LoadRunner · /// Alternative
LoadRunner has heritage. LoadGen has the modern stack.
LoadRunner earned its enterprise reputation — but the cockpit is legacy and the scripting model is VuGen. LoadGen ships a wizard-driven, browser-native cockpit with Citrix HDX + AVD ARM-native depth, plus the monitoring and API testing LoadRunner doesn’t. Transparent pricing, one platform.

The Fair Version
LoadRunner is a real platform.
No straw-man comparisons. LoadRunner has decades of enterprise installs and a deep scripting ecosystem — these are the strengths a fair-minded buyer should know.
Enterprise scripting heritage
VuGen, Truclient, and the LoadRunner protocol library cover scenarios that very few load tools can match — earned through years of investment.
Large installed base
LoadRunner sits in many enterprise stacks already; teams have skills, scripts, and CI integrations built up over a long time. That history has value.
Vendor-backed support
OpenText (the current LoadRunner owner) is a large vendor with formal enterprise-support agreements that many procurement teams prefer.
Why teams move to LoadGen
Three buying-decision walls LoadRunner leaves open.
Teams replacing LoadRunner usually cite the same three friction points: legacy UI, opaque pricing, and the gap where modern EUC platforms (Citrix HDX, AVD ARM, Horizon) need native handling — not generic protocol replay.
Modern, wizard-driven authoring
A 7-step wizard captures Citrix and AVD scenarios in minutes — Subscription / Resource Group / Host Pool for AVD; StoreFront / Gateway / PNAgent / External Login for Citrix. No VuGen, no brittle hand-scripts.
Citrix HDX + AVD ARM native
LoadGen ships native protocol depth — HDX channel pressure, ICA round-trip, FSLogix profile-load, AAD auth, AVD-specific p95 — captured natively, not synthesised from generic HTTP samplers.
Transparent, published pricing
€1,099 / week for Load Testing at the 50-vUser tier, scaling to 25,000 vUsers. €899 / Agent / month for End-to-End Monitoring. No contact-sales wall to learn whether the tool fits the budget.
Modern cockpit
Real-time, browser-native — not a thick client.
The cockpit ops teams actually want to operate during a run. KPI freshness, sessions table, time-range scrub, multi-test overlay — all live in the browser, no installer, no remote-desktop hop into the LoadRunner controller.
- Per-step latency, p95 by protocol (HDX, ICA, AVD), error hotspots — visible during the run, not in a post-test report.
- Up to 5 runs overlaid on one chart — drill into Moments, Errors, and per-step deltas.
- The same cockpit is the live monitoring view after cutover — one engine, two operational modes.
- No VuGen client required to read results — the LoadGen UI is browser-native.
Live cockpit — per-step latency · p95 · multi-test overlay.
No-code API flows
API testing where LoadRunner needs Truclient.
LoadGen ships a visual flow editor with 28 node types and OpenAPI import. End-to-end API journey validation lives inside the same platform as your load tests — no separate Truclient project, no separate license.
- 28 node types: HTTP, REST, SQL, branching, loops, assertions, custom code, OpenAPI import.
- Drag-drop flows author in minutes — replayable as load tests AND as continuous synthetic checks.
- Captured once, runs as both load and monitoring — no re-authoring across modes.
- Same Analytics + AI surface; alerts route to Email / Webhook / SMS / WhatsApp.

How teams move
Three patterns for replacing LoadRunner.
Modernise Citrix / AVD testing
Keep LoadRunner for the legacy protocols that still need it; move the Citrix HDX and AVD ARM scenarios to LoadGen, where the wizards capture them natively.
See use caseConsolidate to one platform
Replace LoadRunner + the separate monitoring + the separate API tool with LoadGen — Load Testing + End-to-End Monitoring + API Testing + SessionSight DEM in one vendor.
See use caseBlock releases on regression
Wire LoadGen into the deploy pipeline. Block deploys on HDX p95 drift, AVD login-latency regression, or API-flow error rate — instead of running a heavy LoadRunner cycle off-hours.
See use caseSee LoadGen alongside LoadRunner on your own stack.
We’ll author a Citrix or AVD scenario in the wizard on a call, fire it from a managed agent, and walk you through the live cockpit — no Truclient project, no controller install.
Questions
Frequently asked.
Does LoadGen replace LoadRunner, or run alongside it?
Both are common patterns. Many teams initially add LoadGen for Citrix HDX and AVD ARM scenarios where the wizards win on authoring speed, and keep LoadRunner for the legacy protocols still in their portfolio. Others consolidate at the next LoadRunner renewal.
What about our existing LoadRunner scripts (Truclient / VuGen)?
LoadGen does not ingest VuGen / Truclient scripts directly — the authoring model is wizard-driven, not script-replay. In practice, teams re-author the Citrix and AVD scenarios in the LoadGen wizard (which is faster than the original VuGen capture) and retain LoadRunner for any niche protocols still required.
How does LoadGen compare on enterprise-scale load (10K+ vUsers)?
The published Load Testing tier scales 50–25,000 vUsers; terms run from 1 week to 5 years. Full and VDI agents land per-session on real Citrix / AVD session hosts; Core agents handle HTTP-only workloads. Scenario shape is the same regardless of scale.
What does it cost compared to LoadRunner?
LoadRunner does not publish pricing. LoadGen publishes €1,099 per week at the 50-vUser Load Testing tier and €899 per Agent per month for End-to-End Monitoring (annual subs include two months free). See the pricing page for tier details.
Can LoadGen replace LoadRunner Cloud or LoadRunner Enterprise?
For the Citrix / AVD / Horizon / RDS / Web workloads LoadGen ships native depth for, yes. For protocols that only exist in the LoadRunner library, you would either re-author in the LoadGen wizard or retain LoadRunner for that specific surface. We’ll walk through your protocol list on a call.
What’s the migration path from LoadRunner scripts?
Re-author the highest-frequency scenarios in the LoadGen wizard first — typically the Citrix HDX, AVD, and API flows. Capture the protocol and auth flow once; replay across load and monitoring modes. LoadGen Services (consulting + managed runs) is available where in-house bandwidth is tight.
