An agent hub for your durable harnesses

Ember is a desktop agent hub. It ships with a durable harness and connects to your other instances too, bringing their sessions into one window grouped by project, so you can follow several agents without constantly switching clients.

Command line

The same release ships tinder, a single binary that also answers to ember and kiln. It sets up the Kiln harness, prints your endpoint and token, probes a running instance, and writes the background service.

chmod +x tinder-cli-linux-x64
./tinder-cli-linux-x64 setup --headless   # Kiln token + background service
./tinder-cli-linux-x64 status             # is Kiln answering?

An agent hub, not a harness

Ember works with durable harnesses and with OpenChamber. It ships with Kiln, a durable harness you can run locally or headlessly on a server, and it connects to OpenChamber instances you already have. In both cases the instance owns execution, queues, permissions, and session history. Ember makes that work easier to see and interact with, across every host you connect.

What it does

  • One workspace, multiple instances. Browse recent sessions across local, remote, and reachable SSH-backed instances, including remote durable harnesses over Tailscale.
  • Project-focused columns and tabs. Up to eight sessions can be open, with columns adapting to the available width and overflow becoming tabs.
  • Visible agent state. Buddy and Glyph avatars distinguish working, thinking, waiting for input, failed, and unread sessions.
  • Reliable composing. Per-session drafts, attachments, reply context, server-owned follow-up queues, and project notes.
  • Long conversations without the clutter. Virtualized transcripts, inline search, pinned messages, expandable tool output, and configurable reasoning display.
  • Personal model experience. The model picker shows observed usage statistics and your Helpful / Not helpful ratings — not an automatic leaderboard or model router.
  • Optional browser access over Tailscale. Use the same app remotely while Ember runs on your desktop.
