This question itself is too provocative to ask, but users are always wondering – why should I use this platform and not WordPress (Joomla!, etc.)?
TYPO3 CMS is a good platform for a medium or large project, a site for which flexibility and extensibility are important. Of course, the flexibility of the engine means that it must be handled by a competent person who can understand the customization system and understand how TypoScript works.
If you are a customer (or just thinking about what to create a website on), TYPO3 CMS will suit you if:
you have a medium or large budget for creating a website;
your site is not an online store or a social network;
the number of pages will be approximately average (not small – 10-20, but not large – 5-6 thousand);
you will not use the built-in CRM.
This doesn’t mean that you can’t implement the above written on TYPO3; it means that implementation will be problematic, so it’s easier to take some other, more suitable CMS.
To summarize, TYPO3 is a great fit for medium-sized companies.
TYPO3 CMS extensions
Extensions are plugins that can be selected in TER and then installed via TYPO3 CMS using the Extension Manager in the menu. TER is the TYPO3 Extension Repository and it can be found here. This is the official collection of extensions for TYPO3.
As in other CMS, here extensions have the most different functionality: some of them affect only the appearance of pages, others are responsible for internal features; most of them affect the internal and external sides of the site (we are talking about news, galleries, etc.). You will have a large scope for customizing these extensions.
