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.[1][2] 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.[3]

Rosetta Code was created in 2007 by Michael Mol.[3] 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[update], 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.

The Rosetta Code site is organized as a browsable cross-section of tasks (specific programming problems or considerations) and computer programming languages.[2] 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.
