Looks promising but looks like cloudflare backed, in documentation they showing cloudflare and other cloud providers deployment ways. If I would create something on hidden service or i2p, i probably would host myself, i mean managing on linux server with Nginx. I assume you can do it with pm2 but still not like strong way to manage. In the other hand, I didn't find any template engine like pug on node.js, maybe I couldn't find it. Thanks for writing it tho, learned a new tech on JS ecosystem :)
