Para - an open-source, general-purpose, backend framework for the cloud.About ParaPara was designed to be a simple and modular backend framework for object persistence and retrieval. It helps you build applications faster by taking care of the backend. It works on three levels - objects are stored in a NoSQL data store or any old relational database, then automatically indexed by a search engine and finally, cached.

About Para

Para was designed to be a simple and modular backend framework for object persistence and retrieval. It helps you build applications faster by taking care of the backend. It works on three levels - objects are stored in a NoSQL data store or any old relational database, then automatically indexed by a search engine and finally, cached. Para is also multitenant and has a clean and easy-to-use JSON API.

The name "pára" means "steam" in Bulgarian. And just like steam is used to power stuff, you can use Para to power your mobile or web application backend.

Why use it? Because it's open source, well documented and tested and it's just easier to use than most frameworks out there.

It's free to get started!
