Rate Limiter Dashboard

React + Vite dashboard for the ratelimit backend. Provides:

Live KPI cards — Total / Allowed / Denied / Cache Hit Rate
Real-time chart — requests per second, polled every 1s
Load Tester — run controlled load against any of the four algorithms from the browser
Algorithm Comparison — stacked bar chart of allows vs denies per algorithm
Key Inspector — raw Redis state for any key across all four algorithms, with live watch mode

Running

The dashboard expects the backend at http://localhost:8080.

# Start the backend first (in the ratelimit repo)
docker compose up -d
go run ./cmd/server

# Then the dashboard
npm install
npm run dev

Real screenshots from an actual running instance — not mockups.

1. Load test results — 1,000 requests at 50 concurrency against Fixed Window (limit 100/60s), showing the real allow/deny split and RPS:

2. Algorithm comparison — the same load test run against Token Bucket, Fixed Window, and Sliding Window Log back to back:

See sameer-sde/ratelimit for the Go server, four algorithms, hash ring, LRU cache, and benchmarks.

Built as part of a learning project — distributed rate limiting in Go, benchmarked to 18,769 req/s at p95 16ms.
