DNS Worker

Local-First Architecture (OPFS)

Traditional DNS dashboards continually send heavy analytical SQL queries to cloud databases, which increases latency and quickly consumes database billing quotas.

Architecture Highlights

Section titled “Architecture Highlights”
  • Embedded In-Browser SQLite (WASM + OPFS): The dashboard runs a compiled WebAssembly SQLite database inside a dedicated Web Worker, persisting data to the Origin Private File System (OPFS).
  • 0ms Real-Time Queries & Chart Aggregations: Filter tens of thousands of query logs and aggregate dimensions (client IPs, status codes, block reasons, countries) locally in 0 milliseconds.
  • Bidirectional Delta Synchronization: Only newly recorded encrypted logs are incrementally fetched from the server and decrypted locally, minimizing bandwidth and database queries.
