A self-hosted, real-time collaborative travel planner — with maps, budgets, packing lists, a journal, and AI built in.

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=$(openssl rand -hex 32) docker run -d -p 3000:3000 \
-e ENCRYPTION_KEY=$ENCRYPTION_KEY \
-v ./data:/app/data -v ./uploads:/app/uploads mauriceboe/trek
Open http://localhost:3000. 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).
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 — no App Store needed.
- 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
trek.yourdomain.com {

Caddy handles TLS and WebSockets automatically.

At-rest encryption key for stored secrets (API keys, MFA, SMTP, OIDC). Recommended: generate with: openssl rand -hex 32. If unset, falls back to data/.jwt_secret (existing installs) or auto-generates a key (fresh installs).
Internal server port (must match the container port mapping above).

Where the in-app Help pages (/help) read their content from. Leave empty: the container ships the wiki at /app/wiki and finds it automatically. Only set this to serve your own docs from a mounted path. If the path does not exist, Help falls back to fetching the public GitHub wiki (needs outbound network, and tracks the latest release rather than your version).
Default language shown on the login page for users with no saved preference. Browser/OS language is auto-detected first; this is the fallback when no match is found. Supported: de, en, es, fr, hu, nl, br, cs, pl, ru, zh, zh-TW, it, ar.
- Default

- Value
- en
Comma-separated origins allowed for CORS and used as base URL in email notification links (e.g. https://trek.example.com).
Public base URL of this instance (e.g. https://trek.example.com). Required when OIDC is enabled — must match the redirect URI registered with your IdP. Also used as base URL for email notification links.
Optional. When true: HTTPS redirect, HSTS header, CSP upgrade-insecure-requests, and secure cookies. Only useful behind a TLS-terminating proxy. Requires TRUST_PROXY.
- Default
- false
- Value
- false
When true: adds includeSubDomains to the HSTS header, extending HTTPS enforcement to all subdomains. Only effective when HSTS is active (FORCE_HTTPS=true or NODE_ENV=production). Leave false if you run other services on sibling subdomains over plain HTTP.
- Default
- false
- Value
- false
Auto-derived (true in production or when FORCE_HTTPS=true). Set to false to force session cookies over plain HTTP. Not recommended for production.
- Default
- true
- Value
- true
Trusted proxy hops for X-Forwarded-For/X-Forwarded-Proto. Defaults to 1 in production; off in development unless set. Required for FORCE_HTTPS.

How long a login session stays valid when 'Remember me' is unchecked (the default): trek_session JWT exp + a browser-session cookie cleared when the browser closes. Accepts 1h, 12h, 7d, 30d, 90d. Defaults to 24h.
- Default
- 24h
- Value

- Default
- 30d
- Value
- 30d
Email for the first admin account created on initial boot. Has no effect once any user exists.
- Default
- admin@trek.local
- Value
- admin@trek.local
Password for the first admin account created on initial boot. If omitted a random password is generated and printed to the server log. Has no effect once any user exists.
OpenID Connect provider URL (e.g. https://auth.example.com).
OIDC client ID registered with your identity provider.
OIDC client secret registered with your identity provider.
Label shown on the SSO login button.
- Default

Set to true to force SSO-only mode. Disables password login and password registration — overrides the granular toggles in Admin > Settings and cannot be changed at runtime. First SSO login becomes admin.
- Default
- false
- Value
- false
OIDC claim used to identify admin users (e.g. groups).
Value of the OIDC claim that grants admin role (e.g. app-trek-admins).
Space-separated OIDC scopes to request. Fully overrides the default — always include openid email profile plus any extra scopes you need (e.g. add groups when using OIDC_ADMIN_CLAIM).
- Default
- openid email profile
- Value
- openid email profile
Override the auto-constructed OIDC discovery endpoint. Useful for providers with a non-standard path (e.g. Authentik).

Optional Unsplash Access Key for trip-cover and place-image search. Without one, TREK uses Unsplash's unauthenticated endpoint, which some datacenter/VPS IPs are blocked from. Get a free key at unsplash.com/developers. Can also be set per-admin in Admin > Settings; this env var overrides that.
