Home / Launch checklist

One launch.
Twelve checks worth making.

Work through your AI app’s public exposure, access rules and release controls. Mark what you reviewed, flag what needs work, and come back after your next change.

Start the checklist ↓

A working review, not a security score. Your selections are self-reported. This tool does not run scans or approve a launch. Test only apps and services you own or have explicit permission to assess.

Start with what the browser can see.

01
Public-file scan can help

Keep privileged keys out of the browser.

Review the deployed HTML, JavaScript and embedded source maps, plus your build settings. Public Supabase or Firebase configuration is not automatically a secret. Keep service-role, billing, email and model-provider secrets server-side.

What evidence should I keep?

Record where each privileged key is used. If one leaked, revoke or rotate it, remove it from the browser build and rescan; deleting the string alone is not enough.

02
Verified website checks can help

Check what your build makes public.

Review the deployment output for environment files, Git metadata, backups and source maps containing sensitive source. Source maps can be intentional; inspect what yours disclose. Test only your own deployment.

What evidence should I keep?

Keep a deployment review showing that sensitive artifacts are excluded or denied. StackSnack’s deeper exposed-file checks need website ownership verification.

03
Codebase review + partial URL checks

Review the actual dependency inventory.

Inspect the lockfile, direct and transitive dependencies with your package ecosystem’s tools. Triage advisories against the versions and features you deploy, then review updates and run regression tests.

What evidence should I keep?

Keep the audit output, update decisions and test results for this release. A URL scan can recognize some public library versions; it cannot inventory your private codebase.

Understand the scan’s scope ↗

Test the boundaries behind the login.

04
Access-rule review + approved backend checks

Test what a signed-out visitor can access.

Use synthetic data in a test environment. Review exposed tables, grants and policies in Supabase, or Firebase access rules. Try the same database request without a user session; do not assume a login screen protects the data.

What evidence should I keep?

Record the expected and observed signed-out result for each private resource. Database tests need separate backend ownership approval; website verification alone is not sufficient.

05
Application-specific manual testing

Try two users—and two tenants, if you have them.

In a test environment, let Alice create a record, then try reading, changing, exporting and deleting it as Bob. Repeat across tenants and roles, including invitations, admin routes and file URLs. Check the server’s response, not just hidden buttons.

What evidence should I keep?

Keep an allow/deny test matrix covering own records, another user’s records, tenant boundaries and intended staff access. A public URL scan does not establish these permissions.

06
Storage-rule review + approved backend checks

Review uploads and private-file access.

With synthetic files, test upload limits, allowed file types, anonymous listing and cross-user download access. Review public buckets, private objects and signed-link expiry against the intended product behavior.

What evidence should I keep?

Keep successful allowed-access tests and denied unauthorized-access tests. Separately approved scanner storage checks can help; they do not prove all file permissions are correct.

Review database and storage rule limits ↗

Make the server enforce the rules.

07
Manual authentication review

Protect accounts and administrator access.

Test sign-in, sign-out, recovery and session expiry. Require strong authentication for privileged users, review session-cookie settings, and ensure changing a browser value cannot grant an administrator role.

What evidence should I keep?

Keep account-flow test results and an administrator access review, including MFA or passkeys and the recovery process. A security header check does not test all these flows.

Read OWASP’s authentication guidance ↗
08
Header scan + configuration review

Check the production configuration.

Review HTTPS and redirects, response headers, session cookies, allowed origins, debug endpoints and provider permissions. Configure these for the services the app actually uses; do not blindly paste a generic policy.

What evidence should I keep?

Keep a response-header review and deployment-setting checklist. Test normal app behavior after changes; HTTPS and a CSP are useful controls, not proof of complete security.

Start a public-file and header scan ↗
09
Code review + authorized tests

Put validation and abuse limits on the server.

Validate types, size and allowed values on the server. Use parameterized database queries, enforce authorization before work, and bound costly endpoints such as AI calls, uploads and scans. Treat browser validation as convenience.

What evidence should I keep?

Keep tests for malformed, oversized, repeated and unauthorized requests, plus observed rate-limit behavior. Use controlled test volumes; a URL scan is not a load test.

Read OWASP’s input-validation guidance ↗

Know what happens after launch.

10
Manual review · if applicable

Protect payments and expensive actions.

If you bill users, verify provider webhook signatures, handle repeated events safely and grant entitlements on the server. Enforce spending limits and permissions before invoking paid APIs. If none of this applies, choose Not applicable.

What evidence should I keep?

Keep sandbox payment tests for success, failure, duplicates, cancellation and unauthorized access. Never trust a browser success page or client-supplied plan as payment proof.

11
Operational review

Practice recovery and choose useful alerts.

Restore a backup into an isolated test environment and check the result. Restrict access to logs, redact secrets and personal data, and decide who responds to serious errors or suspected exposure.

What evidence should I keep?

Keep the restore test date, recovery steps and responsible contact in your private project records. Confirm alerts reach the intended person without disclosing sensitive report contents.

12
Rescan + manual follow-up

Retest the release, including what was skipped.

Review findings, apply a reviewed fix, deploy and repeat the relevant tests. Run a fresh scan on the deployed version and read coverage warnings. Reopen this checklist after authentication, policy, dependency or deployment changes.

What evidence should I keep?

Keep a private release record with the scan, manual test results, known limitations and unresolved work. No checklist or clean scan guarantees an app has zero vulnerabilities.

Run a fresh authorized scan ↗

Keep this handy for the next deploy.

Bookmark this page, download your review, or save choices on this device. Revisit after changes to permissions, authentication, dependencies or deployment settings. Saving is optional, uses this browser’s local storage, and does not sync between devices or website addresses. Anyone using this browser can see saved choices. Keep exported project reviews private.

A checklist is a starting point, not a penetration test, compliance certification or guarantee of zero vulnerabilities. Arrange a specialist assessment when your app’s risk calls for one.
