I was recently looking into this myself, and I saw someone recommend FileFlows, but it was recommended for ease of setup/use, not because it’s open source. Figured I’d mention it, but note that I haven’t had a chance to check it out yet.

I’m interested in knowing this too

There isn’t anything else I’ve found beyond those two that is adaptive quite like those. From what I’ve seen, you’ll have to give up a lot.

Unlike Tdarr though, Unmanic does have a proper open source license. If you take that to it’s logical conclusion, any freemium options are a bit optional.

I wonder if this post has anything to do with the unmanic API outage earlier today, lol. I was pulling my hair out trying to figure out what I’d done wrong until I finally convinced myself there must be a cloud-side outage impacting the plugin browser. By the time I figured it out they came back online and the plugins were browsable again, but I lost hours over this stupid problem.

Today’s outage perfectly illustrated why we choose to self-host in the first place. I too would love to see a completely self-contained foss solution for this service. Some clever shell scripting is probably all you really need to perform automated ffmpeg calls, but individually containerized services are clearly what we all prefer. I do wish I had more time to code…

Couple of days ago ‘honey I shrunk the vids’ was posted here, a very lightweight tdarr alternative. piefed.ca/…/honey-i-shrunk-the-vids-mr-universe-e…

But I haven’t tried it - I’m not sure if it’s perhaps gui-only, and it seems to be AI coded to a certain degree, so YMMV.

I have only tried this for small files but it may be helpful for others: github.com/JMS1717/8mb.local

That looks pretty neat. Not what I’m looking for but would be handy for other projects.
