Oops thanks for the heads up! We used to deploy with Surge but we've switched to Nostr-native hosting now with NostrDeploy.com. I'll update the website!
But to answer your actual question, Surge is a static hosting service. Super easy and free, although its closed-source. They recently when down for like a week straight, though, which is why we switched:
Surge
Shipping web projects should be fast, easy, and low risk. Surge is static web publishing for Front-End Developers, right from the CLI.
