Chatra
Chatra combines an embeddable JavaScript chat widget with an agent dashboard and basic e-commerce hooks to display live cart contents. The core websocket messaging loop and live visitor tracking can be built in days using Supabase Realtime or Socket.io. The primary friction is maintaining reliable mobile push notifications and agent desktop applications.
