For ten developers running roughly 100 pull request reviews each a month, CodeRabbit Pro costs $240, GitHub Copilot Business costs $190 plus a variable Actions bill, and Greptile Pro costs about $800 because it includes 50 reviews a seat and charges $1 for every review after that. The prices are close only if you read the headline numbers. The three vendors bound the same product three completely different ways, and that mechanism, not the sticker, is what decides your invoice.
Every figure below was read from each vendor's own pricing page and documentation in August 2026. All three changed something material in the first half of the year, so most of what is written about this comparison is out of date, including the parts that quote a Copilot "premium request" allowance that no longer exists under that name.
The three price cards, side by side
Start with what each vendor asks for a seat, and what a seat gets you.
| Vendor | Team plan | Price per developer | Reviews included | Cost of one more review |
|---|---|---|---|---|
| CodeRabbit | Pro | $24 / mo billed annually | No stated monthly cap | No per-review price. Capped at 5 reviews per developer per hour instead. |
| CodeRabbit | Pro Plus | $48 / mo billed annually | No stated monthly cap | Same, at 10 reviews per developer per hour. |
| Greptile | Pro | $30 / seat / mo | 50 credits per seat, 1 credit = 1 standard review | $1.00 per additional credit. |
| GitHub Copilot | Business | $19 / seat / mo | 1,900 AI credits, shared with chat and the coding agent | $0.13, being 13 credits at $0.01. |
| GitHub Copilot | Enterprise | $39 / seat / mo | 3,900 AI credits, same shared pot | $0.13. |
Two things in that table are worth pausing on, because they are the whole article.
The first is that Greptile's overage rate is 7.7 times Copilot's for the same job. Greptile prices one review at a dollar. GitHub prices one review at thirteen cents, because it applies a fixed model multiplier of 13 to a credit worth a cent. Both numbers are published by their respective vendors and neither is disputed. On a team that reviews heavily, that ratio is the single largest number in the comparison and almost nobody puts the two figures next to each other.
The second is that CodeRabbit has no overage rate at all, and that is not an oversight. It caps the rate rather than the budget: five reviews per developer per hour on Pro, ten on Pro Plus, twelve on Enterprise, all subject to a fair usage policy. You cannot spend more than your seat price. You can only be told to wait.
Capping the budget against capping the rate
This is the distinction that decides which of these tools is right for you, and it gets almost no coverage because it is a structural difference rather than a number you can put in a comparison grid.
CodeRabbit and, to a lesser degree, Greptile's included tier put a ceiling on how fast you can consume the product. GitHub puts a ceiling on how much you can consume before you start paying more. The practical consequences run in opposite directions:
- On CodeRabbit, a heavy month costs exactly what a light month costs. Ten seats is $240, whether your team merged forty pull requests or four hundred. The risk you are carrying is a rate limit during a crunch, not a bill.
- On Copilot, a heavy month costs more and you find out afterwards. There is no rate limit to hit, so nothing tells you to slow down. The meter simply runs, and the number that lands on the invoice depends on how the month went.
- On Greptile, both happen. Fifty reviews a seat is a low ceiling for a team that reviews every push, and past it the dollar-a-review rate compounds quickly.
If your finance team wants a fixed number in a budget, CodeRabbit's mechanism is the one that gives it to them. If your engineering team wants to never be throttled mid-incident, Copilot's mechanism is the one that never throttles. Those are genuinely different preferences and neither is wrong.
The team-of-ten arithmetic
Take ten developers, each opening or updating enough pull requests to trigger about 100 reviews a month. That is a normal figure for a team that reviews on every push rather than once per branch.
| Setup | Base cost / mo | Overage | Total / mo | Can you know this in advance? |
|---|---|---|---|---|
| CodeRabbit Pro, 10 seats | $240 | None possible | $240 | Yes, exactly. |
| Greptile Pro, 10 seats | $300 | 50 extra reviews each at $1, so $500 | $800 | Yes, if you can predict review volume. |
| Copilot Business, 10 seats, review only | $190 | None. 100 reviews is inside the 146 a seat's credits buy. | $190 plus Actions | No. See below. |
| Copilot Business, 10 seats, realistic mixed use | $190 | Roughly $35 if half the allowance goes to chat and the agent | ~$225 plus Actions | No. |
The Copilot rows need the caveat spelled out, because it is where most published comparisons quietly cheat. A Business seat's 1,900 AI credits divided by the 13-credit review multiplier gives 146 reviews a month, and 100 fits comfortably inside that. But those same 1,900 credits pay for Copilot chat, the coding agent, and everything else agentic in the seat. Nobody buys a Copilot seat to use it only as a reviewer. Assume half the allowance goes elsewhere and the free review count drops to about 73, which puts a 100-review developer 27 reviews over, or $3.51 each, or $35 across the team.
