Show HN: Syncular – offline-first SQL sync with TypeScript and Rust cores

Syncular is an offline-first SQL synchronization framework with TypeScript and Rust cores that allows clients to maintain a local SQLite database while syncing changes through an optimistic outbox to a server-authoritative commit log. The system is spec-first with conformance testing between the two language implementations, supporting browsers via OPFS, native applications, and multiple frameworks including React, Tauri, and React Native. Key features include end-to-end encryption per column, CRDT merging with Yjs, and comprehensive fault-injection testing.
