A really cool app is wanderer https://github.com/Flomp/wanderer
It's not directly what you asked but it is cool
To me, it's cooler than komoot and outdooractive but it's not "social" consumer ready
Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.
OpenStreetMap is a map of the world, created by people like you and free to use under an open license.
Join OpenStreetMap and start mapping: https://www.openstreetmap.org/.
There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.

Also it superimposes over komoot, bikerouter, etc with a firwfox plugin
A public instance with a community would be what I would be looking for. Thank you!
Just a quick note, komoot uses OSM, maybe not in its mobile apps where system apis available, but you should see the Map data © OpenStreetMap contributors
text on the bottom right corner of the map, example link to the map: https://www.komoot.com/discover/Location/@48.0186032,16.9920158
I never used komoot, and I'm not an hiking guy, so I don't have experience with alternatives
bikerouter.de has some pretty cool routing options.
Have a look at RouteYou and Wikiloc
I'm not familiar with Komoot, can you share what features you're looking for?
If it's similar to what I'm thinking of, these two might be relevant on the selfhosted side

https://github.com/samr1/fittrackee
The second one might be getting social features?
For apps, I think this is what people recommended for hikes/trails
Sorry for being unprecise, I added some more context to the actual post.
