TREK

TREK is a self-hosted, open-source travel planner designed to give users full ownership and control over their travel itineraries and related data. Unlike mainstream travel planning platforms that store sensitive information on third-party servers and often restrict key features behind subscription tiers, TREK keeps all user data local and accessible only to those running the software on their own infrastructure. This approach addresses privacy concerns and eliminates the risk of losing itineraries due to service shutdowns or policy changes.

The platform offers a drag-and-drop day planner interface, allowing travelers to organize places into daily schedules and easily rearrange them. Each itinerary entry is linked to an interactive map, with support for both Leaflet and Mapbox GL—enabling features like 3D buildings and terrain visualization. TREK supports place search through two methods: users can connect a Google Places API key for access to photos, ratings, and opening hours, or use OpenStreetMap for free, accountless search. It also handles data import from shared Google Maps and Naver Maps lists, as well as GPX, KML/KMZ, and GeoJSON files, streamlining the transfer of plans from other tools or GPS devices.

Beyond itinerary management, TREK incorporates budget tracking, packing lists, a travel journal, and AI-powered trip planning. Route optimization automatically sorts stops within a day and can send the optimized route to Google Maps for navigation. The tool provides a 16-day weather forecast via Open-Meteo without requiring an API key, and supplements this with historical climate data for broader planning. Real-time collaboration is built in, allowing multiple users to edit and view changes simultaneously without relying on external cloud services or subscriptions.

Accessibility is enhanced through Progressive Web App support, enabling installation directly from a browser on mobile devices and making the platform usable for non-technical users. Once deployed, TREK includes its complete feature set without recurring subscription fees, positioning it as a comprehensive, privacy-focused alternative to commercial trip planning solutions.
