Rainmeter is a free and open-source desktop customization utility for Windows released under the GNU GPL v2 license. It allows users to create and display user-generated customizable desktop widgets or applets called "skins" that display information.[2][3] Ready to use collections of skins can be downloaded and installed in packages known as "suites".[4]

Common functionalities of Rainmeter skins include desktop clocks, RSS readers, system monitors, weather widgets, application launchers and audio players.[5][6]


The Rainmeter project was originally founded by Kimmo 'Rainy' Pekkola, the developer of Rainlendar, in 2001.[7] The project is primarily written in C++, while plugins can be written in either C++ or C sharp.[8]


Rainmeter skins are written in Rainmeter code using a text editor and stored as INI configuration files.[9] System resource values and other information such as weather or time are stored through "measure" values within a skin, which can then be shown through different kinds of customizable visual elements called "meters".[3]


CNET, in a 4 out of 5 star rating, praised the software's flexibility, wide variety of themes and "enthusiastic community", while noting the program "isn't as intuitive as it could be."[10] Softpedia also gave the software a 4 out of 5 star rating, citing its comprehensive tutorials and low system resource usage, while criticizing its lack of cross-platform support.[11]
