I made a platform to load and performance test API's
I built BuzzBench because I was frustrated with how complex performance testing tools have become. And I was ending up writing my own scripts to test endpoints and manually check out resource usage at the time of testing. Checkout demo: https://www.youtube.com/watch?v=yAnbZMoQvmQ
In plain words
BuzzBench is a platform designed to load test and evaluate the performance of APIs. It targets developers and teams who need to assess how their endpoints perform under stress without the complexity of traditional performance testing tools. The platform simplifies the process by eliminating the need to write custom scripts and manually monitor resource usage during tests, offering a more straightforward alternative to existing solutions.

Mocktail – Free, open-source mock API server with a built-in dashboard23d ago · getmocktail.com · ▲25Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…
- ASA Simple Load Testing CLI Built in Go2023 · github.com · ▲9
There are plenty of good tools for load testing such as JMeter, Minigun, and plenty more - but they all have their own set of options to learn. I built this one to support a simpler workflow where you just paste your curl request (or other cli command) after your `spam` config (literally just `spam -r 2 -- curl www.google.com). It's pretty barebones but I'm 100% going to use it in my day to day - figured I'd share it here if it helped anyone else!
- TRTrunchbull, run real models against any benchmark in your browser25d ago · trunchbull.dev · ▲6
Hi HN, Today I'm showcasing Trunchbull, a benchmarking platform designed for authoring benchmarks and running them against different models. We have direct support for benchmarks that use the harbor authoring system, custom tool authoring via the vercel ai sdk and configuration limits. We've also already imported terminalbench 2.0, as a sort of proof of concept that our harbor task orchestrator works, although you currently need a paid account as we are provisioning sandbox environments. I've made several popular benchmarks publicly available for testing. You dont need an account or your…
- SDSplunk Developer Platform (what I've been working on)2011 · ▲12
Hey HN, I wanted to share with you what I've been working on for the past few months – the Splunk Developer Platform[1]. We released our Python SDK[2] back in August, but just last week we released our Java[3] and JavaScript[4] ones, and the JS SDK was the one I've been working on. It was a great learning experience for me – first real foray into JavaScript and Node (the SDK works in both the browser and Node), and was a lot of fun to try different things out releasing it. I ended up building on a couple of open source libraries (and contributing back). We are building out Splunk's developer…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
