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
- 🔄 Round-robin key rotation
- 🚫 Automatic 429 detection and key skipping
- 🏥 Health check endpoint
- 📊 Request logging
- 🪶 Zero dependencies
- ⚡ Minimal latency overhead
Quick Start
git clone https://github.com/p32929/Rotato.git
cd Rotato
# Add your API keys to config
npm start
Then change your API URL from api.service.com to localhost:3000. Done.
If rate limits have ever cost you time or money, star this repo. It'll pay for itself on the first use.

Good idea, How do you securely store the access keys?
In your examples Bearer [STATUS_CODES:429][ACCESS_KEY:your-access-key]
what do you mean by status codes?
