Mountebank is a powerful open-source tool used for creating mock servers and service virtualization. It allows developers to simulate various types of APIs, services, and protocols to facilitate testing and development. With Mountebank, you can define custom behaviors, responses, and conditions for your mock services, making it ideal for testing complex scenarios and edge cases.
Nock is a powerful HTTP mocking and expectations library for Node.js. It allows you to simulate HTTP requests and responses, making it ideal for testing code that interacts with external APIs or services. With Nock, you can define custom HTTP endpoints, set up response behaviors, and verify that your code makes the expected HTTP calls.

Functionality
Mountebank is a powerful stubbing and mocking library that allows you to create and manage mock services. It provides the ability to create custom HTTP, TCP, and SMTP servers for testing, mocking, and stubbing. Nock, on the other hand, is a library specifically designed for mocking HTTP requests and responses. It intercepts outgoing HTTP requests and allows you to define customized responses. While Nock is focused solely on HTTP mocking, Mountebank provides a broader range of functionality with support for multiple protocols.
Ease of Use
Nock is known for its simplicity and ease of use. It provides a straightforward API for intercepting and mocking HTTP requests, making it easy to set up and use in tests. Mountebank, on the other hand, has a steeper learning curve due to its broader range of features and protocols. It requires more configuration and setup to create and manage mock services. However, once set up, Mountebank provides more advanced options and flexibility.
Integration
Nock integrates seamlessly with popular testing frameworks like Mocha and Jest. It allows you to easily mock HTTP requests in your unit tests. Mountebank, on the other hand, is more suitable for end-to-end or integration testing scenarios where you need to create complete mock services. It can be integrated into different test runners and frameworks to simulate complex service interactions.
Scalability
Mountebank is designed to handle complex service interactions and can simulate multiple services working together. It supports the creation of dynamic responses and behaviors, making it suitable for testing complex scenarios. Nock, on the other hand, is more focused on individual HTTP requests and responses, making it a lightweight option for simpler use cases. If you need to simulate complex service interactions or test multiple services together, Mountebank is a better choice.
Community and Maintenance
Both Mountebank and Nock have active communities and are actively maintained. Mountebank has been around for longer and has a larger user base. It has regular updates and releases. Nock is also well-maintained and has a strong community. When it comes to community support and maintenance, both packages are reliable choices.
