engrams
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.
