What is Hexcore?
Hexcore is a cloud relay service that connects multiple Hexdeck instances across different machines. It enables real-time team coordination for AI coding operators — without any of your source code leaving your machine.
How it relates to Hexdeck
Hexdeck is the local, open-source control plane that runs on your machine. It monitors AI operator activity, detects conflicts, and provides a dashboard — all offline.
Hexcore extends Hexdeck to work across machines. When you connect your Hexdeck instance to a Hexcore, your team gets:
- Real-time presence — see which operators are active across all machines
- Cross-machine conflict detection — prevent collisions between teammates' operators
- Team dashboard — a shared view of all operator activity on the cloud dashboard
- Invite system — add teammates with a single link
Architecture
Machine A (Hexdeck) ──WebSocket──▶ Hexcore Relay ◀──WebSocket── Machine B (Hexdeck)Each Hexdeck instance maintains a WebSocket connection to the Hexcore relay. Operator presence, intent, and collision data flows through the relay in real time. No source code is ever transmitted — only metadata like file paths, task summaries, and session statistics.
Getting started with Hexcore
- Make sure Hexdeck is installed and running
- Follow the Cloud Relay setup guide
Hexcore is currently free during the beta period.
