The short answer

Exercism's sources given here say little about how it works, so this page only covers what they say about its cost. Exercism is 100% free, forever [1]. GeeksforGeeks lists courses, such as a Java Backend course covering Spring Boot and Microservices [2]. AnatomyOf shows example code with color-coded callouts linked to the exact lines they explain [3].

For a course on a particular stack, GeeksforGeeks's listings name several options, including a MERN Full Stack course covering React, Node and MongoDB [2]. For annotated examples of a language's syntax, AnatomyOf's claims describe that [3]. Exercism's sources given here do not say whether it meets either need, so check its own pages before you decide.

What Exercism and GeeksforGeeks are built for

Exercism's page describes itself as fun, effective and 100% free, forever [1]. The sources given here say nothing further about its features, so this page adds nothing to that. Insiders access comes through donations, and lifetime Insiders is granted for donating $499 in total, in one chunk or many parts [4]. The easiest way to get Insiders access is a regular monthly donation of $10 or more [4].

One GeeksforGeeks course is a Java Backend course covering Spring Boot and Microservices [2]. Another is a MERN Full Stack course covering React, Node and MongoDB [2]. A DSA and System Design course is offered for learners from beginner to advanced levels [2]. The sources given here do not describe how these courses are taught.

What AnatomyOf is built for

AnatomyOf is made by the team that publishes this site. It shows example code 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 also have a Visual tab with diagrams generated from data, 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]. It highlights code with Shiki, the engine VS Code uses [3]. Each entry has its own shareable address [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]. Insiders access comes through donations, and the easiest route is a regular monthly donation of $10 or more [4]. Lifetime Insiders is granted for donating $499 in total [4].

The GeeksforGeeks sources given here do not publish the price of its courses, so this page gives none for them.

AnatomyOf is free, with no account and no paid level [3]. It is open source under the MIT License [3].

Setting it up and daily use

The Exercism sources given here do not describe installing or daily use, so this page says nothing about either. The GeeksforGeeks sources given here do not describe setup or daily use either.

There is nothing to install for AnatomyOf [3]. To run it on your own machine, use bun install and then bun run dev [3]. It runs in any reasonably current desktop or mobile browser [3]. On a phone, you tap to pin a callout [3].

Things to check before you choose

Ask whether a tool suits how you learn. Exercism's Insiders access comes through donations, so check whether that route suits you [4]. For GeeksforGeeks, check whether a course's topic matches your stack, since its Java Backend course covers Spring Boot and Microservices [2]. Check whether you need an account for either of the other two, since the GeeksforGeeks sources given here do not say. AnatomyOf needs no account [3]. It sends one anonymous visit ping per browser session on page load, and its README says it collects anonymous usage statistics [3]. Decide whether that suits you.

How to choose

If you want annotated examples of a language's syntax, AnatomyOf's claims describe that [3]. If you want a course on a particular stack, GeeksforGeeks's listings name several, such as a MERN Full Stack course [2]. If you want to spend nothing, Exercism's page says it is 100% free, forever [1], and AnatomyOf is free with no account [3]. For other needs, check the sources given here, because the facts available for both Exercism and GeeksforGeeks are limited.
