What is LoadStorm?
LoadStorm was a US-based cloud load-testing service founded 2010 by CustomerCentrix, focused on web application load testing for ecommerce, education, and SaaS verticals. Pitch: ramp up real-user simulations from the cloud without managing infrastructure. Where it fell short for many modern teams: prepaid virtual-user packs instead of a subscription, proprietary test scripting (not standard JMeter/k6), no native synthetic API monitoring, no Core Web Vitals depth, and a UI that felt behind modern SaaS competitors.
When LoadStorm was the right pick
- You needed one-off load tests and preferred prepaid virtual-user packs to a monthly subscription.
- You were an ecommerce/education vertical and LoadStorm's industry templates fit.
- You didn't have JMeter/k6 scripts yet and preferred LoadStorm's GUI test builder.
Where LoadStorm leaves gaps
- Proprietary scripting. LoadStorm's test format isn't JMeter or k6, vendor lock-in.
- Prepaid VUser packs. LoadStorm sold packs of virtual users rather than a subscription: Basic $299 (5,000 VUsers, 1-hour max per test), Advanced $699 (15,000, 2 hours), Premium $1,799 (50,000, 4 hours), Premium Plus $3,999 (150,000, 10 hours) and Enterprise $9,999 (500,000, 10 hours). Prices from LoadStorm's last published pricing page (archived May 2025), checked October 2026. Tests were unlimited and VUsers never expired, but each test drew down VUsers by its peak user count, so regular load testing cycles meant buying packs again.
- No native synthetic API monitoring. Load-test-only product.
- No Core Web Vitals depth. No Lighthouse/page-perf coverage.
LoadFocus vs. LoadStorm: comparison
| Feature | LoadFocus | LoadStorm |
|---|---|---|
| JMeter cloud execution | Yes, .jmx unchanged | No (LoadStorm proprietary scripting) |
| k6 cloud execution | Yes, .js scripts | No |
| Synthetic API monitoring | Yes, included | No |
| Core Web Vitals depth | Full Lighthouse | No |
| Pricing model | Flat monthly SaaS | Prepaid VUser packs (no longer sold) |
| Entry price | $29/mo ($19/mo billed yearly) (50 test runs a month on Starter) | $299 for 5,000 VUsers (last published price, May 2025) |
| Test scripting | Industry-standard JMeter/k6 | LoadStorm proprietary GUI |
| Setup time | Minutes (upload .jmx/.js) | Minutes (LoadStorm test builder) |
| Free tier | Forever | Limited trial (no longer offered) |
When LoadFocus is the right pick
- You run regular load testing cycles (weekly/monthly) where per-test or prepaid usage pricing adds up fast.
- You use industry-standard JMeter or k6 scripts instead of proprietary formats.
- You need synthetic monitoring + load testing + Core Web Vitals in one tool, not separate vendors.
- You want flat predictable pricing: no surprise bills per campaign.
- You want a permanent free tier for prototyping or small projects.
Migrating from LoadStorm
- Inventory existing LoadStorm test scenarios by their parameters: URLs hit, user count, ramp profile, duration.
- Rebuild as JMeter (.jmx) or k6 (.js) scripts: manual rebuild from LoadStorm's scenario configuration. No automated converter (proprietary format).
- Upload to LoadFocus: runs on Apache JMeter / k6 without modification.
- Compare results with your last LoadStorm reports to verify p95/p99/error-rate parity.
- Retire the LoadStorm scenarios once the comparison confirms parity.
FAQ: LoadFocus vs LoadStorm
Can I import my LoadStorm scenarios into LoadFocus?
Not via automated converter. LoadStorm's scripting format is proprietary. Manual rebuild as JMeter (.jmx) or k6 (.js) is the migration path. Typically 30-60 minutes per scenario.
Is LoadFocus cheaper than LoadStorm?
LoadStorm can no longer be bought, so the comparison is mostly historical. LoadFocus load testing is $29/mo ($19/mo billed yearly) with 50 test runs a month on Starter. LoadStorm sold prepaid VUser packs, from $299 for 5,000 VUsers up to $9,999 for 500,000; the number of tests was not limited, but each test used up VUsers by its peak user count, so the cost depended on how big and how often you tested.
Does LoadFocus have a GUI test builder like LoadStorm?
LoadFocus's primary interface is upload-and-configure for .jmx/.js scripts. For code-shy users, the JMeter GUI (free, runs locally) is the standard way to build .jmx scripts visually, then upload. k6 scripts are JavaScript code.
What about industry-specific templates (ecommerce/education)?
LoadFocus's `/templates` library has 600+ load-testing scenarios across many industries. Search for your use case + adapt the .jmx/.js template.
Can LoadFocus do API monitoring + load testing together?
Yes, both in one tool. Reuse monitor configurations to generate load tests, or build separately. LoadStorm doesn't do synthetic monitoring.
What about Core Web Vitals?
LoadFocus runs scheduled Lighthouse audits + tracks LCP/CLS/INP over time. LoadStorm has no equivalent.
