NostrComments

Comment freely on every website — without censorship

Comment freely on any website — without censorship, powered by Nostr. NostrComments adds a floating button to every webpage that opens a decentralised comment thread. Comments are stored on public Nostr relays — not controlled by any website, platform, or algorithm. WHY? News websites and social platforms routinely delete or hide comments. NostrComments lets anyone leave a permanent, uncensorable comment on any URL. GETTING STARTED No account needed. Click the button and generate a key in one tap — your identity is a cryptographic keypair stored in your browser. Already use Nostr? Connect your existing wallet (Alby, nos2x) instead. FEATURES - Works on any website - No account, server, or sign-up required - Built-in key generation — no external wallet needed - Optional password encryption of your key at rest - Portable identity — copy your key as nsec / npub for any other Nostr app - Upvote / downvote with community auto-hide - Mute users, and mute any word or phrase you choose - "New" badges for comments posted since your last visit - Reply threads, notifications, search, and sort (newest, oldest, most upvoted) - Zap comments with Lightning - Inline images and video, dark mode, custom relays - Per-site disable option - Open source: github.com/briskness-byte/NostrComments DATA DISCLOSURE NostrComments has no server and the developer receives no data. There is no account, no tracking, and no analytics. Nothing is transmitted until you explicitly enable the extension on a one-time disclosure screen. After that: - Loading and posting comments: the current page URL, your comment or vote, and your Nostr public key are sent to the public Nostr relays you have configured. These are independent third-party servers, not operated by NostrComments. - Zapping (optional): if you choose to send a Lightning tip, your browser contacts the recipient's Lightning provider to fetch an invoice, and your own wallet pays it. That provider sees the request, including your IP address. No payment code is bundled and no money passes through the developer. - Stored on your device only, never transmitted: your key (optionally encrypted with PBKDF2 + AES-GCM), relay list, muted users and words, per-site disable list, theme, your consent choice, and a list of the last 300 pages where you opened the panel, used to mark comments as "new".
