As you might have seen over on @FediTips , Wanderer is a trail-sharing platform for the Fediverse somewhat similar to Strava.
Wanderer is free open source software so you can host your own server if you want, and federated so you can communicate with other servers too.
At the moment Wanderer does require some technical knowledge to create your own server, you can find installation instructions at https://wanderer.to/run/installation/quick and source at https://github.com/open-wanderer/wanderer
