AI Analysis
●●●BangerWizardryBig BrainSlick
Runs the same Rust core in the browser via WebAssembly with zero server dependency.
Strengths
- •Cap'n Proto RPC and WebSocket subscriptions enable true real-time streaming without polling overhead.
- •Browser-native WASM build allows local-first map apps to run entirely client-side.
- •Durable webhook delivery with SQLite-backed outbox ensures at-least-once event reliability.
Weaknesses
- •Geofencing logic requires defining hooks as code, which may deter non-technical users.
- •Single-leader replication model limits write scalability compared to multi-leader alternatives.
