How do I know if my SaaS is launch-ready?

When the journeys that make or lose money have been exercised in production conditions: sign-up and sign-in, payment through to access, one user never seeing another user’s data, the important emails, and what happens when something fails. The self-assessment on this page lists 39 questions; every “I don’t know” is a point to verify. Being able to answer yes is a start — having checked it is the evidence.

Can an AI-generated app go into production?

Yes, and many do. The tool that wrote the code does not decide whether it is ready; what was checked does. AI builders are often fast on the visible part and less careful about access rules, webhooks, error states or secrets. Those are the points worth verifying before real customers arrive.

What should I test before enabling Stripe?

At least: a full payment in the environment that is really deployed; access granted by the server from a verified webhook, never by the “thank you” page; the same webhook replayed without double access; a declined card and a cancellation; a refund that removes access. Use test keys for all of it before switching to live keys.

Can you review a Lovable or Cursor project?

Yes. Lovable usually produces a React (Vite) application with Supabase; Cursor and Claude Code projects are often Next.js. For the review I need the deployed application and, depending on the scope, the code — Lovable can sync the project to GitHub. Bolt, Replit and code written with ChatGPT work the same way.

Does ShipCheck replace a technical audit?

No. ShipCheck is a free checklist that helps you check the essentials yourself; it inspects neither your code nor your deployed configuration. A Launch Rescue review produces verified findings, labelled with their evidence level, and a written launch recommendation. They work well together: ShipCheck first, then the points you could not settle.

Does the audit include code fixes?

No. The Launch Audit from CHF 390 delivers findings, a prioritised plan and a launch recommendation, without touching your code. Fixes are a Launch Fix Sprint or Go-Live Support, quoted on the blockers named in the report — or Code Rescue for one precise defect.

Can you deploy the app for me?

With Go-Live Support, I can assist with the deployment if you authorise it in writing, then verify the application during an agreed window after the release. I never deploy to your production on my own, and no package promises zero downtime.

What access will you need?

Nothing for the brief. After qualification and payment, depending on the scope: the deployed URL, test accounts, read access to the code, and read-only access to the relevant service settings. Least privilege, test keys where possible, removed at the end. Never a password or a production key by email.

Launch Rescue · Ready for production?

Your app is ready.But is it ready for real users?

Before your first paying customer, check the things your AI builder may have missed.

A site that loads is not necessarily a product ready for customers. I check the critical journeys, the payments and the failure points before your launch.

01 — What gets checked

What gets checked before launch.

Eight areas where an application generated or accelerated with AI often breaks at the first real customer. Often, not always: yours may have none of these problems. The review is how you find out.

01
Authentication
Sign-up, sign-in, password recovery, sessions, and above all: who may do what, checked on the server.
Supabase Auth · Auth.js · Clerk · Firebase Auth
Answer this area’s questions →
02
Payments
Checkout in the right environment, status verified server-side, signed webhooks replayed without duplicates, access that follows the payment — refunds included.
Stripe Checkout · Billing · webhooks
Answer this area’s questions →
03
Data access
Database permissions, RLS policies, a test with two accounts: one user never sees another user’s data. Backups and restore.
Supabase · PostgreSQL · Firebase
Answer this area’s questions →
04
User journeys
A stranger completes the key journey, on mobile, on a slow network, through a server error, an empty screen, a tab closed halfway.
Mobile · keyboard · error states
Answer this area’s questions →
05
Emails
Important emails arrive, from an authenticated domain, and a failed send leaves a trace someone looks at.
Resend · SendGrid · Postmark · SPF/DKIM/DMARC
Answer this area’s questions →
06
Operations
Production separate from development, secrets out of the code, visible errors, reviewed dependencies, a way to roll back.
Vercel · Netlify · logs · monitoring
Answer this area’s questions →
07
Acquisition and analytics
Indexable pages, a sitemap, correct robots and canonical rules, and at least one conversion event that really reaches the analytics tool.
Search Console · analytics
Answer this area’s questions →
08
Privacy and trust
Privacy notices, sensitive data kept out of logs, consents where they apply, a way to reach you — and the list of what a lawyer should review.

