How We Built 120+ Websites in One Week Using AI (And You Can Too)

In February 2026, one person built and deployed over 120 live, functional websites in seven days. Not placeholder pages. Not templates with Lorem Ipsum. Fully designed, SEO-optimized, content-rich websites with custom tools, blog posts, analytics, and monetization — all live on custom domains.

This is not a hypothetical. This is what happened at SpunkArt. And the playbook we used is something anyone with a laptop and an AI subscription can replicate.

This article breaks down exactly how we did it: the tools, the process, the tech stack, the strategy, and the lessons learned. If you have ever wanted to build a web empire but thought it would take years and a team of developers, keep reading. The rules have changed.

Why Build 120 Websites?

The question everyone asks first: why would anyone need 120 websites? The answer is simple: diversification and surface area.

In the attention economy, distribution is everything. One website competes in one niche for one audience. A network of 120+ websites competes across dozens of niches, catches hundreds of different search queries, and creates a web of cross-linked properties that amplifies every piece of content across the entire network.

Here is the strategic thinking behind it:

"The internet rewards breadth of presence. One site is a business. A hundred sites is an empire. AI made the second option as accessible as the first used to be."

The Tech Stack

The entire empire runs on a deliberately simple, zero-cost tech stack. Complexity is the enemy of speed, and every additional dependency is a potential point of failure. Here is what powers everything:

Claude Code (Anthropic) — The Engine

Role: Primary code generation, content writing, site architecture, debugging, deployment automation. Claude Code is not an autocomplete tool — it is an autonomous coding agent that reads your entire codebase, plans implementations, writes code across multiple files, runs tests, and deploys. It was the single tool that made this scale possible.

Why Claude Code specifically: Claude Opus 4.6 has the deepest understanding of codebases we have tested. It maintains context across hundreds of files, follows instructions precisely, and produces production-quality code on the first attempt far more often than alternatives. The terminal-native workflow means no context-switching between an IDE and an AI chat window.

GitHub Pages — Free Hosting

Role: Hosting every site for free. GitHub Pages serves static sites from GitHub repositories with custom domain support, HTTPS, and global CDN. Zero hosting cost. Zero DevOps. Push to main branch, site is live in seconds.

Why it works: Static HTML sites are the fastest possible web architecture. No server to configure, no database to manage, no containers to orchestrate. The entire deployment pipeline is git push.

Vanilla HTML, CSS, JavaScript — No Frameworks

Role: Every site is built with plain HTML, CSS, and JavaScript. No React. No Next.js. No build step. No npm install. No node_modules. No webpack. No Tailwind compilation step. Just files that browsers understand natively.

Why no frameworks: Frameworks add complexity, build steps, dependencies, and maintenance burden. When you are building 120 sites, every minute spent on toolchain setup is multiplied 120 times. Vanilla code loads faster, deploys instantly, and never breaks because a dependency updated.

Custom Domain Network

Role: Each major property has its own domain configured with DNS pointing to GitHub Pages. Domains include spunk.codes, spunk.bet, spunkart.com, and the entire predict network (predict.horse, predict.codes, predict.mom, predict.gay, predict.beauty, predict.christmas, and 10 more).

Firebase (Predict Network Only)

Role: Real-time database for the 16 prediction market sites. Firebase Realtime Database stores predictions, votes, and leaderboard data. The free Spark plan is more than sufficient for current traffic. Everything else in the network is pure static HTML.

Total Monthly Hosting Cost: $0

GitHub Pages is free. Firebase Spark plan is free. DNS costs are annual domain registration only. The entire 120+ site network runs on zero monthly hosting costs. That is not a typo. GitHub Pages is the most underrated hosting platform on the internet.

The Process: Day by Day

Here is approximately how the week unfolded. Each day built on the systems and templates established the day before, creating accelerating momentum.

Day 1: Foundation and Architecture

Established the core design system: dark theme, orange accent (#ff5f1f), responsive layouts, component patterns (tool-cards, CTA boxes, tip boxes). Created the first 5 tool pages for spunk.codes to validate the template. Set up GitHub Pages with custom domain. Deployed the first live site.

