OpenFIX is the industry's only free, open and fully interactive FIX testing service. Powered by TransactTools' ttCERT technology, OpenFIX is an ideal way for you to test your FIX implementation--both at the session and application layers. OpenFIX is available 24 hours per day, 7 days per week and provides detailed log information for system troubleshooting both during and after testing.

In addition to providing many standard transaction testing scenarios, OpenFIX also provides FPL-certified tests for session-level and 4.4 fixed income scenarios. TransactTools was the first of the FPL-selected "certifier" vendors to launch a public facility for compliance testing.
