⚡ Quick answer

osTicket is a widely used support ticket system. It brings inquiries from email, phone and web forms into a multi-user web interface where agents manage, organise and archive requests. It suits small support teams that have a PHP host and want a no-licence help desk.

What it is

Users open tickets through your website, email or phone, the system saves and assigns them to agents, and agents respond. The osticket.com site lists dashboard reports, ticket filters, configurable help topics, a customer support portal and service level agreements. It runs on Apache or IIS with PHP and MySQL.

Who it's for

It suits IT teams and small businesses that can run a PHP and MySQL stack and want a simple, lightweight help desk. It does not give you a managed service by itself: for hosting you either run it yourself or use the separate cloud-hosted SupportSystem product.

Key features

Multi-channel ticket intake

Email, phone and web-form requests all become tickets.

Ticket filters

Filters route tickets to the right department.

Configurable help topics

Add, edit and delete the topics your help desk offers.

Customer support portal

Customers get a portal to follow their requests.

Service level agreements

Set business hours and SLA rules the system applies.

Translatable interface

The interface is translatable, with language packs on the download page.

How to start

Up and running in 3 steps

1
Check the requirements: Apache or IIS, PHP 8.2 to 8.4, mysqli and a MySQL database.
2
Clone the repository and run php manage.php deploy --setup /var/www/htdocs/osticket/ to deploy to your web root.
3
Open the site in a browser, run the installer, then delete the setup folder from the deployment.

Our honest verdict

What's great

  • Email, phone and web-form requests all land in one ticket queue.
  • Runs on a plain PHP and MySQL stack, with Apache or IIS, rather than needing containers.
  • The interface is fully translatable, with language packs offered for download.
  • Commercial support and hosting services are available if you do not want to run it alone.

Where it falls short

  • You must provide an HTTP server, PHP 8.2 to 8.4 and MySQL 5.5 or greater, plus several PHP extensions such as imap, intl and gd.
  • The README describes deployment by cloning the repo and running php manage.php deploy, which needs command-line comfort.
  • You handle your own backups and upgrades; the README advises backing up attachments, database and code before upgrading.
  • Hosted help desk is a separate product (SupportSystem), so the free GPL download means you run and maintain the server yourself.
Cost

Pricing & license

osTicket is free under GPL version 2. osticket.com shows a 30-day free trial of the separate cloud-hosted SupportSystem but no price, so if you self-host the only cost is your server and any commercial support you buy.