Sites live: ~5 pages on spunk.codes

Day 2: Tool Explosion

With the template proven, used Claude Code to generate tools at scale. Each tool follows the same pattern: standalone HTML page, dark theme, full functionality in vanilla JavaScript, SEO meta tags, analytics, cross-promotion links. Built 30+ tools in a single day including the JSON formatter, color palette generator, password generator, invoice generator, and SEO checklist.

Key insight: Once you have a proven template, each additional page is mostly new content with the same structure. Claude Code generates a complete, functional tool page in 2-5 minutes.

Sites live: ~40 pages on spunk.codes

Day 3: Content and Blog Posts

Generated the first batch of blog posts: vibe coding guides, tool comparison articles, "50 best" lists. Each post is 3,000-6,000 words with internal links to our tools, CTAs for ebooks, and cross-links to other network sites. Established the blog template with table of contents, styled sections, and mobile-responsive layout.

Sites live: ~70 pages across spunk.codes

Day 4: The Predict Network

Built the prediction market platform: a generator script (Python) that creates customized prediction sites for different niches. Each site connects to the same Firebase backend but has unique branding, content categories, and domain. Deployed 16 prediction sites in a single day using the generator.

Sites live: 16 predict sites + ~80 pages on spunk.codes

Day 5: Spunk.Bet Casino

Built the crypto casino platform: 10 games (Dice, Crash, Mines, Plinko, Coinflip, Slots, Keno, Hilo, Wheel, Blackjack), SPUNK token integration, faucet system, referral program, and prize display. Each game was built as a standalone module with provably fair mechanics.

Key insight: Claude Code built each casino game in 15-30 minutes including animations, sound effects, and game logic. Manually, each game would have taken 2-3 days.

Sites live: spunk.bet + 16 predict sites + ~90 pages on spunk.codes

Day 6: Ebooks, Store, and Monetization

Generated 15+ ebooks covering AI automation, vibe coding, prompt engineering, side hustles, SEO, email marketing, and more. Built the ebook store with checkout flow. Added affiliate tracking, email capture, and cross-promotion widgets across all sites. Revenue infrastructure in place.

Sites live: 110+ pages total across all properties

Day 7: Polish, SEO, and Launch

Final day: added structured data (JSON-LD) to every page, verified all internal links, optimized meta descriptions, added social sharing images, compressed all assets, and verified mobile responsiveness across every site. Submitted sitemaps to Google Search Console. The network was live.

Sites live: 120+ pages across spunk.codes, spunk.bet, spunkart.com, and 16 predict network sites

See the Results

Every site we built is live right now. 200+ free tools, a crypto casino, 16 prediction markets, and an ebook store. All built in one week. All still running.

What We Built (Categories)

The 120+ sites fall into distinct categories, each serving a strategic purpose:

SpunkArt Tool Hub (spunk.codes) — 200+ Pages

The flagship property. 200+ free tools across categories: developer tools (JSON formatter, regex tester, API tester, code playground), design tools (color palette, gradient generator, image compressor), SEO tools (meta generator, schema generator, sitemap builder), business tools (invoice generator, business plan generator, contract generator), social media tools (post generators, hashtag generators, analytics), and AI tools (writing assistant, image prompt builder, product description writer).

Each tool is a standalone HTML page with full functionality, zero dependencies, and no signup requirement.

Predict Network — 16 Sites

16 prediction market sites, each on a unique domain and targeting a different niche:

All 16 sites are generated from a single Python script that customizes branding, categories, and content for each domain while sharing the same Firebase backend.

Spunk.Bet Casino

A free-to-play crypto casino with 10 games, a SPUNK token faucet, referral system, and ordinal NFT prizes. Built entirely with vanilla JavaScript — no backend servers, no databases, everything runs client-side with blockchain verification.

SpunkArt.com — Hub Site

The central brand hub connecting everything: digital art, NFT collections, the WhoAmI ordinal collection, and links to every property in the network.

Blog Content — 80+ Articles

Long-form SEO content across all sites: "50 best" lists, how-to guides, tool comparisons, industry analysis, and strategy pieces. Each article is 2,500-6,000 words with internal links, CTAs, and structured data.

