Sleipnir

A local-first macOS control plane for observing agent work across projects.

Sleipnir is an experimental, open-source macOS application currently published as a source preview. It combines a multi-project Kanban board and exception console with provider-neutral task routing. When runtime profiles are configured, executor and commander profiles can be selected independently within one local installation.

Agent work, across projects

The board brings project scope, task state, live activity where supported, blockers, and human-review handoffs into one view.

One view can combine project scope, queued and active work, blockers, explicit human handoffs, and completed tasks. Available live controls depend on the configured runtime.

What exists today

  • Multi-project Kanban board and exception console
  • Provider-neutral runtime routing, with workflow depth varying by driver
  • Live in-memory activity events, plus steering and cancellation where supported

Current boundaries

  • Build from source; not a stable release or hosted service
  • Designed for one trusted operator on one local installation
  • Runtime capabilities, task completion, and available evidence vary; durable history is optional

Open-source foundations

Sleipnir was developed with two open-source projects at its foundation.

Garry Tan · knowledge + task ledger

GBrain

GBrain is the external knowledge and task ledger behind Sleipnir's live boards, including portfolios, projects, tasks, decisions, and context.

OpenAI · coordination model

Symphony

Symphony's open-source service specification shaped Sleipnir's coordination loop. Sleipnir independently implements polling, dispatch, isolated workspaces, retries, reconciliation, and human handoffs.
