Two ways to test

Choose your weapon

Raw HTTP speed or realistic user simulation. Both run from 4 continents simultaneously, stream live metrics, and deliver a PDF report when done.

Quick Load Test

Paste a URL. We hammer it with real HTTP traffic from up to 4 continents at up to 100,000 requests per second. See latency percentiles, error rates, and throughput in real time.

  • Up to 100,000 RPS sustained
  • Latency p50 / p95 / p99 per region
  • Per-second streaming metrics
  • Status code distribution
  • PDF report with graphs
Free tier: 100 RPS · 1 minute · 1 region · $0

Scenario Test

Simulate real users clicking through your app with Playwright. Upload a script, record your own journey, or build steps visually. Each scenario is saved as an encrypted .loadtest file — you keep it, we forget it.

  • Upload Playwright scripts or record live
  • Visual step builder (no code needed)
  • Up to 500 virtual browsers at once
  • Per-step latency breakdown
  • Error screenshots in report

Connect your wallet. One-shot payment for this test. No recurring charges.
4
Watch it live, get report
Real-time streaming metrics. When done, download your PDF report. We delete everything.

Scenario Test

1
Create your scenarios
Upload a Playwright script, record your journey through your site, or build steps visually. Download as encrypted .loadtest files.
2
Upload & configure
Upload your .loadtest files. Set what percentage of users run each scenario (must total 100%).
3
Verify & pay
Domain verification, then pay once. Price is based on virtual user count and duration.
4
Live browsers, rich report
Watch virtual browsers execute your scenarios. PDF report includes per-step timing, bottlenecks, and error screenshots.

Run Heavy Test

All payments in USDC or USDT. Non-refundable. You must own or be authorized to test the target domain.

Anti-DDoS protection

Domain verification

Before any test begins, you must prove you control the target domain. This prevents LoadTester from being used as a DDoS tool against sites you don't own.

1

Start a test — get your verification ID

When you configure a test, we generate a unique test ID (e.g. lt_a3f9b2c1).

2

Serve a file at the verification path

Create a file at /.well-known/loadtester-verify/{test-id} with the content we show you.

# Example: serve it with any web server mkdir -p /var/www/.well-known/loadtester-verify echo "lt_a3f9b2c1:verified:2026" > /var/www/.well-known/loadtester-verify/lt_a3f9b2c1 # Or with nginx, just add: location /.well-known/loadtester-verify/ { root /var/www; }
3

Click "Verify" — we check it and proceed

We fetch the file to confirm it's there. Once verified, you can pay and launch the test. The file can be removed after the test ends.
