Health, home and travel decision
AllTrails Plus
A competent developer can build a usable trail search + map + GPX recording web app in about a week, but the full paid AllTrails product (offline maps, live navigation, curated partner deals, mobile polish, and proprietary datasets) would be hard to match without more time and licensing.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Allow users to search trails, view an interactive map with a trail overlay, view trail details (distance, difficulty, estimated time), create or upload a route (GPX), and record/relive an activity summary.
What it still won’t have
- Offline downloadable maps for use without cellular service
- Turn-by-turn live navigation and advanced live tracking features
- Curated deals and partner promotions for premium members
- Mobile-app polish, syncing across devices, and App Store/Play Store ecosystem features
- Any proprietary trail dataset or licensing held by the vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AllTrails-like web app using: Node.js + Express backend, Postgres (PostGIS optionally) for trails and routes, React frontend, Leaflet (or Mapbox GL) for maps, and Docker for deployment. In scope: (1) ingest a modest trail dataset (GeoJSON) into Postgres, (2) implement full-text search endpoints and a trail detail API, (3) interactive map UI showing trails and selected trail detail, (4) GPX import/export and a simple route editor (draw and save), (5) user auth and saved routes/activities, (6) activity recording: capture client-side GPS, upload and store as GeoJSON, and replay on map, (7) deploy to a single VPS or managed cloud instance, include backups and basic logging. Out of scope: offline downloadable map packs, mobile native apps, merchant/partner deals, advanced navigation/turn-by-turn voice. Include basic error handling, validation, and unit/integration tests for APIs.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