How Claude Code Changed Everything

Let me be direct: this project would have been impossible without Claude Code. Not "slower." Not "harder." Impossible for a single person in a single week. Here is why.

Speed of Generation

Claude Code generates a complete, functional tool page (HTML + CSS + JavaScript + SEO + analytics) in 2-5 minutes. A human developer writing the same page from scratch would take 2-4 hours. That is a 30-60x speed multiplier. Over 200+ pages, the time savings measured in hundreds of hours.

Codebase Awareness

Claude Code reads your entire codebase. When you say "build a new tool page that follows the same pattern as the existing tools," it examines the existing code, matches the design patterns, uses the same CSS classes, follows the same SEO structure, and maintains consistency automatically. No style guide document needed — the codebase IS the style guide.

Multi-File Operations

Building a new site section often requires changes across multiple files: the new page, the navigation, the sitemap, the blog index, cross-promotion links. Claude Code handles all of these in a single operation, maintaining consistency across the entire codebase.

Debugging at Speed

When something breaks (and things always break), Claude Code reads the error, reads the relevant code, identifies the root cause, and fixes it. What would be a 30-minute debugging session becomes a 30-second fix. When you are deploying 120+ sites, fast debugging is not optional — it is existential.

AI Is the Engine, Not the Driver

A critical distinction: Claude Code generated the code, but a human directed every decision. Which tools to build, which niches to target, how to structure monetization, what the brand should feel like, which content to prioritize. AI is a 100x multiplier on human judgment. Without good judgment to multiply, it just produces 100x mediocrity. The strategy, taste, and direction were entirely human.

The Vibe Coding Approach

We call this approach vibe coding: describe what you want in natural language and let AI generate the implementation. It is the opposite of traditional software engineering where you plan meticulously, write specs, then implement line by line.

Vibe coding works because:

  1. Speed over perfection. A working tool with 90% polish, shipped today, beats a perfect tool shipped next month. You can always iterate. You cannot always get back lost time.
  2. Natural language is the new programming language. Describing what you want ("build a password generator that supports uppercase, lowercase, numbers, symbols, and custom length") is faster and more intuitive than writing the code manually. The AI translates intent into implementation.
  3. Iteration is instant. "Make the buttons bigger." "Add a dark mode." "Include a copy-to-clipboard button." Each refinement takes seconds, not hours. The feedback loop between idea and implementation shrinks to near zero.
  4. Technical debt is manageable. When each page is a standalone HTML file with no dependencies, there is no complex dependency graph to manage. If a page needs updating, update it independently. No cascading failures.

Monetization Strategy

Building 120 sites is meaningless if they do not generate revenue. Here is how the network is monetized:

1. Ebook Sales (spunk.codes/store)

Digital products on AI automation, vibe coding, prompt engineering, SEO, email marketing, side hustles, and more. Priced at $9-29, sold through Gumroad with zero marginal cost. Content written with AI, packaged and sold at scale.

2. Affiliate Marketing

Tool recommendation articles and blog posts include affiliate links to software, hosting, and services. When blog posts rank for comparison keywords ("best X tool 2026"), affiliate revenue follows organically.

3. SPUNK Token Economy (spunk.bet)

The casino drives engagement and community through the SPUNK token. Users claim free tokens daily, play games, refer friends, and earn prizes. The ecosystem creates a retention loop that keeps users engaged across the network.

4. Advertising and Sponsorships

As traffic grows, high-traffic tool pages and blog posts become advertising inventory. Tools like the JSON formatter and password generator attract recurring developer traffic that sponsors value.

5. Domain Appreciation

Built-out sites on premium domains appreciate in value. A bare domain is worth $10-100. A domain with a live site, traffic, and content is worth $1,000-50,000+. The network is an appreciating portfolio.

10 Lessons Learned

1. Simplicity Scales, Complexity Does Not

Vanilla HTML loads instantly, deploys in seconds, and never breaks because a dependency updated. React would have added build steps, node_modules, compilation, hydration issues, and a hundred other problems multiplied across 120+ sites. Simplicity was the strategic advantage that made this scale possible.

