Who it's for

You have an idea.
We build it.

Full Stack is Kleeblack's flagship package. Designed for startups and teams that need to build a complete MVP from scratch: backend, frontend, and quality assured.

Three agents work in parallel — Backend builds the APIs, the Frontend agent builds the UI that consumes them, QA tests both layers. The Senior orchestrates everything and reviews every delivery before it reaches your hands.

🚀

Complete MVP in weeks

From requirements to a working product in production in record time. No waiting months for team onboarding.

🔗

Integrated Backend + Frontend

Agents share the same architecture context. No desync between API and UI — the Senior guarantees cohesion.

End-to-end tests included

The QA Agent writes unit, integration, and E2E tests that cover the complete user flow. Minimum 80% coverage guaranteed.
