FREE AI WEBSITE TESTING TOOL
Test your web app for free.
Review the evidence before your next release.
BreakYourApp builds application understanding from supplied product context, authorized browser exploration and previous runs. A shared application map connects observed behavior with security checks and supported read-only QA beta assertions. Define critical journeys and expected outcomes in your product workspace; coverage depends on the checks available in your deployment.

Who is it useful for?
SaaS founders and small product teams can use a scan to get an additional view of their staging app. QA engineers can configure a critical workflow, inspect the assertions and review potential failures. It works best when you provide the expected business result and use the findings alongside human testing.
What can you test?
Explore a web application
Navigate reachable pages and exercise supported forms and controls within the scan budget.
Checks depend on discoverable links, compatible authentication and supported interactions.
Verify a critical workflow
Define exact steps, unique expected text and optional row count, refresh and request assertions.
A completed action is not a passed business assertion. Supply the intended outcome.
Check a declared private API
Compare a configured JSON GET endpoint across owner, second-account and anonymous sessions.
Provide a verified owner baseline, dedicated test accounts and a unique private-data marker.
Review an actionable report
Inspect findings by severity, reproduction steps, available evidence and the detailed test plan; export the report to PDF.
Potential issues require human review. Blocked and untested checks remain visible.
How to run a useful first scan
- Choose a reachable staging application you own or are authorized to test. Use disposable test data.
- Connect your product in BreakYourApp. Describe its purpose, define critical journeys and select the authorized environment and focus areas.
- For a critical journey, provide exact control labels and a unique expected result. Add row-count, refresh and observed-request expectations where appropriate.
- For privacy checks, configure separate test accounts, a primary-only resource and its private marker. Add the known same-origin JSON GET endpoint if you want to compare API access.
- Review tested areas, passed and failed assertions, blocked checks and untested cases. Follow reproduction steps and confirm findings with your team.
- Fix a finding and rerun the same settings to compare behavior.
How to judge the result
Start with the coverage: which pages and flows were reached, which assertions ran, and which checks were blocked? Then review severity, expected versus actual behavior and available browser or network evidence. Zero findings with little coverage tells you less than a well-observed workflow with explicit expectations.
Our controlled SaaS simulation detected five seeded defects across fourteen runs, using predefined scenarios and expected outcomes. That supports the configured checks in the fixture; it does not establish an unknown-bug discovery rate on customer apps. Read the reproducible methodology and limitations.
Common questions
Is the AI website testing tool free?
BreakYourApp is currently free. No credit card, subscription or scan credits are required. Page, action, time and fair-use limits still apply.
Can I test a web app behind login?
Add a dedicated test account for compatible authentication. A login flow requiring an unsupported challenge may prevent coverage; the report should show the blocked area. Prefer a staging environment with disposable data.
Does it check server behavior or only the UI?
A configured journey can verify an observed request to a declared endpoint, including its HTTP response. Optional private JSON checks inspect a declared response in isolated sessions. The scanner does not inspect your internal server code or every API endpoint.
Can a scan prove that my application is secure?
No. Access-control checks cover the declared resource and marker. A clean result does not establish that all fields, roles, sessions or endpoints are protected, and this is not a complete penetration test.
How is a passed test different from an action that completed?
A completed action means a control was exercised. A passed check means the defined expected outcome was observed. Failed means an observed contradiction; blocked means there was not enough evidence to complete the check. Proposed cases that did not execute remain untested.
