This is a great blog post! just taking the opportunity here to comment on this: > Finally for full scale high fidelity load tests there are relatively few tools out there for browser based load testing. It exists as of a few months ago a

Don't write your own load testing tool other than as a fun little exercise. At least not without understanding coordinated omission and thinking about workload modeling (open? closed? hybrid? all of the above?) [1]. Get this wrong and

curl is fantastic. There's also HTTPStat which provides a waterfall visualization on top of curl timings: https://github.com/reorx/httpstat There's also Skytrace (made by yours truly), which provides timing i

The main thing about the advice comes immediately before the bit you’re zooming in on. Want to talk to people who have seen hundreds of companies deal with what you’re dealing? YC is great for that.

Did YC S21 which was an all remote batch. my 2c. YC is 100% what you make of it. It's not a lean back experience. I did not meet most of the companies in my batch but I've gotten to know many founders through YC that I would not h

This lets you load test with Playwright (very similar to Puppeteer): https://github.com/artilleryio/artillery-engine-playwright

Yes indeed but wrk2 or Vegeta is still better for this particular use case (unless k6 has support for setting a constant RPS rate, afaik it does not), as otherwise the overhead of establishing a new TCP connection for a single HTTP request

Yep, k6 suffers from coordinated omission [1] with its default settings. A tool that can send a request at a constant rate i.e. wrk2 or Vegeta [2] is a much better fit for this type of a performance test. 1. https://www.scylladb.

Bombardier is cool, but serves a very different use case. I mentioned elsewhere in the comments that we have a Docker image, and are working on other methods of installing the CLI to alleviate some of these dependency-related concerns. Gett

I haven’t come across Hurl before. It looks cool!

Yes, those dependency trees can be large. Yes, supply chain attacks are a real threat. But Node isn’t that different than Python or Ruby in that regard. How far down the stack do you personally choose to go? I trust you’re familiar with tha

thanks for trying it out! adding “make timeouts configurable” to the todo list. you’re right on that YAML-as-JSON thing. If everything is quoted as JSON, those type conversions shouldn’t kick in. Otherwise there’s room for surprises - perh

“mini” in the sense that it doesn’t do everything that curl does. curl does a whole lot. this tool focuses on more common use cases and makes them friendlier. plus with request waterfalls and assertions it does things curl can’t do. the num

sure, that’s a valid concern in some environments. fwiw we use Snyk.io for dependency scanning

Yeah so the JSON quoting part is something I’m pretty pleased with. We use a YAML parser (JSON is a subset of YAML) to parse those values, which is what allows for double quotes to be omitted. Good point on iterating on the query! We alread

A few things :) Syntax highlighting Request performance waterfalls Built-in JMESPath queries for JSON (same syntax as in AWS CLI). XML and HTML can be queried too. Ability to set checks on the response. This one is super handy for quick acc

curl is amazing! I love curl. This is not meant to replace it completely. Probe just makes those most common use-cases friendlier, like looking at headers, or inspecting JSON retuned by an API with syntax highlighting, or querying without n

thank you! we just grab the timings info for the request from the underlying HTTP library, and sprinkle some ASCII art on top. That part was inspired by httpstat [1] We want to extend those with support for Server-Timing next, and also Core

if you’re on a Mac, Artillery has a Homebrew formula too. We have an official Docker image too. Other ways of installing are on the roadmap too (self contained tarballs and binaries). As to what it does better than curl/wget. Probe is
