by GitKraken — 47M+ installs — Git history and blame
The most installed Git extension for VS Code. Shows blame annotations, file history, commit graphs, and branch comparisons. The Pro tier ($9.99/mo) adds visual commit graph and worktree support. Does not do AI code review or PR management — it's a Git visibility tool.
Pros
Cons
Best for: Understanding code history and authorship during manual review.
by GitHub (Microsoft) — 20M+ installs — PR management
The official GitHub extension for managing pull requests inside VS Code. Create, review, comment, approve, and merge PRs without leaving your editor. Shows inline diff comments and review threads. GitHub-only — won't work with GitLab or Bitbucket.
Pros
Cons
Best for: GitHub users who want to review PRs without opening a browser.
by Git AutoReview — Growing installs — AI code review
AI-powered code review that runs inside VS Code. Analyzes PR diffs using Claude, Gemini, or GPT (your choice via BYOK). Reviews come back as inline comments you approve or reject before they're published. 20+ built-in security rules catch SQL injection, XSS, hardcoded secrets. The only VS Code extension that supports Bitbucket Server and Data Center.
Pros
Cons
Best for: Teams that want AI review with human approval, Bitbucket support, or flat-rate pricing.
by Atlassian — 2M+ installs — Bitbucket PR + Jira
Atlassian's official VS Code extension for Bitbucket and Jira. Create, review, approve, and merge Bitbucket PRs directly in VS Code. Shows inline diff comments, pipeline status, and linked Jira issues. Bitbucket-only — won't work with GitHub or GitLab.
Pros
Cons
Best for: Bitbucket + Jira teams who want PR management in VS Code.
by GitLab — 3M+ installs — MR management
GitLab's official VS Code extension. Browse merge requests, view CI/CD pipeline status, create snippets, and manage issues. Supports both GitLab Cloud and Self-Managed instances. GitLab-only — won't work with GitHub or Bitbucket.
Pros
Cons
Best for: GitLab users who want MR management in VS Code.
by GitHub (Microsoft) — 71M+ installs — AI assistant with code review
Copilot is primarily a code completion tool, but GitHub added code review features in 2025. Copilot can review PR diffs and leave comments on GitHub. The review is diff-only (misses cross-file and architectural issues) and auto-publishes without human approval. Requires a Copilot subscription ($19-39/user/mo). GitHub-only.
Pros
Cons
Best for: Solo developers already paying for Copilot who want basic PR feedback.
by Sourcegraph — 500K+ installs — AI assistant
Cody is Sourcegraph's AI coding assistant. It uses Claude and has deep codebase understanding via Sourcegraph's code intelligence. Strong at explaining code and answering questions about large codebases. Not a dedicated code review tool — it's more of an AI pair programmer.
Pros
Cons
Best for: Teams using Sourcegraph who want AI-assisted code understanding.
GitHub PRs extension for PR management + Git AutoReview for AI-powered review with human approval. Copilot works too but auto-publishes and costs more per user.
