All Developer Tools

The developer tools people reach for most often are a JSON formatter, a JSON viewer or tree, a diff tool, a Base64 encoder and decoder, a URL encoder and decoder, a JWT decoder, an HTML or XML formatter, a minifier, a UUID generator, and a regex tester. Every one of those families is listed on this page, and each tool runs entirely in your browser without uploading anything.

Ten examples from this directory are JSON Reader, JSON Diff, HTML Pretty Print, XML Formatter, Base64 to JSON, URL Encode, JWT Decoder, UUID Generator, SCSS Formatter, and the Cloud Cost Calculator. They cover the everyday jobs of reading, comparing, converting, encoding, and estimating that come up in most software work.

This page lists every developer tool on the site grouped by family, such as JSON, XML, HTML, CSS preprocessors, encoding, and cost calculators. Scroll the families to see each tool's name and one-line description, then click through to use it.