03 — Evidence levels

Four levels of evidence. Never mixed up.

Every finding in the report says where it comes from. A declaration is not presented as a fact, a tool signal is not presented as a verification, and what was not checked is written down as such.

01User-declared: You say so; nobody has checked it yet. Useful to steer, never proof.
02Tool-observed: An automated tool reported it (scan, test, inspector). A signal, to be confirmed in the real context.
03Expert-verified: Reproduced, tested or inspected by the person who signs the report, with the evidence described.
04Not checked: In scope but not checked (access, time, environment). Stated as such, never assumed fine.

A “not checked” point is never assumed to be fine.

04 — How it works

Nothing is paid before a written scope is accepted.

Step 1 : You send a brief.
Five short steps: the product, the stage, what worries you, what is at stake, your details. With your self-assessment summary if you like. No access, no password.
Step 2 : I qualify the request.
I read your brief myself, ask what is missing, then confirm the package. If it is not a fit — or too early — I tell you.
Step 3 : Written scope and quote.
The journeys and integrations checked, what is excluded, the acceptance criteria, the price, the timeline. You accept them in writing before paying.
Step 4 : Payment, then access.
Online payment. Access is set up afterwards: the minimum needed, read-only or with test accounts where possible, removed at the end.
Step 5 : Review, report, decision.
I check the agreed scope, fix what the quote includes, and deliver a report: findings, prioritised plan, launch recommendation, handoff.

05 — Packages

Three packages. A written scope before you pay.

Starting prices, in CHF. The final price is written in the quote, after your request has been qualified: nothing is charged on the strength of the form alone.

No package guarantees zero downtime, zero vulnerabilities or complete compliance.

06 — The report

A report that says what was checked. And what was not.

Every engagement ends with a launch-readiness report in your project space, printable. Visible to you only.

A — Executive summary
The product, the checked scope, the launch target, the overall assessment and its limits.
B — Findings
For each: identifier, area, evidence source and level, expected and observed behaviour, business consequence, severity, recommended action.
C — Prioritised plan
Stop-ship · before launch · after launch · optional improvement.
D — Release decision
One of the four recommendations below, with its reasoning.
E — Proposal
Where useful: the fix scope, acceptance criteria, timeline, price and explicit exclusions.
F — Handoff
Checks completed, checks that could not be completed, outstanding risks, monitoring advice, next actions.

The four possible decisions

No identified blocker within the checked scope
Within what was checked, nothing stands in the way of a launch. It says nothing about what was not checked, and does not guarantee the absence of defects.
Launch with documented risks
No blocker identified, but known risks remain open. They are listed, with their consequence and what monitors them.
Address critical blockers before launching
At least one stop-ship point was found. Fix it — and verify the fix — before opening to real customers.
Insufficient evidence to recommend a launch decision
What could be checked is not enough to recommend launching or not. The report says what is missing.

The report never declares an application “safe”, “secure” or “bug-free”.
A decision only covers what was checked.
What could not be checked is listed, with the reason.

07 — Who, what, how

One person, a scope, evidence.

Who performs the review: Me, Danilson Ramos, a product engineer in Zürich. I build and run Next.js, Supabase and Stripe applications in production. The person who reads your brief is the one who performs the review and signs the report: no subcontracting.
What can be inspected: The deployed application, the code (repository or copy), the deployment configuration, logs, and read-only the relevant settings of your services (Stripe, Supabase, email). An automated tool may complement this; its signal is always labelled as such.
What you receive: The A-to-F report in your project space and, for a fix, the code delivered as a pull request, branch or patch. Nothing is deployed without your written approval.
What is excluded: Anything outside the written scope, penetration testing, compliance audits, legal advice, new features.
How access is handled: After qualification and payment, with your agreement: the minimum needed, read-only or with test accounts and test keys where possible, time-limited, removed at the end. Never a password by email. An NDA is available.
If critical problems are found: I tell you right away, without waiting for the report, with what I observed and what I recommend. The fix is not improvised: it is in the quote, or it gets a separate proposal you accept — or not.

This review is not a penetration test, legal compliance certification, or guarantee that no bugs remain.
