Xata is a combination of a relational database, an analytics engine, and a free-text search engine. All made simple by a spreadsheet-like UI and a single powerful data API, with granular security, zero-downtime migrations, subscriptions, ACID transactions, and caching built-in. If you don’t worry about servers when deploying your application, why should you worry about servers (or nodes, or clusters) when using a database service? The simple global RESTful API for inserting, querying, aggregating, and searching makes Xata the perfect companion for Serverless and No-Code/Low-Code development platforms. Xata allows you to iteratively build your database schema as you add sample data, all via a spreadsheet-like UI. You can add new tables, columns, data, and create queries and views. It then gives you code samples ready to be used in your application. This gives you flexibility as you develop and, as the application grows, the strict schema keeps your data safe and correct.
