Top 25 Free Programming Books in 2026
Programming books are expensive — a single new O'Reilly title often costs $40–60, and a full learning path can run past $300. The good news: some of the most respected programming books ever written are completely free, released by their authors under open licenses or published openly on the web. This list collects 25 of the best, organized by where you are in your journey.
For complete beginners
Automate the Boring Stuff with Python
by Al Sweigart
The single best first programming book. Free to read online, teaches Python through practical tasks — renaming files, filling forms, scraping websites — instead of abstract theory.
Python Crash Course
by Eric Matthes
A structured, project-driven introduction. Pairs well with Automate the Boring Stuff: read this for foundations, that for practical wins.
Eloquent JavaScript
by Marijn Haverbeke
The classic free introduction to JavaScript and programming in general, with interactive exercises built into the online edition.
Start with exactly one of these, finish it, and build something small before adding more books. Collecting books is not the same as learning.
Leveling up: intermediate essentials
You Don't Know JS
by Kyle Simpson
A free book series that goes deep on how JavaScript actually works — scope, closures, prototypes, async. Read after your first project, not before.
The Linux Command Line
by William Shotts
Free from the author. Every developer eventually needs the terminal; this is the gentlest thorough introduction.
Pro Git
by Scott Chacon & Ben Straub
The official Git book, free forever. Chapters 1–3 cover 90% of what you'll use daily.

by Abelson & Sussman
MIT's legendary text, free online. Harder than everything above, and worth it — it changes how you think about programs.
Specialization: data, ML, and systems
Deep Learning
by Ian Goodfellow, Yoshua Bengio & Aaron Courville
The standard deep learning reference, free on the authors' site. Requires linear algebra and calculus.
