What is Liberator?

Liberator is a very efficient server for real-time information. Using common internet technologies, it effectively bypasses proxies and delivers streams of information to anyone with a browser and a connection to the internet. It is written in a low-level language so performs very efficiently.

Who makes Liberator?

It has been developed by Caplin Systems for several years and is used by many well-known financial institutions. It is relied upon daily for large transactions in real-world trading scenarios.

Why are you giving it away for nothing?

Because we want to make it as easy as possible for people to evaluate, and because we want to increase its popularity by making it free to use in non-commercial applications.

How do I get Liberator Free Edition?

Follow this link.

Is Liberator Free Edition limited in any way?

The Free version is the same software we provide to our paying clients. The major difference is that we do not include our advanced APIs for .NET, C/C++ and Java. Authentication permissioning is also disabled as is enterprise-level JMX monitoring. See the feature comparison for more details.

Why do I have to register to use Liberator?

We would like to know who is using our product for marketing and tracking purposes. We will not release your data to any third parties or send you any email junk. Privacy Policy

Do you offer support?

Since this is not a commercial release, we are not offering support for Liberator Free Edition. There is a forum which is monitored by our team. If you would like to talk to us about our full range of services, including support, please follow this link and leave your details on our website.

What is SL4B?

SL4B stands for StreamLink For Browsers. It is the name for the system we have created enabling real-time data display across browsers.

What is RTTP?

RTTP is the protocol used by Liberator to transmit information to the browser. It works in a similar way to http and is thus able to effectively bypass proxies and firewalls.

What is RTML?

RTML is a simple markup language you can use to create pages containing real time data. It wraps around SL4B, allowing you to access the power of Liberator with minimal investment of time.

What is DataSource?

DataSource is the name for the component which provides data to Liberator.

Can I run Liberator Free Edition on Windows?

Yes! You can run it in a virtual Linux machine using the free VMWare Player. Download a minimal Linux Virtual Appliance such as this one. When you have your virtual machine running, follow the getting started guide for installing on Linux.

Where can I find more information about Comet?

The 'What is Comet?' page gives a brief overview of Comet. If you would like to read more about Comet you can find lots of information at CometDaily and Wikipedia.
