Why Choose Mockd Over Microcks?

Zero Dependencies

Mockd is a single binary. No Java runtime, no Docker, no Kubernetes required. Download and run in seconds, not minutes.

Milliseconds, Not Seconds

Start mocking in <10ms vs 30+ seconds with Microcks. Essential for fast CI/CD pipelines and rapid local development iterations.

20x Lower Memory

Run comfortably on <30MB vs 500MB+. Perfect for resource-constrained environments, laptops, and parallel test execution.

Simple Configuration

Define mocks with simple YAML. No OpenAPI import required, no complex setup. Get productive in minutes, not hours.

True Offline Support

Works completely offline without any external dependencies. No network required to run your mocks locally.

Local Dev First

Built for developers who need fast, lightweight mocking during development. Not everyone needs a cloud-native platform.

When to Use Each Tool

Both tools have their strengths. Here's when each makes the most sense.

Use Microcks when...

  • Kubernetes-first environments where all services run in clusters
  • Contract testing workflows with OpenAPI/AsyncAPI specifications
  • OpenAPI-first development teams with existing spec libraries
  • Cloud-native infrastructure with existing CNCF tooling

Use Mockd when...

  • Local development where speed and simplicity matter
  • Fast iteration cycles without container overhead
  • Multi-protocol mocking without infrastructure complexity
  • Resource-constrained environments and laptops
  • CI/CD pipelines without Kubernetes dependencies
  • Sharing mocks publicly via built-in cloud tunnel
