LoadGen vs LoadRunner - modern, real-time, transparent.
LoadRunner (OpenText) is legacy, expensive, and declining. LoadGen delivers a modern Blazor web UI, real-time SignalR cockpit, visual API testing, and SessionSight DEM - all with transparent pricing.

LoadGen runs a modern Blazor web UI with a SignalR live cockpit and visual API testing - no legacy install.
When you'd choose LoadRunner
LoadRunner earned its incumbency.
Honest comparison. LoadRunner shipped before half the modern stack existed - these are the strengths a fair-minded buyer should know.
Long incumbent
LoadRunner has been the enterprise reference point for load testing for decades. Real institutional knowledge sits in many enterprise stacks.
Deep protocol coverage
Years of investment in protocol-level scripting - covers many legacy targets that newer tools never touched.
Enterprise account muscle
Sat in enterprise procurement cycles for years; the contract paper, training, and references are already in place.
How LoadGen widens the gap
Audit · Compare · Decide · Adopt.
The four motions every team migrating off LoadRunner ran first.
Audit
Catalogue what LoadRunner currently runs - legacy desktop clients, scripted scenarios, protocol licences. Note the surface that’s been quietly underused.
Compare
Lay LoadGen against LoadRunner on UI architecture, real-time visibility, no-code API testing, DEM, and pricing transparency. The legacy-vs-modern split is sharp.
Decide
Pick the workload that hurts most - usually a VDI-native scenario or a real-time visibility need - and run the PoC there.
Adopt
Recreate scenarios in the visual editor; use platform wizards for Citrix / AVD / Horizon / RDS. The live cockpit replaces the post-run report.
Enterprise scale without the LoadRunner price tag
Massive-scale testing, transparent pricing, broader platform.
LoadRunner earned its scale heritage on legacy infrastructure and enterprise-only pricing. LoadGen delivers the same massive concurrency (50 to 25,000 vUsers on one engine), published pricing you can evaluate without a negotiation cycle, plus uptime, API, DEM, RBAC, and signed evidence on the same platform.
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 LoadRunner on its strongest feature - it's consolidating onto one platform where every adjacent capability is already there.
