Small tools, no setup
Sometimes you just need to check whether a JSON payload is valid, decode a Base64 string from a log, or see what a URL looks like once it is encoded. Opening an IDE or writing a quick script for that is overkill. These tools load in a second and get out of your way.
Your data stays in your browser
Every tool here runs locally with JavaScript. The JSON you format, the strings you decode and the files you hash are never sent to our server. That matters when you are working with tokens, customer data or internal configs. Even so, it is good practice to avoid pasting live passwords or private keys into any website.
Also useful for developers
- camelCase, snake_case, kebab-case and CONSTANT_CASE converters for renaming variables.
- UUID generator for test IDs.
- Find and replace with regex support.
