vanth

Background jobs for coding agents.
Start the work. Get woken with the result.

Windows, macOS, Linux · Apache-2.0

Actual agent sessions. Long waits are sped up.Use fullscreen for a closer look.

Agent-driven.
From start to finish.

Jobs keep running independently.
The result returns to the agent that asked.

  1. Hand off the job

    The agent uses MCP, or the CLI with --wake-me, to start a detached command.

  2. Keep the context

    Output, progress and checkpoints stay with the job. The agent can go idle.

  3. Wake with the result

    vanth resumes the OpenCode or Codex session with the outcome attached.

Watch the work.

The actual vanth-monitor: live jobs, progress, metric plots and rerun analytics.

160 seekfs queries, charted live.Included with vanth.
