A developer explored the benefits and drawbacks of local-first architecture for solo applications, particularly when using Conflict-free Replicated Data Types (CRDTs). For a note-taking app, local-first architecture significantly improved perceived latency to zero and increased user retention by enabling offline functionality and seamless syncing across devices. However, for a commerce dashboard with a single user and infrequent writes, the complexity and overhead of CRDTs like Yjs and Automerge proved unnecessary, costing extra development effort without providing tangible user benefits. The key determinant for adopting local-first and CRDTs is whether multiple users or devices will concurrently edit the same mutable state while potentially offline. AI
