pyvideotrans is a free, open-source alternative to Vozo. It can be used without subscription fees — and its source code is open for anyone to inspect, modify and self-host.
Desktop app that transcribes, translates, dubs and re-embeds subtitles in one pass, running the whole chain on your own machine. Its license (GPL-3.0) is a copyleft license: you can use, study and modify it freely, and derivative works must remain open-source under the same terms. Commercial use is allowed.
What switching gets you
No subscription, no per-seat pricing — free forever, for individuals and companies alike.
Your data stays with you: it can run locally or on your own servers, with no vendor lock-in.
The source code is public — auditable, extensible and maintained in the open by its community.
