Question 1

What is Mock Dream?

Accepted Answer

Mock Dream is a free Chrome extension that intercepts fetch and XHR requests in any tab and replies with mock JSON, headers and status codes you define visually — no server, no sign-up.

Question 2

How is it different from Mockoon, Beeceptor or Requestly?

Accepted Answer

Mockoon and Beeceptor run a local or cloud mock server. Mock Dream runs entirely inside the Chrome popup with zero servers and zero accounts. It is more focused than Requestly: rules, traffic console, JSON formatter, per-rule CORS and themes — that's it.

Question 3

Does Mock Dream collect any data?

Accepted Answer

No. Zero telemetry, zero tracking, zero accounts. Every rule and request lives in chrome.storage.local on your machine.

Question 4

Can I mock fetch and XMLHttpRequest at the same time?

Accepted Answer

Yes. Mock Dream patches both window.fetch and XMLHttpRequest from a single rule, so the same mock works for axios, native fetch, jQuery.ajax and legacy XHR code.
