Exercism is a practice site that builds fluency in 84 programming languages and is 100% free forever [^1][^1]. Rosetta Code is a programming chrestomathy site, a collection where the same task is solved in many languages [^2]. AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain [^3]. | Option | Free to use | Paid option | What it covers | Setup | |---|---|---|---|---| | Exercism | 100% free, forever [^1] | Insiders access via recurring monthly donation of $10 or more [^4]; lifetime for donating $499 total [^4] | 84 programming languages [^1]; over 8,744 coding exercises [^1]; free human mentoring [^1] | CLI-first, with an in-browser editor [^1] | | Rosetta Code | Price not published; content under GNU Free Document License 1.3 [^2] | Not published | 1,360 tasks, 421 draft tasks, aware of 1,009 languages [^2] | Not published | | AnatomyOf | Free, with no account and no paid tier [^3] | No paid tier is stated; it is free [^3] | Annotated source examples [^3]; language list sorted by TIOBE Index [^3] | Nothing to install; bun install and bun run dev [^3] | ## The short answer Exercism is a practice site that develops fluency in 84 programming languages and is 100% free forever [^1][^1]. Rosetta Code is a programming chrestomathy site, meaning a collection that presents the same task solved in many languages [^2]. AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain, with a minimal and a verbose example per language [^3][^3]. On needs, Exercism's page says it is fun, effective and 100% free forever [^1], and offers free human mentoring [^1]. Rosetta Code's page says it is a programming chrestomathy site, a collection where the same task is solved in many languages [^2]. AnatomyOf's claims cover annotated examples [^3] and a language list ranked by TIOBE Index [^3]. ## What Exercism, Rosetta Code is built for Exercism's own page says it is fun, effective and 100% free forever, and that it helps you develop fluency in 84 programming languages [^1][^1]. It says you can deepen your knowledge with human mentoring, for free [^1]. It is primarily built as a CLI-first tool, with an in-browser editor [^1]. Rosetta Code's own page calls it a programming chrestomathy site, a gathering of the same task solved in different languages [^2]. Content is available under 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 [^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], and 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]. Code is highlighted with Shiki, the engine VS Code uses [^3]. Entries have shareable URLs such as /#/python/verbose [^3]. It has light and dark themes and works on phones, where you tap to pin a callout [^3]. ## Pricing and fees Exercism is 100% free forever [^1]. The easiest way to get Insiders access is a regular monthly donation of $10 or more [^4], and lifetime access is granted once you have donated $499 in total [^4]. Exercism Premium was discontinued in August 2023 [^4]. Rosetta Code: the facts here state no price, so its price is not published here. Content is available under GNU Free Document License 1.3 unless otherwise noted [^2]. AnatomyOf is free, with no account and no paid tier [^3]. It is open source under the MIT License [^3]. No paid tier price is stated in its claims. ## Setting it up and daily use Exercism is primarily built as a CLI-first tool, and there is also an in-browser editor [^1]. Human mentoring is free [^1]. The facts here give no step-by-step setup, so check Exercism's own pages for how to install and start. Rosetta Code is a programming chrestomathy site [^2] that collects 1,360 tasks and is aware of 1,009 languages [^2]. The facts here give no setup or installation steps. AnatomyOf has nothing to install; to run it locally, use bun install and bun run dev [^3]. It runs in any reasonably current desktop or mobile browser [^3]. Daily, you move through the language list and search it instantly [^3], hover a callout to highlight its code, and click to open the longer writeup [^3]. It has light and dark themes and works on phones, where you tap to pin a callout [^3]. ## Things to check before you choose Ask what you want the tool to give you. Exercism's page speaks of fluency in 84 languages and free mentoring [^1][^1], and Rosetta Code's page speaks of a programming chrestomathy site where the same task is solved in many languages [^2]. Check how you like to read code. Exercism is primarily CLI-first [^1], and AnatomyOf is a browser page with annotated callouts [^3]. Check cost and accounts. Exercism is free, with Insiders tied to donations [^4], and AnatomyOf is free with no account [^3]. The facts give no price for Rosetta Code. Check what data leaves your machine. AnatomyOf sends one anonymous visit ping per browser session on page load [^3]. Check Exercism's and Rosetta Code's own pages for their data handling, since the facts here do not cover it. ## How to choose If you want to practise programming and build fluency in a language, Exercism's page says it offers 84 languages and free mentoring [^1][^1]. If you want to see how many different languages solve the same task, Rosetta Code's page collects tasks across languages [^2][^2]. If you want an annotated example source file with callouts linked to the exact lines they explain, AnatomyOf's claims describe that [^3]. If you want a free tool with no account, AnatomyOf's claims say it is free with no account and no paid tier [^3], and Exercism's page says it is 100% free forever [^1]. ## Frequently asked questions ### Is Exercism free to use?
