From the large-screen review (code findings H1, M1, M2, M3, M4, M7, L1, L3, L4, L6, L7): - The size class is one value in JavaScript (hooks/sizeClass.ts) and the stylesheet follows it: MobileShell writes it to the shell as data-size, the wide:/split: variants and mobile.css key on that instead of media queries of their own. A window that only grows shorter at the same width while a field has focus is Android's soft keyboard, not a new window, so the rail, the form sheets and the panes no longer fold away (and take the focused field with them) while one types. - The large-screen layout is the app's only. In a browser the touch shell is the phone's below 768px and stays compact there, as before this branch. - Shortcuts are the app's only, so a browser keeps Ctrl+1 and Alt+Left. The command key is the platform's own (Cmd on Apple, Ctrl elsewhere), digits are matched by the key's place as well (AZERTY), and nothing runs while a sheet or another modal dialog is open: the page listens to nothing and the app is handed no key commands, so Cmd+[ can no longer drop an unsaved form. - Inside a trip Cmd+N belongs to the trip shell and creates what the tab on show creates, named after it. - Inside the touch shell the desktop navbar of the few PageShell routes is hidden and --nav-h is 0. - The rail comes before the page in the DOM, so a keyboard reaches it first. - The phone's deep day colour for a journey card without a photo stays the phone's; the desktop and shared timelines keep their faint wash. Its card is opaque, a suggestion included, so the map's names do not read through. - The trip widget's iPad mini layout keys on the iPad mini's width alone. - The trip dock gets the scroll-edge strip and the denser dock glass the global dock has. - Duplicate test id FE-MOB-PANES-016 renumbered.
Every part of your trip. One app you own.
TREK has grown from a travel planner into a whole ecosystem for trips: plan together in real time on a live map, build hikes, tours and road trips, keep bookings and shared costs in order, pack, write the journal, lay out the photo book and hand the busy work to the built-in AI. Self-hosted, on the web, on your phone and offline.

Powered by dataforest cloud
Every TREK installation in the world searches through servers that dataforest cloud sponsors.
The place index with over 88 million places, the address search in every TREK language and the planet-wide routing all run on dataforest cloud in Frankfurt, Germany, free of charge for everyone who self-hosts TREK. Without this sponsorship, these services would not exist in this form.
Thank you, dataforest, for backing open source this generously. 💚
Looking for a server for your own TREK? dataforest cloud is where TREK's own services live.
AI usage
We use LLM-assisted coding tools across parts of this codebase. Nothing ships that a maintainer has not read and understood: every change goes through a pull request, is reviewed and tested, and has a human who can answer for it. "The AI wrote that" is not an answer any of us would accept from ourselves.
See How we use AI in TREK for the details.
Get started in 30 seconds
ENCRYPTION_KEY=$(openssl rand -hex 32) docker run -d --name trek -p 3000:3000 \
-e ENCRYPTION_KEY=$ENCRYPTION_KEY \
-e COOKIE_SECURE=false \
-v ./data:/app/data -v ./uploads:/app/uploads mauriceboe/trek
Open http://localhost:3000, or http://<server-ip>:3000 from another machine. On first boot TREK seeds an admin account — if you set ADMIN_EMAIL/ADMIN_PASSWORD those are used, otherwise the credentials are printed to the container log (docker logs trek).
COOKIE_SECURE=false is only for trying TREK over plain HTTP: without it the browser drops the session cookie and the login does not stick. Once TREK sits behind HTTPS (see Reverse Proxy), remove it.
Tip
No server yet? TREK's own public services run on dataforest cloud, our infrastructure sponsor. A small seed is plenty for a TREK instance and is ready within a minute.
Tech stack
Real-time sync via WebSocket (ws). Backend on NestJS 11. State with Zustand. Auth via JWT + OAuth 2.1 + OIDC + Passkeys (WebAuthn) + TOTP MFA. Weather via Open-Meteo (no key required). Maps with Leaflet and Mapbox GL.
Docker Compose (production)
The repository ships a ready-to-use docker-compose.yml
with secure defaults and every option documented inline. Download it, then:
docker compose up -d
See Install with Docker Compose for the full walkthrough.
Helm (Kubernetes)
helm repo add trek https://chart.liketrek.com
helm repo update
helm install trek trek/trek
See charts/README.md for values.
Install as App (PWA)
TREK works as a Progressive Web App, and the TREK Travel Planner app for iPhone, iPad and Android connects to the same server (Native Apps). To install the web app instead:
- Open TREK in the browser (HTTPS required)
- iOS: Share ▸ Add to Home Screen
- Android: Menu ▸ Install app (or Add to Home Screen)
TREK then launches fullscreen with its own icon, just like a native app.
Updating
See Updating — Docker Compose, Docker run, Helm, Portainer, Unraid and Proxmox, plus the encryption-key note.
Reverse Proxy
For production, put TREK behind a TLS-terminating reverse proxy. TREK uses WebSockets for real-time sync, so the proxy must support WebSocket upgrades on /ws.
If you use the MCP addon, the proxy must also pass the Mcp-Session-Id header through in both directions on /mcp — Nginx and Caddy do this by default, but a proxy that strips it makes every tool call open a new session instead of reusing one. See the Reverse Proxy wiki page for details.

Caddy
