KiCad
Open-source electronics design automation suite for schematic capture, PCB layout, libraries and 3D PCB visualization.
OpenSCAD
Script-based solid 3D CAD modeler. Useful for parametric parts, reproducible models and technical designs generated from code.
Cloud, File Sync, Transfer & Collaboration
Nextcloud
Self-hosted content collaboration platform for files, sharing, calendars, contacts, office integration and private cloud workflows.
Syncthing
Continuous file synchronization between two or more computers. Good for peer-to-peer sync without depending on a central third-party cloud.
FileZilla
