iOS and web.
Your computers.
Use the native Supen app on iPhone and iPad, or open the web app on your phone, tablet or laptop. Your computers connect outward; neither client needs VPN or SSH setup.

Same agents.
Different ways in.
Supen, Collie and Moshi keep the coding agents on your own computer within reach. The difference is how you connect, where you work, and what you want around the terminal.

The connection is a choice
Convenience has
a different shape.
Supen’s native iOS app and Web / PWA use the same account and connected computers. Choose the native interface on iPhone or iPad, or use a browser on another device. Native app access and the connection method are separate choices.
Supen uses a gateway to reach computers that connect outward. That removes the need to set up SSH access or a VPN on each viewing device. It also introduces a relay hop and a dependency on the gateway being reachable.
Moshi’s direct connection suits people who already manage SSH access. Collie lets you choose the ingress you host and control. Those are useful strengths, not boxes we need to tick away.
In all three approaches, the native terminal tools hold the work. Closing a viewing client is separate from stopping the agent.
Beyond remote access
Reach the work.
Then reduce the chasing.
Remote terminal access is the direct path to your coding agents. Supen’s personal assistant is a separate experience in both the iOS app and web app for routine coordination, follow-through and the decisions that need you. It keeps the work itself within reach.
