    Project mention: Macaroni – a single HTML file messenger | news.ycombinator.com | 2026-06-10

    Nice idea. I would have expected it would use WebRTC for p2p client-to-client connection. A noted related project is Trystero [0] that uses all sort of external services to allow client-to-client discovery (such as Nostr, BitTorrent, Supabase etc.) - maybe a future project to combine the two.
