FreemiumFrom $24/dev/moWorks with Claude Code

Quick take

A second pair of eyes on every code change. It summarises the change, flags bugs and suggests one-click fixes right in GitHub or GitLab.
Free for public repos forever. Private repos get free summaries and a few reviews an hour in the editor and terminal, but proper pull request reviews start at $24 a developer a month billed yearly.
Plans say unlimited reviews, but each developer gets 5 to 12 an hour. Users who push lots of small changes report being cut to one an hour.
It catches real bugs, including in AI-written code, but it rarely says anything is fine and some comments are nitpicks.
Raised $143 million at a $1.5 billion valuation in August 2026, so it isn't going anywhere soon.

What is CodeRabbit?

CodeRabbit reviews code for you. Connect it to GitHub, GitLab, Bitbucket or Azure DevOps, and every time someone opens a pull request (a proposed change), it writes a plain-English summary, then leaves comments on the lines it thinks are wrong, risky or messy. You can reply to it like a colleague, and it learns your preferences over time.

It's most useful when an AI agent is writing a lot of your code. Claude Code, Cursor and Codex can produce changes faster than anyone can read them, and CodeRabbit gives each one a careful second look before it goes live. GitHub Copilot and Cursor have their own review features, but CodeRabbit works with any agent, goes deeper and does nothing else.

The catch is limits. Plans are sold as unlimited, but each developer gets a few reviews per hour, and heavy users report being throttled to one an hour under the fair-use policy. It can also be chatty, with nitpicks mixed in among the real bugs.

Who's using it, and who it's for

Software teams
Open-source maintainers

Best use cases

1
Safety net for AI-written code
Let Claude Code or Cursor open the pull request, have CodeRabbit review it, then paste its comments back to the agent to fix.
2
Review without a senior developer
A small team or a solo founder gets a thorough review on every change without hiring someone to do it.
3
Understand what changed
Read its plain-English summary to see what a contractor or agent actually did before you approve it.
4
Keep standards consistent
Teach it your team's rules once and it checks every change against them.

How it fits your tech stack

It sits on top of GitHub, GitLab, Bitbucket or Azure DevOps and doesn't replace your editor or coding agent. It pairs naturally with Claude Code, Cursor or Codex, and connects to Jira, Linear and Slack.
