Best for

Developers who keep opening random websites for small text and data tasks.

Why it deserves attention

DevToys bundles dozens of small utilities behind one offline app: JSON formatter, base64, JWT decoder, regex tester, hash generators, diff, UUID, timestamps, and image converters. Nothing is uploaded, which matters when the input is a token or production payload. It is a toolbox rather than an IDE, and a few tools are platform-specific or less complete than dedicated utilities.
