TREK review
A broad, free itinerary planner for travelers comfortable managing self-hosted software.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TREK is an open-source travel itinerary planner for individuals and groups who want one place to organize trips. Its scope covers day-by-day plans, drag-and-drop places, interactive maps, reservations, booking confirmations, budgets, packing lists, documents, tasks, attachments, weather forecasts, and shared editing. The product runs on a user-managed server through Docker or Kubernetes and is available across web, iOS, Android, and self-hosted deployments. It fits travelers planning complex trips, families coordinating details, and groups that want control over where their itinerary data is hosted.
Its ecosystem is broader than a basic itinerary tool. TREK connects with OpenStreetMap, Google Places, Google Maps, CoMaps, AirTrail, Immich, Synology Photos, Transitous, Open-Meteo, MCP-compatible clients, and OIDC identity providers. Reservation imports accept EML, PDF, PKPass, HTML, and TXT confirmations, while export and synchronization options include calendar feeds, PDF, GPX, KML, and KMZ. Route optimization can be exported to Google Maps or CoMaps. These connections make TREK suitable for users who value mapping, booking organization, offline access, and links to self-hosted or open services.
The main trade-off is operational responsibility. TREK is self-hosted only, so users need to run and maintain it on their own server rather than sign up for a hosted service. That model suits technically capable travelers, privacy-conscious groups, and organizations that already manage Docker or Kubernetes workloads. It is less suitable for someone seeking a ready-to-use SaaS itinerary app with no server administration. Choose TREK for breadth, collaboration, import options, and control; choose an alternative if hosted convenience is the priority.
