Oh-my-Mock is a Chrome extension developed by Lucas Caljé. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This free extension is designed to cache and mock API (XHR/Fetch) responses.

With Oh-my-Mock, users can easily mock XMLHttpRequest and Fetch requests. The extension automatically caches responses, allowing it to quickly serve cached responses whenever an API is called. This not only enhances the speed of API calls but also reduces the load on the server.

One of the key features of Oh-my-Mock is its user-friendly UI. Within the UI, users have the ability to modify responses, add response status codes, and perform various other actions. This flexibility allows developers to easily test different scenarios and simulate different API responses without relying on the actual server.

Overall, Oh-my-Mock is a powerful tool for developers who want to efficiently cache and mock API responses. Its intuitive UI and extensive customization options make it a valuable asset for testing and debugging. The extension is available for free on the Chrome platform.
