Overview

Coletix AI is a DEVSELL-built AI platform designed to support prompt-based full-stack software development, autonomous AI agents, application planning, cloud deployment direction and advanced software orchestration.

Agent orchestration layer, prompt & planning pipeline, code generation engine, workspace UI on React/Tailwind, backend services in Python and Node.js, and cloud-ready deployment tooling.
