## What it is
Space Cloud is a Kubernetes-based open-source serverless platform that generates instant GraphQL and REST APIs over databases like MongoDB, PostgreSQL, MySQL, and SQL Server, with realtime subscriptions, file storage, event triggers, and fine-grained access control. It also provides deployment, service mesh, and autoscaling capabilities for microservices, acting as a self-hosted Firebase/Heroku alternative.

## Use cases
- generate graphql apis from my database without writing backend code
- self-hosted firebase alternative on kubernetes
- add realtime subscriptions to database queries
- build a backend for my app without writing server code
- trigger serverless functions on database changes
- secure database apis with fine-grained access control
- deploy and autoscale microservices on kubernetes
- upload and manage files in s3 from the frontend

## When to choose
- you want instant CRUD/realtime APIs over MongoDB, PostgreSQL, MySQL, or SQL Server without backend code
- you need a self-hosted BaaS with auth integration, file storage, and eventing on Kubernetes
- you want centralized authorization rules decoupled from application code
- you need cross-database joins via GraphQL

## When to avoid
- you need active development and new features - the project is explicitly in maintenance mode
- you are not using Kubernetes and just want a simple API layer - a direct gateway deployment is possible but limited
- you prefer actively maintained alternatives like Hasura or WunderGraph
- you need databases outside its supported list (MongoDB, PostgreSQL, MySQL, SQL Server)
