TL;DR
osTicket has been around since 2003, and it's the go-to open-source ticket system for teams that want full control over their help desk without paying a license fee. The self-hosted version is genuinely free, and the codebase is clean enough that a PHP developer can customize it.
What is osTicket?
Why osTicket Endures
osTicket has survived 20+ years in a market dominated by venture-backed SaaS companies. That longevity says something. The project maintains over 5 million downloads, and the community contributes plugins, translations, and bug fixes regularly. It's not flashy, but it works.
Core Ticket Management
Tickets come in through email, web forms, API, or phone (manually created). The custom forms system is surprisingly flexible — you can build intake forms with dropdowns, checkboxes, date pickers, and conditional fields. Auto-routing assigns tickets to departments or agents based on form data, topic, or source. Collision detection prevents two agents from responding to the same ticket simultaneously.
SLA and Escalation
SLA plans define response and resolution deadlines by priority level. When an SLA breaches, tickets escalate automatically to a manager or backup team. It's not as granular as Zendesk or Freshdesk, but it covers what most teams actually need. Grace periods and business-hour schedules keep SLA calculations honest.
Knowledge Base and Canned Responses
The FAQ module serves as a basic knowledge base. Categories and topics organize articles, and customers can browse them before submitting tickets. Canned responses let agents insert pre-written answers with a couple of clicks. Neither feature will win design awards, but they function reliably.
Self-Hosted vs. Cloud
The self-hosted version requires a LAMP stack (Linux, Apache, MySQL, PHP). Installation takes 20-30 minutes if you've done it before. You get complete data ownership and zero recurring costs. The cloud-hosted version at $12/agent/month handles infrastructure for you and includes automatic updates, backups, and SSL. Both versions share the same core features.
