ttyd - Share your terminal over the web

ttyd is a simple command-line tool for sharing terminal over the web, inspired by GoTTY.

Features

• Build on libwebsockets with C for speed
• Full terminal emulation based on hterm
• SSL support based on OpenSSL
• Run any custom command with options
• Basic authentication support
• Cross platform: macOS, Linux, OpenWrt/LEDE

Installation

Install on macOS

Install with homebrew:

brew tap tsl0922/ttyd
brew install ttyd

Install on Linux

Ubuntu 16.04 as example:

sudo apt-get install cmake g++ pkg-config git vim-common libwebsockets-dev libjson-c-dev libssl-dev
git clone https://github.com/tsl0922/ttyd.git
cd ttyd && mkdir build && cd build
cmake ..
make && make install

NOTE: You may need to compile libwebsockets from source for ubuntu versions old than 16.04, since they have outdated libwebsockets-dev package (Issue #6).

Install on OpenWrt/LEDE

opkg install ttyd

NOTE: This may only works for LEDE snapshots currently, if the install command fails, compile it yourself.
