No, I run several small websites on Vercel for free for years, always served static pages very quickly

Static pages, sure. But what do you do if you want a contact form or something? Yeah, you can use services like formspree, but then you may end up paying $20/month for that alone. Perhaps I'm just ignorant.

Render offers free static sites that are served via a CDN and load instantly: https://render.com/docs/static-sites

When I said landing page, I had contact forms and more in mind, not documentation sites.

But that is news to me. Interesting. Although for static sites, I always use Netlify or even GitHub pages.
