# How to Vibe Code Your Own Seobility (and Stop Paying for It) > Online SEO Software & Tools For Better Rankings - Site: https://seobility.net - Category: SEO & Marketing SaaS - Platforms: Web app - Verdict: **Serious undertaking** (45/100 vibecodeable) - Estimated effort: 4-6 weeks of part-time development and infrastructure tuning ## Verdict You can build a personal dashboard wrapper with a basic cheerio/playwright scraper, but scaling a multi-page crawler and reliable SERP rank tracker requires heavy backend engineering. While an AI coding agent can scaffold the Next.js frontend, database schemas, and simple Cheerio-based scrapers in hours, the real engineering roadblocks emerge at scale. Running a recursive web crawler that correctly executes client-side single-page applications without hitting Cloudflare blocks, managing proxy rotation for 90+ country rank tracking, and processing large text corpora for TF*IDF optimization involve complex background worker pipelines, queues, and persistent storage that demand constant debugging. ### What you can't replicate - 15-year historical backlink index and proprietary link authority graphs - Massive distributed proxy infrastructure required for global daily SERP rank tracking without getting banned ## What it does All-in-one SEO and AEO software suite covering technical website audits, ranking monitoring, backlink tracking, keyword research, and TF*IDF content optimization. ### Core features - Headless web crawler with JS rendering (React/Vue/Angular) to evaluate 300+ SEO parameters - Daily SERP ranking monitoring across multiple countries and local regions - Backlink profile tracker monitoring new, lost, and broken incoming links - SEO competitor analysis benchmarking rankings and keyword overlap - TF*IDF content optimization analyzer for semantic keyword density and content gaps - 24/7 server uptime monitoring with automated email notifications - White-label PDF report generator for audits and tracking summaries ## The business ### Pricing - Basic: Free — For small personal sites with basic crawl and keyword tracking needs. - Premium: €49.90 / month — For growing businesses and professional webmasters. - Agency: €179.90 / month — For SEO agencies requiring multi-project management and white-label reporting. ### Funding $0 raised. - Bootstrapped Investors: Self-funded, saas.group (Acquired in 2022) Founded 2011. Team size: 11-20. ## The hard parts - Massive concurrent web crawling without triggering WAF blocks (Cloudflare/Akamai) or running out of memory during client-side SPA rendering - Reliable SERP rank scraping across 90+ countries with proxy rotation and CAPTCHA evasion - Building a performant TF*IDF text corpus processing engine that extracts top-ranking competitor terms - Storing and querying millions of historical ranking time-series data points and backlink graphs efficiently ## How to vibe code Seobility ### Prerequisites - Node.js (free): Runtime environment for TypeScript, Next.js, and backend scraping scripts. - GitHub (free): Code repository and deployment hook for hosting providers. ### Recommended AI tools - Claude Code: Best-in-class multi-file agentic coding tool for scaffolding complex backend crawl loops and React components. - Cursor: Ideal IDE fork for fine-tuning UI dashboards, charts, and audit table components. ### Stack - Frontend: Next.js with Tailwind CSS and Recharts for ranking charts - Backend: Next.js API routes with Playwright and Cheerio for crawling/scraping - Database: Neon (Serverless Postgres for storing audits, rankings, and historical snapshots) - Auth: better-auth (Self-hosted authentication for single or multi-user access) - Payments: None (Personal-use clone skips billing entirely) - Other: Trigger.dev for managing long-running background crawler jobs, Resend for sending uptime monitoring email alerts ### Hosting - Vercel (Hosting the Next.js frontend and serverless API dashboard): $0/mo (Hobby Tier) - Railway (Hosting persistent background worker containers for heavy web crawling and cron scrapers): ~$5/mo ### Build guide 1. **Project Scaffolding & Database Schema** — Initialize a Next.js project with Tailwind CSS, configure Neon Serverless Postgres via Drizzle ORM, and set up better-auth. ``` Create a new Next.js project with TypeScript and Tailwind CSS. Set up Drizzle ORM connected to Neon Postgres with the following tables: 'projects' (id, user_id, url, created_at), 'audits' (id, project_id, status, issues_json, score, created_at), 'rankings' (id, project_id, keyword, rank, search_engine, tracked_date), and 'backlinks' (id, project_id, source_url, target_url, anchor_text, link_status, domain_authority). Implement better-auth for user authentication with email and password. Ensure all database migration files and client utilities are fully