Show HN: Capsule – Single-file web apps that save their data into SQLite

Capsule allows users to create single-file web applications that store their data in SQLite, bundling the UI, data, and all necessary components into a portable .capsule file. These apps are designed for portability, privacy, and cross-platform compatibility, enabling sharing via messaging apps and offline use. Capsule emphasizes user ownership of data, freedom from cloud accounts, and the ability to modify features through AI prompts or MCP coding tools.
