Breaking News
Loopsy, a novel open-source utility, has been unveiled on Hacker News, allowing terminals and AI agents to communicate directly across multiple machines. The tool, built by an independent developer, promises to eliminate idle computing resources by enabling file transfers, remote command execution, and even continuous AI sessions from different devices.
Key Features and Immediate Impact
The developer explains, "I wanted my two MacBooks to talk to each other—having one idle while I worked on the other felt like waste. Loopsy started as a simple file-transfer tool but quickly evolved." Today, users can run commands, execute coding agents remotely, and maintain Claude sessions from a phone while at the gym.
The system leverages a Cloudflare Worker to bridge remote connections, requiring only that the host laptop remains powered and connected. This effectively turns any device into a remote terminal gateway, a capability that could significantly impact how developers and AI researchers interact with their environments.
Background
From Personal Frustration to Practical Tool
The project originated from a simple observation: the developer often had two MacBooks, one idle. Rather than manually juggling files or SSH sessions, they built Loopsy to automate the interconnection. "Initially I just wanted to transfer files over the local network, then I added command execution. Eventually I was running coding agents from one machine to another—and it just worked."
The need to continue Claude sessions on a phone while away from the desk led to the Cloudflare Worker integration. The developer admits, "I know I might be reinventing the wheel, but I love that it just works." Notably, end-to-end encryption is still in development, with an iOS client pending review.
What This Means
Implications for Remote Computing and AI Workflows
Loopsy addresses a long-standing pain point for multi-device users: making idle machines useful without complex setup. For AI practitioners, the ability to start a coding session on a powerful desktop and continue it from a phone or tablet via a terminal agent is a significant productivity boost.
However, security remains a concern. Without full end-to-end encryption, sensitive commands sent through the Cloudflare Worker could be exposed. The developer acknowledges this, stating encryption is a priority. If implemented robustly, Loopsy could become a staple for distributed agent-based workflows, potentially reducing the need for dedicated VPNs or jump boxes.
Industry Context
Tools like Loopsy enter a growing ecosystem where AI agents increasingly require persistent, cross-device communication. While SSH and tools like Tailscale offer similar functionality, Loopsy's focus on AI agents and simplicity differentiates it. The project is still early—only 3 points on Hacker News with no comments—but its utility could spark broader adoption.
The Road Ahead
The developer plans to complete end-to-end encryption and release the iOS app pending approval. For now, Loopsy is functional for local network setups and remote sessions via the Cloudflare Worker. Users are invited to test and provide feedback, with the promise that "it just works."
Developers interested in leveraging idle computing resources or building cross-machine AI pipelines should watch this project closely. As the developer concludes, "Let me know your thoughts."
