LPS Tool

What it does

LPS (Load, Performance & Stress) is an open-source tool that makes load testing simple, readable, and powerful. Define tests in YAML — no coding needed. Run distributed tests, monitor live dashboards, and simulate real traffic with smart iteration modes. Built by a Microsoft engineer with 13+ years in API Management & Security to make enterprise-grade testing accessible to everyone.

Professional load, performance, and stress testing tool with YAML-driven configuration. Free consultation available for enterprise testing strategies.

Describe your entire test in one readable YAML file — LPS spins up thousands of concurrent users and streams the results live. No scripting, no boilerplate. One declarative config in — real-time performance insights out. Built on Rounds and Iterations for organized, realistic testing scenarios that simulate real user behavior. Scale across multiple nodes with master-slave architecture for high-volume load testing. Monitor essential metrics with an intuitive dashboard that updates dynamically during tests. Dynamic value generation with built-in methods for random data, counters, timestamps, and more. Skip an iteration based on runtime expressions and variables — ideal for branching logic…from lpsload.io

  Loadjitsu – a modern load testing alternative to JMeter2022 · loadjitsu.com · ▲67

  Please meet Loadjitsu, my weekend project, years in the making. Over the years while building different apps and sites, I always felt that I need a modern load testing software.Tools like JMeter, ab are not very easy to use and it seems innovation in load testing which is a crucial part of any software release cycle has been ignored. This is my third attempt at making Loadjitsu, I am so glad that I can finaly release this. A bit more about the software 1. Powered by golang you can run load tests for tens of thousands of connections per second on very average hardware. 2. Cross platform, run…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
