LoadGen vs Login VSI - more capabilities, transparent pricing.
Login VSI pioneered VDI load testing but lacks modern web testing, API testing, and transparent pricing. LoadGen adds SessionSight DEM, uptime monitoring, and custom workloads - all with published pricing.

LoadGen adds custom .lgs workloads, web testing, API testing, and DEM - under transparent pricing.
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.
How LoadGen widens the gap
Audit · Compare · Decide · Adopt.
The four motions every team that switched from Login VSI ran first.
Audit
Catalogue what Login VSI actually runs - pre-packaged workload templates, generic interface, contract-priced licences.
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.
Adopt
Import existing workloads or build new ones with the scenario editor. Keep your existing agents - LoadGen supports Core, Full, and VDI types natively.
LoadGen is broader than VDI load testing
More than a VDI load tool - a unified enterprise platform.
Login VSI pioneered VDI load testing. LoadGen keeps VDI specialization at the core (Citrix, AVD, Horizon, RDS) and adds web, API, uptime, end-to-end monitoring, SessionSight DEM, signed evidence, and enterprise RBAC on the same engine - the breadth EUC operations teams actually need to defend production.
Pricing flexibility
Transparent published pricing - weekly to multi-year terms. No enterprise-only negotiation gate to evaluate the platform.
Massive scale
Scales from 50 vUsers to 25,000 vUsers on the same engine. Real concurrency on Citrix, AVD, Horizon, RDS, and web - not synthetic ceilings.
Uptime Monitoring
HTTP, REST, SQL, and Azure availability checks included alongside load and end-to-end monitoring. One platform, one audit trail.
API Testing
Visual flow editor with 28 node types, OpenAPI / Swagger import, reusable auth profiles - no scripting required for service validation.
Enterprise governance
Multiple built-in roles plus custom roles, HTTP-method-level RBAC, identity-provider SSO (AD / Entra ID / Okta) - the guardrails enterprise teams need.
Signed evidence + audit
Every test, grant, rotation, and export writes into an immutable, signed audit chain. SLA validation and compliance reviews on one trail.
Unified platform
Load + End-to-End Monitoring + SessionSight DEM + API Testing + Uptime in one operational surface. No three-vendor seams to debug.
Operational visibility
Live SignalR cockpit + SUT monitoring overlay infrastructure health on user response times. The cause and the symptom on the same timeline.
The point isn't replacing Login VSI on its strongest feature - it's consolidating onto one platform where every adjacent capability is already there.

Heatmaps, session replay, journey analysis, and visitor tracking Login VSI doesn't offer.
Uptime Monitoring
HTTP, REST, SQL, and Azure checks with incidents and maintenance windows.
Transparent Pricing
€ 1,099/week for 50 vUsers. No "contact sales" for basic pricing.
Custom Workloads
Upload .lgs scripts with Minor / Major / Patch versioning. Not limited to templates.
125 Routes
Comprehensive web UI vs Login VSI's limited interface. Total platform control.
Migration play
