Great service at the sweetest cost. Would you consider offering an API to publish and sync "live" notes from Obsidian to Mataroa?
You'd have to ask the developer; I just use Mataroa. Somehow, though, I get that API would push the boundaries of the minimalist philosophy behind the service.
I just signed up and could see that they do provide an API to enable what you are suggesting. Hope this helps.
Ive been using it for about 2 years and I am satisfied. Cheap, easy to use and minimalistic.
