Performance and load testing before the traffic spike, not during it
Realistic load profiles against your critical endpoints and journeys, with latency budgets that flag regressions release over release. Find the slow query in staging, not on launch day.
Performance problems rarely arrive as outages. They arrive as a p95 that creeps from 300ms to 900ms over six releases until a sale, a launch or a busy Monday tips it over. By then nobody knows which change caused it.
QAShift runs load tests as part of your release process, compares each run with the last and alerts when latency, throughput or error rates regress, so a slowdown is traced back to the change that caused it.
What our performance testing covers
Load and stress profiles
Steady, ramping and spike traffic patterns based on how your users actually arrive.
Latency budgets
p50, p95 and p99 thresholds on critical endpoints, enforced on every run.
Release-over-release trends
Each run is compared with the previous baseline so regressions are tied to a release.
Breaking points
How far the system scales before errors climb, and which component gives way first.
Front-end performance
Page load and interaction timings on the journeys customers use most.
Error rates under load
Timeouts, 5xx responses and queue backlogs that only appear at volume.
What it catches before your customers do
- A new ORM query adds 600ms to every dashboard load
- Checkout times out during a flash sale
- Autoscaling kicks in too late and the queue backs up
- p95 latency doubles across three releases and nobody notices
Two ways to get it done
Run it yourself
Every Verity plan can generate load tests for your endpoints and run them from your CI with configurable profiles.
We run it for you
Performance is an add-on on Starter and Growth ($179/mo) and included on Scale. Your engineer designs realistic profiles and investigates every regression.
What you get
- Load test scripts in your repo
- Latency and error trends by release
- Regression alerts in Slack
- A bottleneck summary on managed plans
Frequently asked questions
Do you run load tests against production?
We recommend a production-like staging environment. Production runs are possible with agreed limits and schedules on managed plans.
What tools do the load tests use?
Load tests are generated as code and run from your CI, so results and scripts stay with you.
How much does performance testing cost?
Load tests are included on every self-serve plan. On managed plans performance is a $179/mo add-on for Starter and Growth, and included on Scale.
Can you test front-end performance too?
Yes. Journey tests record page load and interaction timings, so slow screens are caught alongside slow APIs.
