But… maybe you also want to use an Invidious instance that uses googlevideo javascript instead of proxying the videos? So you dont actually suck their resources.
Because Freetube runs on Electron which is Google, and I am not sure how hardened it is, probably just “not bad”.
Do you know any minimal Invidious UI you can run from a Podman/Docker container? Like just the frontend, so that I can use Firefox instead of that. I think having that as a base and adding the freetube features would be great.
