Typesense is an open-source, in-memory search engine, that you can either self-host or run on Typesense Cloud. Typesense focuses on performance by storing the entire index in RAM (with a backup on disk) and also focuses on providing an out-of-the-box developer experience by simplifying available options and setting good defaults.
