Why Contao?

Versatile

Regardless of whether you want to run multiple websites in one Contao installation, maintain a website in multiple languages or need detailed user permissions to work on a website collaboratively – Contao has everything on board by default. Furthermore, you can enhance its functionality with extensions to fit your needs.

GDPR compliant

Contao is compatible with current laws and especially the GDPR. All data protection measures are implemented by default, for instance, Contao uses the double opt-in method for all subscriptions and registrations and it keeps a log for the legally required storage period.

SEO ready

You can adjust the title, the description and the robots meta tag of each page. Redirects and error pages always send the correct HTTP status code. In addition, Contao uses schema.org to tag content for search engines and it automatically generates an XML sitemap that can be submitted to Google, Bing and other search engines.

Accessible

With Contao, you can create accessible websites that meet the requirements of BITV 2.0 and the European Accessibility Act (EAA). The Contao administration area itself is also largely accessible and compatible with assistive technologies.

Performant

Contao is compatible with Varnish and other HTTP caches and it supports modern technologies such as HTTP2, deferred image resizing and ESI. Even with big installations with hundreds of thousands of pages, Contao remain performant and delivers your website in a flash.

Secure

Contao uses modern password hashing algorithms and supports securing user accounts with passkeys or 2-factor authentication. Moreover, user accounts are locked automatically if there are too many failed login attempts.

Satisfied users

Over 175,000 websites have already been built with Contao, from landing pages to portals to e-commerce and enterprise sites. Users especially appreciate that despite of its many possibilities, Contao is still easy to learn and intuitive to use for editors.
