WORKS EVERYWHERE YOU CODE

SSH sessions

Run cinch on any remote server. Push a file, a command output, or raw text — it surfaces instantly on your local machine. No port forwarding, no scp gymnastics.

prod-server — ssh

user@prod:~$ cat deploy.log | cinch push
✓ pushed  148 bytes → relay

user@prod:~$ cinch push < /etc/nginx/nginx.conf
✓ pushed  4.8 KB — nginx.conf

Vim & Neovim

Yank in Vim and the text is already on your clipboard, everywhere. The cinch.vim plugin hooks into TextYankPost — no extra keystrokes required.

nvim — init.lua

# lazy.nvim
{ "cinchcli/cinch.vim" }

# yank any motion → auto-pushed
yy   " current line
yi"  " inside quotes
✓ pushed  42 bytes · clip #7

tmux & screen

Works inside any multiplexer. OSC 52 breaks in tmux — cinch doesn't. Plain HTTP from any pane, any nesting level.

local — tmux 0:1

~/project $ cinch push < config.json
✓ pushed  512 bytes · clip #14

Features

Everything the pipe needs

Cinch is infrastructure for moving data between machines — starting with developers, extending to AI agents.

Unix-native

Reads stdin, writes stdout. No SDK, no clipboard API. Drop it anywhere in an existing shell pipeline.

Real-time delivery

WebSocket relay delivers clips the moment they arrive. No polling, no round-trips.

Self-hostable relay

Single Go binary. Deploy on any VPS, Fly.io, or Docker. Your data stays on your server.

Cross-platform CLI

macOS, Linux, Windows. If it has a shell, it works. Binaries available for all three platforms.

Desktop agent

cinchd lives in your menu bar. Every push lands in your system clipboard before you reach Cmd+V.

Open source

AGPL 3.0 licensed. CLI, relay, and protocol are fully open. Self-host for free, forever.
