Community vote — which would you rather vibe code?
The case on Discord
Keep paying or use existing chat tools; the multi-party SFU voice routing and WebSocket gateway infrastructure required make this a serious undertaking that defeats solo vibecoding.
Hardest parts
- Real-time WebSocket connection state management across massive concurrent user counts
- Distributed Selective Forwarding Unit (SFU) architecture for multi-party WebRTC audio/video routing
- Complex hierarchical permission evaluation for channels and categories
The case on Slack
Build a scaled-down personal web clone with chat, channels, and LLM search, but keep paying for Slack because real-time multi-tenant sync and enterprise scale take months.
Hardest parts
- Maintaining low-latency state synchronization across thousands of concurrent WebSocket connections and multi-device presences
- Implementing permission-aware vector and keyword search (RAG) that instantly filters query results against channel membership ACLs
- Handling offline state queues, message delivery retries, and optimistic UI updates seamlessly across client wrappers
