I spent way too long looking for a self-hosted option so that I could embed a very basic database into my law firm website. I settled on Grist. My goal was to compile a list of tagged links that clients or potential clients would come back to my website to access. You can see the results here: https://www.joshualawfirm.com/links/. I'll note that the db is embedded in an iframe and is slow to load because I am self-hosting on an NAS rather than a dedicated server. If this experiment works, I'd likely migrate the db to a faster server.
