All records are randomly combined from small built-in lists and are fictional. Email addresses use the reserved example.com domain. Data is generated in your browser; the values are random but not cryptographically secure.

FAQs

Answers to the most common devtool questions.

Is everything client-side?

Most dev tools run entirely in your browser. For tools that need server help, requests are encrypted.

Do you store my data?

No. Inputs are kept in-memory in your session. Nothing is logged for formatting or validation tools.

Can I use keyboard shortcuts?

Yes. Common shortcuts like Ctrl/Cmd + A/C/V work. Some tools also support Ctrl/Cmd + Enter to run.

Will formatting change my content?

We preserve semantics. Converters and formatters avoid altering values, only structure and spacing.

How do I report an issue?

Use the feedback link in the header or share a sample payload. We typically patch fixes within a day.
