The short answer

On needs, Codecademy's page mentions an AI Learning Assistant [1] and a free sign up [1]. DevDocs' page covers fuzzy search [2], keyboard shortcuts [2] and offline use on mobile [2].
What Codecademy and DevDocs are built for
Codecademy's page says you can write and run code right in your browser [1]. It offers an AI Learning Assistant [1]. Its page says one offering comes with Codecademy Pro access [4].
DevDocs combines multiple developer documentations in a clean, organized web UI with instant search, offline support, mobile version, dark theme, keyboard shortcuts, and more [5]. Search supports fuzzy matching [2]. To search one documentation, you type its name, then Tab [2]. You can also search from the browser's address bar [2]. Preferences let you enable more docs and customize the UI [2].
DevDocs was created by Thibaut Courouble and is operated by freeCodeCamp [5]. Its page says it is currently searching for maintainers [5].
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 [3]. Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link [3]. Each language has a minimal and a verbose example, and switching between them animates only the lines that change [3].
The same annotated format extends to non-code concepts such as an email and a CI pipeline [3]. Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations [3]. The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search [3]. Entries have shareable URLs [3]. It has light and dark themes and works on phones, where you tap to pin a callout [3].
Pricing and fees
Codecademy says signing up is free [1]. Its Basic plan is always free at $0 [4]. Plus costs $14.99 a month billed annually or $29.99 billed monthly [4]. Pro costs $19.99 a month billed annually or $39.99 billed monthly [4]. Annual plans include 1 complimentary workshop [4].

AnatomyOf is free, with no account and no paid tier [3]. It is open source under the MIT License [3].
Setting it up and daily use
Codecademy's page says you can write and run code right in your browser [1]. The facts here say nothing more about its setup or routine use.
DevDocs can be used on mobile and installed as a web app, and its page mentions offline use [2]. Day to day, you search with fuzzy matching [2] and use keyboard shortcuts instead of the mouse [2].
AnatomyOf has nothing to install, and it runs in any reasonably current desktop or mobile browser [3] [3]. To run it locally, use bun install and bun run dev [3]. You add a language by writing one LanguageDef TypeScript file under app/src/data/ [3]. Code is highlighted with Shiki, the engine VS Code uses [3].
Things to check before you choose
Ask whether you want to learn by doing exercises, look up reference pages, or read annotated examples. Codecademy's page speaks of writing and running code in the browser [1], and DevDocs' page speaks of combined API documentations [2].
Check cost. Codecademy has paid plans, so look at which plan includes what you need [4].
Check data handling. DevDocs says it gathers usage data through Google Analytics and Gauges [2]. AnatomyOf sends one anonymous visit ping per browser session on page load [3]. Check Codecademy's own pages, since the facts here do not cover it.
Check upkeep. DevDocs says it is searching for maintainers [5].
