E2EE connections between trusted devices

CNSPRCY aims to tightly integrate your personal computing devices (i.e. desktop, laptop & phone but not wearables) with each other. It will provide a replicated eventually-consistent database, the ability to send encrypted messages, and it will always (unless it is impossible) know how to connect to your other devices!

It does not rely on third parties or blockchains, and it will not make your devices carry other people's data. Devices will simply connect directly to each other, forming a mesh and adapting to the conditions of the underlying network using a variety of protocols.

CNSPRCY provides a CLI application and exposes an IPC API, allowing you or your applications and scripts to synchronize data (asynchronously) or exchange messages (synchronously) with your other devices. These messages can then trigger scripts and execute applications on the receiving device. With these tools, it will be easier to write robust, private, offline-first, P2P software than it is to implement a centralized client-server architecture.
