I Built 11 Web Apps in One Night Using AI

Source: Dev.to

Last night, I sat down with one goal: build as many functional apps as possible using AI. No planning. No roadmap. Pure YOLO mode.
By sunrise, I had 11 deployed applications — including 2 games, 6 SaaS tools, and 3 developer utilities. Total infrastructure cost: $0/month.

The Stack

• AI IDE: Google Antigravity (Claude Opus 4.6 + Gemini 3 Pro)
• Deployment: Vercel (free tier)
• Backend: Google Cloud e2‑micro (free tier, 24/7)
• AI API: Gemini API (25,000 credits/month with AI Ultra)

The 11 Apps

🎮 Games

1. Void Dealer – A tarot‑themed roguelike deckbuilder inspired by Balatro. Features 56 Minor Arcana + 22 Major Arcana with unique power effects, a shop system, and a 9‑round progression.
2. Neon Survivors – Vampire Survivors‑style auto‑shooter with neon aesthetics. Includes 5 weapon types, wave‑based spawning, boss battles, and an XP upgrade system.

🛠️ Developer Tools

3. CommitCanvas – Visualize your GitHub commit history as art. Multiple themes: Matrix, Aurora, Galaxy, City Skyline.
4. MarkCraft – Convert Markdown to platform‑optimized formats: blog HTML, Twitter threads, plain text.
5. DevLetter AI – Privacy‑first AI cover‑letter generator with BYOK (Bring Your Own Key).
6. BrowserGuard – Local proxy preventing multiple AI agents from conflicting on browser access.

📊 SaaS Tools

7. TrendRadar – AI‑powered trend monitoring from RSS, Hacker News, Reddit, and YouTube.
8. CardCraft AI – AI greeting‑card generator with custom templates and Gemini‑powered messages.
9. ContentForge – Write once, publish everywhere. Converts blog posts to Twitter/X, LinkedIn, YouTube descriptions, and more.
10. SocialPulse – Unified social‑media dashboard aggregating data from multiple platforms.
11. AutoRevenue – LLM‑powered automated content‑generation system running 24/7 on Google Cloud.

Key Lessons

1. AI is a multiplier, not a replacement – Every app still required architectural decisions and design taste. AI eliminated boilerplate; I provided direction.
2. Vanilla JS wins for speed – All 11 apps use HTML + CSS + Vanilla JavaScript. No frameworks, no build steps. index.html → deploy → done.
3. Decision‑making is the bottleneck – AI generates code in seconds. The bottleneck was deciding what to build and for whom.
4. Ship immediately – Every app was deployed within minutes of “good enough.” Perfect is the enemy of shipped.

What’s Next

• Stripe integration for CommitCanvas Pro ($4.99/mo)
• Steam launch for Void Dealer
• Product Hunt launch for CommitCanvas
