DevDocs vs Rosetta Code in 2026

Q: Is AnatomyOf free and open source?

AnatomyOf is free, with no account and no paid tier , and is open source under the MIT License . It runs in any reasonably current desktop or mobile browser , and needs nothing installed to browse it . The sources here state no paid tier, so the only price they give is free .

DevDocs and Rosetta Code compared on what each does, what each costs, and how their references fit different coding needs.

Rosetta Code is a site that presents solutions to the same task in many programming languages ^[1]. DevDocs is free and open source ^[2]. AnatomyOf shows example source code with color-coded callouts linked to the exact lines they explain ^[3].

Rosetta Code's page says its content sits under the GNU Free Document License 1.3 ^[1]. DevDocs' page says it is free and open source ^[2]. AnatomyOf's claims cover annotated code callouts ^[3] and a short version and a longer version of each example ^[3]. The facts here do not state a price for Rosetta Code, so its price is not published here.

Option	Content	Price	License	Data
DevDocs	Combines multiple API documentations in one fast, organized, searchable interface ^[2]	Free and open source ^[2]	Open source ^[2]	Publisher would like to gather usage data through Google Analytics and Gauges ^[2]
Rosetta Code	1,360 tasks, 421 draft tasks, 1,009 known languages ^[1]	Price not published	Content under GNU Free Document License 1.3 ^[1]	Not stated
AnatomyOf	Annotated callouts linked to example code lines ^[3]	Free, no account, no paid tier ^[3]	MIT License ^[3]	One anonymous visit ping per session on page load ^[3]

The short answer

Rosetta Code is a site that presents solutions to the same task in many programming languages ^[1]. DevDocs is free and open source ^[2]. AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain ^[3].

Rosetta Code's page says its content is available under the GNU Free Document License 1.3 ^[1]. DevDocs' page says it is free and open source ^[2]. AnatomyOf's claims cover annotated code callouts ^[3] and a short version and a longer version of each example ^[3]. The facts here give few other details about what the two rivals do, so those details are not stated on this page.

What DevDocs and Rosetta Code are built for

DevDocs' own page says it is free and open source and asks for a GitHub star ^[2]. DevDocs' page says its publisher would like to gather usage data through Google Analytics and Gauges ^[2].

Rosetta Code's own page calls itself a site that presents solutions to the same task in many programming languages ^[1]. Its content is available under the GNU Free Document License 1.3 unless otherwise noted ^[1].

What AnatomyOf is built for

AnatomyOf is made by the team that publishes this site.

AnatomyOf 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 short version and a longer version of its 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 add 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]. Code is shown with the same colors a developer sees in a code editor ^[3]. A reader can link straight to an entry ^[3]. It has light and dark themes and works on phones, where you tap to pin a callout ^[3]. New languages can be added with a single file ^[3].

Pricing and fees

Rosetta Code's page does not state a price, so any cost to use it is not published here. AnatomyOf is free, with no account and no paid tier ^[3], and is open source under the MIT License ^[3]. The sources here state no paid tier for AnatomyOf, so the only price they give is free ^[3].

Setting it up and daily use

Check each tool's own pages for details on setup and daily use that are not covered by the facts here.

AnatomyOf needs nothing installed to browse it, and it runs in any reasonably current desktop or mobile browser ^[3] ^[3]. Daily use is browsing entries, where hovering a callout highlights its code and clicking opens a longer writeup ^[3], and a reader can link straight to an entry ^[3].

Things to check before you choose

Ask what you are looking up. Rosetta Code's page calls itself a site that presents solutions to the same task in many programming languages ^[1], and AnatomyOf's claims are about annotated examples ^[3].

Check whether the languages you use are covered, since none of the sources here list every language. Check data handling: AnatomyOf sends one anonymous visit ping per session on page load ^[3]. Check how each tool is used and kept up to date on its own pages, since the facts here cover little of their setup and daily use.

How to choose

If you want the DevDocs option described in the table, check its own pages for the details you need.

If you want a site that presents solutions to the same task in many programming languages, Rosetta Code's page describes that ^[1].

If you want example code explained line by line with callouts, AnatomyOf's claims describe that ^[3], alongside a short version and a longer version of each example ^[3] and the same annotated format for non-code topics such as an email and a CI pipeline ^[3].

If you want a free tool, DevDocs' page says it is free and open source ^[2], and AnatomyOf's claims say it is free, with no account and no paid tier ^[3].

Frequently asked questions

Is DevDocs free to use?

DevDocs is free and open source, and its page asks for a GitHub star rather than a fee ^[2]. No paid plan is stated in the sources here, so check the project's own pages if you need detail on future plans.

Does Rosetta Code cost anything?

Rosetta Code's page does not state a price, so any cost is not published here. Its content is available under the GNU Free Document License 1.3 unless otherwise noted ^[1]. The sources here give no fee or account details, so check Rosetta Code's own pages on cost and licensing before relying on it.

Is AnatomyOf free and open source?

AnatomyOf is free, with no account and no paid tier ^[3], and is open source under the MIT License ^[3]. It runs in any reasonably current desktop or mobile browser ^[3], and needs nothing installed to browse it ^[3]. The sources here state no paid tier, so the only price they give is free ^[3].

How are DevDocs and AnatomyOf set up?

AnatomyOf needs nothing installed to browse it, and it runs in any reasonably current browser ^[3] ^[3]. The facts here say little about how DevDocs and Rosetta Code are installed and used day to day, so check each one's own pages on setup and routine use.

Does AnatomyOf collect data about the machine?

AnatomyOf sends one anonymous visit ping per browser session on page load, and its README says it collects anonymous usage statistics ^[3]. DevDocs' page says its publisher would like to gather usage data through Google Analytics and Gauges ^[2]. Rosetta Code's page does not state what it collects, so check its own pages before using either in a sensitive setting.
