When you'd choose Login VSI
Login VSI defined the category.
No straw-man comparisons. Login VSI carries real category-defining expertise — these are the strengths a fair-minded buyer should know.
VDI-testing pioneer
Login VSI defined VDI load testing as a category. Real institutional knowledge of Citrix and RDS testing patterns.
Pre-packaged workloads
Library of ready-to-run VDI workloads — Office, Knowledge Worker, Power User. Useful when you don’t want to author your own.
Long enterprise install base
Sat in many enterprise VDI assessments for years; the workloads, references, and integration patterns are familiar.

Compare
Lay LoadGen against Login VSI on custom workloads, web/API testing, DEM, uptime monitoring, and pricing transparency.
Decide
Pick the workload Login VSI doesn’t reach — typically web, API, or DEM — and run the PoC alongside the existing VDI tests.
