Why I built CmdTab

I switch between a lot of windows on my Mac every day, and Cmd+Tab only switches apps. I tried the existing window switchers, but each had problems I couldn’t fix or add to myself. So I built CmdTab, with the features I wanted.

It’s still in private beta and I’m improving it often. I’m sharing it with other Mac users in the hope it solves the same frustrations for them. If something doesn’t work for you, tell me at trycmdtab@gmail.com and I’ll fix it.

Product approach

CmdTab replaces an app-only switching view with individual window entries, real previews, search, quick actions, and multiple presentation modes. The current implementation treats exact windows as one global recent-use sequence instead of forcing windows from one app into a group.
