For AI-built web apps

Your UI said success. Did the system actually succeed?

E2EProof executes an important user flow, verifies the independent backend outcome, and produces evidence for what passed or failed.

No claim of complete coverage. A pass applies only to the configured contract, data and environment.

claim: One click stores exactly one lead

[1] Fill and submit form       PASS
[2] Visible confirmation       PASS
[3] POST /api/leads = 201      PASS
[4] Backend read-back count=1  FAIL

VERDICT: UI success was false.
Evidence: report.html + trace + manifest
Outcome evidence

One claim. Several independent observations.

The product is designed for flows where visual checks are not enough: lead capture, checkout, account actions, webhooks and external AI providers.

01

Act like the user

Run a real browser flow with stable accessible locators and isolated state.

02

Read the side effect

Check network count, response status and a separate backend read-back.

03

Keep evidence

Generate HTML, JSON, JUnit, traces and tamper-evident manifests.

Would this catch a failure you care about?
