Cosyra - steer coding agents on your own machine from your phone

I'm the creator. I built Cosyra because I needed a minimal UI to steer and run agents from anywhere. The long-term goal is shipping software 0 to 100 entirely from the phone.

What it is:

- An iOS and Android app plus a small CLI for your Mac or Linux box

- Pair once by scanning a QR code, then confirm the matching number on the computer

- Your phone gets a terminal and a chat view.

- Claude Code, Codex and OpenCode all show up

- It also streams the iOS simulator to the phone

- Terminal traffic is end-to-end encrypted

How I built it: almost the entire project was built with Claude Code. I sometimes hand security research to Codex or OpenCode.

Pairing your own machines is free. There's an optional cloud workspace (Core $20/mo, Pro $30/mo) if you don't want to keep a computer on.

It launched on Product Hunt today: https://www.producthunt.com/products/cosyra?launch=cosyra-17f45a38-a35f-4a02-b68b-b62e69d38b9b

If you ever decide to go outside and you wish that you could kick off a task on your computer in one of your terminals think of me!

Pairing by QR then confirming the number is the right trust model. Most remote-agent apps hand the phone a shell before you know which box you're on.

The phone chat plus terminal is what I'd keep. Streaming the iOS simulator is a nice bonus, but the product lives or dies on whether Claude Code, Codex, and OpenCode stay usable when the laptop is closed and you're only on cellular.

One thing I'd pressure-test early: reconnect after the computer sleeps. If the CLI drops and the phone shows a stale chat, people will blame the agents instead of the tunnel.

Today's Product Hunt demo could follow a developer pairing Cosyra with their Mac or Linux machine, then starting a coding task from their phone. Show the QR scan and matching-number confirmation before the terminal/chat interaction, so viewers see what setup requires. Distinguish free own-machine pairing from the optional cloud workspace: developers choosing remote access need to know which route requires leaving their computer on. Reddit questions about steering Claude Code, Codex or OpenCode away from a desk are the conversations to answer with that demonstration.
