10 Best AI Code Review Tools of 2026

CodeRabbit ranks first because it covers the most ground for a team adding AI review to pull requests. It installs on GitHub, GitLab, Azure DevOps and Bitbucket, posts a plain language summary and walkthrough on each PR, and reviews the same changes earlier in the IDE, the CLI and inside coding-agent loops. The Essentials plan costs $24 per developer per month billed annually, or $30 monthly, and already includes chat, learnings from prior PRs, pre-merge checks, slop detection for low-quality AI-generated PRs and one-click fixes. Team at $48 adds unit test generation, finishing touches, post-merge actions and a prioritized PR queue, and Advanced at $72 adds blast radius and continuous security monitoring. Essentials allows five PR reviews per developer each hour, with more available on consumption and a budget cap. Public repositories get free reviews forever, which makes it easy to try on an open source project first.

GitHub Copilot code review ranks second because it is the cheapest way for a GitHub team to get AI review on pull requests, and it needs no separate app. Pull request reviews on github.com and file diff reviews in editors are included from Copilot Pro at $10 per user per month, alongside unlimited completions, agent mode and cloud agents. GitHub's docs list support on github.com, GitHub CLI, GitHub Mobile, VS Code, Visual Studio, Xcode and JetBrains IDEs, with Azure DevOps in public preview. Admins can turn on automatic review so Copilot reviews every pull request, and an organization policy lets developers without a Copilot license request a review. The trade-off is metering: code review draws on GitHub AI credits, and Pro includes $15 of them a month, so busy reviewers may need Pro+ at $39. It also lacks the cross-host coverage and dedicated triage features of the specialist tools higher on this list.

Greptile ranks third on the strength of its context and its pricing model. It connects to a repository, builds a graph of every function, class and dependency, and uses that graph to judge how a pull request affects the rest of the system. Its docs list GitHub Cloud and Enterprise Server, GitLab Cloud and Self-Managed, Bitbucket Cloud and Data Center, Gitea and Cursor Origin in beta. Pricing is unusual: Starter is free for one active developer with 50 credits a month, and Pro has no seat fees at all, charging $1 per credit shared across the organization. A base review uses 1 credit, a Plus review 3 and an Apex review 10, so a team chooses review depth per PR. Pro adds learning and custom context, a knowledge base, MCP, cross-repo context, analytics and Jira, Linear and Notion integrations. The catch is predictability: busy repositories running deep reviews will cost more than a flat seat.

Qodo ranks fourth because it goes furthest on governance for organizations with many repositories. Its multi-agent review enforces organizational standards on every pull request, its rules system turns PR history into standards, and its cross-repo software map flags changes that would break downstream services. Docs list installs for GitHub, GitLab, Bitbucket and Azure DevOps, with Gerrit on Enterprise. Pro Team pricing is credit-based: packs start at $30 a month for 2,000 credits, which Qodo estimates at about 14 reviews, and larger packs of 4,000 and 16,000 credits cover roughly 29 and 114 reviews. Credits cost $0.015 each, are pooled across the team and continue into overage at the same rate up to a cap you set. There are no limits on repositories, users or reviews. The downside is cost visibility: the entry pack is small, credits expire monthly, and there is no permanent free tier after the 14-day trial.

Sourcery ranks fifth as the best low-cost reviewer for teams on GitHub or GitLab. Pro costs $12 per developer per month billed annually, or $15 monthly, and adds AI reviews on private repositories, higher review limits and Jira integration on top of the free Open Source plan. Every plan includes PR summaries and diagrams, one-click fixes, custom review rules, auto-approval for low-risk PRs and security checks on every pull request. Team at $24 adds codebase security with nightly scans of 50 repositories, an issues dashboard and team analytics. Sourcery reviews merge requests on GitLab.com and self-managed GitLab on every plan, while GitHub Enterprise Server and self-hosting sit on Enterprise. It says it keeps no copy of your code after a review and does not train models on it. The limits are platform reach, with no Bitbucket or Azure DevOps listed, and a narrower feature set than CodeRabbit or Qodo.

