Your Unfair Advantage for Growing Brand Visibility

The verdict: can you vibe code Semrush?
Build a personal wrapper or local rank-tracker for your own domains, but you cannot clone Semrush because its core value lives inside petabyte-scale proprietary databases and web-crawler infrastructure.
Semrush is a data enterprise masquerading as a web app. While an AI coding agent can spin up a polished Next.js dashboard with charts, auth, and database models in an afternoon, an empty database makes the application completely useless. You cannot replicate a 28-billion keyword index, 43-trillion backlink database, and global clickstream panel as a solo developer without spending millions of dollars on data acquisition and distributed scraping infrastructure. Building a personal clone means scaling down to tracking your own custom keywords using direct Google Search APIs and local cron jobs.
Estimated effort: 6+ months of full-time work for a crippled subset, forever for the full platform
What you can't replicate
- 28B+ keyword database across 142 regional search databases
- 43T+ backlink index updated continuously
- Global clickstream behavioral panel of 200M+ users for traffic estimation
- Enterprise-scale distributed web crawler network bypassing bot walls

Build guide
01Project Scaffolding & Design System Setup
Initialize the Next.js application with Tailwind CSS, TypeScript, and Shadcn/ui components configured for a dark-themed analytics dashboard layout.
Scaffold a new Next.js 16 application with TypeScript, Tailwind CSS v4, and App Router. Set up a professional enterprise SaaS dashboard layout styled similarly to Semrush, featuring a collapsible sidebar navigation, top header with user profile dropdown, and a main content viewport with a dark/light theme toggle. Install Lucide React icons and configure Shadcn/ui foundational components (card, table, dialog, dropdown-menu, tabs).02Database Schema & Authentication
Configure Turso SQLite database with Drizzle ORM and implement local user authentication using better-auth.
Configure Drizzle ORM to connect to Turso SQLite using the HTTP client driver. Create database schemas for users, projects (tracking domain URLs), tracked_keywords (domain, keyword, target region, search volume, difficulty, current rank), and rank_history (date, keyword_id, position). Implement better-auth for secure email/password authentication with session management and protecting dashboard routes.03Domain Overview & Keyword Research Subset
Build the Domain Overview dashboard view and a mock Keyword Magic Tool interface that queries external search or AI fallback data for personal domain analysis.
Build a Domain Overview page where users input a target domain URL. Create backend API endpoints that fetch basic site metrics (organic traffic estimate, keyword count, backlink count) using web scrapers or Firecrawl API fallback. Implement a Keyword Magic Tool interface with a searchable table displaying keyword ideas, search volume, keyword difficulty score, and intent badges, backed by your Turso SQLite database.04Position Tracking & Rank History Charts
Implement daily position tracking charts using Recharts to visualize keyword rank fluctuations over time.
Create a Position Tracking module with a form to add custom keywords for user projects. Build interactive time-series line charts using Recharts that display daily rank positions (1 to 100) over 7, 30, and 90-day periods. Implement background cron triggers or manual update buttons that simulate or fetch rank updates and store historical data points in the rank_history table.05AI Visibility & Brand Sentiment Tracker
Integrate LLM prompt testing to track how AI search engines cite and mention brand names.
Build an AI Brand Sentiment tracking module. Create an API route utilizing the Vercel AI SDK and Anthropic/OpenAI APIs to programmatically query live models with custom user prompts (e.g., 'What are the top software tools for X?'). Parse the LLM responses to determine if the user's configured brand domain is cited, calculate brand visibility share of voice, and display sentiment breakdown charts on the dashboard.
