Open Source Proxy Turns Multiple Free API Keys Into Unlimited Rate Limits

Rotato addresses a perennial developer problem with an elegant solution: instead of paying for higher API tiers, simply rotate through multiple free keys automatically. The tool transparently handles key rotation without requiring application changes, making it immediately valuable for anyone using rate-limited APIs like OpenAI or Google Maps. By essentially multiplying available rate limits at zero cost, it shifts API spending from a fixed overhead to potentially optional.
