Ditto Extension by Soapbox

A Nostr extension. Log into any Nostr client, and comment on any webpage from your browser.

Ditto Extension is a Nostr signer for your browser. Log into Nostr once, and every Nostr web app you visit can ask the extension to sign on your behalf — no more pasting your nsec into random sites.

Ditto Extension implements the standard Nostr signer API (NIP-07) used by virtually every Nostr web client. When a site calls window.nostr, you get a permission prompt — allow once, always allow, or reject — so you stay in control of exactly what each site can do with your identity.

Comment on any webpage. Ditto Extension can attach a Nostr comment thread to any URL you visit, so any page on the web becomes a place to discuss with the Nostr community.
