`last_seen_at` has been written on every request since sessions existed —
throttled to once a minute, deliberately, so a list could one day say
"denne enhed, lige nu" — and nothing has ever read it. The store even had
ListSessions. What was missing was two routes and a panel.
GET /auth/sessions lists them, most recently used first, with the current
one marked so nobody has to work out which row is the browser they are
reading it in. DELETE /auth/sessions/{id} ends one. Ending the current
session is allowed and is simply logging out: refusing it would be a rule
with no reason behind it, and somebody clearing every device wants this
one gone too.
Both are behind requireSession rather than the ambient auth, the same as
the API tokens. A leaked token that could list its owner's devices and end
their sessions turns a theft into a lockout.
The delete is scoped in the statement rather than checked and then run.
An id read in one step and deleted in the next is a window, and the whole
reason somebody is on this screen is that they think another person is in
their account.
The device names are a handful of substring tests, not a parsing library.
The question this answers is "is one of these me?", and for that a wrong
guess between two Chromium forks costs nothing while a dependency that has
to be kept current costs something every year. Order is the whole
correctness of it: an iPhone's user agent says Mac OS X, Edge says Chrome,
and Chrome says Safari. The raw string is sent alongside and sits in the
row's title, so anything the summary gets wrong is still visible — and
something that is not a browser at all shows its own name rather than
"Ukendt", because a CalDAV client is a real session.
Times are relative. The question is "was that me, just now?", and an
absolute timestamp makes the reader do the subtraction; past a week it
switches to a date, because "for 23 dage siden" is a number nobody can
place.
The smoke test signs in a second time in a second browser context, ends
that session from the first, and checks the other browser is really signed
out — and that this one is not.

verdande
Self-hosted tasks and projects, shared with the people you share the work with.
One binary, SQLite inside it, deployed as a Rune in Yggdrasil Panel.
Verdande is one of the three Norns — the one who spins that which is becoming. Not what has been, and not what is fated to be: the thing you are in the middle of. Which is what a to-do list is.
Status
All six phases are built. See What works today for what is tested and what is not.
Documentation: docs/, built with Material for MkDocs.
Why this exists
Todoist Pro, self-hosted, on your own hardware, with your own data — and with the integrations that a hosted product will not build for you: a real CalDAV server, a mail-to-task address, and an MCP endpoint so Claude can work your task list directly.
What it does
- Quick add that reads what you type.
betal moms i morgen kl 10 p1 #Firma @regnskabbecomes a task called "betal moms", due tomorrow at 10:00, priority 1, in Firma, labelled regnskab. Danish and English, mixed freely in one line. - Projects, sections, sub-tasks, labels, saved filters. List, board and calendar views, and foldable groups over the projects in the sidebar.
- Drag where it means something. Reorder a list or a board, file a project under a group, drop a task on another project, or drop it on another day.
- Sharing. Internal users are created by an admin; anyone else joins through an invite link sent to their email. Owner, editor and viewer roles.
- Live sync. A change made by somebody else appears without a refresh.
- Recurring tasks as RRULE (RFC 5545), reminders, comments and attachments.
- Standards, not homegrown formats. iCalendar and CalDAV, ICS feeds, OAuth2 with PKCE, OpenAPI 3.1, MCP, Web Push, Argon2id.
- A PWA that works on a phone, installable, with swipe gestures and offline reading of what it has already cached.
What works today
Every phase in the plan is built. You can install it, add tasks by typing a sentence, share projects, watch somebody else's changes appear live, set repeating chores and reminders, save filters, import your Todoist account, sync two-way with Apple Reminders, forward mail into it, and add it to Claude as a connector.

Not finished: Web Push, the AI providers and the Gmail API calls are implemented against their specifications and have only ever been exercised there, not against live services. Everything else has an interface: opening a task shows its description, sub-tasks, comments, files and reminders, and the settings pages cover the account, notifications, integrations, AI, API tokens, import, export and templates.
Search finds grøn when you type gron, because Unicode does not consider ø an
accented o and a Danish-first app that cannot do this is broken for its own users.
What it looks like

