AI Tool Intelligence — The Stackradar Engineering Book (PRO)

AI Tool Intelligence — The Stackradar Engineering Book The complete engineering playbook behind a 7/24 autonomous AI tool research engine. How a solo indie maker built, scaled, and ran it at $13/month compute. 📕 PRO Edition · 16,000+ words · Full architecture deep dive 💰 $19 standalone · or $14.50 in MEGA Pack with code MEGA50 🔄 7-day no-questions refund 🎯 What this book is NOT This isn't another "Best AI tools 2026" generic listicle. This isn't a "10 AI tutorials" beginner pack. This is the actual engineering playbook behind Stackradar — a working autonomous research engine that I run in production, that scores 738 AI tools 0-10 daily, that costs $13/month to operate. ↑ Where Stackradar was built. Multiple monitors, Claude API, Playwright, and a lot of coffee. 📚 Inside the Book Part Topic What you learn 1 Architecture decisions SQLite vs Postgres trade-offs · Node vs Python reasoning · zero-ops mindset 2 Scout & Analyst pipeline Discovery layer · queueing · error recovery · rate limit handling 3 Claude Sonnet 4.6 extraction Prompt caching strategy that cut costs 80% · structured output validation 4 Playwright automation Screenshot capture · anti-bot handling · headless edge cases 5 Quality scoring methodology The actual 0-10 rubric · written reasoning template · ranking weights 6 SQLite production schema Schema design · migrations · queries that scale to thousands of entries 7 Single-file HTML dashboard Why I rejected React · offline-first patterns · embed JSON inline 8 Cron orchestration Daily refresh logic · monitoring · what breaks at 3am 🔧 The Actual Stack SQLite — single-file portable database, zero ops overhead Node.js + TypeScript — orchestration layer with p-queue rate limiting Claude Sonnet 4.6 — extraction layer with prompt caching (80% cost cut) Playwright — headless browser for screenshots + DOM extraction node-cron — daily refresh trigger Brave Search API — discovery layer (1 req/sec rate limited) Total monthly compute cost: ~$13. Yes, really. 📊 What You'll Build After Reading A 7/24 research engine for any domain — SaaS tools, e-commerce, content trends A scoring methodology with written reasoning (not just star ratings) An offline-first dashboard that scales to thousands of entries A cost-controlled Claude pipeline with prompt caching A production cron architecture that doesn't break at 3am If you've ever wondered "how does someone actually run a daily AI scraping operation alone?" — this is that. 🎯 Who This Is For Indie AI engineers — building data products with Claude / GPT SaaS founders — researching tools, competitors, trends programmatically Solo developers — who want production patterns, not toy examples Technical readers — interested in real architecture decisions, not best-practice lists 💰 Pricing Option Price Code Engineering Book PRO — standalone $19 — MEGA Pack (8 products incl. this) $29 — MEGA Pack with launch discount $14.50 MEGA50 7-day no-questions refund.
