Rosetta Code is a wiki-based programming chrestomathy website with implementations of common algorithms and solutions to various programming problems in many different programming languages.[2][3] It is named for the Rosetta Stone, which has the same text inscribed on it in three languages, and thus allowed Egyptian hieroglyphs to be deciphered for the first time.[1]



Rosetta Code was created in 2007 by Michael Mol.[1] 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.[4]

The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various programming paradigms,[5][6] and how "the same" task is accomplished in different programming languages.[7]

As of 22 February 2024, Rosetta Code has:[8]

  • 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.[9]

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.[3] 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 Ruby, the task will appear in the listing for Ruby as well.



Some of the computer programming languages found on Rosetta Code (which have Wikipedia descriptions) include: [10]

A complete list of the computer programming languages that have examples (entries/solutions to the Rosetta Code tasks) is available.[11]



Some of the tasks found on Rosetta Code include:[12]