| Board view — one column per section. | The light theme. |
Regenerate these with go run ./tools/shots against a running instance.
Running it
As a Rune in Yggdrasil Panel
verdande is built to be deployed as a Rune in Yggdrasil Panel — that is its home, and the manifest ships in this repository. It runs anywhere Docker does as well.
- Runes → Carve a rune (upload) and pick
rune/verdande.yaml. - Create a server from it.
- Set Public address to the address you will actually reach it on. verdande
cannot work this out for itself — the host port is not chosen until the server
exists — and invite links, password resets and calendar feeds are all built from
it.
{{PUBLIC_URL}}is the default and is usually right. - Point the SMTP settings at your mail server. Leave the host blank and verdande shows invite links in the app instead of emailing them, which is fine for a single user and no use at all for sharing.
- Start it, open the URL, create the first account. That account is the admin.
With Docker directly
docker run -d --name verdande \
-p 8080:8080 \
-v verdande-data:/data \
-e VERDANDE_BASE_URL=https://todo.example.dk \
ghcr.io/kristianwind/verdande:latest
From source
go run ./cmd/verdande
Listens on :8080 and puts its data in /data, so for local work set
VERDANDE_DATA_DIR somewhere writable:
VERDANDE_DATA_DIR=./data VERDANDE_DEV=true go run ./cmd/verdande
A plain go build produces the API without the web interface — the frontend is
embedded only when built with -tags embedweb, so a clean checkout compiles
without a Node toolchain installed.
Configuration
Everything is an environment variable; there is no config file. A Rune has nowhere to put one that the operator would ever see.
| Variable | Default | What it does |
|---|---|---|
VERDANDE_BASE_URL |
http://localhost:8080 |
The public address. Invite links, password resets and ICS feeds are built from it. |
VERDANDE_ADDR |
:8080 |
Listen address. |
VERDANDE_DATA_DIR |
/data |
Database, uploaded files and backups. |
VERDANDE_SESSION_TTL |
720h |
How long a login lasts. |
VERDANDE_INVITE_TTL |
168h |
How long an invite link stays valid. |
VERDANDE_RESET_TTL |
1h |
How long a password-reset link stays valid. |
VERDANDE_SMTP_HOST |
— | Blank disables outbound mail; invite links are shown in the app instead. |
VERDANDE_SMTP_PORT |
587 |
|
VERDANDE_SMTP_USER |
— | |
VERDANDE_SMTP_PASS |
— | |
VERDANDE_SMTP_FROM |
verdande@localhost |
Sender address. |
VERDANDE_SMTP_STARTTLS |
true unless port 465 |
Port 465 is TLS from the first byte; everything else negotiates. |
VERDANDE_SMTP_INSECURE |
false |
Skip certificate verification. For a self-signed internal mail server, and nothing else. |
VERDANDE_GMAIL_CLIENT_ID |
— | OAuth client from Google Cloud, if anyone will connect a mailbox. |
VERDANDE_GMAIL_CLIENT_SECRET |
— | |
VERDANDE_UPDATE_CHECK |
false |
Ask GitHub whether a newer release exists. Sends nothing about your instance. |
VERDANDE_DEV |
false |
Human-readable logs at debug level. |
What lives in /data
/data
├── verdande.db SQLite, WAL mode
├── files/ attachments
└── backups/ nightly snapshots, 14 days
Back up the whole directory. If you copy verdande.db on its own while the server
is running you will get a database missing its most recent writes — the -wal file
is part of it.
Roadmap
- MVP — auth, projects, sections, tasks, sub-tasks, priorities, due dates, quick add, Today and Upcoming, search, keyboard shortcuts. (done)
- Sharing — invites, roles, assignees, comments, attachments, activity log, realtime sync, notifications. (done)
- Pro parity — recurring tasks, reminders, filter queries, board and calendar views, durations, ICS feeds, templates, automatic backups. (done)
- Import/export — Todoist CSV and official export in, CSV/JSON/ICS out. (done)
- Integrations — CalDAV server, mail-to-task, Gmail, MCP server for Claude, and a provider-agnostic AI layer that also talks to a local model. (done)
- Publication — documentation, landing page, open-source scaffolding. (done)
Development
go test ./... # everything
go test -race ./... # what CI runs
gofmt -l . # must print nothing
Working on the interface means two processes: the API on 8080, and Vite on 5173
proxying /api to it, so the session cookie stays first-party exactly as it is in
production.
VERDANDE_DATA_DIR=./data VERDANDE_DEV=true go run ./cmd/verdande
cd web && npm install && npm run dev
To run the whole thing as one binary the way it ships:
cd web && npm run build && cd .. && cp -r web/build cmd/verdande/webbuild && go build -tags embedweb -o verdande ./cmd/verdande
Commits follow Conventional Commits; releases are semver tags, which build and publish the image.
Non-goals
Karma and points. Team workspaces and organisations. Native apps. Mail integrations beyond Gmail and the forwarding address. Languages beyond Danish and English. A sync protocol of its own — CalDAV and the REST API are the sync.
