Know how much traffic your site can take
Load test websites and APIs with realistic multi-step user flows, find the breaking point, and share a clear report. Powered by k6.
Everything a load test needs
From the first request to the report you send your client or your boss
Real user flows
Chain steps like login → browse → checkout. Tokens and cookies flow between steps automatically.
Find the limit
LoadLab adds users level by level and stops when the site gets too slow, then tells you how many it handled and why it broke.
Import what you have
Start from a Postman collection, an OpenAPI / Swagger file or a browser recording (HAR). Or crawl your site.
Server and browser monitoring
Record CPU and memory on your servers during the run, and Core Web Vitals from real Chrome users.
Schedules and alerts
Run tests on a schedule and get Slack, Telegram, email or webhook alerts when a run fails or gets slower.
Reports and CI/CD
Branded PDF reports with an executive summary, and a CI step for GitHub Actions or GitLab that fails the build on regressions.
How it works
Build the flow
Add steps, import an API spec, or crawl your website.
Try it once
Run one user through the flow to check every request and response.
Apply load
Ramp, spike, constant or find-the-limit, with live charts and a stop button.
Read the report
Per-step stats, an error breakdown and a comparison with earlier runs.
Built for teams and agencies
Organise tests into projects per client or website, control who sees what, and put your own logo and colours on every report.
Prefer a done-for-you test?
Our team can plan the scenarios, run the test against staging or production, and walk you through the results.
Talk to usOnly test systems you own or have written permission to test. Load testing someone else's site without permission is treated as a denial-of-service attack.
