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]

Perspective
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.
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.[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.
