While not TecDoc, OpenLEC uses open-source data aggregated from Wikipedia, manufacturer press kits, and community contributions. It is 100% free, fully portable (Java based), and runs on a USB stick. It contains data for vehicles up to 2018.

If the word "free" is the most important part of your search, abandon TecDoc entirely. Use (Light Electronic Catalog).
