A usable MVP prototype
One core product flow becomes real software you can click, test with users, and show to customers or investors.

What you get in 10 days
AI speed, senior engineering control
AI accelerates the build while senior engineers keep the structure, integrations, and technical risk under control.
Sharp product scope
We focus on the feature path that proves value instead of bloating the MVP with everything on the wishlist.
A foundation for production
If you continue, the code, repository, and accounts are prepared so the full MVP can move forward without starting over.
Momentum within 10 days
You see real product progress early, so business decisions are based on working software instead of proposals and wireframes.
A clear MVP roadmap
At the end of the trial, you get next-step recommendations, a full-build estimate, and the technical risks to watch.
How our vibe coding MVP service works
- 01
Tell us the idea and user
A short call to understand the problem, the audience, and the one flow that matters most.
- 02
We scope the 10-day MVP
We choose a realistic feature path, map the flow, and set trial boundaries so the result is focused and finishable.
- 03
AI accelerates, engineers direct
We vibe-code with AI, then review the important parts: data, auth, integrations, performance, and security.
- 04
You review the result
At the end of the trial, you see a working prototype and choose whether to continue to a full MVP or walk away free.
What's realistic in 10 days (the honest part)
A 10-day free trial is not a promise to build a complete application. What is realistic is one primary flow that proves the problem, the value, and the direction of the product. We build it quickly with vibe coding, then add engineering judgment so the result can be assessed properly by both business and technical stakeholders.
- One core user flow that actually works
- Scope agreed together so it can be finished in 10 days
- A technical foundation that can continue into the full MVP
- An honest estimate for the cost, timeline, and risks of the full build
Why we do this for free
Many software projects start with a thick proposal, then the real risks appear after the budget is already committed. We reverse that process: show a working MVP prototype first, prove how the team works, then discuss the full build. If the fit is not right, you still leave with early validation and a clearer decision.

Ship your startup in weeks, not months
CTO Engine turns an idea into a product that ships, works for real users, and is built clean enough to keep growing, not rebuilt a year later.

Vibe coding & free-trial questions
Is it really free?
Yes. The 10-day trial build is free, with no card and no commitment. You only pay if you choose to continue to the full MVP.
What can you actually build in 10 days?
One core flow of your product, such as onboarding, booking, checkout, a simple dashboard, chatbot, or internal workflow. Not a full app.
Isn't vibe-coded software unreliable or insecure?
On its own, it can be. That is why we do not stop at prompts and AI output: senior engineers review the architecture, data, auth, integrations, and anything that touches real users.
I already have a vibe-coded prototype. Can you help?
Yes. We can audit an AI-built prototype, fix fragile areas, and rebuild only what is needed to make it ready for production.
Do I own what you build?
If you continue with us, the code, repository, and project accounts are prepared as yours. The trial is to prove fit both ways before anyone commits.
What happens after the 10 days?
You get a working prototype and an honest estimate for the full MVP. You decide whether to continue. No pressure, no lock-in.
Will you sign an NDA?
Yes. We're happy to sign an NDA before you share your idea.
Who is this for?
Founders, startups, and businesses that want to test a product idea, internal portal, SaaS, marketplace, or AI workflow before committing a large budget.
