For AI-built apps

Keep building with AI. We'll keep it running.

You built a web app with Lovable, Bolt, v0, Replit, Base44, Cursor or Claude Code, and people already use it. We get it ready for growth: payments, data security, backups, monitoring. We also set up rules and automatic checks, so you and your AI agent can ship new features with confidence. No dev team to hire. We work with the code you already have.

About

For anyone whose app is starting to take off

Your app already has users, maybe even paying ones. Now you're planning a launch, an ad campaign or a press moment, and you want to be sure it can take the rush: it stays up, payments go through, and data stays safe.

How it will all work

  • Everyone who pays gets access, with no glitches and no need for you to step in.
  • You and your AI agent ship new features with confidence.
  • You launch ads with peace of mind: the app is ready for the rush.
  • Your data is backed up, and your app is watched around the clock.
  • Your users' data is protected, and the access rules are checked by tests.
  • Your AI and payment keys are safe, with spending limits in place.
  • Automatic tests show you what works, every time you ship.
  • An investor or a client asks about security, and you send a report.

Services

What we do

More users, more to handle. Here's what we take care of:

  1. Make payments reliable

    Stripe and other payment services. A user pays and always gets their access or subscription. Every payment is counted exactly once, even when the payment service has a hiccup.

    In Pricing: "Ready to grow" sprint.

  2. Protect access and data

    Each user sees only their own data. Admins manage the app; regular users manage only their own account. Plan limits work: paid features stay with paying users. And customer data stays safe through every update.

    In Pricing: Access & data test.

  3. Set up backups and monitoring

    Your data is backed up regularly, and we check that you can actually restore everything from the backup. If your app goes down or shows errors, you get an alert right away and hear about it first.

    In Pricing: "Ready to grow" sprint and Basic care.

  4. Move your app to your own accounts

    We move your app from Lovable, Bolt, Replit or Base44 to Supabase and Vercel accounts you own. The code, the database and the access are yours.

    In Pricing: Migration.

  5. Keep your app running when other services fail

    Your app depends on other services: payments, email, delivery, AI. When one of them is slow or down, your app stays steady: it waits, tries again or switches to a backup. Your users carry on as usual.

    In Pricing: "Ready to grow" sprint.

  6. Get ready for a rush of users

    Before you pay for ads, we check how many visitors your app can handle, what hosting will cost as they grow, and what to strengthen first. So your app is ready for a lot of new users.

    In Pricing: Speed & load.

Approach

Your project stays yours

We make it safe for you to keep building the way you like. Here's what we set up:

  • Rules for your AI agent: instruction files (CLAUDE.md, AGENTS.md) that explain how your app is built and which parts to handle with care.
  • Tests on the key user journeys: sign-up, payment, the main action in your app.
  • CI: an automatic check that lets only working changes reach users.
  • A test copy of your app (staging) to see every change before it goes live.
  • Automatic code checks (types, linters) that keep every change clean.

Everything stays in your repo and your accounts.

How we handle access →

You tell the agent what to do, it builds it, and our automatic checks make sure everything works as it should.

Check

  1. Free review

    We look at your app and send a short written report: the top 5 risks in payments, access, data, servers and hosting, ordered by what could hurt you first. Report in 3 business days. No obligation.

    Free

    Get a free review

  2. Access & data test

    Scanners flag keys and settings. We test what they can't see: can a user open someone else's data, get paid features without paying, or act as an admin? You get a fix for each real issue, ordered by risk. Report in 48 hours. Order a sprint afterwards and we deduct this price from it.

    $375

    Order a test

  3. Deep audit

    A full review of code, data, servers, hosting and payments. You get a step-by-step fix plan with estimates and a clear call: fix or rebuild. Includes the access & data test. Report in 5 business days. Order a sprint afterwards and we deduct this price from it.

    $1,100

  3. Feature sprint

    We build the features that need a developer's hand: user journeys like sign-up and checkout, UI polish, payments and integrations. Scope and price are fixed before we start. Takes 1–2 weeks.

