Codecademy lets you write and run code right in your browser [1], and Rosetta Code is a programming chrestomathy site [2]. Codecademy's Basic plan is always free [3], and it offers an AI Learning Assistant [1]. Rosetta Code has 1,360 tasks and is aware of 1,009 languages [2]. AnatomyOf shows annotated code examples [4], and it is free with no account and no paid tier [4].

The short answer

Codecademy lets you write and run code right in your browser [1]. Rosetta Code is a programming chrestomathy site [2].

On needs, Codecademy's page says it covers writing and running code in a browser [1], and it describes an AI Learning Assistant so you need not waste time searching online [1]. Rosetta Code's page describes a set of tasks and a count of languages it is aware of [2]. AnatomyOf's claims cover showing an example source file with color-coded callouts linked to the exact lines they explain [4], and running in any reasonably current desktop or mobile browser [4].

What Codecademy and Rosetta Code are built for

Codecademy's own page says signing up is free [1]. It lets you write and run code right in your browser [1]. The page also describes an AI Learning Assistant so there is no need to waste time searching online [1]. Its Basic plan is always free [3]. Paid plans are billed annually or monthly [3], annual plans include one complimentary workshop [3], and its page says that something comes with Codecademy Pro access [3].

Rosetta Code's own page calls it a programming chrestomathy site [2]. It currently has 1,360 tasks, 421 draft tasks, and is aware of 1,009 languages [2]. Content is available under the GNU Free Document License 1.3 unless otherwise noted [2].

What AnatomyOf is built for

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 [4]. Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link [4]. Each language has a minimal and a verbose example, and switching between them animates only the lines that change [4].

The same annotated format extends to non-code concepts such as an email and a CI pipeline [4]. Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations [4]. The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search [4], and code is highlighted with Shiki, the engine VS Code uses [4].

Pricing and fees

Codecademy's Basic plan is always free [3] and signing up is free [1]. One paid plan costs $14.99 a month billed annually or $29.99 billed monthly [3]. Another costs $19.99 a month billed annually or $39.99 billed monthly [3]. Annual plans include one complimentary workshop [3].

The Rosetta Code sources given here state no price, so a price is not published here; the site says content is available under the GNU Free Document License 1.3 unless otherwise noted [2].

AnatomyOf is free, with no account and no paid tier [4]. It is open source under the MIT License [4]. No other price is stated in its claims.

Setting it up and daily use

Codecademy lets you write and run code right in your browser [1]. Its page describes an AI Learning Assistant that removes the need to search online [1]. The Codecademy facts here say nothing more about setup, so check its site for how a course is started.

The Rosetta Code facts here give no install or setup steps, so check the site for how tasks are browsed or contributed.

AnatomyOf runs in any reasonably current desktop or mobile browser [4], there is nothing to install, and to run it locally you use bun install and bun run dev [4]. It has light and dark themes and works on phones, where you tap to pin a callout [4]. Entries have shareable URLs such as /#/python/verbose [4].

Things to check before you choose

Ask whether you want to write and run code in a browser or look at a set of tasks across languages. Codecademy's page describes writing and running code in your browser [1], and Rosetta Code's page describes tasks and languages it is aware of [2].

Ask what fits your budget and how you are billed. Codecademy prices its paid plans yearly or monthly [3], and the Rosetta facts give no price, so check the site.

Ask what you want from examples. AnatomyOf shows annotated examples tied to the exact lines they explain [4].

Ask what the tool sends about your use. AnatomyOf sends one anonymous visit ping per browser session on page load, and the README says it collects anonymous usage statistics [4]. Check Codecademy and Rosetta Code for their own policies, since the facts here do not cover them.

How to choose

If you want to write and run code right in your browser, Codecademy's page says you can [1]. If you want an AI Learning Assistant so you need not search online, Codecademy's page describes that [1].

If you want a programming chrestomathy site with 1,360 tasks and 1,009 languages it is aware of, Rosetta Code's page describes that [2].

If you want annotated code examples linked to the exact lines they explain, AnatomyOf's claims describe that [4]. If you want a free tool with no account, AnatomyOf's claims say it is free with no account and no paid tier [4].
