Text Dropbox: Cross-device clipboard bridge

Send a snippet of text between Linux, VMs, phones, and VPN intranets in seconds

Problem

Developers live in fragmented environments: coding on Linux, running WeCom inside a VM, passing text between phone and laptop, or working through a VPN into a corporate network. Copy-paste between host and VM often breaks or crashes the VM, and sharing text across the VPN is even harder. Existing sync tools are either heavyweight or locked to big vendors.

Solution

A minimal real-time shared clipboard accessible from any browser plus a tiny CLI client. Log in, open the same clipboard on any device, and paste/view/copy instantly. Includes end-to-end encryption, history, per-device grouping, and auto-expiry.

Users

Multi-device developers, VM users, remote and intranet workers, anyone who frequently moves text between phone and computer

MVP

Browser-based real-time shared clipboard; minimal login and anonymous rooms; end-to-end encryption; history with one-click clear; curl write endpoint

Revenue

Free tier limits history and device count; subscription unlocks encrypted history, custom domains, and team clipboards; one-time self-host license as an alternative

Why now

Remote work and VM-based development are the norm, yet cross-platform and intranet clipboard sync remains painful; a lightweight WebSocket service is quick for a solo developer to ship
