# CodeRabbit Cost Tuning

## Overview
Optimize CodeRabbit costs through smart tier selection, sampling, and usage monitoring.

## Prerequisites
- Access to CodeRabbit billing dashboard
- Understanding of current usage patterns
- Database for usage tracking (optional)
- Alerting system configured (optional)

## Pricing Tiers

| Tier | Monthly Cost | Included | Overage |
|------|-------------|----------|---------|
| Free | $0 | 1,000 requests | N/A |
| Pro | $99 | 100,000 requests | $0.001/request |
| Enterprise | Custom | Unlimited | Volume discounts |

## Cost Estimation

```typescript
interface UsageEstimate {
  requestsPerMonth: number;
  tier: string;
  estimatedCost: number;
  recommendation?: string;
}

function estimateCodeRabbitCost(requestsPerMonth: number): UsageEstimate {
  if (requestsPerMonth <= 1000) {
    return { requestsPerMonth, tier: 'Free', estimatedCost: 0 };
  }

  if (requestsPerMonth <= 100000) {
    return { requestsPerMonth, tier: 'Pro', estimatedCost: 99 };
  }

  const proOverage = (requestsPerMonth - 100000) * 0.001;
  const proCost = 99 + proOverage;

  return {
    requestsPerMonth,
    tier: 'Pro (with overage)',
    estimatedCost: proCost,
    recommendation: proCost > 500
      ? 'Consider Enterprise tier for volume discounts'
      : undefined,
  };
}
```

## Usage Monitoring

```typescript
class CodeRabbitUsageMonitor {
  private requestCount = 0;
  private bytesTransferred = 0;
  private alertThreshold: number;

  constructor(monthlyBudget: number) {
    this.alertThreshold = monthlyBudget * 0.8; // 80% warning
  }

  track(request: { bytes: number }) {
    this.requestCount++;
    this.bytesTransferred += request.bytes;

    if (this.estimatedCost() > this.alertThreshold) {
      this.sendAlert('Approaching CodeRabbit budget limit');
    }
  }

  estimatedCost(): number {
    return estimateCodeRabbitCost(this.requestCount).estimatedCost;
  }

  private sendAlert(message: string) {
    // Send to Slack, email, PagerDuty, etc.
  }
