Zapstore: Permissionless app store powered by nostr and your social graph. No gatekeepers, no censorship — publish directly to users, discover apps through communities you trust. Your device, your rules. #SovEng https://zapstore.dev/

Your website shouldn't depend on someone else's server, someone else's terms of service, or someone else's permission. nsite fixes this. It's a website hosted entirely on Nostr relays and Blossom servers. Your npub is your domain. Your keys are your credentials. No hosting provider can rugpull you because there is no hosting provider. The raw data lives on Blossom, the file mapping lives on relays, and anyone can spin up a gateway to serve it. Redundant at every layer. nsite came out of in Madeira, where builders turn freedom tech ideas into working code. https://nsite.run
