Rate limits are the bane of every developer's existence. You're building something cool, hitting an API, and suddenly: 429 Too Many Requests.
The common solutions:
- Pay for a higher tier 💰
- Implement complex retry logic 🔄
- Rate limit your own requests ⏱️
But what if you could just... use more keys?
Introducing Rotato
Rotato is a lightweight API proxy that automatically rotates through multiple API keys. Drop it between your app and any REST API, and it handles key rotation transparently.
Your App → Rotato (rotates keys) → API Service
How It Works
- Configure Rotato with multiple API keys
- Point your app at Rotato instead of the API directly
- Rotato forwards requests using a different key each time
- When a key hits its limit, Rotato automatically skips to the next
Your app code doesn't change at all. It just talks to one endpoint.
Use Cases
OpenAI / LLM APIs
Have 3 free-tier OpenAI keys? Rotato gives you 3x the rate limit without paying a cent.
Google Maps
Distribute API calls across multiple project keys to stay within free quotas.
Any REST API
If it uses API keys and has rate limits, Rotato can help.
Features
