Agent runtime Internal · running in production

Ghost

A runtime for coding agents that keeps working when you close the laptop.

Ghost is the platform our engineering work runs on. It turns a model, a repository and a set of tools into a durable, server-owned session you can leave and come back to — from a terminal, a browser, or a phone on a bad connection.

The problem we kept hitting

Agent tooling assumes a developer sitting still in front of one terminal. Close the lid, lose the tunnel, switch devices — the work dies with the connection. Swap the model and the transcript has to be rewritten. Every vendor invents its own shape for the same conversation.

Ghost inverts that. The run belongs to the server, the transcript belongs to us, and the model is a detail you change per message.

What it does

Vendor-neutral core

One internal contract describes a conversation, its tools and its reasoning. Model providers plug in behind it, so switching vendors is a configuration change, not a migration.

Runs that survive the client

Work is owned by the server, not the browser tab. Connections drop, phones sleep, laptops close — the run keeps going and you reattach to it later.

Resumable sessions

Every session has a durable transcript. Reattaching replays where you left off and then follows live, on any device.

Tools that reach real systems

Agents operate on real repositories and real processes through a controlled tool layer, including standards-based integrations with external tool servers.

Thin, swappable clients

Clients speak only the published stream contract. The terminal client and the web client share no code with the core, so a new surface is days of work, not a rewrite.

Self-hosted and private

Ghost runs on our own infrastructure, inside our own network. No third party sits between us, our source code, and the model.

How we build it

  • The stream contract is the product; everything else is replaceable.
  • Persistence before features — a lost transcript is a lost day.
  • Isolation is a boundary we design for, not a setting we hope for.

Ghost is internal infrastructure. It is not sold, licensed, or offered for sign-up today.
