Developer Tools

Utilities for developers: identifiers, patterns, simple minifiers and formatters.

Small, free utilities for everyday web development: beautify or minify CSS, JavaScript and HTML, test a regular expression against sample text, or generate a UUID. Each one does a single job, shows the result in the same tab, and is ready to copy back into your project. These developer tools run entirely in your browser tab — no IDE plug-ins to install, and no code is sent to a server.

Reach for the CSS Minifier before deploying a stylesheet, the JavaScript Beautifier when a minified bundle needs reading, the Regex Tester while a pattern is still misbehaving, and the UUID Generator for test data and database keys. Front-end developers and QA testers doing quick one-off jobs are the audience. Formatting JSON, XML or HTML, or encoding Base64? Those jobs live in the text converter section. Checking meta tags or a sitemap? See the free seo tools instead.
