How Metacloud Builds a B2B SaaS in 15 Minutes

You type a description. Fifteen minutes later, there's a working B2B SaaS at its own URL, with a database, a UI, and source code you own. Here's exactly how that happens.

1

You Describe What You Need

No wireframes. No technical specs. Just plain English.

"Create a CRM for a small sales team. Track contacts, companies, deals with pipeline stages, and activity log. Dashboard showing deal values by stage."

That's the entire input. Metacloud takes it from here.

2

AI Breaks It Down

Your description goes to an AI that understands web applications. It doesn't just generate code — it plans. The AI decomposes your idea into concrete, atomic tasks:

  • Database models (contacts, companies, deals, activities)
  • Routes and views for each feature
  • Dashboard with aggregations
  • Navigation and layout

Each task is small enough to implement correctly in one pass. This is the same strategy experienced developers use: break the problem down first, code later.

3

Code Generation

Each task becomes a code generation job. The AI writes real Python (Flask) with real HTML templates, real SQLite queries, real CSS. Not pseudo-code. Not a prototype. Production-ready code.

The generated code follows conventions:

  • Flask application factory pattern
  • SQLite database with proper schema
  • Jinja2 templates with responsive CSS
  • Error handling and input validation
4

AI Code Review

Every piece of generated code goes through an AI code review — the same model wearing a reviewer hat. It checks for:

  • Does this actually implement what was asked?
  • Are there security issues? SQL injection? XSS?
  • Does it integrate with the existing code?
  • Are there obvious bugs?

If the review finds issues, the code goes back for revision. Up to three rounds. If it still doesn't pass, it's flagged for human review.

5

Merge & Deploy

Approved code gets merged into the project's git repository. Then Metacloud:

  1. Creates a Python virtual environment
  2. Installs dependencies
  3. Runs the database migrations
  4. Starts the application on an isolated port
  5. Maps it to your-app.metacloud.io

Your app is live. With a real URL. You can share it, test it, show it to users.

6

It's Yours

Every line of source code is in a git repo you can clone. Want to modify it? Clone the repo and go. Want to host it yourself? Download and deploy anywhere Python runs. There's no lock-in, no proprietary runtime, no magic you can't inspect.

What You Get

In about 15 minutes, from a text description:

  • ✅ A working B2B SaaS product

  • ✅ Deployed at your-app.metacloud.io
  • ✅ SQLite database with real schema
  • ✅ Free to try without signup, signup to save data
  • ✅ Git repository with full source code — no lock-in
