RESTHeart connects to MongoDB and exposes a simple REST API to read and write data via plain HTTP requests.

You don’t need to write a single line of backend code for Mobile Apps and Angular, React, Vue or other Single Page Application frameworks.

RESTHeart is dual licensed under the open source GNU AGPL v3.0 and the business friendly RESTHeart Commercial License.

RESTHeart is written in Java and is build on top of the Undertow high performance, non-blocking HTTP server.

We created RESTHeart because:

  1. All modern applications require a common set of basic REST APIs;
  2. Many recurrent non-functional requirements, like authentication and authorization, HTTP protocol support, etc… can be solved once for all;
  3. We were tired of configuring and maintaining complicated application servers.

The founding ideas around RESTHeart are:

  1. The key architectural trends in software development are microservices architecture and NoSQL databases
  2. Developers primarily need a backend to easily store and retrieve content, as these days Single Page Applications and Mobile Apps are moving the business logic to the client side;
  3. Modern Apps want consuming a REST API and use JSON as the message format (goodbye XML and RPC);
  4. MongoDB is the leading NoSQL database for Web and Mobile apps; it’s lightweight, fast, schema-less and uses JSON.
  5. Having an out-of-the-box backend, we can better focus on what matter the most: the User Experience;
  6. Docker is emerging as the de facto standard to package and distribute applications.


  • Setup in minutes the lightweight and fast microservice with support for MongoDB and AWS DocumentDB; available also as a Docker image
  • Built on standards, like HTTP, JSON, REST, JSON and JSON Schema
  • Read JSON documents with GET requests, specifying MongoDB queries and projection options; deal with large result sets with pagination
  • Create, modify and delete JSON documents with POST, PUT, PATCH and DELETE requests. Use bulk requests to deal with multiple documents in one shot
  • Out-of-the-box User Authentication and Authorization
  • Store and serve binary data with GridFS support
  • Define and execute Aggregations, supporting both map-reduce and aggregation pipelines
  • Execute requests in multi-document ACID transactions
  • Access real-time data changes via Websocket Change Streams
  • Create dbs, collections and indexes with Data Model API
  • Validate requests with JSON Schema
  • Extend RESTHeart via Plugins: transform, check requests and responses, keep data secure with authenticators and authorizers, executes WebHooks after a request completes, implement Web Services in minutes, serve Static Resources (such as HTML, CSS, images and JavaScript)
  • Define Relationships so that documents automatically include hyperlinks to referenced data
  • Forget about HTTP details with automatic support of Cross-origin resource sharing, Web Caching and HTTP ETag to avoid ghost writes
