Seamless Terminal Emulation with OpenLegacy
Modernize your legacy system interactions with browser-based terminal emulation that's easy to deploy, manage, and use — all without compromising the power of your existing infrastructure.
The Legacy Terminal Challenge
In today's hybrid IT landscape, organizations continue to rely on legacy systems like mainframes and AS/400 to support their core business operations. However, interacting with these systems through outdated terminal interfaces or locally installed emulators can be limiting, inconsistent, and costly to maintain.
Local Installation Burden
Time-consuming setup on each user's machine
Inconsistent Experience
Different versions and configurations across devices
Difficult to Scale
Complex maintenance and updates across the organization
Traditional Approach
Local emulator installations on every machine
