About CodeDoz
Built for developers who'd rather be shipping.
CodeDoz is a free, open space where developers learn, build, and swap knowledge — structured tutorials, honest comparisons, quick-reference cheatsheets, and a growing set of browser-based tools, all in one place. No paywalls, no login walls, no dark patterns. Just the stuff you'd want open in another tab.
What you'll find here
Eight categories cover the full arc of a developer's day — from your first tutorial to the project you ship.
Tools
11 tools, zero installs
JSON formatting, Base64 encoding, regex testing, password generation, hashing, and more — each one runs instantly in your browser, so nothing you paste ever leaves your machine.

Developer Profiles
Real developers, real setups, real stories — a running archive of the people building with CodeDoz, told in their own words, one issue at a time.

Free, always
Every article, cheatsheet, and tool is free to read and use. No paywalls, no premium tier, no account required.
Bilingual by default
Every page ships in English and 中文 side by side, not as an afterthought bolted on later.
Practical over trendy
We'd rather publish a tutorial that solves a real problem than chase whatever's trending this week.
Runs in your browser
Our tools do the work client-side — nothing you paste or type is sent to a server.
