Pact vs Tars: What are the differences?

What is Pact? Fast, easy and reliable testing for your APIs and microservices during development. It is a code-first tool for testing HTTP and message integrations using contract tests. Contract tests assert that inter-application messages conform to a shared understanding that is documented in a contract. Without contract testing, the only way to ensure that applications will work correctly together is by using expensive and brittle integration tests.

What is Tars? A high-performance RPC framework. It is an open-source microservice platform. It contains a high-performance RPC framework and a service management platform. Based on Tars, you can develop a reliable microservice system efficiently It is designed for high reliability, high performance, and efficient service management. By significantly reducing system operation work, developers can focus on business logic and meet fast changes of user requirements..

Pact can be classified as a tool in the "Microservices Tools" category, while Tars is grouped under "Remote Procedure Call (RPC)".

Some of the features offered by Pact are:

  • Support for JavaScript, JVM, .NET, Python, Go, Ruby, PHP, Swift and more
  • Get fast, reliable feedback on the compatibility of your integrations
  • Ensures all your services are compatible with each other before you deploy

On the other hand, Tars provides the following key features:

  • Microservices platform
  • Multiple programming languages supporting
  • High performance
