Contao

Contao is a free, open-source CMS for professional websites and scalable web applications. It suits organizations that need self-hosted control over publishing, permissions, multiple sites, or multiple languages. Choose it when your team can manage a PHP/MySQL server or work with a Contao partner; look elsewhere for a fully hosted service.

Overview

One installation can run several websites and multilingual content, which makes Contao practical for organizations managing related brands, regions, or language editions. The core distribution includes calendar, news and blog, and newsletter modules, so common publishing functions do not depend on separate add-ons.

Contao is intended for landing pages, portals, e-commerce, and enterprise sites. It is self-hosted rather than a turnkey hosted platform: deployment uses Contao Manager and its Managed Edition, or Composer to add Contao as a Symfony bundle. That flexibility helps technical teams shape the stack, but it also makes server administration part of ownership.

Key features

• Editorial workflows and permissions: Workflow support, custom user roles, bulk record editing, and restoration of earlier versions give publishing teams control over revisions. Rights can be assigned to individual backend form fields and to users or groups, allowing precise separation of duties instead of only broad administrator/editor access.
• Content and media: TinyMCE supports day-to-day editing, while custom content types and a media library accommodate structured pages and reusable assets.
• Forms and search: A built-in form generator covers data collection. Full-text search supports phrases, wildcards, and AND/OR queries, useful for content-heavy sites where visitors need more than simple keyword matching.
• Accessibility and SEO: Contao describes support for WCAG 2.1 level AA. SEO tooling includes schema.org structured data and automatically generated XML sitemaps, reducing the amount of foundational optimization developers must build themselves.
• Security and privacy: Passkeys or two-factor authentication add stronger login protection, and accounts lock after too many failed attempts. Double opt-in is used for subscriptions and registrations, with logs retained for the legally required storage period.
• Extensibility: Because it is based on Symfony, teams can extend the CMS with packages from the Contao extension directory or Packagist. This is a strong route for custom applications, provided the team can evaluate and maintain extensions.
• Support lifecycle: Community forum support is free, while Contao partners provide professional help. Long-term-support versions receive four years of support, a useful planning horizon for organizations that avoid frequent platform changes.

Pricing

Contao CMS — free: The open-source software is LGPL-3.0 licensed and free for commercial use. There is no paid tier or free trial to compare, so the licensing cost is straightforward. Your practical costs are hosting, deployment, maintenance, and any professional partner support required for a self-hosted installation. The free plan does not remove the need to meet the platform's server requirements or operate the site.

Platforms

Contao runs as a self-hosted web application on Linux-capable hosting and exposes an API. Documentation calls for a web server with current PHP and MySQL, recommending PHP 8.4 or later and MySQL 8.0 or equivalent MariaDB. Confirm that your host meets those versions before committing; platform compatibility is a deployment prerequisite, not an optional upgrade.

Who it's for

Contao is a good fit for professional web teams, agencies, and organizations running portals, multilingual sites, e-commerce projects, or several websites from one installation. It is especially compelling when field-level permissions, structured editorial workflows, built-in search, and Symfony extensibility matter. Teams without server expertise should budget for a Contao partner or choose a hosted CMS instead.

Pros and cons

Pros

• One installation handles multiple websites and languages, reducing duplication for distributed organizations.
• Field-level access rights, workflows, version restoration, and bulk editing support accountable editorial operations.
• Calendar, news/blog, newsletter, forms, and full-text search are included in the core distribution.
• WCAG 2.1 AA support, structured data, XML sitemaps, passkeys or two-factor authentication, and login lockouts cover important governance needs.
• LGPL-3.0 licensing permits free commercial use, with a four-year support period for long-term-support versions.

Cons

• Self-hosting requires current PHP and MySQL infrastructure and ongoing technical maintenance.
• Extension-based customization and Symfony packaging reward developers but can add operational complexity for small teams.
• Professional support comes through partners rather than a bundled paid service, so assistance may need separate budgeting.

Alternatives

Drupal is the closest choice when you want another free, self-hosted CMS with API, Linux, macOS, Windows, and web support, plus a free trial option.

Pick Webflow CMS instead when a hosted web workflow is more important than self-hosting; its free Starter plan is designed for experimenting and limits CMS content, static pages, bandwidth, and form submissions.

Plone suits teams seeking a free, forever open-source CMS across common desktop and self-hosted platforms.

Choose HubSpot Content Hub when a hosted product and small-team entry plan matter; its free tier supports up to two users, with a paid Starter tier from $7.00 per month.

Joomla is another free, GPL-licensed CMS download for self-hosted sites.

TYPO3 CMS offers a free self-hosted edition and a TYPO3 v12 ELTS plan at €3,200 a year for organizations seeking a paid extended-support option.

django CMS is a free, open-source alternative for teams comfortable with a developer-oriented stack.

Umbraco CMS is worth considering when web-based authoring, media management, user management, multilingual setup, and headless APIs are priorities.

Verdict

Choose Contao for a self-hosted professional site that needs multilingual or multi-site publishing, granular permissions, built-in publishing modules, and Symfony-based extensibility without licensing fees. Look elsewhere if you want hosting, infrastructure, and support bundled into a managed service or if your team cannot maintain the required PHP and MySQL environment.
