Loady — Paste a URL. Feel the load.

Loady is a browser-based load testing tool for engineers who need to know how an API or website behaves under pressure before their users find out.

How it works

Paste a base URL or import an OpenAPI spec or Postman collection. Loady discovers the endpoints and builds a runnable scenario.
Set virtual users and duration. Load runs from cloud workers using k6, with live RPS, latency, error rate and SLO thresholds in the browser.
Get a verdict. Claude, Anthropic's AI model, reads the run's metrics, thresholds and logs and explains in plain language what broke, why, and what to try next. It can also draft a k6 script from a description.

Access is currently by invitation.
