Products that do what Loadjitsu – a modern load testing alternative to JMeter does
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…

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!

Hi HN, 8 months ago, I posted “Ask HN: I built it nobody came, what now?” and got a ton of (not very optimistic) feedback [1]. I took away 3 things: 1. The message wasn’t properly targeted 2. The onboarding experience was terrible. 3. Someone posted some advice to find leads which actually worked, yeah! So here we are. 8 months later. I unfortunately didn’t have a lot of time to put in the tool itself. But I improved the website, improved the onboarding, and got a paying customer who seems to really like the software. So here it is in its current form. Let me know what you think would make…

I'm a long time lurker that recently quit my job to work on my own projects, a lot due to the inspiration from Hacker News. Now I have published my first serious project, an app for learning how to write Japanese characters. It's the app I always wanted but couldn't find when I was studying. It tries to be simple to use, you just start the quiz and go with the flow. There's no need to plan and manage your studies, and it uses spaced repetition for better retention. There's a promo page with more details up at http://www.kanjibyhand.com. It's only for Android so far. The free version includes…

Hi HN, Meng from TabbyML here. We decided to build this simply because we find Jujutsu (jj) really interesting, and many folks on our team have started trying it out recently. Since it introduces a very different workflow compared to traditional Git, we thought it would be a fun challenge to see how well current AI coding agents can actually use it. To build this, we created a semi-automated pipeline. We used AI to research the official Jujutsu documentation and websites, which then helped us bootstrap a dataset of 63 distinct evaluation tasks. Each task includes instructions, bootstrap…

Logging work to Jira does not suck anymore. Check out second version of the tool that makes your work logging life easy ;) Since the first version was a POC cranked out in not more than 2 days, the second iteration took me some more time to craft things with much more care. Have fun checking it out, feedback is appreciated.

Hi HN,<p>In my spare time (evenings and weekends) I've built 3 products which have been relatively successful even with little advertising (only google ads budgeted at $30 per day). The latest one is WcfStorm.Rest; which is a REST service test client. I built it because I found that the current tools did not have the features I wanted such as, intellisense when working with HTTP headers, syntax highlighting for JSON messages, etc.<p>I'm continually trying to improve these products and would very much love get your feedback. Every suggestion is welcome!<p>(My apologies…

We built StripeMeter, an open-source usage metering platform that plugs directly into Stripe. It solves the classic SaaS pain of “why is my bill higher than expected?” by giving both developers and customers real-time usage tracking with live cost projections. Why it matters: - Transparency: Customers see exactly what Stripe will bill them (within 0.5% parity). - Exactly-once guarantee: No double billing, ever. - Fast & scalable: Sub-minute freshness with Redis + Postgres counters. We’d love feedback from SaaS builders, especially if you’ve struggled with Stripe’s metered billing. Does this…

Hey HN! I built Experiment to solve a common frustration in LLM development: the lack of proper tools for prompt engineering experimentation. Here's what makes it different: Key Features: - Load and edit chat completion logs from CSV files - Fork and modify specific conversation entries - Run inference via Anthropic, Mistral, and OpenAI - Define custom tools using JSONSchema format - Visual tool usage analysis with collapsible, sorted key-value pairs - Full mobile support and available as installable PWA Technical Highlights: - Built with React using custom isomorphic architecture -…

Hi HN! I'm Nick, one of the cofounders of Bitping, and we'd like to share a tool that we've been working on for the past couple of years that lets you test network connectivity from real user devices around the world. We originally were part of a hackathon focused on building a product that is powered by micropayments and we settled on a network that could ping other network devices and users could be paid in fractions of a cent for performing said work. After winning the hackathon, we built an uptime monitoring service and discovered some discrepancies between our data and traditional…

After fine-tuning GPT for a personal project, I realized how tedious it is to write plain text in a massive JSON file. That's why I built this app for my own use, and I want to see if others could benefit from a tool like this as well ;)

Hi HN, I've been working with LLMs in production for a while both as a solo dev building apps for clients and working at an AI startup. The one thing that always was a pain was to pay OpenAI/Gemini/Anthropic a few dollars a month just for me to say "test" or have a CI runner validate some UI code. So I built this server called ChunkBack, that mocks the popular llm provider's functionality but allows you to type in a deterministic language: `SAY "cheese"` or `TOOLCALL "tool_name" {} "tool response"` I've had to work in some test environments and give good results for experimenting…

Hello HN! I've been building this side project which is a task manager as simple and as powerful as I've been able to built it. It's specially thought for the tasks that you must complete at work, and you want to remember but you want to avoid all the bureaucracy of some TO-DO apps like JIRA. It's been quite a journey to build it. Its backend lives in Amazon Lightsail, and for now it's a Django app with a SQLite database. I'm quite surprised on how good SQLite has been performing on all the tests so far. The frontend it's a React app. Everything is pretty standard, but those are technologies…

I was overspending on GPT-4o. It was really hard to compare different models I could switch to, so I built this LLM comparison tool. It shows leaderboards, pricing, and performance data across 100+ LLMs (including all major providers and open-source models). Key features: - Live pricing comparisons - Benchmark Scores (MMLU, HumanEval, GPQA, etc.) - Context length vs cost analysis - Speed/throughput tests across providers - Quality vs price visualizations - Open source (all data verifiable) Try it out: https://llmstats.com I'd like to know your opinion :) Tech stack: Next.js,…
