Yes we use it for rama [1]. You can check its justfile and CI workflow file how we use it. Those run thousands and thousands of tests thx to nextest and what feels like instantly (once compiled).

Large projects build with rama use it as well. But those are proprietary from partners so sadly cannot share those.

Yes, for a long while – I believe it's fairly widely used (and it's absolutely excellent!)

Yep. Tokio uses it for their tests in CI as well last I checked.

Been using it for years, for opensource stuff and at work. No issues whatsoever.

Yes, been using it for 18’ish months. Works great.

Happy user here !
