Edit your test as a tree of scenarios, requests, controllers, extractors and assertions, just like you are used to. Debug with one virtual user, check every request and response, then scale with confidence.
Common node blocks you can configure visually

Five QA and performance projects run with Relampo. Company names are omitted for confidentiality.
Found the root cause before a campaign: the first load error matched, to the second, the first lock in the database.

Read the full caseMore than 15% of daily runs caught a performance regression in staging, before it reached production.
Read the full caseMixed web and device load showed the auth service scaled, and pinpointed the web login step as the one that didn’t.
Read the full caseValidated the 10,000-user target and measured the margin above it, up to the point where the platform starts to saturate.
Read the full caseGitHub Actions and GitLab CI, with no dedicated infrastructure. Scenarios in YAML, with no code.
On your machine, virtual users have no limit on any plan. What changes between plans is distributed execution and the tools that come with it.
From your browser to a load test in minutes. The engine runs on your machine, on a single node.
Relampo orchestrates the test on your CI runners: you bring the infrastructure, we coordinate the whole test.
No runners, no setup.
Your hardware is the only cap. Applies to Core and every Scale plan.
We count peak concurrent VUs, summed across every node. With Load by Intent, the engine never goes above your plan’s cap.
No lock-in. The load runs on your own infrastructure.

Readable, portable YAML with a documented format. Your recordings never leave your network.
A small team obsessed with making performance testing accessible to everyone
The one who started it all: created the first MVP and brought the team together. Faithful lover of performance testing, always looking for smarter (and less painful) ways to break systems before they break in production.
The guy who turns ideas into real, working products. Full-stack mindset (backend + frontend) and super hands-on – he's the technical engine behind the team.
The organizer who brings structure and focus. She keeps the team aligned and makes sure all the effort actually turns into a clear, meaningful product.
Record, correlate and run load tests without writing code. Free on your machine, distributed on your own CI when you need to scale.
