Ask HN: Have any OSS projects asked users to donate to build new features?

Hey guys.

I'm considering asking my users to donate to support development of some features.

We're applying for grants to continue development full time but it will be 60-120 days until these really hit.

We're not like Kubernetes or Java where we BigCo funding us in the background.

There are a ton of projects like this but from what I've mostly seen they've done a large Kickstarter and then just started charging for hosting or some other features.

What I'm thinking about is putting up a page saying "Want feature X? We first need to raise $750 ..." or something along those lines.

Thoughts?
