Cost Optimization Strategies

1. API Cost Reduction

Techniques:

  • Caching: Cache AI responses for identical queries (30-day TTL)
  • Batch Processing: Group similar requests (e.g., weekly topic suggestions)
  • Haiku for Simple Tasks: Use Claude Haiku for media triage (5x cheaper)
  • Rate Limiting: Cap AI requests per user/day
  • Human Overrides: Allow admins to skip AI for trivial cases

Savings: 30-50% reduction in API costs

2. Hosting Cost Reduction

Techniques:

  • Start Small: Begin with VPS Value, upgrade as needed
  • Annual Billing: OVHCloud offers ~20% discount for annual payment
  • Resource Optimization: Optimize database queries, enable caching
  • Self-Host Everything: Analytics, error tracking, monitoring (no SaaS fees)
  • Cloudflare Free Tier: CDN + DDoS protection at no cost

Savings: 20-30% reduction in hosting costs

3. Bandwidth Optimization

Techniques:

  • Image Optimization: WebP format, lazy loading
  • Compression: Gzip/Brotli for all text assets
  • CDN: Offload static assets to Cloudflare
  • Minimize Dependencies: No unnecessary JavaScript libraries

Savings: Avoid bandwidth overage fees

Budget Recommendations

  • Month 3: $150 (soft launch)

Contingency Planning

Recommended Buffer: +20% ($110 USD / ~$180 NZD)

// Example usage:
const monthlyBudget = calculateMonthlyCost({
  vps: 'essential',        // $30
  apiRequests: 500,        // ~$50
  backups: true,           // $10
  cdn: false,              // $0
