Test Scenarios
- Build a journey once. Reuse it everywhere.
- Step-by-step playback with pass/fail per step.
BEYOND HTTP-SCRIPT TESTING
Performance tests that see what your users see.
Every virtual user is a real browser. The Core Web Vitals you get back match what your customers actually feel. Not what an HTTP script pretends they feel.
The platform
Performance reports built for engineers.
Web Vitals, network logs, console logs, and session video for every virtual user. Not aggregate percentiles. Every session is addressable.
A report that doesn't lie.
A failure at peak isn't a percentile bump. It's a session. You open it, watch the video, read the logs, and find the request that broke.
How it works
The lineup
One platform. Three products.
Build a scenario once. Use it as a performance test, a CI smoke test, or a continuous monitor. Same forensic detail comes back every time.
Performance Testing
Real-browser performance tests at any scale. Track Core Web Vitals per session and per URL. Find what breaks before peak does.
Tour the platformTesting Suite Soon
Run the same scenarios as deployment-gate smoke tests. Catch Web Vitals regressions before they ship, with the per-session detail of a full performance test.
Join the waitlistMonitoring Soon
Run your scenarios continuously from chosen regions. Alert on Web Vitals regressions, with session video to debug them.
Join the waitlist What's in the box
Eight capabilities. Together they reconstruct any session.
Configured once at the project level. Captured for every virtual user. Open any session and see exactly what happened.
Datasets
- Inject unique data into every virtual user.
- Search terms, SKUs, UTM parameters, accounts.
Popup Handlers
- Dismiss cookie banners, modals, and consent dialogs.
- Configure once at the project level.
Regional execution
- United Kingdom, Germany, Brazil, and more.
- Configurable browser locale and timezone.
Core Web Vitals capture
- LCP, INP, CLS, FCP for every virtual user.
- Aggregated by run, addressable per session and URL.
Network Logs
- Every request, every user, every byte.
- Searchable across millions of rows per run.
Console Logs
- Every console message from every virtual user.
- Deduplicated and counted across the run.
Session Video
- Watch any virtual user's browser end-to-end.
- Step playback timestamped to the millisecond.
In practice
How engineering teams use Evaluat.
Capacity rehearsals
Push critical paths to 5x, 10x, 20x normal traffic. Find the ceiling before customers do.
Release validation
Compare two test runs side by side. Catch the regression in the candidate build before it ships, not after a customer reports it.
Web Vitals budgets
Set thresholds for LCP, INP, CLS at the URL level. The build fails when a page busts its budget. Not later. Now.
Third-party tag analysis
Find the analytics tag, A/B test, or chat widget that's costing you 600ms of LCP. The waterfall makes it obvious.
Regional performance
Run the same scenario from London, Frankfurt, or São Paulo. Compare what your German customers feel vs your American ones.
Forensic debugging
When the performance test exposes a bug, the session video, network log, and console output for that user are all linked. Find it in minutes.
