What you can do
DevUtility Lab helps you format JSON, convert Base64, inspect JWTs, test regex and generate developer helpers. Start from the main tool or choose a related task; the basic result stays available without mandatory signup.
How it works
Developer tools process the entered text and show formatted, decoded or generated output immediately.
Privacy and limits
Prefer local browser processing for pasted snippets and tokens.
Do not paste secrets you would not share with a web page, even when a tool runs locally.
