Open-source, self-hosted software factory that runs Claude Code, Codex or your own harness in Firecracker microVMs in your cloud.

## Overview

engrams is Cortex’s open-source, self-hosted software factory. It runs Claude Code, Codex or your own agent harness in Firecracker microVMs inside your cloud, and work can be started from Slack, a schedule, a pull request or a webhook.

An automations builder defines what runs and when. Cortex uses it internally for dependency upgrades, CVE fixes and bug triage.

The orchestrator is AGPL-3.0, with harness SDK crates under Apache-2.0. engrams is free, with no hosted service; Cortex separately sells an internal developer portal.

## Features

* Runs Claude Code, Codex or your own harness.
* Isolates each run in a Firecracker microVM in your cloud.
* Starts work from Slack, a schedule, a pull request or a webhook.
* Includes an automations builder.
