The short answer

Codecademy's sources given here cover its prices. A Basic option is always free ^[1], one paid option costs $14.99 a month billed annually or $29.99 billed monthly ^[1], and another costs $19.99 a month billed annually or $39.99 billed monthly ^[1]. The facts used here do not say what Codecademy teaches, so this page says little about its content.

GeeksforGeeks's sources describe a DSA and System Design course for learners from beginner to advanced levels ^[2].

AnatomyOf shows an example source file with color-coded callouts linked to the exact lines they explain ^[3]. It is free and needs no account ^[3].

Each source names a different need. GeeksforGeeks's sources name a System Design course ^[2], AnatomyOf's claims name annotated example code ^[3], and the Codecademy facts used here name its prices only ^[1].

What Codecademy and GeeksforGeeks are built for

The Codecademy facts used on this page are all about cost, so this section can say nothing about its lessons beyond its plans. Check its own course list before you choose.

GeeksforGeeks's sources describe a DSA and System Design course for learners from beginner to advanced levels ^[2]. A separate System Design course covers high-level design, scalability and distributed systems ^[2].

The course pages on each site are the place to confirm what each course covers before you start.

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].

Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations ^[3]. The same annotated format extends to non-code concepts such as an email and a CI pipeline ^[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 a shareable address ^[3].

The site has light and dark themes and works on phones, where you tap to pin a callout ^[3]. It runs in any reasonably current desktop or mobile browser ^[3].

Pricing and fees

Codecademy's Basic option is always free ^[1]. One paid option costs $14.99 a month billed annually or $29.99 billed monthly ^[1].
