About Us
About CodoKit — Free, Private, Browser-Based Developer Tools
CodoKit is a free, lightning-fast collection of 20+ developer tools — formatters, encoders, generators, and text utilities — built to be the kind of toolkit we wished existed: minimal, honest, and relentlessly private.
Our Mission
The web is full of developer tools, but most of them are bloated, ad-saturated, and quietly send your input to a server you've never heard of. We built CodoKit to be the opposite: a single page where you can format messy JSON, decode a JWT, generate a UUID, or convert a Unix timestamp — and know with certainty that the data you pasted never left your browser.
We believe developer tools should be a public good. They should load instantly on a phone in a subway tunnel. They should work the same in 2010 Internet Explorer as in 2026 Chrome. They should never demand an account, never rate-limit a frustrated engineer at 2 AM, and never silently break because some analytics script hung. CodoKit is our attempt to deliver exactly that.
What Makes CodoKit Different
Core principles behind every tool we build
1. Private by design
Every tool on CodoKit runs entirely in your browser. There is no backend API that receives your input, no database that stores it, no log file that records it. When you paste a JSON payload into the formatter, your browser's JavaScript engine parses it and writes the result into the output box — that's it.
2. Fast by default
CodoKit is built on Astro, a web framework that ships zero JavaScript by default. Most pages contain less than 50 KB of total JavaScript — and only the specific library that powers the tool you're using.
3. Free forever
Every tool is free with no signup, no rate limits, no upsell, and no "premium tier." We pay for hosting with non-intrusive display advertising through premium ad networks. We never sell or collect user data.
4. Open standards
Every tool uses an industry-standard library — Prettier, jose, sql-formatter, the native Web Crypto API — rather than a hand-rolled parser. The output matches what you get from running the same library locally.
Numbers at a Glance
Who Built This?
CodoKit is built and maintained by a small team of working software engineers who got tired of cluttered, ad-stuffed tool sites. We work on it in our spare time because we use it ourselves every day.
How We Make Money
Server hosting, domain registration, and maintenance cost money. We cover these with non-intrusive display ads through premium networks (Ezoic, Mediavine, or AdSense). No popups, no malware, no infinite scroll traps, and no dark patterns.
