How it works

Your QA flow, end to end

No code at any step.

  1. 01

    Record or migrate

    Record the flow from your browser or bring your JMeter .jmx files.

    $ relampo record --port 8888

  2. 02

    Correlate

    Tokens, sessions and CSRF resolved automatically, 100% local.

    $ relampo correlate scenario.yaml --apply
    See how
  3. 03

    Debug with 1 VU

    Check every request and response before launching thousands.

    $ relampo studio scenario.yaml

    Run & scale

    Locally or distributed on your CI, with an HTML report for your team.

Why Relampo

The hard part of scripting, solved

Correlation, deterministic and 100% local

Relampo finds tokens, sessions and CSRF in your recording and rewrites the YAML for you. Your recordings never leave your network.

Understands ASP.NET, GeneXus and SAP, plus any web app.

Relampo Studio: visual, with 1-VU debug

A tree of requests, controllers, extractors and assertions, in sync with readable YAML. Debug with one virtual user before you scale.

Watch the tourOpen the editor

Your AI agent speaks Relampo too

With the Relampo skill, Claude Code, Cursor or Copilot write, correlate and run the YAML for you.

Massive load, without breaking the bank

You only pay for orchestration, load generation and analysis. Everything runs on your CI (GitHub Actions or GitLab CI), with a monthly VU package and unlimited tests.

JMeter migration

Coming from JMeter? Bring your .jmx

Your AI agent, with the Relampo skill, migrates your JMeter test plans to Relampo YAML. Same concepts you already know, without the heavy GUI.

  1. 1Give your .jmx to your AI agent with the Relampo skill
  2. 2Get a readable Relampo YAML
  3. 3Validate it and run it with one VU before you scale
Measured performance

10,000 virtual users.One single node.

A full purchase journey, from login to logout, with sessions, data correlation and tokens processed in JavaScript.

Relampo plans

Start free on your machine. Scale when you need it.

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.

01 · Local

Core

From your browser to a load test in minutes. The engine runs on your machine, on a single node.

Freeforever
Unlimited VUs
As many as your machine can handle
  • Tests up to 1 hour, 300 minutes per month
  • Traffic recorder that generates the YAML
  • Dynamic value detection: tokens, sessions and CSRF
  • Load by Intent: set the goal, the engine adjusts the load
  • Relampo skill for your AI agent

Dedicated support and SLA

On your machine: unlimited VUs on every plan. Your hardware is the only cap.

Distributed: peak concurrent VUs summed across all nodes. With Load by Intent, the engine never goes above your plan’s cap.

High-scale distributed runs may require larger runners or additional capacity in your CI.
FAQ

Questions QA teams ask us

Can I capture HTTP traffic from my browser?

Yes. relampo record starts a local proxy: point your browser to it, browse the flow and Relampo generates the YAML with every request and its response. For HTTPS, you trust the Relampo certificate once.

Do I need to know how to code?

No. You record the flow, Relampo correlates it, and you edit it visually in Relampo Studio. If you prefer code, everything is readable YAML.

Does correlation create the regular expressions for me?

Yes. Relampo detects the dynamic values, creates the extractors (regular expressions, JSONPath or headers) and replaces each value with its variable in the YAML. Deterministic and 100% local.

What if I need logic the components don't cover?

You can extend it with Spark: JavaScript blocks that run before or after a step to transform data, calculate values or add your own logic.

What is Load by Intent?

You define the goal instead of the users: for example, a target RPS per segment, with a minimum and maximum of VUs. The engine adapts the virtual users to reach it, without exceeding your plan cap.

Can I run virtual users from my own machine?

Yes, with Core, for free: as many virtual users as your machine can handle. The limits are on time: tests of up to 1 hour and 300 minutes per month.

And if I want to run distributed?

Relampo runs it on your GitHub Actions or GitLab CI runners, with no infrastructure of your own. Scale plans start at $9.99 a month with 500 distributed VUs and go up to 10K VUs; beyond that we size it with you.

Can I migrate my scripts from JMeter and other tools?

Yes. Give your scripts to your AI agent with the Relampo skill and you get a Relampo YAML, ready to validate and debug with one virtual user.

Can I export my Postman collection to Relampo YAML?

Yes. Your AI agent, with the Relampo skill, converts your Postman collection into a Relampo YAML load test.

Do my recordings leave my network?

No. Recording, correlation and test execution run on your machine or on your own CI. Relampo only connects to validate your plan license and, if you opt in, to share usage metrics.

Your next load test,without writing a line of code.

Record, correlate and run load tests without writing code. Free on your machine, distributed on your own CI when you need to scale.
