Powerful Building Blocks

Dapr enables easy, event-driven, stateful, microservices development.

No Limits

Dapr works with any programming language - on any cloud or edge.

Open API

Dapr provides consistency and portability, via standard open APIs

Open Source

Dapr is an open source and vendor neutral project.

Dapr is a portable, event-driven runtime that makes it easy for developers to build resilient, microservice stateless and stateful applications that run on the cloud and edge and embraces the diversity of languages and developer frameworks.

Cloud-native development:

Distributed App Challenges

  1. Hard to incrementally migrate from existing code to a microservices architecture.
  2. Many programming model runtimes have narrow language support and tightly controlled feature sets.
  3. Event-driven architectures and state handling are complicated making them difficult to scale.
  4. Many runtimes only target specific infrastructure platforms with limited code portability across clouds and edge.

With Dapr:

Streamlined Microservices

  1. Dapr enables developers using any language or framework to easily write microservices, providing industry best practices to solve distributed systems problems.
  2. Dapr provides consistency and portability through open APIs and extensible components that are community-driven.
  3. Dapr handles state, resource bindings and pub/sub messaging, which enable event-driven, resilient architectures that scale.
  4. Dapr is platform agnostic and runs on any infrastructure, including public clouds and edge devices with its open APIs.
