Pocket terminal, comment-section chaos
Show HN: Loopsy, a way for terminals and AI agents on different machines to talk
Your phone can boss around your laptop, and the comments are already fighting about it
TLDR: Loopsy lets you control your computer from your phone and even link multiple machines together, aiming to make remote command-line work feel easy. Commenters were torn between “this is brilliantly simple” and “great, now several computer helpers can fight over my files at once.”
A new project called Loopsy is pitching a very simple fantasy: your phone becomes a remote control for your computer. You can tap or even dictate a command on your phone, and your laptop runs it at home like an obedient intern. No sketchy router setup, no complicated networking maze, and the creator says you can host the middleman yourself using Cloudflare’s free tools. On paper, it sounds like catnip for people who want to manage coding tools and command windows from the couch, the train, or bed.
But the real show is in the replies, where the community instantly split into camps. One crowd was swooning. A fan said it feels less like remote control and more like all your machines becoming “one coherent organism,” which is either a glowing review or the plot of a sci-fi disaster movie. Another commenter loved the classic builder spirit: maybe it’s “reinventing the wheel,” but who cares if it just works? That got applause from the teach-by-doing crowd.
Then came the skeptics, dragging in the practical chaos. One person basically said, “Cool toy, but what happens when two robot helpers start editing the same file and everything explodes?” Another zeroed in on the biggest trust issue: why is Cloudflare in the middle at all, and can this please run on a normal personal server instead? And yes, somebody immediately replied with the timeless internet flex: their coworker already does this with a pile of other tools. In other words, Loopsy launched straight into the oldest tech drama of all: genius shortcut or just another way to create new problems faster from your phone?
Key Points
- •Loopsy lets users control a laptop terminal and AI coding agents from a phone using a self-hosted relay on Cloudflare Workers.
- •The connection model uses outbound WebSocket connections from both laptop and phone to a user-owned Cloudflare Worker, avoiding port forwarding, public IP setup, or VPNs.
- •The article highlights security details including HMAC-signed pair tokens, SHA-256-hashed secrets at rest, and bearer tokens sent in Sec-WebSocket-Protocol headers.
- •Loopsy includes real terminal support with PTY and ANSI rendering, persistent sessions, voice input, and optional per-session auto-approve settings.
- •The original Loopsy functionality supports agent-to-agent communication on a LAN via mDNS and MCP, including command execution, file transfer, shared state, and messaging.