Then there is the part you cannot put in the table at all. Since June 1, 2026, every Copilot code review on a private repository also consumes GitHub Actions minutes from your plan entitlement, billed at standard rates past your included amount. GitHub has not published how many minutes a review run takes. So the honest bottom line for the Copilot rows is a base you can calculate and a second meter you cannot, which is exactly the position CodeRabbit's flat seat is designed to avoid. We break the credit side down in full on our GitHub Copilot code review page.
What each one is actually best at
Price is the easy half. The harder question is what you lose by picking the cheap one.
GitHub Copilot code review wins on being already there. It is inside a seat most teams have already bought, it takes one branch ruleset to cover every repository in the organization, and it reviews from inside VS Code before a pull request exists. It also carries a hard limit that rules out a common use case: GitHub documents that Copilot always leaves a Comment review, never an Approve or a Request changes, so it cannot count toward a required approval and it will not block a merge. If somebody has sold you an AI reviewer as a way to drop a required human reviewer, that is the sentence to show them.
CodeRabbit is the most feature-dense of the three at the price. Pro includes agentic reviews on pull requests and from the CLI, one-click fixes, pre-merge checks, linter and SAST integration, and Jira and Linear connections. Pro Plus adds multi-repo analysis across ten repositories, unit test generation and merge conflict resolution. It is free forever on public repositories, which is a genuinely generous position for open-source maintainers, and there is a 14-day trial on the paid plans.
Greptile is the one to look at if codebase-wide context is your actual complaint about AI review. Its pitch is understanding the whole repository rather than the diff. The free Starter tier gives one developer 50 credits a month, which is a real way to test that claim before paying. Just go in with the credit maths clear: $30 a seat buys 50 reviews, and the fifty-first costs a dollar.
The question to ask before any of them
Work out what a review is worth to you before you compare what one costs. At the numbers above, a Copilot review is thirteen cents and a Greptile review is a dollar, and both are trivial next to the loaded hourly cost of the senior engineer whose attention the review is meant to save. If you are not sure what that hourly figure is for your team, it is worth pinning down properly, because most of these buying arguments collapse the moment you put a defensible engineering pay band next to the tool spend. Twenty minutes of a staff engineer's review time, once a week, pays for any of these plans several times over.
Which means the real question is not which is cheapest. It is whether an advisory reviewer is the thing your team is short of at all. A reviewer comments on work that already exists. If the bottleneck is that the work does not exist yet, no amount of review tooling touches it, and you are looking for an AI coding agent rather than a reviewer. Plenty of teams need both and should stop trying to make one product do the other job.
Frequently asked questions
How much does CodeRabbit cost per month?
CodeRabbit Pro is $24 per developer per month billed annually, and Pro Plus is $48. Enterprise is quoted. There is a 14-day free trial on the paid plans, and CodeRabbit is free forever on public repositories. Add-ons are priced separately: CodeRabbit Security is $40 per user per month.
Is CodeRabbit cheaper than GitHub Copilot code review?
Per seat, no. CodeRabbit Pro is $24 against Copilot Business at $19, and the Copilot seat also includes chat, completions and the coding agent. CodeRabbit is cheaper in a different sense: its price cannot move. Copilot's can, because reviews meter against a shared credit allowance and against Actions minutes on private repositories.
Does CodeRabbit have a limit on how many reviews I can run?
Not a monthly one. It limits the rate: 5 pull request reviews per developer per hour on Pro, 10 on Pro Plus and 12 on Enterprise, all subject to a fair usage policy. You cannot exceed your seat price by reviewing more, you can only be asked to wait.
How much does Greptile cost per review?
A Greptile Pro seat is $30 a month and includes 50 credits, where one credit is one standard review and a TREX review costs three. Additional credits are $1 each. That makes Greptile's marginal review roughly 7.7 times the cost of a GitHub Copilot code review, which prices at 13 credits of one cent each.
Can any of these tools approve or block a pull request?
GitHub Copilot cannot, by documented design: it leaves Comment reviews only, which do not count toward required approvals and do not block merges. If a hard gate is what you need, a required status check running your tests or your linter is the mechanism that actually stops a merge. Treat every AI reviewer as advice that shortens the human review, not as the gate itself.
Which should a team of ten pick?
If you are already on Copilot Business and your repositories are public, turn code review on today and pay nothing extra. If your repositories are private and you want a number you can budget, CodeRabbit Pro at $240 for ten seats is the only one of the three whose invoice cannot surprise you. Look at Greptile if whole-repository context is the specific thing you are missing, and test it on the free Starter tier before committing, because its included allowance is the tightest of the three.
