Lotus / Code Horizon, AI Software Platform
Describe the app you want. Code Horizon takes it through idea, MVP, user flows and architecture to generated code running on a live preview URL you can publish to GitHub.
- Prompt to running app: core idea → MVP features → user flows → architecture → code
- Live hosted preview of every build, with version history and rollback
- Architecture and cost estimate produced before any code is generated
Project Overview
An AI platform that turns a written idea into shipped software. A step pipeline walks the user from core idea to MVP feature set, user flows, system architecture and a cost estimate, then generates the code and builds it to a hosted preview URL — versioned, so any build can be rolled back. Finished projects leave as a source download, a .docx specification, or a push straight to the user’s GitHub. Behind it sits the commercial machinery most AI products skip: a credit engine that classifies each job’s complexity and prices it accordingly, plan tiers, bonus-credit expiry, abuse guards and an admin console.
Requirements & Features
- Prompt to running app: core idea → MVP features → user flows → architecture → code
- Live hosted preview of every build, with version history and rollback
- Architecture and cost estimate produced before any code is generated
- Publish three ways: download the source, export the docs as .docx, or push to GitHub
- Multi-model routing across GPT, Claude and DeepSeek, streamed token by token
- Credit engine that prices each job by AI-classified complexity, not a flat rate
- Admin dashboard: analytics, user credit management, abuse guards
What I Delivered
Flutter Web front end, Node backend with 14 route modules and 15 data models, the AI step pipeline and preview build service, background workers, and the full credit, billing and admin stack.

The engineering story
The Hardest Feature in an AI App Builder Is Saying 'Done'Generating the code is the easy part. Building Code Horizon — an AI platform that takes a prompt to a live URL — the hard problem was knowing when a build is actually finished. A 13-state status machine, why we chose polling over streaming, and regenerating only what changed.Read the article · 9 min →Want something like Lotus / Code Horizon?
