DataHunter
Data tools that run in your browser
Free editors for JSON and Markdown: no sign-up, no uploads. Your files stay on your device, and the work you started is waiting when you come back.
What works right now
Four tools, open to everyone. More are on the way.
JSON editor
Format, check and fix JSON. Errors are shown with the exact line.
Markdown editor
Write Markdown and see the result next to it as you type.
QR code generator
Create custom QR codes for URLs, contacts, WiFi and more.
XNote
Send secret messages that self-destruct. Encrypted end-to-end, nothing is stored on a server.
File transfer
Send a file straight to another device, with no upload to a server.
Why it is worth using
Nothing leaves your browser
Files are neither uploaded nor stored on our servers. Editing happens entirely on your device.
Your work is not lost
Recent documents are kept in the browser, so you can return to what you were doing.
No sign-up
Open the page and start working. No account, no email, no limits.
What comes next
DataHunter is growing into a platform for collecting and processing data: webhook capture, social media parsers, storage and a data marketplace.
