Load test login flows
as users experience them
LoadForge launches real Chromium browsers at scale — not just HTTP requests. Measure Core Web Vitals, render times, and UX quality under genuine production-like load.
HTTP mocking misses what users see
Headless HTTP tools cannot measure paint, layout shift, or JavaScript execution. LoadForge spins up real Chromium instances that render every page the same way your users do.
Real user flows
Script multi-step journeys: login, search, add-to-cart, checkout. Every step runs in a real browser.
Core Web Vitals under load
Measure LCP, CLS, and INP while hundreds of concurrent browsers hammer your app.
Visual regression detection
Compare screenshots across test runs to catch UI regressions that HTTP-only tools miss entirely.
Script recording
Record browser sessions and replay them as load scripts. No code required.
JavaScript execution metrics
Track JS heap size, long tasks, and rendering pipeline bottlenecks at every concurrency level.
Global browser fleet
Run Chromium instances from multiple regions to understand geo-specific rendering performance.
From recording to results in 3 steps
Record a browser journey, scale it across a fleet of Chromium instances, and analyze real user metrics under load.
Record or script your journey
Use the LoadForge recorder to capture clicks, form fills, and navigation. Or write Playwright-style scripts for advanced control.
Launch a browser fleet
LoadForge spins up hundreds of real Chromium instances across your chosen regions. Each browser executes the full journey independently.
Analyze real user metrics
Get per-step timings, Core Web Vitals, screenshots, and error traces. Compare runs to track regression over time.
See your app through your users' eyes, at scale
Real browsers capture what HTTP tools miss: paint timing, layout shifts, JavaScript execution, and visual fidelity under load.
Start browser testing
Multi-step journey execution
Record or script complete user flows — login, browse, add to cart, checkout — and replay them under load with real Chromium browsers.
Core Web Vitals dashboard
Track LCP, CLS, and INP at every concurrency level. See exactly when your frontend starts degrading.
Visual comparison
Side-by-side screenshot comparison across test runs to spot visual regressions automatically.
