What OpenSupports is

OpenSupports is a free, open-source ticket system for managing customer support inquiries. Customers can create accounts to keep tickets together or submit requests through a form without an account. Staff organize tickets by department and use filtering and search tools to locate conversations. Teams can publish FAQ and how-to articles as a knowledge base, while administrators assign staff departments, roles, and permissions. Ticket comments support file attachments, configurable maximum file sizes, and reCAPTCHA. A REST API connects OpenSupports with other applications, and settings include SMTP and IMAP configuration. The listed interface languages include English, Spanish, German, French, Portuguese, Italian, Greek, Japanese, Russian, Chinese, Hindi, Turkish, Polish, and Dutch. The self-hosted plan costs nothing and requires PHP 7.x or later, MySQL 4.1 or later, and a PDO driver. Installation documentation lists Apache 2.4+; PHP 8 is not supported yet.

Who it suits

OpenSupports suits support teams wanting a self-hosted help desk with customer accounts, knowledge-base articles, and role controls. Managed hosting is described for businesses that prefer not to handle installation and maintenance.
