Rosetta Code was created in 2007 by Michael Mol. The site's content is licensed under the GNU Free Documentation License 1.2, though some components may be dual-licensed under more permissive terms. The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various

programming paradigms A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. A programming language can be classified as supporting one or more paradigms. Paradigms are separated along and descri ...

, and how "the same" task is accomplished in different programming languages. , Rosetta Code has: * 1,266 computer programming tasks (or problems) * 404 additional draft programming tasks * 933 computer programming languages that are used to solve tasks In August 2022, Rosetta Code migrated from independent hosting to Miraheze. Presently, Rosetta Code is hosted by WikiTide.

Data and structure

The Rosetta Code site is organized as a browsable cross-section of tasks (specific programming problems or considerations) and computer programming languages. A task's page displays visitor-contributed solutions in various computer languages, allowing a viewer to compare each language's approach to the task's stated problem. Task pages are included in per-language listings based on the languages of provided solutions; a task with a solution in the C programming language will appear in the listing for C. If the same task has a solution in
