I made wanderer - a self-hosted trail and GPS track database
Over the last two months, I developed wanderer. It is a self-hosted alternative to sites like alltrails.com or in other words a self-hosted trail database. It started out more as a small hobby project to teach myself some new technologies but in the end, I decided to develop it into a fully-fledged application.
Core Features:
Manage your trails
Extensive map integration and visualization
Share trails with other people and explore theirs
Advanced filter and search functionality
Create custom lists to organize your trails further
I think you might misunderstand what wanderer does. It is not a maps service like Open Street Maps. It's simply a database in which you can store your GPS tracks. So the workflow would look like this: you are in the woods and record your track (e.g. with osmand) -> you store your track in GPX format -> you upload your track (and any additional info like a description or photos) to wanderer -> before your next adventure you check wanderer to decide what you want to do
Logging trips offline requires background location services. This does not work for a simple website. You would need to program an app for that. While this is a plan somewhere down the line, it's still far away. So currently I would recommend relying on an external app to log your trip and import afterwards.
