Clinklog r1.6 (20K) is the current version as of 14 January 2019. It's open source under the MIT license, and only requires a Python runtime to work, version 3.2 or newer, including the standard library.
For now, Clinklog uses a command-line interface, so you'll also need a terminal emulator, Command Prompt or the like. Last but not least, the ability to publish files on a web server, e.g. via FTP.
