How does Kaizen Relay work?

Kaizen Relay creates a secure tunnel between your local dev machine and the Kaizen cloud, letting you access your coding agent workspace from any device with a browser.

Can I use Kaizen from my phone?

Yes. With Kaizen Relay, you can access your local AI coding agent workspace from your phone or tablet browser. Use kaizen --remote to start a relay session and scan the QR code.

Is the relay connection secure?

Yes. All relay traffic is encrypted end-to-end. The connection authenticates through your Kaizen account and each machine has its own credential that can be rotated.

Remote Access

Your dev machine, from anywhere

Kaizen Relay connects your local AI coding workspace to your phone, tablet, or any browser — securely and in real time.

How Relay Works

Three steps to remote access

No VPN configuration, no port forwarding. Just a secure relay tunnel.

Start locally

Run `kaizen --remote` on your development machine. Kaizen starts the workspace and registers a relay tunnel.

Secure relay

Kaizen Relay creates an encrypted tunnel between your machine and the cloud. No ports are exposed publicly.

Connect from any device

Open the relay URL on your phone, tablet, or laptop. Your full workspace is available in the browser.

QR Handoff

Scan and go

Kaizen prints a QR code when you start with --remote. Scan it with your phone to open the workspace instantly — no typing URLs.

Note: QR handoff also works with Tailscale for direct local-network connections without the relay.

Security

Built for trust

Remote access to your dev machine demands strong security guarantees.

Encrypted Tunnel

All relay traffic is encrypted end-to-end. Your code never sits unencrypted on third-party infrastructure.

Account Authentication

Relay access requires a Kaizen Plus subscription and is tied to your account. Each machine has its own credential that can be rotated or revoked.

Code from anywhere

Set up remote access to your AI coding workspace in minutes.
