About

A curated map of the internet for developers.

Corpus Stack brings together the best free resources for learning, building, and exploring technology. Every entry is verified against three non-negotiable criteria before it earns a place.

“Access to knowledge is a right, not a privilege.”

— Aaron Swartz

The three tenets

Strictly free

No paywalls, no trials, no hidden costs. Every resource in the archive can be accessed completely free, without a credit card or a subscription.

Location-agnostic

Content must be accessible globally without regional restrictions or institution-only emails. Knowledge should not depend on where you were born or which school you attended.

High utility

Actionable material: documentation, courses, interactive tutorials, sandboxes, and verified references. Content that helps you learn or build.

Why it exists

The best free technical resources are scattered across the internet. Finding them takes time, and knowing which ones are worth your attention takes even more. Corpus Stack brings them together in one place.

Every resource is chosen by hand, checked against the three tenets, and described in plain language.

This is a living archive. Resources are added regularly, verified frequently, and removed when they no longer meet the standard.

How resources are added

The archive is open-source and community-driven. Anyone can suggest a resource. Every suggestion goes through the three tenets before it appears.

If you know a free resource that belongs here, submit it. If you find a broken link or something that no longer qualifies, report it. That's how the archive stays honest.
