​
Overview

Starts the Spacebot daemon. This is the default command when you run spacebot without any subcommand.

​
Usage

spacebot start [OPTIONS]

​
Options

​
--foreground
boolean
default:"false"
Run in the foreground instead of daemonizing. When enabled, the process stays attached to your terminal and logs to stdout/stderr.
​
--config
path
Path to a custom config file. If not specified, Spacebot loads configuration from the default location (~/.spacebot/config.toml).
​
--debug
boolean
default:"false"
Enable debug-level logging. Increases log verbosity for troubleshooting.

​
Behavior

When you run spacebot start, the following happens:
  1. Checks if already running: If a daemon is already running, the command exits with an error showing the existing process ID.
  2. Runs onboarding: If this is your first time running Spacebot, you’ll go through an interactive setup wizard to configure authentication and basic settings.
  3. Validates configuration: Loads and validates your config file before starting the daemon to catch errors early.
  4. Forks to background: Unless --foreground is set, the process daemonizes and detaches from your terminal.
  5. Initializes subsystems: Starts the HTTP API server, messaging adapters (Discord, Telegram, etc.), and agent processes.
  6. Writes PID file: Stores the daemon’s process ID in ~/.spacebot/spacebot.pid for management commands.

​
Examples

​
Start daemon in background

spacebot start
Output: 
spacebot daemon started (pid 42819)

​
Start in foreground with debug logging

spacebot start --foreground --debug
Output: 
spacebot running in foreground (pid 42820)
[DEBUG] loading config from /home/user/.spacebot/config.toml
[INFO] starting HTTP API on 127.0.0.1:19898
[INFO] connected to Discord gateway
...

​
Start with custom config

spacebot start --config /etc/spacebot/production.toml

​
Default behavior

spacebot  # equivalent to 'spacebot start'

​
Error Cases

​
Already running

$ spacebot start
spacebot is already running (pid 42819)
Solution: Stop the existing daemon first with spacebot stop, or use spacebot restart.

​
Missing authentication

No LLM provider keys configured.
Please add a provider key via the web UI at http://127.0.0.1:19898
Solution: Run spacebot auth login or configure API keys via the web UI.

​
Invalid config

$ spacebot start --config invalid.toml
Error: failed to load config from invalid.toml
Caused by:
    TOML parse error at line 5, column 10
Solution: Fix the configuration syntax error before starting.

​
Foreground vs Background

ModeUse CaseLogsCtrl+C
Background (default)Production, always-onWritten to ~/.spacebot/logs/Does not stop daemon
Foreground (--foreground)Development, debuggingStdout/stderrStops daemon

​
Process Lifecycle

The daemon runs until:
  • You explicitly stop it with spacebot stop
  • The system shuts down or restarts
  • An unrecoverable error occurs (daemon exits with error logs)
The daemon does NOT automatically restart on failure. Use a process supervisor like systemd or Docker for production deployments.
