Core Feature

See the reasoning behind every click.

Every AI session includes a step-by-step thinking trace — explaining exactly why users click, hesitate, or abandon. Not just what happened, but why.

Thinking trace — Session #247

[1.2s] Found 3 pricing cards. “Pro” is centered and highlighted.
[2.8s] Comparing features between Pro and Team. Scrolling down.

Test with zero traffic.

Run 1,000 sessions before going live. Identify conversion killers, broken flows, and accessibility barriers — without burning real user goodwill.

Core Feature

Every user.
Every edge case.

Simulate users across age, tech literacy, accessibility needs, location, and income. Find the edge cases that matter before real users find them for you.

Real Browser Execution

Each AI persona controls a real Playwright browser — screenshots, actions, and network requests.

CI/CD Integration

Trigger tests from GitHub Actions or any CI pipeline. Catch regressions before production.

Multi-Model Support

Choose Claude Sonnet 4 for deep reasoning or Haiku 3.5 for high-volume runs.

New Feature

Test pages behind login.

Configure authentication once. Every AI session reuses the same auth context — storage state, cookies, tokens, or real login flows.

auth:
  method: storage-state
  storage_state:
    path: ./auth/state.json
    # Captured from a real browser session
    # Contains cookies, localStorage, sessionStorage

Export your browser's full session state — cookies, localStorage, and sessionStorage — into a JSON file. SimuTest replays it in every AI session.

Fastest setup for complex auth flows (OAuth, SSO, MFA).
