The formula
Every review is billed based on its actual cost:
LLM cost — determined by the number of tokens processed. Larger diffs consume more tokens and cost more. Smaller PRs cost less.
Platform fee — covers compute, storage, GitHub integration, the multi-agent pipeline, dashboard, and ongoing development. Scales with review size.
| Diff size | LLM cost | Platform fee | You pay |
|---|---|---|---|
| Small (~100 lines) | $0.030 | $0.017 | $0.047 |
| Medium (~400 lines) | $0.080 | $0.037 | $0.117 |
| Large (~1,000 lines) | $0.190 | $0.081 | $0.271 |
Costs shown using Claude Sonnet on Amazon Bedrock at current pricing. Your actual cost depends on diff size, agent count, and prompt configuration.
What affects your cost?
Diff size
The biggest factor. A 50-line fix costs a fraction of a 1,000-line feature PR.
Number of agents
MergeWatch runs multiple specialist agents per review. More agents = more thorough review = more tokens.
Agent prompt configuration
Agent prompts are customizable. More detailed instructions produce more thorough (and slightly more expensive) reviews.
Output length
Longer, more detailed review comments cost more in output tokens. Output tokens are 5x more expensive than input.
Free Tier
Your first 5 reviews are completely free — no credit card required. This is a one-time evaluation period, not a monthly allowance.
Free reviews don’t reset each month. They’re designed to let you see real value on real PRs before committing anything.
Prepaid Credits
Top up when you want, in amounts that make sense for your team:
Optional auto-reload when your balance drops below a threshold you set. Credits never expire. No subscription. No minimum spend.
What will I actually pay?
First 5 reviews always free. Estimate uses average review cost — actual cost varies by diff size.
How does this compare?
Per-seat tools charge the same whether your team merges 5 PRs or 500 that month. MergeWatch charges only for reviews that actually happen.
| 50 PRs/mo | 200 PRs/mo | 500 PRs/mo | |
|---|---|---|---|
| Per-seat tool (5 devs) | $120/mo | $120/mo | $120/mo |
| Per-seat tool (20 devs) | $480/mo | $480/mo | $480/mo |
| MergeWatch | ~$5 | ~$23 | ~$58 |
Per-seat pricing based on typical $24/dev/month plans. MergeWatch estimates use average review cost of ~$0.12/review based on Claude Sonnet pricing.
A transparent look at the token math
Using Claude Sonnet on Amazon Bedrock at current pricing ($3.00 / 1M input tokens, $15.00 / 1M output tokens):
Each agent receives the full diff as input
Input tokens scale with diff size
Output tokens are 5x more expensive than input
Detailed review comments are the biggest cost driver
6 agents per review (default pipeline)
Each agent call adds input + output tokens
Rather than showing fixed prices that may not reflect your actual usage, we show the formula and let you estimate based on your team’s real PR volume.
