Web apps avoid an app-store review but inherit a wide public surface. A wrong DNS record, permissive database policy, leaked preview credential, broken password email or destructive migration can block the release even when the homepage looks finished.

Use the broader app launch checklist for release governance. This web-specific version is organized around what a builder can verify before opening the URL to real users.

Confirm the canonical domain, www behavior, HTTPS certificate, DNS owner, registrar recovery contacts and renewal method. Redirect every alternate production origin consistently. Keep preview domains out of canonical metadata and search discovery.

List who owns the repository, Railway/Vercel/Cloudflare or other hosting project, database, authentication, email, storage, analytics, model provider and payment accounts. The product owner should control billing and recovery. A contractor or AI-tool workspace can have access without being the only path to the service.

Create two ordinary users and at least two organizations or workspaces if the app is multi-tenant. Verify reads, edits, exports, deletes, invitations and administrative actions across the boundary. Change identifiers in URLs and requests; hidden UI controls are not authorization.

Test sign-up, sign-in, sign-out, session expiry, password or magic-link recovery, email changes and invitation reuse. Confirm that production callback URLs are exact and old preview origins are removed. Use server-side checks for every sensitive action.

The OWASP Application Security Verification Standard provides a structured source for authentication, session, access-control, input and data-protection requirements. Apply a level proportionate to exposure and consequence rather than claiming that a short checklist certifies the application.

Inventory data collected through forms, accounts, uploads, analytics, logs, support and model calls. For each category, record purpose, storage, access, retention, export and deletion. Publish privacy information that matches the deployed behavior.

Keep customer data and powerful production credentials out of preview environments. Verify database backups by restoring one into an isolated environment. Record how much data could be lost and how long recovery actually took.

If users can upload files, validate size and content, authorize downloads, isolate untrusted content and define deletion. If the app sends data to an AI provider, make that boundary deliberate and avoid logging private prompts or full documents without need.

Write the critical journeys as outcomes: create an account, complete first value, return to saved work, recover access, pay if applicable, export or delete data. Test them in production configuration on current mobile and desktop browsers, narrow and wide screens, keyboard-only navigation and slower connections.

Check loading, empty, validation, offline or failed-request, retry and partial-success states. A generated happy path may leave these states undefined. Test a fresh account as well as an account with realistic data volume.

WCAG 2.2 is the normative accessibility reference. Automated scanning can identify some failures but cannot establish that the whole task is usable.

Measure representative pages, not only the landing page. Capture server response, loading, rendering and interaction behavior on realistic mobile hardware and networks. The web.dev performance course provides current guidance for diagnosing loading and responsiveness rather than optimizing a single synthetic score.

For every external service, test success, rejection, timeout and delayed success. Add request limits, payload limits, concurrency controls and provider budgets where an action costs money. Protect payment, email and webhook endpoints against duplicate processing; retries should not create duplicate charges, messages or records.

Remove test keys, stale webhooks, unused packages and abandoned preview environments. Record the runtime, lockfile, build command, migration command and required environment variables without copying secret values into documentation.

Monitor outcomes rather than server uptime alone. The Google SRE Workbook's monitoring guidance emphasizes signals that reflect user-facing service behavior and actionable failure.

At minimum, know whether the app is reachable, users can authenticate, the core task succeeds, error and latency rates are abnormal, queues are stalled and external-service spend is rising. Alerts need an owner and first action. An alert that nobody receives is not a control.

Use structured logs with request context but exclude secrets and unnecessary personal data. Confirm that error pages do not expose stack traces, SQL, environment configuration or provider payloads.

Identify the last known good application deployment and practice rolling back to it. Handle database changes separately. Backward-compatible migrations reduce risk; a code rollback cannot undo deleted or transformed data.

Prepare a feature flag or kill switch for risky integrations. Record who can enter maintenance mode, disable outgoing work, rotate credentials and communicate an incident. Rehearse the sequence with the person who would actually perform it.

Provide a monitored support address, clear terms and privacy links, honest pricing or access expectations and a way to report security concerns privately. Decide what happens when a user asks for deletion, export, refund or help.

Define the first audience and support capacity. A controlled beta is a real launch strategy, not a failure. Limit user count, data types or expensive features when evidence is incomplete. Explain those limits plainly.

Publish the app on Heyviber with its maturity, stack and exact feedback request. Avoid a generic “thoughts?” prompt; ask about the user journey or risk that determines the next release.

Freeze non-essential features. Run critical journeys against the actual domain. Confirm email authentication and links, monitoring, backup recency, rollback access, open high-risk defects and on-call contact. Inspect canonical metadata, robots rules and sitemap output so preview or private pages do not become search results.

Name one stop/go owner. If a critical boundary lacks evidence, reduce exposure or delay. Do not convert an unresolved security or data-loss risk into launch-day experimentation.

We specialized the six-gate launch framework for browser-delivered AI products and grounded the technical checks in OWASP ASVS, WCAG 2.2, web.dev performance guidance and the Google SRE Workbook. The workflow also reflects common deployment boundaries in the Heyviber stack: dynamic authentication, databases, email, external AI services and Railway-style production environments.

Pair this checklist with a permissioned launch artifact from a real project, such as a redacted domain checklist, two-account authorization test, monitoring view, or successful restore record. The artifact must not expose credentials or imply independent certification.

Mark each section pass, constrained pass or stop. A constrained pass names the limit and owner: invited users only, invented data only, manual approval for an expensive action or a lower daily cap. Launch when the residual risks are explicit, proportionate and recoverable—not when the preview simply looks complete.