typed and structured. ``` 2. **Website Audit & Crawler Engine** — Build a recursive web crawler using Cheerio and Playwright to analyze pages for metadata, broken links, and SEO factors. ``` Build a robust web crawler module in TypeScript using Cheerio for static HTML parsing and Playwright for JavaScript rendering fallback. The crawler must ingest a target URL, respect robots.txt rules, discover internal links recursively up to a configurable page limit (e.g., 1,000 pages), and evaluate 300+ parameters: missing title tags, missing meta descriptions, H1 presence, broken internal/external HTTP links, image alt attributes, and response load times. Store the raw audit results and aggregated checklist issues as a JSON payload in the 'audits' table linked to the project ID. Provide a server action or API route to trigger crawls asynchronously. ``` 3. **Ranking Monitoring & SERP Scraper** — Implement keyword tracking and SERP position lookup logic. ``` Create a ranking monitoring service that takes a list of keywords associated with a project and checks their current Google search ranking positions. Implement a modular fetcher using proxy rotation support to query search results, extract matching domain listings, and record daily positions into the 'rankings' table. Build a background cron job using Trigger.dev to automate daily rank checks across configured projects. Include error handling for CAPTCHAs and temporary rate limits with exponential backoff. ``` 4. **Backlink & Competitor Analysis Modules** — Build tracking interfaces and mock/live ingestion for backlink profiles and competitor benchmark comparisons. ``` Develop a backlink monitoring and competitor analysis backend service. Create database structures and API endpoints to log incoming backlink profiles, track new or lost links, and compute basic link quality metrics. Build a competitor analysis module that allows users to input up to 5 competitor domains per project, fetching their ranking overlap and keyword gaps using public search endpoints or cached SERP data. Expose these metrics via structured API routes for frontend dashboards. ``` 5. **TF*IDF Content Optimization Tool** — Implement a text analysis engine that computes term frequencies and content relevance gaps against competing top pages. ``` Build a TF*IDF content optimization tool module. The backend should accept a target keyword and target page content, fetch top 10 ranking competitor pages for that keyword, extract and tokenize their body text, calculate Term Frequency-Inverse Document Frequency (TF*IDF) weights across terms, and compare them against the user's draft content. Return a semantic gap analysis list highlighting underused or overused terms, keyword density scores, and content structure recommendations. Create an accompanying React text editor view showing real-time term suggestions. ``` 6. **Uptime Monitoring & Alerting** — Set up a 24/7 cron-based server availability checker with Resend email alerts. ``` Implement an uptime monitoring worker that runs every 5 minutes across all project URLs using cron triggers. The worker must perform HTTP HEAD/GET requests, measure response latency, check for 2xx/3xx status codes, and record downtime incidents in a new 'uptime_logs' table. Integrate the Resend API to send immediate email notifications to the project owner when a website goes down or recovers. Build an uptime status dashboard component showing 24-hour availability graphs. ``` 7. **Dashboard UI & White-Label Reporting** — Assemble the cohesive dashboard interface with Recharts analytics and PDF export capabilities. ``` Build a comprehensive Next.js frontend dashboard with Tailwind CSS mimicking professional SEO platforms. Create views for: 1) Overview summary with audit health score rings, 2) Website Audit prioritized to-do list table with issue filters, 3) Ranking Monitoring line charts using Recharts showing position trends over time, 4) Backlink profile list, and 5) TF*IDF content editor. Implement a client-side PDF export utility (using jsPDF or html2pdf) that generates a clean, white-labeled audit report featuring custom branding headers for agency use. ``` ### Cost vs paying **Starting costs (one-time):** - Custom domain (optional): $12 one-time - Proxy service for SERP tracking: $10 one-time - Total: ~$22 one-time **Ongoing costs (monthly):** - Railway background worker hosting: $5/mo - Proxy pool usage: $10/mo - Total: ~$15/mo - Paying for the SaaS instead: €49.90/mo (~$54/mo) - Build time: 40-60 hours - AI tool credits: $20 (Claude Pro) - Break-even: 1 month ## Sources - [Seobility Official Website](https://www.seobility.net) - [GetLatka - Seobility.net Revenue and Growth Profile](https://getlatka.com/companies/seobility.net) - [saas.group - Acquisition Announcement Context](https://saas.group)
