Framework invented by Andrey Sitnik for building optimistic, real-time web UIs. Treats modern web apps as distributed systems with clients and servers synchronizing events over WebSockets. Provides a standalone server, a JavaScript client that wraps Redux with a compatible API, an open protocol (so other technologies can implement components), built-in offline support (pings + event queueing), standard UI widgets for network state, event ordering via timestamp plus incrementing counter, automatic conflict resolution via last-write-wins, and an 'undo' event for server-error rollback. A Logux proxy component forwards events to any HTTP backend and exposes an endpoint for the backend to synchronize events back — effectively a two-way HTTP gateway.
