In good company
Watch your idea become a working product
A real PRD, real code, a live URL — watch us run the whole product process, step by step.
What do you want to build?
A marketplace where local chefs can sell home-cooked meals to nearby customers, with real-time order tracking, ratings, and student-courier delivery.

Most people vibe code.Almost nobody ships.
That's because generating code is the easy part. Making it actually work — correct, scalable, ready for real users — that's the hard part. That's where we come in.
Idea → Live App in 4 Steps
Four simple steps from a rough idea to something real.
Describe your idea
Type what you want to build. Upload docs, reference apps, or just a sentence.
Approve the plan
Lumexa drafts your PRD, use cases, and acceptance criteria. You review and approve — that's the definition of done.
Watch it build
Full-stack code — React frontend, Express backend, real database — generated and tested in front of you.
Go live
Your app deploys to its own database and URL. Connect a custom domain when you're ready.
Everything a product team does — built in
Your definition of done, built in
Every build is planned against a PRD with use cases, acceptance criteria, and API contracts — then checked against them. Nothing falls through the cracks.
A real stack you own
React frontend, Express backend, Prisma + Postgres — on its own infrastructure, exportable to your GitHub. Not a prototype in someone's sandbox.
One-Click Deploy
Your app goes live on its own database and URL. Connect a custom domain when you're ready.
Not just another AI code generator
Most tools stop at code. Lumexa runs the product workflow that makes what you ship actually production-ready.
Hiring a dev team
- 4–6 weeks to a first version
- High upfront cost
- Full product thinking — but all manual
- Slow, expensive iteration
- You own the code
- You pay day rates whether it works or not
Other AI builders
- A demo in minutes — then hours babysitting prompts
- Low cost
- Generates code — but you scope it
- No definition of done — "working" is a feeling
- Code you have to debug yourself
- Every retry burns credits — you pay for their failures
Lumexa
- A live, tested app within the hour — unattended
- Low cost — free to start
- Your approved PRD is the definition of done
- Acceptance criteria & traceability built in
- Production-ready output you own 100%
- Humans stand behind every build
- Failed builds and fixes cost you nothing
The only AI builder with humans behind it
Your approved plan is our promise. If what we ship doesn't match it, we'll fix it — simple as that.
Build Assurance
If your deployed app doesn't match the acceptance criteria in your PRD, our team fixes it — no extra credits, no debugging on your own.
Expert Sessions
Book an hour with a Lumexa engineer for integrations, data migration, or a pre-launch review.
The guarantee covers conformance to your approved PRD — a real, checkable standard, not a feeling.
Built for whoever has the idea
Whether you're shipping a startup, a feature, or a client project — Lumexa adapts to you.

Lumexa Frequently Asked Questions (FAQ)
Everything you need to know about building, owning, and shipping with Lumexa.
Not at all.
You do not need any coding experience to use Lumexa. In fact, helping non-technical founders build software is one of the primary reasons Lumexa was created.
Whether you have zero technical knowledge or years of experience, Lumexa is designed to help you bring your ideas to life.
It depends on what you're building — most builds finish well within the hour.
You don't need to watch it happen: kick off the build, close the tab, and we'll email you the moment your app is live.
For perspective: a typical agency quote for the same scope is 4–6 weeks.
Your approved PRD is the definition of done.
When you approve your Product Requirements Document, its acceptance criteria become the standard your app is built and tested against. If your deployed app doesn't meet those criteria, our team fixes it at no extra cost — that's Build Assurance, included in every paid plan.
The guarantee covers conformance to the PRD you approved. New ideas and scope changes are easy to add through chat iterations, but they become part of a new plan rather than the original guarantee.
Need hands-on help beyond that? You can book an Expert Session with a Lumexa engineer.
The free plan allows you to:
- Create your first project
- Build a PRD (Product Requirements Document)
- Upload documents and requirements
- Generate a working application
However, project editing is only available on paid plans.
Free plan limitations
- Projects expire after 14 days
- Expired projects become inaccessible
- Each account can create 1 free project
After your free project, a paid subscription is required to continue creating projects.
You do.
Every project built with Lumexa is deployed to its own dedicated infrastructure and database environment. Your project data is not shared with other users and is not accessible by other customers.
Your application, your data, and your business remain yours.
Yes.
Free projects are hosted under a Lumexa subdomain — for example, yourproject.lumexa.ai. Paid plans allow you to connect your own custom domain.
As a bonus, Lumexa includes your first year of domain registration at no additional cost.
