Workspaces, tabs and the daemon

Interactive malac runs in a background daemon, one per user. The terminal UI, the line mode, the web UI and the VS Code extension are all clients of it. That is what makes these things work:

• Agents keep running after you close the terminal. Quit the terminal UI (or close the window) and the agents carry on in the daemon; run malac again to come back to them.
• Work survives a reboot. Workspaces are saved to disk and restored when the daemon starts again. Agents come back idle and resume from their transcripts when you prompt them.
• Several clients at once. Two terminals, a browser and VS Code can work on the same workspace at the same time and see the same agents live.
• Approvals close everywhere. A permission request appears in every connected client; the first answer wins, and the dialog disappears in the others.

Workspaces and tabs

Thing	What it is
Workspace	A set of tabs: what you work on together, for example one feature across a backend and a frontend repository. You can keep several and switch between them.
Tab	A project: one folder, with that folder’s configuration, instructions and tools, and the agents working in it.
Agent	A conversation in a tab. A tab can hold several top-level agents side by side, each with its own subagents.

Each tab loads its project’s .malac/config.toml, AGENTS.md, skills and agent types, and connects its MCP servers, the first time an agent in it is used. The permission mode is set per tab.

Opening work from the command line

Command	What it opens
malac	The last workspace, from any folder, with all its tabs, where you left it
malac <prompt>	The last workspace, with a new tab for this folder running the prompt
malac --name api <prompt>	The same, with the new tab named api
malac -n	A fresh workspace; the previous one stays saved
malac -n --name release	A fresh workspace named release
malac -w release	The workspace release, by name or id
malac -c	The last session started in this folder, in its tab
malac -r <id>	A saved session, in the tab that holds it or a tab for its folder

The first time, malac creates a workspace called default. -n and -w cannot be combined. These options work the same in the full-screen UI and with --plain.

Managing workspaces

malac workspaces                          # list them; * marks the last used one
malac workspaces rename default backend   # rename, by name or id
malac workspaces delete old               # delete; its sessions stay on disk
malac workspaces delete old --force       # even while its agents work (stops them)

* default  01a17450  3 tabs · 1 running  2026-10-25 20:14
  release  01a17462  1 tabs  2026-10-24 17:02

The terminal UI’s Session menu and the web UI’s workspace switcher do the same: new, switch, rename and delete. Workspaces are saved in ~/.malac/workspaces/, and ~/.malac/state.json remembers the last one.

The daemon

Clients start the daemon when it is not running, so most of the time you never think about it. It listens on 127.0.0.1:7700 (web.port, or any free port), serves the web UI, and writes ~/.malac/daemon.json so clients can find it.

Command	What it does
malac daemon or malac daemon start	Start it in the background, unless it runs; output goes to ~/.malac/daemon.log
malac daemon run	Run it in the foreground, logging to the terminal
malac daemon status	Version, address, clients, workspaces, running agents and jobs, and when it exits
malac daemon status --json	The same as JSON
malac daemon stop	Stop it. Refused while agents or jobs run; --force stops them.
malac daemon restart	Stop and start, for example after an update. Same --force rule.

$ malac daemon status
malac daemon 1.0.0 (pid 68119) since 2026-10-25 18:33
  url        http://127.0.0.1:7700/?token=8995bbb2…
  clients    2
  workspaces 2 · 3 tabs loaded
  running    1 agents · 0 jobs · 0 waiting for approval
  exits      after 120 minutes without clients or work
  log        /Users/you/.malac/daemon.log

start, run and restart take --port, --host, --remote (listen on every interface; the token is still required) and --token.

When it exits

The daemon exits after daemon.idle_minutes (default 120) with no clients, no running agents or jobs and no pending approvals. Set it to 0 to keep it running:

~/.malac/config.toml

[daemon]
idle_minutes = 0
browse_root = "~/code"   # the web UI's pickers show only what is below this (default: home)

The daemon reads [daemon], [web], [update] and [control] from your user configuration only; each tab loads the full configuration of its own folder. The daemon keeps the environment it was started with, so after changing an API key variable, run malac daemon restart, or store the key with malac provider add --api-key-stdin.

After an update

Updating malac never touches a running daemon: it keeps the version it started with until it restarts. When the terminal is newer than the daemon, the terminal UI shows daemon 1.0.0 running; restart it when idle in the status line (click it, or Help → Restart the daemon), the line mode prints a notice when it connects, and malac daemon status suggests malac daemon restart.

What runs where

Command	Runs in
malac (full-screen UI)	The daemon, starting it if needed
malac --plain, or ui.tui = false	The daemon, starting it if needed; in its own process if the daemon cannot be reached
malac web, the web UI, the VS Code extension	The daemon
malac -p, malac --json, piped input, no terminal	Its own process: it never starts the daemon, and the run ends with the command

So scripts and CI are unaffected by the daemon: see Plain mode and scripting.

If the daemon cannot start, the full-screen UI says so and suggests malac --plain or malac -p. If the connection drops, the terminal UI shows it and Ctrl+R reconnects, starting the daemon again if needed.

Files

Path	What it is
~/.malac/daemon.json	Address, token, pid and version of the running daemon (mode 0600)
~/.malac/daemon.token	The web UI token, kept across restarts so open pages reconnect; delete it to get a new one
~/.malac/daemon.lock	Keeps two daemons from serving one home
~/.malac/daemon.log	The background daemon’s output
~/.malac/workspaces/<id>.json	Saved workspaces
~/.malac/state.json	The last workspace used
~/.malac/jobs/	Background jobs and their logs

Clients talk to the daemon over a documented WebSocket and HTTP API; see Protocol.
