Free online developer tools
Small utilities that developers reach for constantly — encoding a string, generating a secure password, checking a value — collected in one place and built to run entirely client-side. Because the work happens in your browser, sensitive input like passwords and tokens never travels to a server.
The category is growing. Right now you'll find a JSON formatter, a password generator, a Base64 encoder/decoder, a URL encoder, a UUID generator, a hash generator, a timestamp converter, an HTML entity encoder, a color converter and a JWT decoder, with more encoders, formatters and generators on the way.
