Overload.su is a UK-registered IP stresser and load testing platform run by a five-person team. 20,000+ clients. 50,000+ tests a day. Tier 7 dedicated servers.
Overload.su is an IP stresser and load testing platform operated by 78 OVER 37 LIMITED, a registered company in London, United Kingdom. Founded on August 18, 2024 by CEO Jordan McRae, it grew past 20,000 clients in its first year and now runs more than 50,000 professional-grade load tests every day. The platform works as a web attack panel: you verify ownership of a target, pick a test method, and the system launches controlled Layer 4 and Layer 7 traffic from dedicated Tier 7 servers on a custom network backbone, with botnet-powered L4 capacity from 40 Gb/s up to 20 Tb/s. Alongside the stresser, Overload.su bundles automated ULP Leak Check, pentest tooling and a takedown service. It is useful because it shows exactly where your infrastructure breaks before real traffic or real attackers find out, and instant execution means results arrive in seconds, not days.
Professional-grade load tests executed every day across client infrastructure.
Companies and individuals verifying their systems before attackers do.
January 2025 platform redesign multiplied server capacity fivefold.
Constantly updated application-layer methods that set world records, find vulnerabilities in targets and ride the fastest networks available.
Flexible Layer 4 methods with real power — from 40 Gb/s up to 20 Tb/s — outperforming competitor defenses.
Automated leak detection bundled into the panel, plus a pentest toolkit and a paid takedown service for malicious infrastructure.
Testing is restricted to resources you own or are authorized to test. Government, banking, education and critical infrastructure are off-limits by the Terms of Service.
Create an account on overload.su and confirm ownership or authorization for the resource you want to test.
Choose an L4 or L7 attack vector, set duration and power, and launch the test instantly from the panel.
See where latency spikes, where the stack saturates and what fails first. Fix it before a real incident does it for you.
