The company Login VSI offers software solutions to test and actively monitor the performance and availability of virtual desktop environments (VDI and DaaS/SaaS).

Our customers are enterprises with virtual desktop infrastructures (VDI) and business critical applications running in VDI and Cloud such as AWS and Azure. Login VSI is also extensively used by all IT vendors active in providing infrastructure solutions for VDI.


The first product, load generator Login VSI, was designed and built by experienced VDI consultants that needed an easy-to-use tool for benchmarking, load- and stress-testing, scaling and sizing, and change impact analysis, of virtualized desktop environments such as Microsoft Terminal Server (now Remote Desktop Services), Citrix XenApp, and later Citrix XenDesktop and VMware Horizon View.

What our customers are saying

Jamie Vernon - STARTEK

"Login PI enables us to minimize system downtime and deliver strategic business value like never before."

Jamie Vernon, VP of IT and infrastructure at STARTEK

Keith Hageman - Micron

"When I joined Micron in June 2014, the first thing I did is find out if we have a copy of Login VSI and if we could run a 1000 user test case instance (which we could). We use Login VSI to run tests for customers and for case studies and I really have loved Login VSI for the last 3 or 4 years.”

Keith Hageman, Senior Solutions Architect at Micron Technology

Randy Groves - Teradici

"As the developer of the PCoIP protocol, we do a lot of our own internal benchmarking to make sure that we’re continuing to improve our protocol. But we can’t actually publish our internal benchmarks because everybody might think that the tests are biased. So when we want to publish results, we use Login VSI. That way, if a customer wants to repeat our results they can.”

Randy Groves, CTO at Teradici
