Compose, formerly known as MongoHQ, is a platform that provides managed database services, focusing on delivering databases that are robust, scalable, and easy to use. With its headquarters based in the United States, Compose offers a range of database solutions, including MongoDB, PostgreSQL, Redis, Elasticsearch, and more. The platform is designed to simplify database management by automating operations such as scaling, backups, and updates, enabling developers to focus more on building their applications rather than managing database infrastructure.
