What to send us
If something is factually wrong, outdated, or misleading — send us the page URL, the specific claim, and a source. We take accuracy seriously and will investigate every report.
Missing a language, concept, or project? Have an idea for a better explanation? We read every suggestion — many pages exist because a reader asked for them.
Found a 404, broken code block, or layout problem? Tell us the URL and what's wrong. These get fixed fast.
General questions about the site, what we're building next, or just to say hello — all welcome.
About us
The Codex Coding is built by a small team in Mumbai, India. We're programmers who got tired of the best technical education being behind paywalls or scattered across unreliable sources. The site is free, carries no ads, and requires no account — and that will never change.
We're part of The Codex, a broader project building reliable free reference knowledge across disciplines.
