Hasura

Hasura is a tool that automatically creates a GraphQL API from your existing data sources. You connect your databases (like PostgreSQL, MySQL) or REST APIs, and Hasura builds a ready-to-use, real-time GraphQL backend for you. This means you can start querying your data through a modern API without writing the boilerplate code typically required for such a system.

It works by introspecting your connected data sources and generating a GraphQL schema that matches your data structure. A key feature is its ability to combine multiple databases and services into a single, cohesive GraphQL endpoint. It also handles real-time data subscriptions out of the box, so your app can receive live updates. For performance and scale, Hasura offers a Data Delivery Network, which is a globally distributed network designed to serve your API with low latency.

This tool is a major time-saver for developers and teams building web or mobile applications. It's especially useful when you need to prototype quickly, add real-time features like live dashboards or chat, or manage a complex data landscape from a single API. By handling the heavy lifting of API construction, security, and performance, Hasura lets developers focus more on building the frontend and business logic of their applications.
