Postbox is a tool to analyze HTTP POST multipart/form-data requests. It captures and displays all the data in the request, rendering the parts of the payload that can be displayed in the browser (images, PDFs, etc.)

Here's how it works:

• Create a box

• POST data to the box's URL

• View the box in a browser

• DELETE the box

Boxes are publically accessible, but hard to find by random users on the internet as they're identified by UUIDs. Undeleted boxes are automatically deleted after 6 hours.
