The verdict: can you vibe code MarketMaster?
Build a single-channel version with Claude Code in 2-3 weeks, but expect friction integrating 8 different social network APIs and the dual-model validation loop.
Replicating the core workflow—scraping a URL, generating a brand kit, prompting asset generation, and running a dual-model validator—is entirely feasible with a modern TypeScript stack and AI coding tools. However, integrating the live publishing graph across eight different social platforms (LinkedIn, X, Instagram, TikTok, YouTube, Facebook, Pinterest, Threads) introduces massive OAuth maintenance debt and rate-limit edge cases that will drain your weekends.
Estimated effort: 2-3 weeks of part-time development

Build guide
01Project Scaffolding and Database Schema
Initialize a Next.js project with Tailwind CSS and shadcn/ui. Set up Turso for SQLite storage and configure better-auth for user authentication.
Create a new Next.js project using App Router, Tailwind CSS, and TypeScript. Install better-auth configured with Turso (libSQL) as the database adapter. Create database schema migrations for Users, BrandKits, Campaigns, CampaignAssets, and PublishLogs tables. Add basic user session protection middleware for dashboard routes.02Website Scraping and Brand Kit Extraction
Implement the source research step by scraping a target URL, extracting text content, logos, and color palettes, and structuring them into a reusable Brand Kit.
Build an API route that accepts a target website URL. Use Firecrawl or native fetch/cheerio to scrape the homepage, pricing, and product pages. Pass the extracted raw text to OpenAI GPT-4o with a structured JSON output prompt to extract audience description, offer details, differentiation points, proof items, color hex codes, and logo image URLs. Save these results into the BrandKits table linked to the user.03Campaign Briefing and Ad Pattern Selection
Build the campaign goal selector and verified ad structure pattern selector UI and database mapper.
Create a multi-step campaign creation wizard UI in Next.js. Step 1: Input target URL and display extracted Brand Kit for user review and edits. Step 2: Select campaign goal (lead gen, product launch, awareness) and choose from a predefined list of 5 verified original-ad pattern structures (e.g., Problem-Agitate-Solve, Before-After-Bridge). Save brief state in local workflow state before triggering asset generation.04Multi-Format Asset Generation Pipeline
Connect AI text and media models to generate static ad copy, carousel slides, short script ideas, and campaign emails based on the approved Brand Kit and ad pattern.
Build a campaign generation background action that takes the approved Brand Kit and Ad Pattern. Call Anthropic Claude Sonnet to generate platform-specific social posts (LinkedIn, X, Instagram), a 5-slide carousel text structure, and a campaign email. Simultaneously call Fal.ai API for static ad image generation using Flux Schnell, incorporating brand colors. Store all generated assets in the CampaignAssets table with status 'pending_review'.05Dual-Model Evidence Engine Verification
Implement the compliance review step where two independent AI models review generated assets for claim safety, hook strength, and AI slop.
Implement the Evidence Engine validation loop. When assets are generated, send them in parallel to two evaluation prompts: one evaluated by Anthropic Claude Sonnet and one by OpenAI GPT-4o. Each model must output a strict JSON payload with boolean approval, list of flagged slop phrases, and claim safety score against the source Brand Kit evidence. Require both models to return approved: true before unlocking the publication UI. Render clear audit feedback badges on each asset card in the dashboard.06Publishing, Scheduling, and History Tracking
Build external API connectors and UI to schedule or immediately post verified assets to connected social channels.
Build social platform publishing integrations for LinkedIn and X (Twitter) using official OAuth2 endpoints and API v2 posting routes. Create a Publish/Schedule dashboard view that lists approved campaign assets, displays scheduling selectors, and tracks live provider post IDs, permalinks, and sanitized failure logs in the PublishLogs table.
