(fallen london stamps by I can't vouch for it myself, having no personal experience with it, but https://micro.blog looks interesting. It's paid, but has a free trial period.
Main highlights are that (despite the name) it works for longposts as well as tiny ones, and it lacks vanity metrics.
Also found while poking around:
- https://mataroa.blog (has a free option)
- https://pika.page (has a very limited free option that's more of a trial than anything)
- https://write.as/ (has a free option, but they've put signups for it on hold. paid tier is still open for signups) (used this one long ago - was good then, but have no recent experience with it)
