Product Features

There are two versions of our product, light open-source version and more advanced commercial version highly optimized for web and cloud environments including mobile apps and support for many platforms.

Use free open-source version for basic usage or to get free terminal for your development and testing environments. You can extend it as you like, add new features as you like as long as it is free and open sourced. Free version does not have many features commercial version has. From integration with document management software provided by our partners, computer vision, mobile apps, technical support and many more.

Below is a comparison table with available features and their short description. Hover mouse over a feature to reveal more details.

Json WebSocket

Standard text-based protocol that uses about 20x more data for screen transfer than binary mode. It is good enough for small number of clients and local network.

Open Source Tn5250J

Based on open-source project. Commercial version uses inhouse developed highly optimized module based on event-based networking model which does not use Tn5250J.

Thread Based Networking

Networking technique where every concurrent session requires more than one thread which limits number of concurrent sessions and have much higher demands for resources.

Integration with other web pages
