SayDeploy is published by LunarWerx, which makes some of the tools compared here.

Exercism says it is 100% free, forever, and it pairs coding exercises with human mentoring. [1] [1] AnatomyOf shows example source files with color-coded callouts that explain each line, so it is a different way to learn syntax: reading rather than solving. [2]

AnatomyOf: annotated example files for reading syntax

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] Entries have shareable links, so you can send a colleague the exact example you mean. [2] It highlights code with Shiki, the engine VS Code uses. [2]

It has light and dark themes and works on phones, where you tap to pin a callout. [2]

AnatomyOf is free, with no account and no paid tier. [2] It is open source under the MIT License. [2] It runs in any reasonably current desktop or mobile browser. [2] There is nothing to install. [2] It sends one anonymous visit ping per browser session on page load, and the README says it collects anonymous usage statistics. [2]

How to pick the right Exercism alternative

Choose AnatomyOf when the goal is to read an example file and see what each line does through callouts. [2] Check whether you want a minimal and a verbose version of the same example. [2] Check whether you are comfortable learning from examples and explanations rather than exercises to submit.

Stay with Exercism when the goal is practice with exercises and human mentoring. [1] [1] Check whether the CLI-first approach suits your setup. [1]

Check how each option handles the language you want to learn. Exercism says it offers 84 programming languages. [1] AnatomyOf lists languages sorted by TIOBE Index rank, can switch to A-Z, and has instant search. [2]

If you read on a phone, AnatomyOf works on phones, where you tap to pin a callout. [2]

Using both is an option: read an annotated example first, then practice on exercises. The facts here do not say whether either one teaches the other's material, so check the language you need on each.
