// EDITOR'S TAKE
Hoppscotch is the nearest equivalent, covering collections, scripted tests and shared workspaces straight from the browser, while Bruno takes the opposite line and stores every request as a plain file in your Git repo, which is better for code review and worse for non-technical teammates. None of them replicate Testfully's hosted scheduled monitoring, so if mock endpoints are the real need, Mockoon does that single job better than any of the general clients.
