Looking for a Custom Plugin like VC

I am looking for someone who can suggest me a full page custome plugin like Visual composer but light one.

See this page: https://www.lyncconf.com/games-like-mass-effect/

I am using right now VC trial one and this caused the website to load heavy.

Any suggestions will be appreciated.

Have you tried this one: https://elementor.com/

Heard about this one but never tried.

Let me know one more thing, if we make a page with elementor and later delete the plugin, does it effect that page made with elementor?
