URLs

A URL shrink ray written in Rust.

Crushes bloated links into compact codes with a stateless codec or a memory-efficient stateful store. No database is required for the algorithmic path, and the sealed index keeps millions of keys in remarkably little RAM.

Small links. Serious systems.

URLs has two paths: a stateless codec that reconstructs links without storage, and a stateful store that produces five-character keys backed by append-only logs, sharding, and a sealed minimal perfect hash index.
