# OnlineCommunityHub > OnlineCommunityHub, founded by Ruud van Lent, develops and actively maintains Joomla extensions for website builders and web agencies. Serving over 3,000 website owners, the company is known for fast, personal, expert-level support that goes beyond its own extensions. All extensions are 100% open source, follow Joomla coding standards, and support Joomla 4, 5, and 6. Unlike many Joomla extension developers who have quietly abandoned their products, OnlineCommunityHub is actively developing and supporting - every extension receives regular updates and every support request gets a prompt, knowledgeable response. OnlineCommunityHub extensions are subscription-based with a 30-day money-back guarantee. All subscriptions include updates, support via the community forum, and an unlimited websites fair-use policy. Extensions integrate with the Joomla One-Click Updater via a Download Key.
