hadlink

High-assurance URL shortener with formally verified core logic

Servicefreeglobal

hadlink is a URL shortener and redirect service whose core logic is formally verified in SPARK/Ada, aimed at contexts that need the same assurance rigor as safety-critical or embedded software. It's for organizations that can't accept an ordinary web-framework shortener's lack of formal correctness guarantees.
