Expose bottlenecks before they become incidents

We help you find the limits of your software before your users do. Never lose a customer to performance issues again.

No more manual scripting Works with your stack Evidence-backed diagnosis

Load testing that starts with how your product is actually used.

Traditional load testing starts with hours of guesswork and scripting that don't account for user behavior. Scaley learns how your product is actually used, then simulates that behavior at scale to find the hidden bottlenecks.

01 / Learn

Let us learn your product's user journeys.

We first navigate your product to find all the user journeys, then capture how each action behaves, and finally replay them across hundreds or thousands of simulated users.

02 / Diagnose

We'll find hidden bottlenecks and their root causes.

Instead of another dashboard to interpret, we provide the source of the bottleneck backed by evidence from traces, metrics, and profiling data.

How it works

You bring us on, we do the rest

Four steps. One connected view of how far your application can go.

Choose a user journey or let us discover one

We learn the actions, timing, and system behavior behind every step.

Create realistic traffic

We turn that journey into traffic that preserves the sequence, timing, and variation of real product use.

Trace the whole system

We follow each request across your application, databases, caches, and dependencies as traffic climbs.

Get a clear diagnosis

Scaley connects the workload to your system signals and surfaces the bottleneck, impact, and evidence needed to fix it.
