C3Control / Continuity

A control layer for coding agents

Keep the work moving, wherever you are.

C3 is a focused suite for developers working with AI coding agents: steer them from your phone or desktop, and carry their sessions and file state across machines — all through one private hub you host yourself.

Three apps / one working loop

Control the agent now. Continue the session later.

C3 / 01

Your agents, in reach.

C3 Mobile turns your phone into a precise, end-to-end encrypted control surface for the coding agents running on your machines.

  • Attention queue for blocked agents
  • Answer permission prompts anywhere
  • Live terminals, workspaces, and panes

C3 / 02

Set up once. Operate from the desktop.

C3 Desktop detects your local stack, guides hub and bridge setup, and becomes a full Herdr control room when the wiring is live.

  • Local or remote hub setup
  • Enroll machines, phones, and services
  • Signal, session cockpit, and terminals

C3 / 03

Your sessions, on every machine.

C3Sync carries native agent sessions and the working-tree state attached to every turn between the machines you own.

  • Resume natively across agents
  • Catch up after being offline
  • Rewind files to an earlier agent turn

C3 / Foundation

One hub. Both products. No cloud.

Everything routes through a single relay you host — a Raspberry Pi is enough. The c3sync CLI provisions it once; C3Sync and C3 Mobile ride it in isolated accounts that cannot read each other's data.

  • 01Provisioned by one CLI, in one sitting
  • 02Sync data and control traffic stay isolated
  • 03C3Sync runs standalone; Mobile adds bridges and Herdr

Local-first by design

Built around your machines, not ours.

The suite keeps the developer in control: payloads are sealed on your devices before they reach your hub, which routes ciphertext for both products.

  • No hosted code workspace
  • End-to-end encrypted sync and control payloads
  • Independent of any one agent vendor

C3 / Release updates

Follow the control room.

The public launch betas are available now. Join once for release notes, new platform qualification, and setup guidance across Mobile, Desktop, and Sync.

Beta access and release updates only. No marketing noise.
