Ask HN: Scrappy way to create landing pages?

Anyone have any suggestions on quick/scrappy ways to create/host landing pages for MVPs?

React + Firebase? No-code editors? Quick index.html + script.js?

Criteria: - Easy/quick. Will likely get tossed out. - Needs to be viewable on desktop + mobile (doesn't need to be perfectly responsive). - Don't need any interactivity. - UI/design should look presentable enough to get someone to pay for it.
