Developers rely on a small set of tools for developers every day: formatting JSON, encoding Base64, testing regex, generating passwords, and comparing text. Having them free and in the browser means no context switching and no installs.
In 2026, the best dev tools run client-side for privacy, work offline when possible, and support common tasks without signup. A single hub for JSON formatter, Base64 encode/decode, regex tester, text compare, and password generator covers most ad-hoc needs.
Explore our Developer tools category: format and validate JSON, encode and decode Base64, test regular expressions, compare two texts, and generate strong passwords—all free and instant.
