We built Stolos to take the chaos of enterprise development environments and put it into order. Stolos runs the apps developers work in a remote, company-wide Docker cluster, while letting them use the editors and IDEs they love — from Vim to Visual Studio Code. It just works.

We help companies build modern, rock solid applications and workflows with confidence, rapidly with our battle tested experience with Docker, Python, Postgres, Terraform and DevOps in production over the last decade.

We provide trainings via 2hog. We provide distilled and spot on knowledge and teach all that we have learnt the hard way in production.

Open Source


Xterm.js, the terminal used by SourceLair IDE, Visual Studio Code, Katacoda and more was built here. We are strong believers in open source and that's why we strive to create projects with impactive, under permissive licenses, like xterm.js.

Ceryx is a ridiculously fast reverse proxy, programmable via an API and all that built on top of NGINX' robust foundation. We built Ceryx out of the need to serve hundreds of thousands of projects through a unique domain name each.

Stolos, our enterprise Docker development product, runs on our customers' servers, so we want to establish a great level of trust. That's why we have released the foundation of Stolos open source on GitHub.

We have been working on building products and providing services helping developers across the planet work more efficiently and pleasantly for a decade now. Don't just take our word for it though. Here is what some of our customers have to say about us:

SourceLair IDE
I just have all things in one place and can access it on every computer without installing software. This is perfectly easy and saves a lot of time. And I don’t need to cary my laptop everywhere
I gained deep knowledge of the most contemporary software architecture methods. The material was adequate and the instructors well prepared and experts in this domain!
SourceLair IDE
SourceLair has allowed me to effortlessly continue to work remotely. Prior, I was forced to work on a specific project at each of the different work environments. Now, I am easily able to carry all my projects with me whenever I go!
Very hands-on workshop. The instructors are very passionate about the subject and they make the whole experience funny and educational.
SourceLair IDE
SourceLair IDE has provided me with portability. Now I can use any device to code my projects.
