How to vibe codeFactory
Agent-native software development platform

The verdict: can you vibe code Factory?
Keep paying or use existing tools; building an autonomous enterprise-grade software factory with multi-surface clients and dynamic model routing is a massive multi-year engineering undertaking.
Factory is a heavily funded unicorn platform backed by over $220M in venture capital, servicing global enterprises like Nvidia and Adobe with strict compliance, secure sandboxes, and complex model routing. While you can hack together a basic terminal script that calls an LLM and creates a pull request, replicating the full unified experience—spanning a native Electron desktop app, CLI tool, real-time analytics dashboard, dynamic model router with automated failover, and enterprise security controls—is completely out of reach for a solo developer.
Estimated effort: 6+ months of full-time work
What you can't replicate
- Enterprise-grade zero data retention and air-gapped deployment compliance
- Partitioned enterprise inference compute pools and dedicated account management
- Deep security compliance certifications (SOC2, HIPAA, BAA)
- The massive institutional knowledge embedded in their proprietary automation cookbooks

The hard parts of vibe coding Factory
- Building a fault-tolerant model routing layer with automatic provider failover and context preservation
- Executing arbitrary LLM-generated code loops securely without exposing host machines
- Synchronizing agent session states seamlessly across native desktop, web, and CLI clients
- Designing an agent-readiness static analysis engine that accurately scores codebases across technical pillars

Build guide
01Project Scaffolding and Database Schema
Initialize a monorepo containing a Next.js frontend, an Express backend service, and a Turso SQLite database schema to store agent sessions, telemetry logs, and router configurations.
Initialize a TypeScript monorepo with a Next.js web application and an Express backend. Set up Drizzle ORM with Turso SQLite. Create database tables for users, sessions, telemetry_events, and model_routes. Define schemas for tracking token usage, autonomy ratios, and tool execution counts. Ensure strict TypeScript types across all database entities and export validation schemas using Zod.02Factory Router Proxy Layer
Implement a dynamic model routing proxy service that evaluates incoming prompt complexity, selects the optimal LLM provider (Anthropic, OpenAI, or Gemini), and executes automatic fallback if rate limits or errors occur.
Build a model routing service in the Express backend called 'Factory Router'. This service should accept incoming agent requests, inspect prompt characteristics (length, tool requirements, historical complexity), and route them to the cheapest viable model (e.g., MiniMax, Gemini Flash, or Claude Sonnet/Opus). Implement automatic provider failover logic: if a primary model provider returns a rate limit or error, catch the exception and seamlessly retry the request with an alternate fallback model provider. Expose an API endpoint to log routing decisions and calculate aggregated cost savings compared to always using the most expensive model.03Autonomous Agent Loop and Sandbox
Develop the core execution loop where Droids ingest code signals, plan multi-step modifications, execute shell commands in an isolated environment, and generate git diffs.
Implement the core agent execution engine in the backend. Create a module that takes a user task description, initializes a workspace context, and uses the Anthropic API with tool-use capabilities to read files, execute shell commands, and edit code. Build a sandboxed execution wrapper to safely run generated code modifications and execute test suites. Implement an iterative loop where the agent reviews test failures, self-corrects code errors, and outputs a clean git diff.04Electron Desktop Shell and Terminal UI
Package a companion desktop wrapper using Electron along with a terminal UI client to provide multi-surface access for triggering and monitoring Droids.
Create an Electron desktop application shell that loads the Next.js web dashboard and communicates with the backend agent service via WebSockets. Implement a terminal UI (CLI) command runner using Node.js readline or blessed that allows developers to drive Droid sessions directly from their terminal. Ensure session state is synchronized in real-time across the web dashboard, desktop app, and CLI client.05Analytics and Telemetry Dashboard
Build an agent effectiveness and cost analytics dashboard displaying token economics, autonomy ratios, active user metrics, and file operation counts.
Build a comprehensive analytics dashboard in Next.js that visualizes AI engineering metrics. Ingest telemetry data from agent sessions to calculate and display total token consumption grouped by model and user, average autonomy ratios, tool execution counts, and file operation metrics (files created/edited). Include date range filtering and export capabilities for telemetry logs.
