Open-source load testing on AWS Lambda. With built-in cost reporting
Hiya HN! tldr: Artillery is an open-source load testing toolkit. It's cloud-native, i.e. you can scale out your test with AWS Lambda (other runtimes coming soon). There's no infra to set up or manage - you give Artillery an AWS account, and it takes care of the rest. We just released an update which includes cost reporting. Every time you run a load test, Artillery will show how much that cost in AWS Lambda fees.

In plain words
Artillery is an open-source load testing toolkit that runs on AWS Lambda without requiring infrastructure setup or management. Users can scale distributed load tests by providing AWS account credentials, and the tool automatically handles execution. A built-in cost reporting feature displays AWS Lambda fees for each test run, helping teams understand testing expenses. The software is designed for developers and QA teams who need to perform load testing at scale with minimal overhead.

In the maker’s words, at launch
Hiya HN! tldr: Artillery is an open-source load testing toolkit. It's cloud-native, i.e. you can scale out your test with AWS Lambda (other runtimes coming soon). There's no infra to set up or manage - you give Artillery an AWS account, and it takes care of the rest. We just released an update which includes cost reporting. Every time you run a load test, Artillery will show how much that cost in AWS Lambda fees. Blog post with a demo here: https://www.artillery.io/blog/this-load-test-cost-us-how-much The demo shows a distributed load test running in us-east-1 at 100k+ RPS for about 10 minutes. Total cost is $1.23. We constantly hear from our users how cost is one of the biggest barriers to load testing more frequently. We're making cost much less of a factor with Artillery, and hoping that will unlock load testing at scale to more teams. Would love to hear what the biggest barriers are for you with load testing!

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
