SlothDB is an embedded, columnar SQL database written in C++ that runs everywhere including in the browser via WebAssembly, with a focus on performance and ease of use. It uniquely combines a fast query engine, live views over growing files, and an optional natural-language-to-SQL feature using local LLMs, all in a small binary with stable ABI. Interesting for its competitive benchmarks against DuckDB, particularly in JOIN performance and WASM size.

Target audience: backend devs, data engineers, devops
