What osTicket is

osTicket is an open-source support ticketing system that handles inquiries arriving through email, web forms and API. Ticket filters can create tickets automatically and route them to departments or agents, with options to reject, assign or send canned responses. Teams can tailor custom fields, forms and lists to different help topics. Agents may create tasks independently or attach them to tickets; a ticket cannot be closed while an associated task remains incomplete. The documented API exchanges XML or JSON over HTTP and currently supports ticket creation only. The platform-independent web application integrates with email and can be self-hosted. Its installation documentation lists Apache, LiteSpeed or IIS, PHP 8.2–8.4, and MySQL 5.5 or later as server requirements. Administrators can require multifactor authentication for agents, though this is not required by default. The free download is listed as free with email integration and community support. Cloud hosting starts at $12 a month and includes a 30-day trial; training and commercial support options are also listed.
