Could you build this?
Partial The client UI and API layer are simple, but operating a breach checker requires compiling, hashing, and querying hundreds of millions to billions of compromised email records without leaks.
What it would actually take: The architecture requires a massive database (such as PostgreSQL with bloom filters, or ClickHouse/RocksDB) indexing billions of breach records via k-anonymity SHA-1/SHA-256 prefixes like HaveIBeenPwned. The hardest part is curating, deduplicating, and securely maintaining terabytes of leaked dark web and public data breach dumps. This requires specialized data engineering and security infrastructure.
