Your review bill shouldn't punish you for shipping. Ours doesn't.
CodeRabbit charges per seat, then meters you with hourly rate limits that tighten as you ship more, usage credits, per-minute agent billing, and security as a separate add-on. Optibot is flat-rate, with security and engineering metrics in the Pro seat.
Three ways usage-based pricing gets expensive
This isn't about CodeRabbit being a bad reviewer. It is about a pricing structure with three separate meters running at once. All three figures below are from CodeRabbit's published pricing.
Per-developer rate limits
Pro allows 5 reviews per developer per hour (10 on Pro Plus, 12 on Enterprise). A separate fair-usage policy tightens that further for heavy users, stepping Pro down to 1 sequential review per hour once a developer passes 60 reviews in 7 days.
Usage credit add-on
Credits are $1.00 each and cover $0.25 per reviewed file. They apply to reviews that exceed a plan limit, so a 200-file refactor that Pro would otherwise skip costs about $50 to review on demand.
Per-minute agent billing
CodeRabbit's fixing agent is billed by runtime. There is no flat ceiling, so a heavy month of agent runs has no predictable upper bound.
Where CodeRabbit stops reviewing
CodeRabbit counts the files changed in a pull request, after path filters, against a per-review limit: 150 on Pro, 300 on Pro+ and Enterprise. Most everyday PRs sit well under it. Refactors, migrations, and monorepo-wide renames do not. Drag the slider to see what happens as a PR grows.
Cost of one review as the pull request grows
Changed files in the PR, counted after path filters. Hover or tap the chart.
CodeRabbit Pro includes 150 changed files per review (Pro+ and Enterprise: 300), counted after path filters. Above the limit the automatic review is skipped; on GitHub the usage-based add-on runs it at $0.25 / file. GitLab and Bitbucket have no pay-to-review option. Most everyday PRs sit well under 150 files: this is the shape of a refactor, migration, or monorepo-wide rename.
What 100 reviews actually cost
Now scale it to a month. Optibot is flat by plan; CodeRabbit is a seat plus usage credits that pile up review after review. Set your monthly review volume and see where each lands per user.
At 100 reviews / user / month — recommended Optibot plan:
Optibot Pro
Optibot Pro
$49/user/mo
CodeRabbit (est.)
~$64/user/mo
You save $15/mo per user with Optibot
CodeRabbit = $24 Pro seat + $40 security add-on, matching the security agent included in this Optibot tier. At 100 reviews/user/month (~23/week), fair usage allows a Pro developer 5 review(s) per hour. CodeRabbit has no engineering metrics at any tier.
Rates reflect CodeRabbit's published pricing and fair-usage policy, which is hourly rather than monthly. Verify current pricing on CodeRabbit's site.

- Reddit: Reviewers report wild cost variance: some reviews cost a quarter, others twenty-five dollars, which they say makes a monthly bill impossible to budget. Read on Reddit
- Reddit: Threads describe an undocumented "fair usage" threshold and conflicting answers from support about where it actually sits. Read on Reddit
- Trustpilot: A reviewer reports being charged after a confirmed cancellation, with support going silent afterward. Read on Trustpilot
- Trustpilot: Another describes an "Organisation Not found" error that blocked onboarding for two weeks. Read on Trustpilot

Where CodeRabbit is still the right call
No tool wins on every axis. Two cases where CodeRabbit is the better choice today.
A genuinely generous free OSS tier
If your work is primarily open source, CodeRabbit's free tier for public repositories is one of the most generous in the category. Optibot does not offer a free open-source tier, so for OSS-only work CodeRabbit is the better fit.
Bitbucket & Azure DevOps coverage
CodeRabbit supports Bitbucket and Azure DevOps today. Optibot covers GitHub and GitLab (cloud and self-hosted), with Bitbucket and Azure DevOps in development. If you are on those platforms now, CodeRabbit has you covered out of the box.

Optibot vs CodeRabbit Pricing — Common Questions
Is CodeRabbit or Optibot cheaper?
It depends on how much your team ships. CodeRabbit starts lower per seat ($24/user/mo on Pro, annual), but the seat is only part of the bill: security is a $40/user/mo add-on, the fixing agent is $0.50 per minute, and credits at $0.25 per reviewed file are what let a throttled developer keep reviewing without waiting. Optibot is flat: Plus is $29/user/mo and Pro is $49/user/mo (annual), with the security agent and engineering metrics in the Pro seat and no usage surcharges. Compare the bundle you actually need rather than the headline seat price.
Why does usage-based pricing get expensive for fast-moving teams?
CodeRabbit meters usage three ways. First, a per-developer review rate limit of 5 reviews per hour on Pro (10 on Pro Plus, 12 on Enterprise), which a fair-usage policy tightens further once a developer passes the 95th percentile of recent usage, stepping Pro down to 1 sequential review per hour at 60 or more reviews in 7 days. Second, a usage-credit add-on at $1.00 per credit covering $0.25 per reviewed file, which is how a throttled developer keeps reviewing without waiting for the window to reset. Third, a fixing agent billed at $0.50 per minute. The throttle does not raise your invoice on its own, but it does mean throughput falls exactly when your team is shipping hardest unless you buy credits.
Does Optibot have a per-PR or per-file charge?
No. Optibot is flat-rate per user. A review costs the same whether it touches one file or one hundred. Each plan includes a monthly deep-review allowance (50 on Plus, 100 on Pro, up to 350 on Max). If you reach the monthly allowance, deep reviews pause until the next billing cycle or you can upgrade your plan to restore them immediately.
How accurate are the cost figures on this page?
All hard pricing claims about CodeRabbit (seat prices, the 5/10/12 per-hour rate limits, the fair-usage ladder, the usage-credit add-on, and the $0.50/agent-minute rate) come from CodeRabbit's published pricing and documentation. The $0.25 per reviewed file rate and the $1.00 per credit price are also published, in CodeRabbit's usage-based add-on documentation. Note that the rate limits are hourly rather than monthly, and that credits are optional: a throttled developer can wait for the rolling window to reset instead of buying them. Verify current pricing on CodeRabbit's site before making a decision.
