Harper – an open-source alternative to Grammarly

Surprised coming into this that I don't see anyone mentioning vale[0]. I've been using it for ~4 years now and love it.

I use grammarly briefly when it came out and liked the idea. Admittedly it has more polish than vale for people writing in google docs, &c. Still, I stick with Vale. Is there any case for moving to Harper?

Looks interesting for linting and cleaning markdown documentation, but it doesn't seem like a very competent "spellcheck". I'll check it out... but it doesn't actually do the same thing as Grammarly or Harper.

Vale requires a lot of tweaking, and I’ve never been able to get a rule set with which I’m happy.

It’s missing a default rule set with rules that are generally okay without being too opinionated.
