About Essential Dev Tools

Free tools for everyday website and development tasks.

Small tools that do one job well

Essential Dev Tools combines eight browser utilities with four public website detectors. There is no account, subscription, or database required to use the tools.

Browser utilities

Format JSON, encode and decode Base64 or URL components, convert HTML entities, generate UUIDs, convert HEX colors, change text case, and count words. These actions process your input locally in your browser.

Website detectors

The Shopify theme detector, WordPress theme detector, WordPress plugin detector, and website technology checker fetch the public page you submit. They inspect HTML, response headers, and, where relevant, public WordPress theme stylesheet metadata. Each report shows its evidence and known limitations.

How this site is funded

The planned funding model is relevant advertising and affiliate offers. Advertising and commission-based referral tracking are not currently active. Regular vendor links do not affect detection results.

Crawling policy

Read how the scanner accesses public websites. The scanner respects robots.txt and does not log in, bypass verification challenges, or access private administration APIs.
