The short answer

DevDocs combines multiple API documentations in one searchable interface ^[1]. AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain ^[2]. No QuickRef facts are given for this page, so its purpose is not stated here; check QuickRef's own pages for what it covers.

On needs, DevDocs's page says it offers instant search, offline support, a mobile version, a dark theme and keyboard shortcuts ^[3]. It can be searched from the browser's address bar ^[1], and it works without a connection ^[1]. AnatomyOf's claims cover annotated code examples ^[2]. The same format extends to non-code concepts such as an email and a CI pipeline ^[2]. The language list is sorted by TIOBE Index rank and has instant search ^[2].

What DevDocs and QuickRef are built for

DevDocs's own page says it combines multiple API documentations in a fast, organized, and searchable interface ^[1]. It was created by Thibaut Courouble and is operated by freeCodeCamp ^[3]. The page lists a dark theme among its features ^[3]. DevDocs supports keyboard shortcuts, so you do not need a mouse ^[1]. You can also search using your browser's address bar ^[1]. It works without a connection, on mobile, and can be installed as a web app ^[1]. It is free and open source ^[1].

No QuickRef facts are given for this page, so nothing about what QuickRef is built for is stated here. Check QuickRef's own pages for what it covers.

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 ^[2]. Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link ^[2]. Each language has a minimal and a verbose example, and switching between them animates only the lines that change ^[2].

It extends the same annotated format to non-code concepts such as an email and a CI pipeline ^[2]. Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations ^[2]. The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search ^[2]. Code is highlighted with Shiki, the engine VS Code uses ^[2]. Entries have shareable URLs such as /#/python/verbose ^[2]. It has light and dark themes and works on phones, where you tap to pin a callout ^[2].
