Holocron is a high-performance offline intelligence console built in Go.
It provides instant querying of the asn.db dataset — a compact SQLite3 database
containing Autonomous Systems, owners, ranges, network types, and locations.
Designed for analysts, penetration testers, researchers, and engineers,

Holocron runs a local Go HTTP server and performs SQLite queries directly against
