Your launch takes off
Product Hunt, viral post, first ad campaign... and your server crashes at the worst moment.
Test before you scale
Will your app survive when it goes viral?
Find out if your site can handle 100, 1,000, or 10,000 visitors at once — before they actually show up.

What AI foundAction needed
Your checkout page slows down after 50 visitors. Recommendation: optimize database queries.
The problem no one anticipates
You build your app, everything works perfectly with a few users. Then one day...
Your app gets slow
Pages take 10 seconds to load. Users leave. You don't know why.
Errors cost money
Abandoned carts, failed signups, lost customers. Every second of slowness = money lost.
Imagine a restaurant that can serve 10 customers. One day, 200 people show up at once. Service collapses, customers leave angry. That's exactly what happens to your app when it gets too many visitors.

I launched my SaaS on Twitter. LoadLab showed me my app crashed at 50 users. Fixed it before the buzz!

Zero performance knowledge. I just entered my URL and AI told me exactly what to optimize. Magic.

How does it work?
3 steps, no technical skills required. Developers can go deeper with OpenAPI import.
- 1
Enter your app's URL
Just paste your website or API address. For developers: import your OpenAPI/Swagger spec.
- 2
Choose how many visitors to simulate
50? 500? 5,000? Simulate the traffic you expect (or dream of).

Frequently Asked Questions
Everything you need to know about Loadlab. Can't find your answer? Contact us.
Loadlab is designed for teams who want load testing without the complexity. Unlike k6 or Gatling which require scripting, Loadlab lets you import your OpenAPI spec and start testing in minutes. Plus, you get AI-powered insights automatically.
Yes! Loadlab is built for CI/CD integration. Use our REST API to trigger runs from GitHub Actions, GitLab CI, or any other pipeline. Each run generates a performance badge you can add to your README.
The free tier supports up to 100 virtual users. Pro plans support up to 1,000 VUs, and Enterprise plans can scale to 10,000+ VUs with distributed execution across multiple regions.
We track response times (avg, p50, p95, p99), requests per second (RPS), error rates, and throughput. All metrics are stored as time series data so you can see how your API performs throughout the test.
Yes. We never store your actual API responses. Only metadata and performance metrics are kept. All data is encrypted at rest and in transit. Enterprise plans include SOC 2 compliance.
