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.

Open-source builds that already do this

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

Not run yet
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.
