KP3 revealsVibe coding toolkit
Build your own tools for your own work. The servers, payments and email are ready.
A toolkit for people building software with AI agents like Claude Code and Cursor: servers, databases, login, VietQR bank transfer alerts, transactional email. The AI reads the docs and quotes the cost in VND before it creates anything that costs money.
- Hosted in Vietnamservers and databases
- VND by the hourpay for what you actually use
- Sandboxfree test runs
Dear friend,
If you’re looking at Vibe coding toolkit to get more customers and more revenue without taking on more work yourself, this could be the most important page you read this week.
The toolkit comes with llms.txt docs and sample prompts, so your AI agent picks the tools, estimates the monthly cost, runs a sandbox test and asks you before creating anything that costs money. A customer scans the VietQR code, the app gets the payment alert instantly and matches it to the right order.
Once you have the toolkit: in the morning, you ask AI to build a booking form that takes a deposit. In the afternoon, the first customer scans the code, the money lands in your account and the confirmation email goes out by itself.
But before I tell you what KP3 does, let me ask you one question…
Ideas die at the going-live step
- AI writes code fast, but when it’s time to go live, you get stuck on servers, databases and login.
- Taking payments and matching them to the right orders is a whole problem of its own.
- Every piece has its own provider, its own account, billed in dollars.
If you nodded at even one line above, it’s not your fault. It’s a sign that the way you work now has run out of room to grow.
The good news: there’s a faster, surer way — and you don’t have to do it yourself.
What you get
- From idea to an app people pay for. Without having to become a systems engineer.
- Scan VietQR, order matched. The app gets the payment alert instantly and matches the order. Nobody has to watch the bank statement.
- AI quotes before it creates. AI asks you before creating anything that costs money.
What’s in the package
- Servers and databases (VPS, MongoDB, PostgreSQL, MySQL) hosted in Vietnam, billed by the hour, paid in VND
- A Supabase-style database: Postgres, login, file storage, realtime
- Bank transfer alerts through virtual accounts, VietQR and webhooks. The money goes straight to your account
- Transactional email through one API, with a mailbox for AI agents
- llms.txt docs for AI to read, and sample prompts so AI picks the right tools
- If a part gets too hard, the KP3 team builds it with you: custom software, AI agents, websites

Wait… this service isn’t for everyone
Because KP3 commits to KPIs, we only take on businesses we’re sure we can help:
- You already have a product or service that customers really buy — KP3 helps you sell more; it doesn’t find you a product.
- You’re ready to let KP3 lead on the expertise — you review and decide, but you don’t take the work back.
- No banned goods, no pyramid schemes, no scams, and nothing you wouldn’t dare tell your mother about.

Questions you might be asking yourself
Can I use it if I can’t code?
Yes, if you work with an AI agent. The AI reads the docs and quotes the cost first.
Do payments go through KP3?
No. The money goes straight to your account.
When should I have KP3 build it for me?
When you need your own business logic, connections to many old systems, or have nobody to run it.
P.S. You could keep doing everything yourself, try a few more tools, hire a few more people — and hope next month turns out different.
Or you could spend 30 minutes talking with the KP3 team. We’ll show you exactly where you’re losing customers and how to fix it — free, no strings attached. Even if you don’t hire KP3, you leave with a growth map.
