What Teams Actually Pay
A 10-developer team on CodeRabbit Essentials pays $240 per month billed annually or $300 billed monthly, regardless of how many PRs they open. On Team, that becomes $480 to $600.
The cost does not scale with PR volume until the team hits the hourly review limit. After that, $0.25 per file adds up.
How Much Does Greptile Cost?
Greptile charges $1 per Base review credit, with no per-seat fees. Each review costs 1, 3, or 10 credits depending on the depth you choose.
Greptile Pricing (November 2026)
| Tier | Credits per Review | Cost per Review |
|---|---|---|
| Starter (free) | 1 active dev, 50 credits/month | Free |
| Base | 1 credit | $1 |
| Plus | 3 credits | $3 |
| Apex | 10 credits | $10 |
Discounts: Free for qualified non-commercial open-source projects. 50% off for pre-Series A startups under $2M revenue.
Source: greptile.com/pricing, checked November 2026.
What Teams Actually Pay
A team doing 200 Base reviews per month pays $200. A team running mostly Plus reviews pays $600. Apex reviews at 10 credits each can add up quickly.
The bill scales with review volume and depth, not with team size.
How Much Does Cursor Bugbot Cost?
Cursor Bugbot is usage-based, averaging $1 to $1.50 per run with no seat fee. Bugbot is billed from Cursor Teams on-demand spend, so the cost rolls into your Cursor subscription.
For teams already on Cursor, Bugbot is a natural addition. For teams not on Cursor, the combined cost of Cursor Teams plus Bugbot usage needs to be factored in.
Usage-Based vs Seat-Based: Which Costs Less?
For a fixed team size, usage-based pricing is cheaper at low to moderate review volumes, while seat-based pricing can be cheaper as review volume rises. Usage costs grow with each review; seat costs stay fixed below hourly limits.
When Usage-Based Is Cheaper
- Low or variable PR volume. Quiet weeks cost less, and teams pay only for the reviews they run.
- Small teams. A 5-developer team with moderate PR volume pays for actual reviews rather than 5 seats.
When Seat-Based Is Cheaper
- High PR volume per developer. More reviews increase usage charges, while seat costs stay fixed below hourly limits.
- Coding agents. One developer with Claude Code or Cursor can ship 2-3x more PRs without adding seats, but those extra reviews increase usage charges.
- Predictable budgeting. Finance teams that want a flat monthly line item prefer seats.
Cost Comparison: 10 Developers, 200 PRs/Month
| Tool | Pricing | Monthly Cost |
|---|---|---|
| Macroscope (Balanced) | $0.05/KB, 76¢ avg | ~$152 |
| Macroscope (Budget) | $0.025/KB, 55¢ avg | ~$110 |
| CodeRabbit Essentials | $24/dev annual | $240 |
| CodeRabbit Team | $48/dev annual | $480 |
| Greptile Base | $1/credit | $200 |
At 200 PRs a month, Macroscope costs 30-55% less than CodeRabbit Essentials and 20-45% less than Greptile Base. At higher volumes, the gap narrows as usage charges accumulate against fixed seat costs.
How to Reduce AI Code Review Costs
The lowest-cost setup is Macroscope in Budget mode with spend controls configured.
1. Choose Budget Mode
Budget mode costs $0.025 per KB, half the Balanced rate. Detection is slightly lower, but the cost savings are meaningful at scale.
2. Set Spend Caps
Configure per-review and per-PR caps to prevent runaway costs from large diffs or force-push loops.
3. Exclude Generated Files
Migrations, lockfiles, and vendor directories inflate diff size without adding review value. Exclude them from the review meter.
4. Use On-Demand Review for Noisy Repos
For repos with heavy generated code or frequent churn, turn off auto-review and trigger reviews manually when needed.
