About Coders Hub

Coders Hub started as a programming blog. It's now a catalog of 411 focused utilities — formatters, converters, generators and analysers — built to run in your browser wherever possible.

How the tools are built

Every tool implements the same internal contract: metadata, inputs, outputs, an engine and its own SEO surface. That means navigation, search, related tools and structured data are generated from the tool itself rather than hand-maintained. Adding a tool adds its page, its category listing, its command-palette entry and its schema markup at the same time.

Browser APIs, and a small relay where needed

Text and JSON transforms are plain JavaScript. Images use Canvas and the File API. Hashing and IDs use Web Crypto. Heavy work moves to Web Workers. Most of what you paste or drop stays in the tab — which is why most tools keep working with the network off. A handful of network tools (DNS lookup, URL fetch, performance checks, redirect analysis, text-to-speech) call a small server relay to reach other servers on your behalf; those tools say so on their own page.

No accounts

Favourites, history and preferences are stored in your browser's local storage. There's no sign-up, no paywalled tool and no API key to request.
