  "description": "Dynoxide is a DynamoDB-compatible database engine written in Rust and backed by SQLite. One engine runs as a local HTTP server (a drop-in for DynamoDB Local), as an in-process library for Rust and iOS, as a WebAssembly build for the browser, and as an MCP server with 34 tools for coding agents. It starts in about 2ms, downloads at about 3 MB, and needs no Docker or JVM.",
