TigerJython is a simple development environment for programming in Jython. It contains all the necessary components for programming, is free and works under Windows, MacOS and Linux. The distributions use a platform-specific embedded Java Runtime Environment (JRE). It is therefore not necessary to install the JRE. No Java will be installed on the system and an existing Java installation will not be changed.
