DON'T FIND OUT YOUR APP FALLS OVER BY HAVING IT FALL OVER.
You shouldn't discover your app's breaking point when 50 people hit it at once during a launch. By then you've already lost revenue, trust, and the momentum you spent weeks building. A stress test finds the saturation point in a controlled environment — so you know exactly where it starts to degrade before real traffic arrives.
- +k6 load test run against your staging environment
- +Saturation point documented — you'll know exactly where the app starts to degrade
- +Performance report with specific recommendations
- +Cloud cost review included
- +Delivered as a written report with actionable next steps
YOU HAVE NO IDEA WHAT HAPPENS WHEN REAL TRAFFIC HITS.
Your app works for you. It works for the five beta testers who poked around. But you have absolutely no idea what happens when 20, 50, or 200 people hit it at the same time. The database might lock. The API might throttle. The server might run out of memory. You don't know — and by the time you find out, it's launch day and the damage is done.
Vibe-coded apps are especially vulnerable because AI tools don't optimise for concurrency. They make it work for one user. Scaling is a completely different problem — and it's one you need to solve before you go live, not after.
SETUP. SIMULATE. BREAK. REPORT.
James configures k6 against your staging environment — same infrastructure as production, no risk to real users. If you don't have staging, he'll help you set one up.
Realistic traffic patterns simulated at increasing scale — not just raw requests, but user flows that mirror how real people actually use your app. Login, browse, transact, repeat.
The test ramps up until the app starts to degrade. James documents the exact point — how many concurrent users, which resource bottlenecks first, and what the symptoms look like.
You get a written report with the saturation point, the bottleneck chain, cloud cost observations, and specific recommendations for what to fix and in what order.
NOW YOU KNOW YOUR LIMITS. APP PULSE WATCHES THEM IN PRODUCTION.
A stress test tells you where your app breaks under load. But load patterns change as your business grows. Choose an App Pulse tier to keep watch going forward — so you'll know when you're approaching that saturation point again with real traffic.

No. The test runs against your staging environment, not production. If you don't have a staging environment, James will help you set one up as part of the engagement.
k6 is an open-source load testing tool built by Grafana Labs. It simulates realistic user traffic against your app and measures how it responds under increasing load. It's the industry standard for this kind of work.
It's the exact number of concurrent users or requests where your app starts to degrade — slower response times, errors, timeouts. Knowing this number means you know exactly when to scale, before your users experience the problem.
Most stress tests are completed within 3–5 business days, including the report. Complex apps with multiple services or APIs may take longer.
You know your limits. The natural next step is choosing an App Pulse tier to keep watching your app in production — so you'll know when you're approaching that saturation point again with real traffic.
Yes. The stress test runs against a URL and simulates user flows. It doesn't matter who built the app or what tools they used.
