The list below shows the technologies we use in our daily work. We are big advocates of open source technology, because of the stability, openness and customization possibilities of these libraries. The usage of an open source technology stack helps our customers to keep IT costs low, as no software license fees have to be paid.

Software and Web-Development Languages

Python is our weapon of choice for most use cases. It is easy to maintain, beautiful to read, has a great community around the world and is used by Google, Twitter, Pixar and many more.

XCode is an integrated development environment (IDE) for developing software for OS X and iOS. It allows us to create native IPhone and IPad apps.

JavaScript is a dynamic computer programming language. We use it to do create dynamic stuff at the front-end, and to create non-blocking server side applications using nodejs.

AngularJS is an open-source JavaScript framework maintained by Google that allows us to build huge JS applications.

HTML5 is a markup language for structuring and presenting content in the internet, and allows us to build apps that run everywhere. From PC to Smartphone to TV.

CSS3 is a web-based markup language used to describe the look and feel of a website. It helps us to make our applications look appealing and beautiful.


Django is the web framework for perfectionists with deadlines. It is a high-level Python web framework that encourages rapid development and clean, pragmatic design.

PhoneGap allows us to create mobile applications using standard web technologies that run everywhere. From IPhone, to Android, to WindowsPhone.

nodejs is a software platform that is used to build scalable network applications. It allows us to build web applications that are incredibly fast.


PostgreSQL is the worlds most advanced open source database. PostgreSQL is famous for its reliabilty and its stability.

MongoDB is an open-source document database, and the leading NoSQL database.

Redis is an open source, advanced key-value store. It is known for its performance as it stores data in memory, while having also build-in persistence.

Cassandra database is the right choice when you need scalability and high availability without compromising performance.

Threading, Messaging and Queues

Celery is an open source asynchronous task/job queue. It is focused on real-time operation, but supports scheduling as well.

RabbitMQ is used for sending and receiving messages. Data delivery, non-blocking operations, push notifications or asynchronous processing are common tasks executed with RabbitMQ.

System Administration and Source Code Management

Linux is the free operating system that powers thousands of webservers today. It is known for its stability, configurability and performance. We run our applications on Linux powered webservers.

We provision our webservers using SaltStack. It helps us to maintain all the configuration stuff in one place and run our servers more secure and more stable.

git is a revision control and source code management software. It helps us to organize our source code and work in parallel. GitHub helps us to collaborate and facilitates the process of deployment.
