osTicket is a widely-used open source support ticket system. It seamlessly integrates inquiries created via email, phone and web-based forms into a simple easy-to-use multi-user web interface. Manage, organize and archive all your support requests and responses in one place while providing your customers with accountability and responsiveness they deserve.

How osTicket works for you

  1. Users create tickets via your website, email, or phone
  2. Incoming tickets are saved and assigned to agents
  3. Agents help your users resolve their issues

osTicket is an attractive alternative to higher-cost and complex customer support systems; simple, lightweight, reliable, open source, web-based and easy to setup and use. The best part is, it's completely free.

osTicket now supports bleeding-edge installations. The easiest way to install the software and track updates is to clone the public repository. Create a folder on you web server (using whatever method makes sense for you) and cd into it. Then clone the repository (the folder must be empty!):

git clone

And deploy the code into somewhere in your server's www root folder, for instance

cd osTicket
php manage.php deploy --setup /var/www/htdocs/osticket/

Then you can configure your server if necessary to serve that folder, and visit the page and install osTicket as usual. Go ahead and even delete setup/ folder out of the deployment location when you’re finished. Then, later, you can fetch updates and deploy them (from the folder where you cloned the git repo into)

git pull
php manage.php deploy -v /var/www/htdocs/osticket/


osTicket supports upgrading from 1.6-rc1 and later versions. As with any upgrade, strongly consider a backup of your attachment files, database, and osTicket codebase before embarking on an upgrade. Please review our Upgrade Guide or the UPGRADING.txt file for upgrade instructions.


Visit the Documentation or the forum. And if you'd like professional help managing your osTicket installation, commercial support is available.


Create your own fork of the project and use git-flow to create a new feature. Once the feature is published in your fork, send a pull request to begin the conversation of integrating your new feature into osTicket.
