Perhaps this has improved, but when I tried it out a few months ago I found that the playback for continuous recording was extremely basic and didn't have features like easy-to-use variable speed scrub to make it practical to search for things. I might try it out again today because I would like to go to something that doesn't have to run on Windows, but my use case is more around continuous recording with around a month of history than event detection.

Space management for rolling retention is also a new feature in Frigate and very basic, I don't think it has a way to do different retention policies by camera group and alarm.
