wanderer is a self-hosted trail database and route planner connected to the fediverse, a bit like a Komoot or AllTrails you run yourself. Starting today there’s a native app for it, in public beta.

What the app does

• Find trails: search your instance and any instances it federates with. Filter by category, difficulty, distance or elevation.
• Plan routes: tap anchors on the map and the router connects them along paths, for hiking or one of four bike profiles.
• Record: GPS tracking with live distance, elevation gain, speed and moving time. It keeps recording in the background and needs no network.
• Offline maps: download whole map regions and trails before you leave.
• Turn-by-turn navigation: works offline too, and records your track while you navigate.

For admins: what your instance needs

Please read the guide on how to make your instance comaptible with the app: https://openwanderer.com/run/backend-configuration/mobile-app/

It’s a beta. Do not rely on the app alone for navigation! Always carry a backup map (digital or physical). The goal is full parity with the web UI, but some things are still web-only for now. There’s a full comparison here: https://wanderer.to/app/what-works-where

Hi c/selfhosted,

I just released wanderer v0.17.0, which brings full federation support to the project.

E.g.: https://lemmy.world/u/[email protected]

For anyone new to it: wanderer is a self-hosted platform for managing hiking, biking, or running trails. You can upload or draw GPS tracks, organize them into lists, add photos, metadata, waypoints, and summit logs. It’s open source and designed for people who want full control over their outdoor data, with a clean UI and no third-party dependencies.

What’s new in v0.17.0

This release adds support for ActivityPub, meaning instances of wanderer can now talk to each other—and to the wider fediverse. Here’s what that enables:

• Follow users across instances When you follow someone, any new trails or lists they upload will show up in your feed automatically.
• Like and comment on trails, even across servers.
• Mentions You can mention other users in trail descriptions, comments, or summit logs, and they’ll be notified—regardless of which instance they’re on.
• Summit logs from others Other users can now log their own visits to your public trails with GPS data and photos.
• Cross-instance trail sharing Public trails can be shared with users on other instances.

If you’re not interested in federation, that’s fine too. wanderer still works completely standalone—federation only kicks in when you start interacting with other instances.
