The verdict: can you vibe code AllTrails?
Build a personal offline-first trail tracker subset with Expo and Supabase, but keep paying for AllTrails to access its massive proprietary trail database and offline global topo library.
Replicating AllTrails as a solo developer using AI coding agents is a serious undertaking primarily because of geospatial data management and offline vector map rendering. While an AI agent can quickly scaffold a Next.js web directory and an Expo mobile shell with a Supabase database, rendering multi-layered topographic maps that work reliably without cell service requires complex MBTiles packaging and native Mapbox bindings. Furthermore, your personal clone will be completely empty of the 400,000+ curated global trail guides and user reviews that give the real app its actual utility.
Estimated effort: 4-6 weeks of focused development and debugging
What you can't replicate
- The crowdsourced database of millions of real user reviews, trail conditions, and photos
- The proprietary catalog of hand-verified global trail geometry maps
- Partnerships with major outdoor brands and park authorities

Build guide
01Scaffold Monorepo and Database Schema
Initialize a TypeScript monorepo containing a Next.js web app and an Expo mobile app. Set up Supabase with PostgreSQL and enable the PostGIS extension for spatial querying.
Set up a monorepo with a Next.js web dashboard and an Expo React Native mobile app using TypeScript and Tailwind CSS. Connect Supabase as the primary database provider. Write the SQL migration script for Supabase using the PostGIS extension to create a 'trails' table with a geometry (LineString/Polygon) column, difficulty level, length, elevation gain, and a 'activities' table to store recorded GPS breadcrumb tracks. Ensure proper spatial indexing (GIST index) on the trail geometry column for fast bounding-box queries.02Implement Trail Discovery and Spatial Search API
Build backend endpoints and UI components to search and filter trails based on geographic bounding box, distance, and difficulty ratings.
Implement a Next.js API route that queries Supabase/PostGIS for trails within a given geographic bounding box or radius from a user's center coordinate. Add filtering parameters for difficulty ('easy', 'moderate', 'hard'), minimum/maximum length, and search query keywords. On the frontend, build a discovery screen featuring a list of top local trails with elevation profiles, star ratings, and distance metrics derived from the database.03Integrate Interactive Maps and Custom Route Builder
Embed Mapbox GL within both the web app and Expo mobile app to render topographic maps and allow users to draw custom routes.
Integrate Mapbox GL JS into the Next.js web app and react-native-mapbox-maps into the Expo mobile app. Build a custom route creation tool where users can click points on the map to draw a polyline connecting trailheads. Calculate total distance and cumulative elevation gain on the fly using turf.js or PostGIS spatial functions, and allow saving the custom route directly to the user's profile.04Build GPS Activity Recorder and Background Tracking
Implement location tracking in the Expo mobile app to record user hikes in real-time, storing breadcrumbs locally and syncing them online.
Build a GPS activity recording screen in the Expo mobile app using expo-location. Configure background location permissions and foreground services to track user coordinates continuously during an active hike. Store recorded breadcrumbs locally in an SQLite database using Expo SQLite to ensure persistence if cellular connection drops. Display the live path on the Mapbox view with elapsed time, distance traveled, and current pace.05Add Offline Map Package Download Capability
Enable users to download bounding-box map tiles and trail geometry packages for offline usage when venturing into remote areas.
Implement an offline map download manager in the Expo mobile app. Allow users to select a geographic region or trail area to download vector tile packages and trail metadata JSON into local device storage using expo-file-system. Configure the Mapbox offline manager to load tiles from the local disk cache when network connectivity is unavailable, displaying an offline indicator status in the UI.06Polish UI, Community Reviews, and Final Testing
Add user reviews, star ratings, photo upload handling, and perform comprehensive end-to-end testing across web and mobile clients.
Build a community review and photo upload subsystem. Implement a form allowing users to submit star ratings, written reviews, and upload photos linked to specific trails, storing images in Supabase Storage. Add polish to the mobile navigation tabs ('Explore', 'Saved', 'Record', 'Profile') and write comprehensive integration tests for the trail search and GPS recording loops.
