Show HN: Falcon – Chat-first communities built on Bluesky AT Protocol
JohannaWeb Tuesday, February 24, 2026I’m building a chat-first community app that uses Bluesky’s AT Protocol for identity.
Current architecture: - Electron client - Spring Boot backend (monolith) - REST for servers/channels - Planning WebSocket-based messaging
As a solo builder, I’m trying to balance simplicity with future scalability.
At what point would you introduce: - a separate WebSocket gateway - pub/sub (Redis, etc.) - or keep everything in one Spring app until it breaks?
Curious how others approached real-time chat systems early on.
