The story of how we got started on the journey to providing a load testing SaaS app

It all started with a game...

In the year 2000, with the Y2K crisis in the rear view mirror, the two founders were working on a MMORPG. With a goal to support hundreds of players simultaneously the need for some early load testing arose. They opted to open a consultancy to aid organizations in load testing. The most notable customer from this era was the European Space Agency where we got to test IP satellite networks.

...then we added some Alligators...

Meanwhile - one of the founders started to take on a new hobby. An interest in reptiles, specifically Spectacled Caiman alligators. Two of them soon moved into our Stockholm office, Bert and Ed. Bert proved to be mischievous, and escaped on a few occasions. They eventually moved out to go live in more appropriate accommodations - however Bert’s legacy lives on serving as our mascot.

…we then shifted from consultancy to a SaaS organization….

Fast-forwarding to the year 2008 after years of consulting, we shifted gears yet again. The concept of “cloud computing” was emerging and the possibility to bring the load testing tool we created to market became a viable business model. Initially the focus was on website testing - DevOps was still a fringe concept only recently being coined.

… we knew gaps still existed in the market …

In tandem with the growth of DevOps, we started to notice gaps emerging in the market that we knew we could address. Users were no longer testing things one-off. APIs were becoming more prevalent in usage and required testing. Users wanted to test continuously. For many companies, testing was moving into the responsibility of developers.

… we decided to build a new tool from the ground up …

In 2016, Bert and the LoadImpact crew started working on a new open-source load testing tool. A tool that developers could love in the 21st century.

Moving on to the present day, early adoption has been fantastic and the k6 community quickly grew. We have something special in our hands and look forward to building it with you.

… extending core k6 …

Early 2020 we launched the first tool to extend core k6.
The xk6 extensions ecosystem is ever expanding, allowing for better integrations in users' existing stack.

… we joined Grafana Labs …

June 2021 we were acquired by Grafana Labs. Announced by Raj Dutt during his closing keynote at GrafanaCONline, we welcomed the opportunity to accelerate on our mission: to give modern engineering teams better tools to build reliable applications.

What our users are saying

@k6_io thank you for creating an amazing open source product. I wrote my own thread ripper for load testing and you just saved my socks with the integration tools you have by default. Anyone looking to do load testing highly recommend using k6. It also reminds me of snowboarding.

It's time for me to once again sing the praises of @k6_io. If you've ever written a load test I think you'll likely agree it is the grungiest of grungy tasks. k6 makes it fun. It's like Greasemonkey for load testing. Cannot recommend enough.

I'm 90% complet on my #PoC and in my professional opinion @k6_io is definitely a #gamechanger for #performance #testing allows #shiftleft excellent #docs support 4 #Docker #javascript custom #metrics and establish #thresholds to pass/fail #cicd builds for both #webui & #API

I've toyed with a few load testing tools over the years, but only today tried @k6_io, and wow, is it pleasant to use. Haven't tried the hosted version, but for quick and easy CLI stuff, absolutely wonderful.

Toying around with @k6_io tonight. Pretty impressed with how easy it is to set up (yay @Docker!) and to start building test scripts. Some early results: pic.twitter.com/LGCESvFMlv

I love products like @k6_io - very technical and geeky domain, yet the product is extremely user friendly and you can understand and start using it within *seconds*, not even minutes. Great job.

personally using @k6_io and its has helped us quite a lot already. Definitely worth adding to your testing pipeline.

Lately I have been using @k6_io for performance testing the RESTful APIs we build and I simply fell in love with it. It so simple and easy to use, i highly recommend it!!

Loving @k6_io for integrating perf tests into @AzureDevOps pipelines. Great documentation, easy to use..

So @k6_io is probably my new favourite tool. Super quick to get set up and running load tests 😻

For anyone interested in load / stress testing, I’ve been using @k6_io recently and has been an absolute pleasure. Script up your flow using JS and away you go. Load tests in source control FTW. API for build sever runs too, beautiful.

Holly Molly, using @k6_io to do stress test and send the metrics to #DataDog on real time, amazing tool.

Open source and written in #golang

Yesterday was awesome! I whipped up a @k6_io extension in @golang so my load tests can publish to @nats_io. Took about an hour and a half and the end result was 57 lines of Go :D #golang

Why people love k6?
