Load Testing Services:
Web, Mobile and APIs

Vervali runs load testing: the traffic you expect, and the peak you have to survive, on web, mobile and APIs, using k6, JMeter and Gatling. Every engagement ends with the breaking point, the bottleneck and what to change, written so a product owner can act on it. Stress past the peak and deep soak work are on their own pages.

Expected Traffic, Peak Load and the Bottleneck Named

Load is the traffic you named, not a round number of virtual users on the home page.

The Traffic You Expect

The journeys and volumes your analytics show, run against staging before a launch or a campaign. We do not invent a concurrent-user number we cannot evidence.

The Peak You Have to Survive

A sale, a campaign or a month end, modelled from your own history rather than a generic spike.

Web

Pages and journeys under concurrent load, with response times and errors at each step, including the checkout, search and login people actually use.

Mobile

The API and backend traffic a mobile client produces. Device coverage is on mobile application testing.

APIs

A screen that stays up while a service times out is a failed journey. The API slice is on API load and performance testing.

The Bottleneck Named

The cause behind a slow run, named in your own units, not a graph with no explanation.

Need the peak before your users find it?

How This Work Is Packed

Load testing is one slice of performance work. These are the neighbouring packs.

Performance Testing

Load, stress, soak and spike, with the bottleneck named in plain English. See performance testing.

Stress Testing

Load pushed past the expected peak to see where the system fails and recovers. See stress testing.

Scalability Testing

Capacity and scale-out, and whether the product grows with demand. See scalability testing.

Performance Optimization

Tuning after the finding. See software performance optimization.

Already know the peak? A QA lead can scope the load test.

Tools, Pipeline and Reports

What we run, where it runs and what you receive.

k6, JMeter and Gatling

The defaults, with cloud load generation when the volume needs it. Named extras are added to the quote when you name them.

In the CI/CD Pipeline

GitHub Actions, Jenkins or Azure DevOps. Pull requests get a short set and nightly gets the wider load. See DevOps consulting and CI/CD.

The Report

The breaking point, the bottleneck, what to change and what was not tested, written so a product owner can act on it.

Proof From Delivery

Three delivery engagements, sector and country. They show Vervali has tested systems at that scale and were not load-testing-only jobs.

India · major airline · booking and check-in

A major airline booking and check-in platform. After: 40% faster page loads. Load on a booking path is concurrency, not a round number of virtual users on the home page.

40% faster page loads

Australia · cybersecurity SaaS · DDoS simulation

A cybersecurity SaaS product under high-intensity DDoS simulation. After: 99.9% platform stability on that run. Load includes how it fails, not only how green the dashboard looks.

99.9% platform stability

India · Mumbai supplements retailer

Peak-load work on a retail storefront. After: 40% faster pages and 50% more mobile conversions. The peak that mattered was concurrency at checkout.

40% faster pages 50% more mobile conversions

How an Engagement Starts

From the peak you fear to a result you can plan around.

  • 01

    Share the Peak

    Tell us the peak you have to survive and the surfaces in play (web, mobile, APIs), with a staging URL under NDA.

  • 02

    Get the Traffic Model

    We build the profile from your analytics: which journeys run, how they are weighted and where concurrency peaks.

  • 03

    Start With a 1-Hour Load Test

    A free 1-hour load test on a staging URL is the first look. Most engagements land at $25 to $49 an hour blended, and price follows the surface and the peak.

  • 04

    Get the Report

    The breaking point, the bottleneck and what to change, 9am to 1pm Eastern with delivery from India.

One staging URL, tested honestly

Frequently Asked Questions

It checks how a system behaves under the traffic you expect, and the peak you have to survive, before a launch or a campaign. k6, JMeter and Gatling are the defaults. Deeper peak load and soak are on performance testing, and a free 1-hour load test is the first look.

Load is the traffic you expect. Stress is past that until it fails. Scalability is whether the product grows with demand and comes back when the spike is over. See stress testing and scalability testing. We do not invent a concurrent-user number we cannot evidence.

APIs are in scope when you name them. A screen that stays up while a service times out is a failed journey. The API slice is on API load and performance testing, and functional coverage is on API testing services.

k6, JMeter and Gatling are the defaults, with cloud load generation when the volume needs it. Named extras are added to the quote when you name them. The traffic model matters more than the tool, and a free 1-hour load test shows which of these you already have.

Yes, when that is in the quote: GitHub Actions, Jenkins or Azure DevOps, whichever you already use. Pull requests get a short set and nightly gets the wider load. Pipeline design is on DevOps consulting and CI/CD. A free 1-hour load test shows what already runs.

It follows the surface, whether the peak is already named, and whether soak sits in the same week. We do not publish a week count as a guarantee. The quote names the timeline after a free 1-hour load test on a staging URL, so the estimate rests on what you actually run.

The breaking point in your own units, the bottleneck named, what to change, and what was not tested. A report only a performance engineer can read changes nothing, so we write it for a product owner. It is the load slice of the full performance report.

Most engagements land at $25 to $49 an hour blended. Price follows the surface, the peak you named, and whether soak sits in the same week. A free 1-hour load test on a staging URL shows the surface before anyone writes a quote.
