OpenFest 2025 – Celebrate Open Source and Free Culture

OpenFest 2025 returns to Sofia Tech Park on October 18–19, bringing together developers, tech enthusiasts, and open-source advocates from across Bulgaria and Europe. The festival celebrates free software, open data, and collaborative culture through inspiring talks, practical workshops, and community showcases.

This year’s program features a strong lineup of speakers from a wide range of disciplines. Filip Andonov from the Student Aerospace Engineering Club opens the event, followed by sessions from Petar Kirkov on NIS2, CRA, and DORA, Bozhidar Bozhanov on the AI Use & Development Act, and Martin Sotirov with Defining Libre Hardware and a KiCad PCBs workshop. 

Beyond lectures, OpenFest 2025 invites participants to dive into hands-on sessions: building mechanical calculators, exploring retro computers, lockpicking with Tool, soldering with Olimex, BASH scripting fundamentals, and Fritzing for beginners. Creative workshops also take the stage, from Alex Milanov’s Music Tech Jam Session to Afrodita Dobreva’s Speak Geek, blending technology, art, and community spirit.
