Compare syntax references by how they teach, search and license their content: Learn X in Y Minutes, Exercism, DevDocs, Rosetta Code and more.

The options differ in what they put first: short tours, exercises, searchable documentation, side-by-side tasks, or annotated examples. Pick by the question you are asking: how a language looks, how to practice it, or where a detail is documented.

| Option | Main role | Published cost or licence detail |
|---|---|---|

## How to read this list

These sites overlap around one need: seeing how a language is written. The difference is the shape of the help. Learn X in Y Minutes describes itself as community-driven. [^1] Exercism is built primarily as a CLI-first tool. [^2] Codecademy has a browser code editor. [^3] DevDocs combines multiple API documentations in a searchable interface. [^5] W3Schools says learning is free with or without an account. [^6] Rosetta Code is a programming chrestomathy site. [^8] AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain. [^9]

A useful way to narrow the list is to decide whether you want to read, practice or look something up.

## Learn X in Y Minutes: community-written language tours

Learn X in Y Minutes invites readers to take a whirlwind tour of a language, and describes itself as community-driven. [^1] New languages are added through GitHub pull requests. [^1] Articles are licensed under CC BY-SA 3.0. [^1]

## AnatomyOf: annotated example files for each language

AnatomyOf is made by the team that publishes this site. It shows an example source file with color-coded callouts linked to the exact lines they explain. [^9] Hovering a callout highlights its code, and clicking it opens a longer writeup. [^9]

Each language has a minimal and a verbose example, and switching between them animates only the lines that change. [^9] The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search. [^9] Entries have shareable URLs. [^9]

AnatomyOf is free, with no account and no paid tier. [^9] It is open source under the MIT License. [^9] It runs in any reasonably current desktop or mobile browser. [^9] It sends one anonymous visit ping per browser session on page load. [^9]

## How to choose

To see how one language is laid out, Learn X in Y Minutes offers a short tour. [^1] To understand which line does what, AnatomyOf links callouts to exact lines. [^9] To compare minimal and fuller code for a language, it has both examples. [^9]

To practice, Exercism offers exercises and free mentoring. [^2] [^2] To write and run code in the browser, Codecademy has an editor. [^3] To look up documentation quickly, DevDocs has fuzzy search and keyboard shortcuts. [^5] [^5] To see one task solved in many languages, Rosetta Code is built for that. [^8]

Before choosing, check which languages each site covers, how current the content is, and whether you want to read or to practice.
