#1 IP Stresser — Free Stresser for Authorized Load Testing
stresser.works is the leading IP stresser for authorized load testing. Professionally verify the resilience of your own servers, networks and applications against DDoS-grade traffic — with a free stresser plan that goes live in minutes.
What is an IP stresser?
An IP stresser is a specialized load testing tool that generates high-volume traffic against a server to reveal weak points before a real attack does.
As the #1 IP stresser for authorized load testing, stresser.works combines 25+ Layer 4 and Layer 7 DDoS testing methods with a globally distributed network of up to 1.7 Tbps aggregate capacity and real-time monitoring — all from one clean console.
DDoS stress testing, done right
Unlike basic online load testers, our DDoS stresser supports amplified UDP, TCP and SYN floods, HTTP/HTTPS bypasses for Cloudflare and Sucuri, and full REST API automation for security pipelines. Every test launches within seconds, streams live packet statistics, and stops automatically when the duration ends.
- Instant launch in ~3 seconds
- Layer 4 & Layer 7
- Cloudflare & Sucuri bypass
- Real-time monitoring
Built for serious load testing
Every feature is engineered for professional security teams and network engineers.
Instant launch
Tests start within seconds after node assignment. Stop manually or let them expire automatically.
Zero logs policy
No IPs, no targets, no activity stored. Privacy by design, enforced by architecture.
Global network
100+ edge locations across NA, EU, Asia and the Middle East with 1.7 Tbps aggregate.
L7 bypass methods
Advanced HTTP/HTTPS floods that emulate real browsers and bypass CDN protections.
REST API
Start, monitor and stop tests from code. Integrate into your security pipeline in minutes.
Real-time stats
Live packet rates, bandwidth and method telemetry while each test is running.
How it works
From signup to your first test in under 60 seconds.