2. Templates Are Everything

The first 5 pages took the longest because we were establishing patterns. Pages 6 through 200 were fast because the template was proven. Invest heavily in getting your first template right. Every subsequent page inherits that investment.

3. Cross-Linking Is a Superpower

Every page links to every other relevant page. Every site links to every other site. This creates an internal linking web that distributes SEO authority across the entire network. A rising tide lifts all boats, and internal links are the tide.

4. Ship First, Polish Later

Getting 120 sites live in a week meant accepting 85% polish on day one. Every site has been improved since launch. The important thing was being live, indexed, and accumulating traffic and backlinks from day one.

5. Free Tools Are Traffic Magnets

Free tools attract organic search traffic because people search for "free JSON formatter" and "free invoice generator" millions of times per month. Every tool page is a potential traffic engine that runs indefinitely. The tools themselves are the content marketing.

6. GitHub Pages Is Criminally Underrated

Free hosting with custom domains, HTTPS, CDN, and zero configuration. For static sites, there is no reason to pay for hosting. GitHub Pages serves millions of pageviews per month reliably and free. We pay exactly $0/month in hosting across 120+ sites.

7. AI Coding Is Not "Cheating"

Using AI to code is like using a power drill instead of a manual screwdriver. The output is the same. The speed is different. Nobody calls a carpenter a fraud for using power tools. Do not let purists convince you that AI-assisted development is less valid. Results matter.

8. Distribution Matters More Than Product

A mediocre tool with great SEO will get more users than a brilliant tool nobody can find. We invested as much in SEO (meta tags, structured data, keyword targeting, blog content) as in the tools themselves. Build for discoverability from day one.

9. Consistency Beats Creativity

Every site uses the same color scheme, typography, layout patterns, and design language. This consistency builds brand recognition and makes the network feel professional and trustworthy. Creativity is great for individual pages; consistency is what makes a network.

10. One Person Can Build an Empire

The most important lesson: one person with AI can now build what used to require a team. This is not a future prediction. This already happened. The barrier to building on the internet has never been lower. The only remaining barrier is starting.

How You Can Replicate This

Here is the concrete, step-by-step playbook if you want to build your own site network:

Step 1: Choose Your Niche and Domain Strategy

Pick 1-3 related niches. Register domains (or use free GitHub Pages subdomains to start). A tool site + blog content + niche community is a proven formula.

Step 2: Set Up the Stack

Step 3: Build the Template

Create your first page with the AI. Focus on getting the design, layout, navigation, SEO structure, and analytics integration right. This template will be the foundation for everything else. Spend a full day on this if needed.

Step 4: Generate at Scale

With the template proven, tell Claude Code to build new pages following the same pattern. Start with your highest-value tools or content. Build 5-10 pages per day. Push to GitHub. Verify each page loads correctly.

Step 5: Content and SEO

Write blog posts targeting keywords in your niche. Use our SEO Checklist and Meta Generator for every page. Submit your sitemap to Google Search Console. Internal link everything to everything.

Step 6: Monetize

Add ebooks, affiliate links, email capture, or whatever monetization fits your niche. Do not wait until you have "enough" traffic. Monetize from day one so the infrastructure is in place when traffic arrives.

The Minimum Viable Network

You do not need 120 sites to start. A single site with 20 tools and 10 blog posts is a powerful starting point. The key is launching, not launching big. Start with one site, prove the model, then scale. Our 120-site network started with a single HTML file on day one.

What Comes Next

The network continues to grow. Here is what is in progress:

The infrastructure is in place. The templates are proven. The distribution is growing. From here, every new page, tool, or site adds to a network that is already live, indexed, and generating traffic. The hardest part — going from zero to one — is done.

If you are reading this and thinking "I should build something," you are right. And you should start today. The tools exist. The hosting is free. The AI is ready. The only thing missing is you opening a terminal and typing the first prompt.

Start Building Your Empire

Everything we used to build this network is available to you. Claude Code, GitHub Pages, and the entire SpunkArt toolkit. All you need to add is the decision to start.
