"Safe to ship commercially" goes only on what each vendor's published terms say, and every tool page links to them. It isn't legal advice. The engine filter shows tools whose vendor states a plugin, integration or export for that engine. Most other tools export standard files (PNG, FBX, GLB, WAV and so on) that work in any engine.
