ActivityPub Viewer

A small tool to view real-world ActivityPub objects as JSON! Enter a URL or username from Mastodon or a similar service below, and we'll send a request with the right Accept header to the server to view the underlying object.

Note that sometimes you need to add something extra to pretty URLs! Like even if the account is visible at https://masto.example.com/username, you might need to go to https://masto.example.com/users/username or similar.