Graphite ranks sixth because AI review is one part of a broader pull request workflow rather than a standalone bot. It is built around stacked PRs, with a CLI, a VS Code extension and MCP, an inbox for pull requests, and on paid plans a merge queue, insights and automations. AI reviews post suggested fixes and CI summaries, and Graphite Chat lets reviewers take suggestions in one click inside GitHub. The free Hobby plan covers personal account repositories with limited AI reviews. Starter costs $20 per user per month billed annually and adds organization repositories, Slack notifications and team insights, but AI reviews and Chat stay limited. Team at $40 is the plan that unlocks unlimited AI reviews, review customization, automations and the merge queue. Graphite only works with GitHub, with GitHub Enterprise Server support on Enterprise, so teams on other hosts cannot use it.

Bito ranks seventh as a low-cost reviewer with wide Git and editor coverage. The Team plan costs $12 per seat per month billed annually, or $15 monthly, and covers AI code reviews in Git, the IDE and the CLI, codebase-aware feedback, one-click fixes and review analytics. It works with GitHub, GitLab and Bitbucket and with VS Code, JetBrains IDEs, Cursor and Windsurf. Professional at $20 billed annually adds custom review guidelines, learning from feedback, Jira, Confluence and Google Docs context, and reviews in CI/CD pipelines, plus a self-hosted option for $5 per seat a month. Both plans include 5K reviewed lines per seat each month and charge $5 per 1K lines after that, so very large PRs can push the bill above the headline price. Bito also sells context engine and model routing products, but those are separate from the review seats.

Codacy ranks ninth because AI review is part of a wider code quality and security platform rather than its whole focus. The Team plan starts at $18 per developer per month billed yearly, or $21 monthly, and adds GitHub, Bitbucket and GitLab integration, cloud-hosted quality and security scans, up to 100 private repositories with unlimited lines of code, the AI Reviewer with merge gates for pull requests, shared coding standards across 49 languages, coverage reports and malicious package detection. The free Developer plan gives local analysis through agent skills, a CLI and IDE plugins for VS Code, JetBrains and Cursor, with handoff to coding agents for fixes, but it does not review pull requests. Team is designed for up to 30 developers, and larger organizations move to the custom Business plan for unlimited projects, DAST and SSO. Pick Codacy if you also need SAST, SCA and coverage gates, not only AI comments.

Cursor Bugbot ranks eighth because it is strong inside one workflow but narrow outside it. When enabled, it reviews new GitHub pull requests in the background, comments on likely bugs and passes fixes to the Cursor editor or a cloud agent. Bugbot Rules let teams define coding standards and project guidelines, and Cursor says it uses a mix of frontier and in-house models, with more than half of the bugs it finds fixed by engineers. There is no separate Bugbot subscription: on individual plans reviews draw on the plan's included usage first, and on Teams plans every review bills from on-demand usage, with Cursor quoting an average of $1.00 to $1.50 a review. The cheapest plan that includes AI code reviews via Bugbot is Premium at $30 a month, since Free and Plus leave it out. It suits Cursor shops on GitHub, but teams on other hosts or other editors get less from it.

CodeAnt AI ranks tenth mainly because its review price could not be confirmed in USD on the pricing page when we checked, which pulls its value score down. On features it is competitive: the Premium plan lists unlimited AI code reviews, PR summaries and chat, custom review prompts, org-wide quality gates, CI/CD integrations, review dashboards, static analysis and SAST on pull requests, and PR blocking for leaked secrets and critical security issues. Its docs cover setup for GitHub, GitHub Enterprise, Bitbucket, Bitbucket Data Center, GitLab including self-hosted, and Azure DevOps, so it reaches more hosts than most tools here. Jira and Azure Boards integrations come on Premium, while on-prem or VPC deployment, SSO, SAML and SCIM need Enterprise. CodeAnt also sells AI pentesting, code security, code quality and developer metrics products, so confirm which bundle a quote covers.
