Performance Test

Run load tests against endpoints you own or have explicit permission to test.

Authorised use only. This tool is for performance and capacity testing of infrastructure you own or control. Sending load to any system without prior written authorisation from its owner is illegal in most jurisdictions and violates acceptable-use policies. You must confirm ownership before each test.

Docs

Quick reference for configuring and running tests.

Getting started

Enter one or more URLs you own or control, set concurrency and duration, check the consent box, then press Run Test. Results stream in real time on the right panel.

Concurrency

Number of simultaneous connections. Start low (5–20) and scale up. Most staging servers handle 20–50 without issue. Pushing above 100 against production risks real user impact.

Payload size

Adds a random body to POST/PUT requests to test throughput under realistic data sizes. Set to 0 for lightweight endpoint checks.

HTTP Proxies

Proxies let you distribute load from multiple IPs — useful for simulating real-world traffic from different regions. Supports HTTP, HTTPS, and SOCKS5 proxies. All proxies must be ones you own or have permission to use.
