Among all the website builders I have managed to test (and I've tried almost all of them), PlatformaLP turned out to be the best option for me. The editor is very convenient and functional, offering a multitude of settings, and it also has a library of ready-made templates on various themes. Integration with analytics services, mailing systems, payment processing systems, and CRMs, as well as advertising pixels, is seamless. There is an option to process requests directly from the service interface — although it doesn't replace a full-fledged CRM, it is quite suitable for small projects with a limited number of requests.
