Your review bill shouldn't punish you for shipping. Ours doesn't.

CodeRabbit charges per seat, then meters you with per-developer rate limits, usage credits, and per-minute agent billing, so the faster your team moves, the more you pay. Optibot is flat-rate: you know the bill before the month starts. Same price whether your team ships 5 PRs or 50.

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 caps each developer at 5 reviews (10 on Pro Plus, 12 on Enterprise). Hit the cap and the next review queues until your limit resets.

Usage credit add-on

Cost scales with the files a review touches, so a one-line change across a shared component can cost far more than a 10,000-line change in a single file.

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.

What one review actually costs

Drag the slider, or pick a preset, to see how a single review's cost changes with the number of files it touches.

Files touched in this PR 24

1 file 200 files

CodeRabbit usage credits $6.00 / review

Optibot flat-rate $0.00 marginal

Included in your flat plan. No per-file or per-minute charge: the same review costs the same whether it touches 1 file or 100.

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

$49/user/mo

vs

CodeRabbit (est.) ~ $380/user/mo

You save $331/mo

Optibot is flat per user. CodeRabbit estimate = $24 Pro seat + usage credits for the 95 reviews past the 5/developer cap, at an illustrative ~$0.25/file × 15 files.

What teams are saying

Reviewer opinion

• Reviewers report wild cost variance: some reviews cost a quarter, others twenty-five dollars, which they say makes a monthly bill impossible to budget.

• Threads describe an undocumented "fair usage" threshold and conflicting answers from support about where it actually sits.

Reviewer opinion

• A reviewer reports being charged after a confirmed cancellation, with support going silent afterward.

• Another describes an "Organisation Not found" error that blocked onboarding for two weeks.

Reviewer opinion

• Reviewers note the terms change frequently.

• Usage add-on pricing is described as vague, with an asterisk hanging off the headline number.

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, 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 its per-seat price is only part of the bill: per-developer rate limits, usage credits to review past the cap, and $0.50 per agent minute all add variable cost on top. Optibot is flat: Plus is $29/user/mo and Pro is $49/user/mo (annual), with no usage surcharges. For teams shipping more than a few PRs per developer per month, Optibot is typically the more predictable and often lower total cost.

Why does usage-based pricing get expensive for fast-moving teams?

CodeRabbit meters usage three ways: a per-developer review rate limit (5 on Pro, 10 on Pro Plus, 12 on Enterprise), a usage-credit add-on that scales with the files a review touches, and a fixing agent billed at $0.50 per minute. The faster your team ships, the more often you hit the cap, top up credits, and run agents, so your bill rises with your velocity.

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 generous monthly deep-review allowance (50 on Plus, 100 on Pro, up to 350 on Max). If you reach the monthly allowance, Optibot falls back to quick reviews rather than charging you more.

How accurate are the cost figures on this page?

All hard pricing claims about CodeRabbit (seat prices, the 5/10/12 per-developer rate limits, the usage-credit add-on, and the $0.50/agent-minute rate) come from CodeRabbit's published pricing. The per-file cost in the interactive calculator is an illustrative model (~$0.25/file reviewed) used to show how usage-based cost scales; it is not an official published per-file rate.
