## What it is
TREK is a self-hosted, real-time collaborative travel and trip planner web application built with TypeScript. It offers interactive maps, day-by-day planning, budgets with expense splitting, packing lists, a travel journal, SSO, PWA support, and AI features, deployable via Docker.

## Use cases
- plan a multi-day trip itinerary with routes and points of interest on an interactive map
- collaborate with friends or family on a shared travel plan in real time
- track trip budgets and split expenses among travel companions
- create and check off packing lists before a trip
- keep a travel journal of a journey
- self-host a private alternative to Wanderlog or TripIt
- install as a PWA to access trip plans on mobile

## When to choose
- you want full control over your travel data by self-hosting on your own server
- you need real-time collaborative trip planning with maps, budgets, and packing lists in one tool
- you want an open-source alternative to Wanderlog or TripIt
- you need SSO support and PWA access for a travel planning app

## When to avoid
- you need a hosted, zero-setup travel planner without managing your own server
- you only need simple flight or hotel booking management rather than full trip planning
- you require native mobile apps rather than a web/PWA experience
- you cannot accept AGPL-3.0 licensing constraints for your use case
