The web UI signs in with a username and password and holds a session cookie; the TUI was the only client still needing an API key pasted into a config file. It now asks for the same credentials on a form at start. What is kept between runs is the session token, not the password, in session.json under the config directory, mode 0600 and keyed by server URL so one server's token is never offered to another. It resumes on the next start; the server's sessions last 30 days and slide with use. L signs out, which ends the session on the server and deletes the saved one even if the server cannot be reached. The client attaches the cookie by hand instead of using a cookie jar: the server marks it Secure behind https, and a jar drops a Secure cookie it is given over plain http, which would break a local server for no reason. It sends no Authorization header at all, since the server judges a request carrying one on that alone and never falls back to the cookie. Writes go through the server's cross-origin guard, which lets a client that sends neither Origin nor Sec-Fetch-Site through; checked against a real v0.20.1 server for both reads and writes. A 401 from anything means the session is gone (expired, ended from the web UI, or the account disabled), so the TUI returns to the form with the reason, forgets the saved token, and drops what the last session loaded rather than showing it to whoever signs in next. A 403 is a permission and leaves the session alone. The refresh timer is started once, so signing out and in does not leave two running. An account with no password cannot sign in, and the server answers it exactly like a wrong password, so the form's message says a password must be set first. Users created only for API access hit this. Breaking: api_key in config.yaml is no longer used. It is not an error to leave it there; the form says it is ignored. API keys still exist on the server and k in Users still manages them.
terdut-tui
A terminal user interface for terdut-server. Communicates with the server over its REST API.
Written in Go using Bubbletea.
Features
- Incident queue — open incidents with severity, status, assignee and age, auto-refreshing
- Incident actions — acknowledge, assign, snooze, note, resolve and archive
- Timeline — the full history of an incident, system events, pages and notes together
- Alert feed — the raw read-only alerts underneath, each linked to its incident
- Teams — switch between your teams, or see all of them at once
- On-call schedule — visual calendar of who is on duty in a team, assign and remove entries
- Statistics — MTTA and MTTR, plus alert frequency by name, hour and day
- User management — add and remove users, manage API keys, set each user's ntfy topic
Requires terdut-server v0.20.0 or later. The server became team-scoped in v0.12 and this client follows it; earlier servers answer 404 for
/api/teamsand the TUI says so on start. Use terdut-tui v0.9.x with servers before v0.12. Escalation ladders, invites, integrations and the admin settings stay in the server's web UI.
Teams
Everything the server returns is scoped to the teams your key's user belongs
to. The header shows which are on screen, and T steps through all → each of
your teams in turn. With several teams showing, incident and alert rows carry a
Team column.
The schedule is one team's rota, so the Schedule section shows the active team, or with all showing the first team you own. Only a team's owners, and administrators, can change its rota; anyone else gets the reason in the status bar instead of a picker. The picker offers only that team's members, because the server refuses anybody else. Stats are not team-scoped by the server and always cover all your teams.
Administrators are the only users who can create or delete users, or act on someone else's password, topic or API keys. Everyone can manage their own.
Alerts and incidents
The server keeps two objects and this client follows that split:
- An alert is Alertmanager's record — firing or resolved, and read-only here.
- An incident is the work item. It is what you acknowledge, assign, snooze, discuss and resolve, and it is where all the actions live.
Incidents are correlated by the groupKey Alertmanager already computed from your
group_by configuration, so several alerts commonly share one incident.
Two behaviours worth knowing before you press a key:
- Resolving is final. The server treats a manual resolve as terminal: a later occurrence opens a new incident rather than reopening this one, and if the alert underneath never stops firing the incident stays closed. The TUI asks for confirmation before doing it.
- Snooze is the "not now" button. It hides an incident from the default queue without closing it, and expires on its own.
Push notifications
When the server is configured for ntfy, an incident that opens pages whoever is
on call. Each user has their own topic, shown as a column in the Users section
and edited with t. A user with no topic falls back to the server's shared
fallback topic, which carries no Acknowledge button — the topic is shared, so
a button on it would let any subscriber acknowledge as somebody else.
Every delivery lands on the incident's timeline: Notified <user> (triggered)
when ntfy accepted the page, and Notification to <user> failed when it ran out
of retries. That second one is the one to look for when nobody's phone rang.
Installation
Download the latest release binary for your platform from the releases page, or build from source:
go install git.ryuvia.com/niklas/terdut-tui@latest
Configuration
Create ~/.config/terdut-tui/config.yaml:
server_url: https://terdut.example.com
username: niklas # optional, prefills the sign-in form
refresh_interval: 30 # seconds, optional
theme: gruvbox-dark # optional, this is the default
team: Ops # optional, a team name or id to start on; default is all
Signing in
The TUI signs in the way the web UI does: with a user account's username and
password, on a form shown at start. It keeps the server's session, not the
password, in ~/.config/terdut-tui/session.json (readable by you only), so the
next start resumes it. The server's sessions last 30 days and slide with use.
When it has ended, or the account is disabled or the session is ended from the web
UI, the TUI returns to the form and says so. L signs out, which also ends the
session on the server and deletes the saved one.
The account needs a password, since that is what signing in uses. A user
created only for API access has none and cannot sign in: the server answers it
exactly like a wrong password. Set one in the web UI, or have an administrator
press p on that user in Users. Too many failed attempts are rate limited by
the server for a few minutes.
Upgrading from v0.10.0 and earlier:
api_keyinconfig.yamlis no longer used. Remove it and sign in. API keys still exist on the server, andkin Users still manages them, for whatever else uses them.
Themes
Two themes ship with the client: gruvbox-dark (the default) and
gruvbox-light. Both colour foregrounds only — the terminal supplies the
background — so pick the one that matches the background you already run.
To make your own, drop a file in ~/.config/terdut-tui/themes/ and name it in
theme:. extends inherits a built-in, so a file only has to list what it
changes:
# ~/.config/terdut-tui/themes/mine.yaml
extends: gruvbox-dark
primary: "#d3869b"
accent: "#fabd2f"
A file may shadow a built-in name — themes/gruvbox-dark.yaml is how you tweak
the default without renaming it.
Without extends, every token must be set. The twelve are:
| Token | Where it shows |
|---|---|
primary |
header, active tab, selected row, cursors |
on_primary |
text drawn on primary — the active tab and selected row |
text |
incident titles and other emphasis |
muted |
secondary text, dividers, footer, table headers |
accent |
status line, acknowledged incidents, the by-day chart |
firing |
firing alerts, triggered incidents, the by-hour chart |
resolved |
resolved alerts and incidents, the top-alerts chart |
error |
error banners |
sev_critical, sev_error, sev_warning, sev_info |
the severity label |
Values are hex (#83a598 or #abc) or an ANSI palette index (0–255) if you
would rather follow your terminal's own colours. Colours are downsampled
automatically on 256- and 16-colour terminals, and NO_COLOR is honoured.

Shift the week window |
One person holds a given day. Assigning over days somebody else already has asks first — naming them and how many days are being taken — and moves the whole selection at once when you accept, so reassigning a week is one confirmation rather than seven deletions. The header line names the team whose rota this is, and "On-call today" lists everyone on call across your teams.
Users section:
| Key | Action |
|---|---|
n |
Create a user |
t |
Edit the user's ntfy topic — submit empty to clear it |
d |
Delete a user |
k |
API keys for the selected user |
p |
Set the selected user's web UI password — asks for the current one when it is your own |
In Users, k and d act on the selected row, so move with ↑/↓ there rather
than k. The Flags column marks administrators and disabled accounts. n and d
are for administrators; t, k and p work on your own row, or on anyone's if you
are one.
