DevToysUnderrated
An offline toolbox for JSON, regex, hashes, and everyday conversions.

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.
