osTicket
osTicket is an open-source support ticketing system with email, web form and API intake, ticket filters, help topics, SLAs and a customer portal. Hosted plans are sold through SupportSystem.
What is osTicket?
osTicket is an open-source support ticketing system. It creates tickets from email, web forms and API calls, routes them to departments with ticket filters, and lets you define help topics. A dashboard reports help desk statistics, SLAs follow your business hours, and a customer support portal lets customers follow their tickets. You download and install the software yourself, or use a hosted version.
Who is it for?
Teams with a system administrator who can install and maintain a self-hosted application and want a free help desk with no per-agent fee. Teams that want chat, social channels or a modern agent interface should compare commercial help desks. Teams without technical staff can use the hosted SupportSystem plans.
Pricing
The software is free. Hosted osTicket is sold by SupportSystem, with a 30-day free trial and no credit card. Prices are per agent per month, and the page does not state the billing period.
- Self-hosted: free, open source.
- SupportSystem Basic: $12, multi-tenant hosting, 2 MB attachment limit, 3 custom domains, unlimited tickets and users.
- SupportSystem Standard: $16, 8 MB attachment limit.
- SupportSystem Premium: $24, 16 MB attachment limit. Marked most popular.
Prices checked on 6 October 2026.
Strengths
- Free and open source: no per-agent license fee when you host it.
- Three intake routes: email, web forms and API create tickets.
- Ticket filters and help topics: route tickets to the right department and define topics.
- SLAs by business hours: set hours once and the system applies them.
- Plugins: the download page offers add-on plugins.
What to consider
- Self-hosting means you run the server, updates and security patches.
- The site lists no live chat, social channels or AI features.
- Hosted plans differ by attachment size: 2 MB, 8 MB and 16 MB.
- Hosted pricing is by agent and the page does not state the billing period.
- The osTicket website is sparse, and the pricing path on osticket.com returns a 404 page. Hosted prices come from the SupportSystem site.
Bottom line
Shortlist osTicket if you have admin skills and want a free ticketing system for email-driven support. Before buying a hosted plan, check the attachment limit and the billing period on SupportSystem.
