TREK Wiki

TREK is a self-hosted, real-time collaborative travel planner licensed under AGPL-3.0.

Features

Planning

• Drag & Drop Planner: organize places into day plans with reordering and cross-day moves
• Interactive Map: Leaflet map with photo markers, clustering, route visualization, customizable tile sources, category buttons (plugins can add their own) and a lock that keeps the view where it is
• Place Search: TREK's own place index and OpenStreetMap, asked together, with no API key and no quota; Google or Amap answer only where both come up empty (see TREK Places API)
• Day Notes: notes between a day's stops, each with a title, Markdown text, an icon and a colour
• Route Optimization: auto-optimize place order, draw the day for driving, walking or cycling, leave single stops out of the route, and hand the day to Google Maps or CoMaps (see Route Optimization)
• Weather Forecasts: 16-day forecasts via Open-Meteo (no API key required), historical climate averages as fallback

Travel Management

• Reservations & Bookings: hotels, restaurants, tickets and every other booking with its confirmation code, travelers, costs and files, shown as cards, as a list or on a timeline; flights, trains and cars have their own Transports tab
• Budget Tracking: an expense ledger with who paid and itemised splits, settle-up, receipts (scanned into an expense with Scan receipt when AI Parsing is on), expenses linked to bookings, transports and places, a table view with per person and per day figures, multi-currency support (see Budget Tracking and Currencies)
• Packing Lists: category-based checklists with user assignment, templates, quantities and weights, progress tracking, and print, PDF, Markdown and CSV export (see Packing Lists)
• Document Manager: attach documents, tickets, and PDFs to trips, places, or reservations (up to 50 MB per file by default, set with FILE_UPLOAD_LIMIT_MB)
• Document Sync (admin-enabled): keep a trip's documents in step with a self-hosted Paperless-ngx, Papra, Nextcloud, OpenCloud or Synology NAS, in both directions, under one connection the trip owner sets up for every member (see Document Sync)
• PDF Export: export complete trip plans as PDF with cover page, images, and notes, or only your own activities with My plan as PDF (see PDF Export)

Collaboration

• Real-Time Sync: WebSocket-based live sync; changes appear instantly for all connected users
• Multi-User: invite members with role-based access
• Invite Links: registration links with configurable max uses (1 to 5, or unlimited) and expiry
• OIDC SSO: sign in with Google, Apple, Authentik, Keycloak, or any OIDC provider
• Two-Factor Authentication: TOTP-based 2FA with QR code setup
• Passkeys (admin-enabled): passwordless WebAuthn sign-in with Touch ID, Windows Hello, Android screen lock, or a hardware key; owning one also satisfies the require-2FA policy (see Passkeys)
• Public Share Links: share a read-only view of any trip, in full, as Travel & stays only or Without photos (see Public Share Links)
• Notifications: in-app, email, webhook and ntfy, and Web Push to a phone or computer even while TREK is closed (see Notifications)

Addons (admin-toggleable)

• Lists: packing lists and to-dos with templates, member assignments, optional bag tracking
• Costs: expense tracker with category breakdown, splits, multi-currency
• Documents: file manager for trips, places, and reservations
• Collab: group chat, shared notes, polls, day-by-day attendance
• Road trip: plan a trip as one continuous drive, with search along the route, driving limits, daily travel times and avoidance of toll roads, motorways and ferries (see Road Trip)
• Vacay: personal vacation day planner with calendar view, public holidays, company holidays (also as half days), and carry-over tracking
• Atlas: interactive world map with visited countries and regions, bucket list (countries or regions), travel stats, continent breakdown
• Collections: a personal place library that saves places across trips into named lists, copies them into any trip, and shares them with per-member roles (see Collections)
• Journey: magazine-style travel journal with entries, drafts, photos (via Immich/Synology Photos) shown on the journey's map when geotagged, and moods
• Naver List Import: import places from shared Naver Maps lists
• MCP: expose TREK to AI assistants via the Model Context Protocol (OAuth 2.1)
• AirTrail: sync flights from your self-hosted AirTrail instance into trips
• Dawarich: read the stays and routes your self-hosted Dawarich instance recorded, offered as suggestions you confirm; nothing is written back (see Dawarich)
• AI Parsing: LLM fallback that extracts bookings from confirmation files KDE Itinerary cannot read, and, with a model that reads images, from photos and scanned PDFs and receipts (see AI-Booking-Import)

Dashboard widgets (currency converter and timezone clock) are per-user preferences, not an admin-toggleable addon; see Dashboard-Widgets.

The full addon table, with type and per-addon notes, lives in Addons-Overview.

Plugins

• Sandboxed Plugin Runtime: third-party plugins run in a forked child process with permission-gated RPC, install-time manifest and signature checks, and an egress allowlist (see Plugins)
• Plugin SDK: build and publish plugins with the trek-plugin-sdk npm package, with dev server, preflight, signing and submit (see Plugin-Development)

AI / MCP Integration

• MCP Server: built-in Model Context Protocol server with OAuth 2.1 authentication
• 300+ Tools: create trips, plan itineraries, manage budgets, upload files, search places near a point, send messages, and more
• 30 Resources: read-only trek:// URIs for trips, days, places, budget, packing, journeys, and more
• 35 OAuth Scopes: granular permissions across 17 permission groups
• Pre-built Prompts: trip-summary, packing-list, and budget-overview context loaders

Help

• Help Center: the ? in the navbar opens guides for the screen you are on, with a picture of every step and search across guides and the wiki, in every language TREK speaks (see Help Center)
• In-App Help: the whole wiki, bundled with your install and read inside TREK at /help (see In-App Help)

Admin

• User management, invite links, packing templates, global categories
• Addon management, API key storage with a daily limit for Google calls, scheduled auto-backups
• Notification defaults: each event and channel on, off or blocked for every user (see Notifications)
• System notices for onboarding and announcements, including a release notes notice every user sees once after each update (see Admin-GitHub-Releases)

Admin: Most configuration lives in the Admin Panel. On first boot TREK seeds an admin account automatically: credentials come from ADMIN_EMAIL / ADMIN_PASSWORD if set, otherwise a random password is printed to the container log.
