+# Limbo 
+
+Limbo is a _work-in-progress_, in-process OLTP database engine library written in Rust that has:
+
+* **Asynchronous I/O** support on Linux with `io_uring`
+* **SQLite compatibility** [[doc](COMPAT.md)] for SQL dialect, file formats, and the C API
+* **Language bindings** for JavaScript/WebAssembly, Rust, Go, Python, and [Java](bindings/java)
+* **OS support** for Linux, macOS, and Windows
+
+In the future, we will be also working on:
+
+* **Integrated vector search** for embeddings and vector similarity.
+* **`BEGIN CONCURRENT`** for improved write throughput.
+* **Improved schema management** including better `ALTER` support and strict column types by default.
