Ask HN: Good Tools to Make Landing Pages?

I find that a lot of startups (esp B2B ones) have very similar landing pages.

You know, the one with the call to action, alternating graphic-image columns of use cases, banner of companies that use their product, and the same little icon on the bottom right to chat with someone quickly.

I know there are general web-builder tools such as Squarespace or Unbounce, and I'm sure it's straightforward to code a static site, but curious if anyone knows a popular tool or web framework that is commonly used?
