Hasura is an open-source GraphQL engine that automates the process of building scalable and real-time applications. It transforms your databases into a powerful, secure GraphQL API without the need for complex server-side logic. This capability allows developers to quickly and easily leverage their existing PostgreSQL databases for building applications, enabling rapid development and deployment of new features. Hasura supports multiple databases and provides a rich set of features such as authorization control, event triggers, and remote schemas, allowing integration with other APIs seamlessly. Additionally, Hasura can work in conjunction with serverless functions, enabling developers to add custom business logic without managing servers. This rapid API creation helps teams accelerate development cycles, reduce backend workload, and offer a robust solution for building modern applications in a microservices architecture.
