AppFlowy

An open-source, privacy-first Notion alternative built with a Rust core and Flutter frontend, designed local-first with optional cloud sync. Its standout trait is a clean native-performance architecture instead of an Electron/web wrapper.

βš™ Full Stack

Rust core engine (data storage, sync logic) with a Flutter frontend for desktop/mobile/web clients; the optional AppFlowy Cloud sync server is a separate Rust service backed by Postgres for multi-device/multi-user sync.

πŸ“ˆ Scaling Analysis

The local-first design means most compute happens client-side, so the server component only needs to handle sync/conflict-resolution traffic; AppFlowy Cloud is newer and less battle-tested at scale than the mature local client, so multi-tenant server deployments are a comparatively higher-risk area.

πŸš€ Running on Nexlayer

Only the AppFlowy Cloud sync component is server-deployable on Nexlayer β€” app pod plus `postgres.pod:5432` β€” the actual client is a native Flutter desktop/mobile app, not something hosted per-pod. Treat this as a backend-sync-service deploy rather than a full app deploy.
