Could you build this?

No Building an offline-first SQL synchronization engine with dual Rust and TypeScript cores requires complex distributed systems work, conflict resolution algorithms (CRDTs or operational transforms), and database storage engine internals.

What it would actually take: The core requires a cross-platform sync engine written in Rust compiled to WASM/native, interfacing with SQLite via custom extensions or VFS, and tracking changeset deltas. Hard challenges include deterministic conflict resolution, partial replica replication, schema migrations across distributed clients, and low-latency replication over websockets. Requires deep expertise in distributed databases and systems programming.

Discussion

20 comments analyzed.

Competitors mentioned: wa-sqlite, DuckDB-Wasm, Loro, Automerge, Obsidian

Concerns raised: OPFS+SQLite unreliable on Safari/WebKit, Per-row conflict resolution insufficient for complex data models, Browser storage eviction not handled reliably, No tools provided for conflict resolution, risk of incoherent data, LLM-generated code and documentation trustworthiness

Feature requests: Request persistent storage or warn users about unsynced data loss, Ability to view whole transactions and compare server vs local data, Support for queryable CRDTs beyond document columns, Drop-in framework combining local-first sync with P2P/server connectivity
