security.yml, lint-prettier.yml and the release workflows still ran actions built for Node 20 (checkout and setup-node v4, github-script v7, the docker actions v3/v5, create-github-app-token v1), which GitHub now forces onto Node 24 with a deprecation warning on every run. They move to the Node 24 majors test.yml already uses (download-artifact to v7, since v6 is still Node 20). Third-party actions, several of which hold the Docker Hub and GitHub App secrets, are pinned by commit with the tag in a comment. ubuntu-latest moves to a new Ubuntu release on 10-19, so every job names ubuntu-24.04 and the switch happens in a PR. Every setup-node reads .nvmrc; publish-plugin-sdk leaves 22, which it ran under a comment claiming it matched the server. security.yml gains an npm audit job over the lockfile, on PRs and pushes into dev as well as main. It covers what the image installs and the plugin SDK, takes seconds, and would have flagged the brace-expansion regression the ORM squash brought in the day it landed. Scout keeps its image scan on main. Neither becomes a required check: a CVE published overnight would turn every open PR red, including the ones that cannot fix it. The scout job now also skips PRs into dev, which the trigger change would otherwise hand it. .github/dependabot.yml adds weekly version updates into dev for the root workspace, plugin-sdk, the actions and the Docker base images, minor and patch grouped per ecosystem, majors one PR each. The Node major in the Dockerfile is left to a hand-made change together with .nvmrc.

Most of what follows is an addon an admin switches on or off. Lists, Costs, Documents, Collab, Vacay and Atlas ship on; Journey, Collections, MCP, AI Parsing and AirTrail ship off and are marked below.

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
