A developer built Capsule, a single-file SQLite-based application format that embeds HTML assets and data into one portable .capsule file. It offers localStorage-like and MongoDB-inspired APIs for data persistence, along with optional AI model integration. The tool prioritizes privacy with strict permission models and plans to open-source its file format specification at version 1.0.
