I thought it supports most file storage sync solutions? I’m using with the free iCloud level storage I believe.
I’m responding more to the comment that it’s extra steps. It’s clearly not as good a solution as obsidian, but there are no extra steps for it being accessible over the web or to all your devices - not just those for the devices built in cloud provider.
I think GitHub/gitlab issues is totally viable. Obsidian/Logseq too.
Or just use GitHub/gitlab issues.
