API Rate Limiter Visualizer & Simulator
The NexVaani API Rate Limiter Visualizer and Simulator provides backend engineers, systems architects, and API developers with an interactive sandbox for testing traffic control algorithms. Compare the Token Bucket algorithm (which tolerates short traffic bursts) against the Leaky Bucket algorithm (which enforces smooth constant throughput). Test single requests or burst traffic to observe HTTP 200 OK vs HTTP 429 Too Many Requests backpressure and header calculations.
The NexVaani API Rate Limiter Simulator visualizes Token Bucket and Leaky Bucket rate-limiting algorithms, demonstrating burst capacity and HTTP 429 backpressure directly in your browser.

Frequently Asked Questions
What is the difference between Token Bucket and Leaky Bucket?▼
Token Bucket allows temporary bursts of traffic up to the bucket capacity, whereas Leaky Bucket forces requests through at a strictly constant rate.
What HTTP headers are sent with rate limiting?▼
Standard headers include `X-RateLimit-Limit` (quota), `X-RateLimit-Remaining` (available tokens), and `Retry-After` (seconds to wait).
