Web Apps of the Future

Web Apps of the Future

The ideal app is peer-to-peer, offline, and decentralized. Apps should protect users from censorship, the addition of user-hostile features, and data loss due to business failure. Good news! The future is here early; it's possible to build a service like this today, using WebRTC, Service Workers, Web Crypto, and replicating databases. Welcome to the future!
