Turn up the crowd
Choose 10 to 500 simulated users and see when the app starts to slow down or say no.
Pressure & stress testing
Find the breaking point before your customers do.
Once people like your prototype and it does what it should, we fill it with simulated users in the Sandbox. You choose the crowd, the speed, and the date. We show you what strains first and what it would take to fix.
You set the test
A busy day, a sudden rush, or a year in an hour.
Change how people behave
Test the actions that matter to your app, including people leaving halfway, coming back, or arriving together.
Move time forward
Run days or months in minutes to check renewals, deadlines, queues, reminders, and other time-based rules.
Keep it safely pretend
Simulated users never receive real emails or texts, and they never make real payments.
What you see live
Watch the strain build.
- Active simulated users and actions each minute
- The slowest screens and the errors that appear
- Rules that correctly stop an action
- Start, pause, and reset controls for each run
What you take away
A report you can act on.
Each run is saved with the breaking point, what failed first, and a plain verdict: ready to grow, needs work before launch, or not yet. We also explain what fixing it would take, so the next decision is based on evidence instead of guesswork.
Where it fits
After the prototype. Before the real crowd.
Pressure Testing is a paid step for a delivered prototype. First, you confirm that people used it and liked it, and that it does what it should. The price is shown before you start. Some Develofi codes and contest prizes may cover it.
A simulation is a guide, not a promise about the finished app. Real phones, networks, people, and launch-day surprises still matter. We test those in a smaller real-world trial before launch.
Not ready for a Pressure Test yet?
Start with a free evaluation. We will help you find the smallest useful prototype, then you can prove demand and put it under pressure when the time is right.
