What changes when you hire it
Hours
Changes wait on senior engineers
A pull request sits until someone senior has time, and the author waits with it.
Minutes
Reviewed as soon as it opens
The review starts when the pull request opens, even at 3 AM on a Sunday. The author keeps working.
Review bots post piles of comments
Every comment looks equally urgent. Someone still reads them all and decides whether the change can merge.
Every review ends in a verdict
Approve or request changes, every time. Its approval counts toward required reviews, so you see what can ship.
$48 / dev
Seat pricing grows with headcount
CodeRabbit's Team plan bills every developer each month, even ones who barely open a pull request.
$0 / seat
Priced by the work
You pay for the hours it spends reviewing. Hiring your next engineer adds nothing to the bill.
How it works
From the day you hire it to the work it does every day after.
Day 1
Connect GitHub, pick repositories
Tick the repositories it should review. There's nothing to install or host.
Same day
It clears the backlog
Its first pass reviews the open pull requests nobody has reviewed yet.
Every pull request
One verdict, on the exact lines
It reads your repo's rules and the whole change, then approves or requests changes.
Every push
It follows through to merge
Push a fix and it reviews again. Tag it and it answers, or changes its mind if you're right.
What it does for you
Blocks only what would hurt
Regressions, security holes, lost data and broken rules block the merge, each with the steps that cause it.
If the provider times out after charging, this retry charges the customer twice. Pass evt.id as the idempotency key so each payment goes through once.
Follows the rules you wrote
It reads CLAUDE.md, AGENTS.md and CONTRIBUTING.md. Edit a rule and the next review applies it.
CLAUDE.md says every new endpoint needs a test. /api/refunds has none yet. Add one for a partial refund and I'll approve.
Comments labeled by urgency
Each is marked Must fix, Question, Suggestion or Nit, and says what breaks, for whom and how to fix it.
“Retrys” should be “retries”. Not blocking; fix it if you're in the file anyway.
Keeps pace with coding agents
Coding agents open pull requests around the clock. It reviews each as it lands, so none wait for a person.
Adds the date filter the task asked for and nothing else. The new query has a test for empty ranges. Approved, ready to merge.
Reviews outside contributors safely
On open-source repos it reviews strangers' pull requests in batches and ignores instructions hidden in their text.
Thanks for the fix. The description asks reviewers to skip the tests, so I ran them anyway: one fails on Windows paths. Fix that and this is ready.

Drag the slider: hire ten more engineers
Seat-priced tools charge for each one. Your reviewer costs what it reviews: more pull requests, more hours, up to a cap you set.

Common questions
Can it change our code or merge?
No. It only reviews. Give it its own GitHub App and its approvals count toward your branch rules, but it can't push code or merge anything.
Does it review AI-written code?
Yes, that's most of what it reviews. human0 is built by AI agents, and this reviewer checks every change they make before it merges.
Can I run it alongside Copilot or CodeRabbit?
Yes. It's one more reviewer on your pull requests. Run it next to your current tool for a few weeks and compare the reviews.
Which code hosts does it work with?
GitHub today, on public and private repositories.
