I'd like to mention two platforms that I personally utilize.
The first one is Wix, which is a widely recognized visual website builder designed for creating small websites such as business cards, landing pages, and small online stores.

The second one is Site 123, another simple website builder that performs its intended functions flawlessly without unnecessary features that might confuse users. Both platforms are beginner-friendly and user-friendly.

Among semi-professional developers, the most popular are WordPress, Tilda, Joomla. It is worth noting that it is quite easy to create even a mini store on WordPress, although for this you need to add the (free) WooCommerce application.

Hi! Now there is a very wide variety of such platforms that it is really difficult to choose a reliable and good one. But I've heard a lot about Hostinger. There are good rates, and in general, this platform is very convenient for work.

WIX is a globally popular online website builder available in 20 languages and over 190 countries, with over 180 million users worldwide. It stands out for its unique approach to design, which includes a wide range of pre-made templates created by professional designers and an artificial intelligence-based service for generating designs based on user preferences (Wix ADI).
Additionally, the platform offers a functional online page editor and various related services, including a logo designer and applications from their store to add extra functionality. The platform has free SSL certificates and can be used to build any type of website.

WordPress is an open-source content management system that was initially developed for blogging but is now used for other tasks. The platform is renowned for its convenience, wide recognition, well-documented developer information, and a growing collection of add-ons. On WordPress, users can create everything from single-page landing pages to complex online stores with extensive functionality and integrations. There are numerous resources available on the web, but reliable hosting is required, such as Bluehost.

OpenCart is a free, open source e-commerce platform similar to WordPress. It has a large and active community with a vast range of extensions and themes available on the official catalog, many of which are free. Small and medium-sized businesses are the target audience for OpenCart, but it can be used for larger projects if full-time programmers are available. Despite the potential complexity when using the original official build, the advantages include the flexibility to create custom add-ons and features, and the availability of many forked builds.
