Inspiration
Finding quality free browser games shouldn't be hard. Most gaming sites are cluttered with aggressive ads, require downloads, or push you to create accounts for games that could easily run in a browser. I wanted to build something cleaner — a massive, free gaming platform where you just click and play. I also wanted to see how far AI-assisted development could take a project in a single extended session.
What it does
https://fastplaygames.com is a free browser gaming platform with 32,000+ HTML5 games across 22 categories — action, puzzle, racing, sports, strategy, and more. Every game plays instantly in your browser with no downloads or sign-ups required. The site also includes 30 free online tools (dice roller, tip calculator, BMI calculator, password generator, etc.) and 1,000+ curated content pages including best-of lists, "games like" alternatives, educational games, and unblocked games for school. Available in 20 languages, optimized for desktop, mobile, tablet, and Chromebook.
How I built it
- Frontend: React 19, TypeScript, Vite, Tailwind CSS
- Hosting: Firebase Hosting with custom domain
- Games: 500+ hand-built HTML5 canvas games + 31,000+ partner games via GamePix and GameDistribution APIs
- SEO: Custom build-time prerendering system that generates 66,000+ unique HTML files with per-page meta tags, structured data (JSON-LD), hreflang tags, and SSR body content
- AI Tools: Claude was used extensively for code generation, content creation (860+ SEO pages), schema markup, and architecture decisions
- i18n: 20 languages with translated UI strings and multilingual sitemaps
- Tools: 30 functional React components (calculators, generators, converters) — each fully interactive, not placeholders
Challenges I ran into
- SPA indexability: As a React SPA, every URL returned identical HTML. Google couldn't distinguish 32,000 game pages. Solved with a build-time prerendering script that generates unique HTML per route with custom meta tags, schema, and static body content.
- Game data scale: Loading 32,000 game records (7MB+) on every page killed performance. Solved by code-splitting game data into separate chunks and stripping modulepreload hints from prerendered pages.
- Firebase storage limits: With 66,000+ HTML files at ~1MB per deploy, we hit the free tier storage quota after many deploys. Had to manage release retention.
- Thumbnail quality: External games from partners had varying thumbnail quality. Built a scoring system that prioritizes games with proven engagement (play counts) over arbitrary category boosts.
Accomplishments that I'm proud of
- 32,000+ playable games from day one — not a slow build-up
- 99,000 sitemap URLs across 8 sitemaps with zero duplicate content issues
- 1,000+ original content pages — every one with structured HTML, FAQ schema, and cross-linking
- 30 fully functional tools — not placeholders, each actually works (the password generator uses crypto-secure randomness, the BMI calculator has imperial/metric toggle, etc.)
- 20-language support with prerendered multilingual pages
- AI-optimized: llms.txt, 31,000+ markdown files, and robots.txt welcoming all AI crawlers
What I learned
- AI is a force multiplier for scale — Writing 860 SEO pages with structured HTML and FAQ schema by hand would take months. With Claude, it took hours.
- Prerendering beats SSR for static content — A build-time script that customizes tags per route gives 90% of SSR's SEO benefit with zero server infrastructure.
- Free tools are underrated for gaming sites — Dice rollers, calculators, and generators bring in non-gaming traffic and earn natural backlinks from completely different audiences.
- The game distribution model scales instantly — Partner with GamePix and GameDistribution to access tens of thousands of HTML5 games on day one.
