanent free use.

GForge's free on-premise edition includes up to 5 active users, unlimited public projects, unlimited private projects, full functionality, and no time limits. It is a good fit for teams that want a broader DevOps and project management platform rather than a code review tool alone. The free tier is also explicit about not needing a credit card. Compared with Gerrit, the tradeoff is that GForge is capped at 5 active users, so it is much less open-ended for growing teams. It is best when you want a bundled system for repositories, issue tracking, wiki, chat, and CI/CD with a small team.

• Beats Gerrit Code Review: All-in-one DevOps and project management
• Falls short: Capped at 5 active users
• Who should switch: Switch here if you want a self-hostable platform with project tracking and DevOps features, not just code review.

SemanticDiff's free tier is always free for 3 seats and includes public and private repositories, review comments, approve or request-changes actions, GitHub review sync, 14 programming languages, a minimap view, and diff intelligence that hides style changes, detects moved code, and detects refactorings. That makes it useful when reviewers care about understanding code motion and structural change rather than only line-by-line diffs. The free tier is clearly smaller than Gerrit's unbounded model because it is seat-limited and GitHub-centered. Use it if your main pain is reading diffs, especially in a small team that wants richer change visualization.

• Beats Gerrit Code Review: Semantic diffing and change visualization
• Falls short: Only 3 free seats
• Who should switch: Switch here if you want better diff comprehension for a small GitHub-based team.

Mergify's free tier supports up to 5 users on private repositories and includes CI Insights, Test Insights, Merge Queue, Merge Protections, email support, 24/7 Premium Support, Slack Connect Support Channel, Dedicated Customer Success Manager, and on-premise deployment. That gives small teams a surprisingly broad merge-automation stack for free, especially if they care about keeping pull request flow under control. It falls short of Gerrit on being a dedicated review system, since the free offer is centered on GitHub merge automation rather than a general self-hosted review server. Pick it when merge policy and queueing matter more than the review tool itself.

• Beats Gerrit Code Review: Merge automation and queueing
• Falls short: Only 5 users on private repos
• Who should switch: Switch here if your team wants free merge automation around GitHub pull requests rather than a classic code review server.
