The Open Source Firebase Alternative with GraphQL.

Nhost is an open-source Firebase alternative that provides a complete backend infrastructure with GraphQL API, PostgreSQL database, authentication, file storage, and serverless functions. It combines the power of Hasura for instant GraphQL APIs with built-in authentication and storage, offering developers a fully open-source backend solution they can self-host or use as a managed platform.
Nhost is ideal for full-stack developers, startups, and teams who want a Firebase-like experience with open-source components and the flexibility to self-host. It's particularly suited for developers who prefer SQL databases and GraphQL APIs, and want complete control over their backend infrastructure.
