Run API load tests in seconds. Get clear answers instantly. No infrastructure required.
API performance testing today is painful:
- ❌ Complex tools like JMeter, k6, Locust
- ❌ Requires scripting, setup, and infrastructure
- ❌ Hard to interpret metrics (avg vs p95 vs spikes)
- ❌ Test data and payloads stored (security risk)
- ❌ Overkill for quick debugging or validation
You just want a quick answer:
“Can my API handle this load or not?”
PerfDash is a stateless, browser-based API performance testing tool
built for developers who need fast, simple, and secure insights.

“Why does my graph show 100+ RPS but average is only 30?”
PerfDash helps you clearly see:
- Peak vs average throughput
- Latency distribution (p95/p99)
- Ramp-up effects
No confusion. Just clarity.
