Service · Finish & launch

We finish vibe-coded apps and take them live.

The demo works and the screenshots look great, but real auth, billing, emails and deploys are still faked or missing. That last 20 percent is the hard part, and it is what we do: we take your prototype to a production app you can charge money for, then keep watching it after launch.

01The last mile

What "almost done" usually still needs.

Real authentication

Sessions that survive refreshes, password resets that work, roles that actually gate pages, OAuth that handles the unhappy paths. The demo login becomes an account system.

Billing that charges

Stripe products, checkout, webhooks, invoices, upgrades, cancellations and the dunning emails. Test-mode buttons become revenue.

Transactional email

Signup, receipts, resets and alerts, from a domain with SPF, DKIM and DMARC set up so they land in inboxes instead of spam.

Production deploys

A real environment with environment variables, migrations, SSL, a rollback path and zero-downtime releases, instead of pushing to the preview URL and hoping.

Performance and edge cases

The N+1 queries, the empty states, the double-submit bugs, the mobile layouts and the timezone math the prototype skipped.

Monitoring from day one

Uptime checks, error alerts and a status page, so the first user-facing failure is a notification to you, not a refund request.

02How we work

Your repo, your review, our engineering.

We work inside your repository in reviewable chunks, keep you in the loop in plain language, and never hold your code or infrastructure hostage. You own everything at every step.

  • Fixed scope and price agreed up front, milestones you can see
  • Changes land as pull requests with clear descriptions
  • Security built in as we go, not bolted on at the end
  • Launch includes monitoring, alerts and a rollback plan

FAQ

Common questions

What does it cost to finish a vibe-coded app?

+
A fixed price per agreed scope, quoted after we look at the repo and hear what is missing. Typical projects cover auth, billing, email and deploy as separate milestones, so you can stop after any milestone with a working improvement in hand.

Which platforms and stacks do you take on?

+
Apps started in Lovable, Bolt, Cursor, v0, Replit or any AI-assisted workflow, on stacks like Next.js, Supabase, Firebase, Laravel, Node, Django and Rails. If the prototype runs, we can usually take it the rest of the way.

Do I keep ownership of the code?

+
Completely. We work in your repository, on your accounts, with your infrastructure. Every change is a reviewable pull request, and you can end the engagement at any milestone without losing anything.

How long does a typical finish take?

+
Auth, billing and deploy for a single-product SaaS typically lands in two to four weeks. We report progress against milestones, and critical blockers surface immediately rather than at a weekly meeting.

Is security included or a separate service?

+
Baseline security is built into everything we ship: no keys in the client, rate-limited auth, validated inputs, hardened deploys. A full security audit of code we did not write is the separate audit service, and combining both is common.

What happens after launch?

+
Your app runs on the Defen.so platform: uptime monitoring, managed WAF, scans and multi-channel alerts, from the free tier up. You are not dependent on us afterwards, but we are one email away.
