Nhost

Nhost is an open-source Firebase alternative that provides a fully managed backend platform built on PostgreSQL, GraphQL, and modern open-source tools. Developers get instant REST and GraphQL APIs auto-generated from their database schema, along with authentication supporting email/password, OAuth, magic links, WebAuthn, and one-time passwords. The platform includes S3- compatible file storage with CDN delivery and image transformation, serverless functions deployable as HTTP endpoints, and real-time GraphQL subscriptions. Nhost also offers a local development CLI, GitHub-based automated deployments, an AI toolkit with auto-embeddings and assistants, and managed container services—enabling teams to launch production-ready backends without infrastructure management.

Nhost publishes 11 APIs on the APIs.io network, including authentication API, documentation API, excludeme API, and 8 more. Tagged areas include GraphQL, PostgreSQL, Authentication, File Storage, and Serverless Functions.

The Nhost catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Nhost’s developer surface includes authentication, documentation, engineering blog, pricing, and 14 more developer resources.
