Alternatives

Before building my own app, I looked around at similar apps. However, none was completely satisfactory so I rolled my own. Also the almost-good-enough apps are not open-source.

Alternative	Differences
HyperSwitch and HyperDock	Closed-source. Thumbnails are too small. App icon is on top of the thumbnail
Witch and Context	10-15$. Closed-source. Focus on text. No thumbnails
Built-in MissionControl	No keyboard support
`⌘ command` + `⇥ tab`	Only shows apps, not windows (note: can press down to see window of selected app)
`⌘ command` + `	Cycles through tabs and windows, but only of the same app. Only cycling, no direct access
