A developer shares their journey building Outcrop, a knowledge base alternative to Notion, using Rust for performance and simplicity. The project includes custom implementations of a Zanzibar-inspired authorization system, a search engine using tantivy with sub-millisecond latency, and a Rust port of ProseMirror for real-time collaborative editing. The architecture prioritizes speed through in-memory authorization checks, integrated search with permissions, and microsecond-level document processing. The product targets software teams and aims to launch within six months at €10 per seat.
