I've said this before, but happy to write it over and over. One of the co-founders was my old EM at Uber. He's as sharp as they get, and very kind and humble to boot. If you are looking to support companies started by people that are definitively Not Jerks, check this one out.

Is this made by the same people who made https://www.raycast.com/?

The website design seems uncannily similar.

Different teams I believe. I think Raycast team uses Linear for issues and I am sure they inspire each other.

Raycast has Linear as one of the core extensions it lists: https://www.raycast.com/extensions/linear/

Since you've mentioned Linear, I'd add Restya Core. It has many interesting features. (Disclosure: I was on their private beta)

Great collection! Thanks for sharing
