I recently used Bunny for a small project. Pretty good experience. And they're rolling out new functionality at a good pace.

Used them in my last project for around 5 years. They were boring in a good way and inexpensive.

Too bad they don’t support mtls client certificates or something that would allow me to limit the connection to just their servers.

I use them too. Highly recommend. Have never had an issue with them.

Hetzner and Bunny are solid choices for EU projects.
