Capsule Packs an Entire Web App and Its Data Into One SQLite File You Send Over AirDrop
Capsule, posted to Show HN on September 15 and up to 342 points, is a Rust and Tauri 2.0 app that bundles an HTML interface, media assets and a local database into a single .capsule file that opens like an app and travels like a document. Data persists either as a localStorage key-value store or through a MongoDB-inspired collections API, with PDFs and images stored in the same file and CSV or JSON export built in. It is a direct rejection of the SaaS distribution model — no account, no server, no subscription — and the same shape as the sudden interest in local-first tools now that an LLM can generate the app itself in an afternoon.
