What is WebLOAD?
WebLOAD is one of the longest-running enterprise load and performance testing tools, maintained by RadView Software. It scripts tests in a JavaScript-based scenario language with protocol-level recording, supports a wide range of legacy and modern protocols (HTTP/S, WebSockets, MQTT, AMF and more), and exposes a rich analytics console for drilling into latency, throughput and resource breakdowns.
WebLOAD is positioned for large enterprises with experienced performance engineers running scripted protocol tests — classic "record, parameterise, replay" workflows against complex back-ends. It can run on-premises or in the cloud and is widely deployed in finance, telecom and government environments where scripted protocol coverage and a controllable test infrastructure matter more than fast iteration.
When WebLOAD is the right tool
WebLOAD is a fair fit when your testing needs look like this:
- Deep protocol scripting. Beyond HTTP — MQTT, AMF, custom binary protocols where a recorder and protocol library save weeks.
- On-premise execution. Air-gapped environments or strict data-residency rules that block cloud-only tools.
- Existing WebLOAD scripts. Years of recorded scenarios already paying for themselves.
If you have a dedicated performance team comfortable with WebLOAD's scripting model and infrastructure, it can deliver under those constraints.
Where WebLOAD stops being enough
WebLOAD's strengths are also where modern teams hit friction:
- Heavy desktop tooling. Script authoring still leans on a Windows-style IDE; cloud-native or developer-led teams expect script-as-code from the terminal.
- Slow iteration. Record-parameterise-replay cycles do not fit short feedback loops in modern CI/CD.
- No bundled CWV or API monitoring. Page speed and API uptime are separate purchases or separate tools entirely.
- License-led pricing. Enterprise license + maintenance is opaque next to per-test cloud pricing.
LoadFocus vs WebLOAD — feature comparison
How LoadFocus compares against a typical WebLOAD enterprise deployment. Pricing accurate as of May 2026.
| Feature | LoadFocus | WebLOAD |
|---|---|---|
| Cost | Free tier; from $29/mo | Enterprise license, quote-based |
| JMeter cloud execution | Yes (up to 12,500 VUs) | Native scripting, not JMeter |
| Browser-based load testing | Yes (Selenium/Playwright) | Limited |
| API monitoring | Yes | Add-on / separate |
| Core Web Vitals monitoring | Yes | No |
| Script-as-code workflow | Yes (JMX / JS) | JavaScript scenarios via IDE |
| Cloud-native execution | Yes (no install) | Cloud + on-prem |
| Pay-per-test pricing | Yes | Enterprise license |
| CI/CD integration | Yes (API + GitHub Action) | API available |
FAQ
Is LoadFocus a direct replacement for WebLOAD?
For most modern HTTP/API load testing scenarios, yes. Teams that depend on WebLOAD specifically for non-HTTP protocols (MQTT, AMF, custom binary) will still need protocol-specific tools; LoadFocus targets the 90% case where teams run HTTP and browser load tests against web apps and APIs.
Can we reuse our existing WebLOAD scripts?
WebLOAD's JavaScript scenarios do not port directly. Most teams migrating choose to re-record the critical user flows in JMeter or a browser tool — usually a few days of work for the top 10-20 scenarios and a faster ongoing iteration loop afterward.
Does LoadFocus support on-premise execution?
No — LoadFocus is cloud-native. If air-gapped or on-prem execution is a hard requirement, WebLOAD remains relevant. Most non-regulated teams find cloud execution faster to set up and cheaper to scale.
What about pricing predictability?
LoadFocus uses transparent monthly tiers starting at $29/month with concurrent VUs and test minutes published upfront. WebLOAD typically requires sales engagement for a quote, and total cost includes license + maintenance + on-prem infrastructure.
How long does setup take?
Minutes for an HTTP test, hours for a full browser scenario. Upload a JMX, paste a URL, or record a flow in the browser — tests run from the cloud immediately, no agents to install.
What about CI/CD integration?
LoadFocus exposes a REST API and a GitHub Action so load tests run on every merge with thresholds for response time, error rate and concurrency. WebLOAD has an API but integration patterns tend to be heavier and team-specific.