    From $1,900

    Get a quote

  4. Migration

    Your app lives on Lovable, Bolt, Replit or Base44 hosting? We move it to Supabase and Vercel accounts you own: data, users, auth and storage. We test on a copy first, then switch. Usually 3–7 days.

    From $1,200

    Book a session

Business hours: Mon–Fri, 9:00–18:00 GMT+3. "Respond" means that within this time a developer writes to you personally: what they've checked so far and when you'll hear next. Not an auto-reply. Extra hours beyond plan limits: $150/hour. Unused hours don't roll over. The price of the access & data test or deep audit is deducted from any sprint you order after it. Cancel monthly plans anytime. Need AWS or your own servers instead of Supabase and Vercel? Quoted after a deep audit.

Why us

A developer who knows your project

The same developer from our team always works on your app. They already know your code, so there's nothing to explain twice: things get done faster, and working together is easier.

  • Production experience. Has built payments that are confirmed and counted correctly, integrations that keep working when outside services fail, and alerts that let us act before your users notice anything.
  • Knows your AI tools. Works with the same tools you do (Claude Code, MCP, Playwright, CI), knows where they shine and where they need a safety net, and explains everything in plain words.
  • Speaks your language. English or Ukrainian, with clients in Ukraine and around the world.

Case

Delivery tracking keeps working, even when partner services are down

A delivery platform with tens of thousands of business customers. It relied on outside services to find out where a shipment is and what delivery will cost.

What happened: those services were sometimes slow, and sometimes stopped responding altogether. The platform's users felt it every time.

After the fix, the platform remembers answers it has already received and doesn't ask the same thing twice. When a service is down, it shows the last known data, or a clear message instead of an error if there's none. It doesn't flood the services with repeat requests, and it writes down what went wrong so it can be fixed fast. Now users barely notice when a partner has trouble.

Case

Failed payments: from occasional to zero

A food ordering app our client built with AI. Sometimes a customer paid, but the app didn't notice: the order stayed unpaid, and the delivery never started.

Why it happened: the app got the payment notice but sometimes didn't manage to record the payment. When the payment service sent a reminder, the app thought it had already handled it and skipped the reminder.

After the fix, the app treats the job as done only once the payment is actually recorded. If something fails, the payment service sends a reminder, and this time it works. Since then, every payment reaches its order.

Your AI-built product took off. Now what?

One person with an AI agent can ship a product in an evening. Here is what happens when real users arrive, and how to keep it running without hiring a team.

FAQ

Questions we often get

Do you rewrite my app?

No. We work with the code you have and strengthen what matters: payments, data security, backups, monitoring. If something really needs a rebuild, the deep audit says so clearly, with an estimate.

Which tools do you work with?

Web apps built with Lovable, Bolt, v0, Replit, Base44, Cursor or Claude Code. Most of them run on Supabase, Vercel and Stripe, which we know well.

What's in the free review?

A short written report with the top 5 risks in payments, access, data, servers and hosting, ordered by what could hurt you first. You get it in 3 business days. No obligation.

Will you see my users' data?

No. We test on a copy of your database structure filled with generated data. The only exception is a migration, and only with your written consent for a set time window.

Can I keep building with my AI tool afterwards?

Yes, that's the point. We add tests, an automatic check before every release and rules for your AI agent, so you keep shipping features with confidence.

Who owns the code and accounts?

You do. Code, database, hosting and payment accounts stay in your name. You invite us and remove our access when the work is done.

How fast can you start?

The free review takes 3 business days, the access & data test 48 hours. For an emergency that blocks sign-up, login or payments, we start the same business day if you write before 15:00 GMT+3.

Do you work with clients outside Ukraine?

Yes. We work with clients worldwide, in English and Ukrainian. Business hours are Mon–Fri, 9:00–18:00 GMT+3.
