Blink is a Session Initiation Protocol (SIP) client distributed under the Blink license (GNU GPLv3 with an exception to permit the inclusion of commercial proprietary modules).[4][5]

The software is written in Python for macOS's Cocoa, with a later port to Qt for supporting Microsoft Windows, Linux, AmigaOS.[6][7]

Features

Blink is based on the Session Initiation Protocol, and beyond voice over IP, its features also include video, instant messaging, file transfer, and multi-party conferencing sessions based on MSRP protocol, remote desktop sharing using RFB protocol (VNC), and SIMPLE presence using XCAP protocol. Compatible with Asterix.[8]

Alternative to Skype

According to Jason Hibbets, an Advisor at Red Hat, Blink is a popular alternative to Skype[9]

Privacy and Security

The Linux and macOS version of Blink implement OTR protocol end-to-end encryption and peer verification for chat media.[6][10] All versions provide audio and video media encryption using ZRTP.[11]
