  • Flexibilty

Open source licenses, puts no restrictions on the use and distribution of software and the users have access to the source code.

  • Innovation

The developers and organizations operating in the open source environment stand out for their high agility and readiness to innovate. Open source communities that have achieved a critical mass can by all means stand comparison with the development departments of commercial manufacturers – or even beat them in terms of response time and innovation. 

  • Quality

Disclosure of the source code creates enormous quality pressure on every developer in the Open Source Community.

  • Avoiding lock-in to one supplier

The very basis of Open Source software is an openness that ensures interaction between products and makes it impossible for one player to lock customers to their products by concealing the source code.
