Built so it can’t be weaponized

Every target is verified before any traffic flows, and orchestrator-level rate guards cap RPS and duration on every run. Power-tested, never a DDoS tool.

Distributed by design

Traffic from every region you choose

Spin up stateless agents around the globe and storm your target from the geographies your users actually come from.

Capabilities

Everything you need to stress-test with confidence

Real load, real numbers, and guardrails that keep every run safe — from a quick smoke test to a full production spike.

Real-time metrics

p50 / p95 / p99 latency, RPS, and error rates stream to your dashboard the instant each agent fires — no batch delay, no refresh.

Distributed agents

Spin up stateless load agents across regions and generate realistic global traffic in seconds.

Verified targets only

Every target is proven yours via DNS TXT or HTTP header token before a single request leaves an agent.

Rate guards built in

Max RPS and max duration are enforced at the orchestrator — not just the UI — so a test can never run away from you.

How it works

From zero to storm in three steps

No agents to install, no infrastructure to babysit. Verify, configure, and watch the metrics roll in.

01

Verify your target

Prove ownership with a DNS TXT record or HTTP header token. No verification, no traffic — ever.

02

Design the storm

Set your RPS ramp, duration, regions, and request scenarios. Rate guards keep every run inside safe limits.

03

Watch it live

Stream latency percentiles, throughput, and errors in real time as agents fire across the globe.

Tests as code

Declarative tests your team can review

Describe the storm once and replay it on every release. Targets, ramps, regions, and safety guards live in one readable spec — version it, diff it, ship it.

FAQ

Questions, answered

What is load testing?

Load testing simulates many concurrent users hitting your app so you can measure latency, throughput and error rates under stress — and find your breaking point before real traffic does.

Is Rampstorm free?

Yes. Every plan is free during the closed beta, including distributed regions and live metrics. Paid plans arrive after launch, and the Hobby tier stays free forever.

How do you stop it being abused?

You must prove ownership of every target with a DNS TXT record or HTTP header token before any traffic is sent, and orchestrator-level rate guards cap RPS and duration on every run.

Can I generate traffic from multiple regions?

Yes. Rampstorm spins up stateless load agents across regions on demand, so you can test your target from the geographies your users actually come from.

Do I need to install anything?

No. Rampstorm is fully cloud-based — no agents to install and no infrastructure to manage. Define a test, verify your target and hit run.
