Open Source Philosophy

Free, transparent software with no strings attached. This is how we build technology for your business.

What is open source software?

Open source software is software whose source code is publicly available. Anyone can study it, modify it, and distribute it freely. It is not just about saving on licenses: it is a collaborative development model where thousands of companies and developers contribute to creating professional-quality tools.

Projects like Linux, PostgreSQL, Odoo, and Proxmox demonstrate that free software competes with - and often surpasses - proprietary alternatives in functionality, security, and performance.

Advantages for SMEs

Technology independence

No vendor lock-in. You choose your provider, your update pace, and your roadmap.

No licenses

Zero license cost. Invest in implementation and training, not in usage permissions.

Transparency

Auditable code. You know exactly what your software does, no black boxes or surprises.

Global community

Thousands of developers and companies contribute to continuously improving the software.
