Partial The web UI and payment flow are trivial, but the core product depends on access to a proprietary or aggregate database of billions of leaked breach records.
What it would actually take: The front end is standard Next.js with Stripe integration, querying a backend backed by an Elasticsearch or ClickHouse cluster indexing billions of compromised credentials. The difficult part is aggregating, normalizing, de-duplicating, and securing hundreds of gigabytes of underground breach datasets, similar to HaveIBeenPwned.
