Fusion5250 is the only emulator that runs IBM 5250 terminal programs natively in a browser, directly within the Valence Portal. Any legacy green screen program works in Fusion5250—no additional fat client, skinny client, screen-scraping, source code or recompiling required. Fusion5250 simply works—and works fast—as a standard feature of Valence 5.2+.

How it works.

There are other 5250 emulators on the market, including browser-based options, but none offers the simplicity, flexibility and performance of Fusion5250. We created a decoder that reads the 5250 data stream directly from the IBM i and translates the raw code into JSON format. This allows the Valence user interface to render your legacy programs in the browser, exactly as they would appear on a 5250 terminal. Direct two-way websocket communications with the server ensure exceptional performance, especially compared to screen-scraping green screen emulators.

Why it's the best choice.

Use Fusion5250 to run all your legacy 5250 apps side by side with your modern apps, using a single sign-on and launching all apps from the Valence Portal. Update your legacy apps to modern Valence apps within the same workspace. Give users their choice of any standard browser.

  • Get fast, reliable performance for any 5250 programs—without the unwieldy terminal or slow, glitchy, screen-scraping emulators.

  • Move your legacy 5250 programs directly to Fusion5250 and run them natively—with no special client software, no source code, and no recompiling necessary.

  • Access all your apps—legacy and modern—from the Valence Portal.

  • Set user access, auto login, listener port, prestart jobs and advanced options directly through the Valence Portal admin settings.

  • Create startup macros that go straight to the legacy screen that users need, with no navigation from the main menu required.

  • Keep the traditional green screen look, or let users choose an alternative color theme.

  • Move 5250 users to a browser environment with Valence and Fusion5250 on day one, providing additional modern apps with Nitro App Builder and other Valence tools whenever you’re ready.
