서버 비용이 0인 AI 기반 스택 오버플로 대안을 구축한 방법

Stack Overflow is declining. Everyone uses AI to fix bugs now. But there’s a problem.

When ChatGPT solves your bug — that answer disappears. The next developer with the exact same problem has to re-ask from scratch.

So I built CodeAnswr.

How it works

1. You ask a question (code problem, error, architecture question)
2. AI answers you — you chat back and forth until solved
3. The final Q&A gets published automatically as a searchable page
4. Next developer Googles the same error → finds your solved thread

What makes it different

Feature Stack Overflow CodeAnswr Answer speed Hours/days Instant (AI) Privacy scanner ❌ ✅ Catches secrets before posting Job board Paid Free (AI-matched) Geographic restrictions Some None (crypto payments) Bounty system ✅ ✅ (crypto rewards) Server costs Massive ~$0 (Cloudflare Workers)

Tech Stack

• Frontend: Svelte + Cloudflare Pages
• Backend: Cloudflare Workers + D1 (SQLite at the edge)
• Auth: Google OAuth
• Payments: Crypto (no geo-blocking)
• Total monthly cost: Under $5

What I shipped in 6 months post-launch

• 🏢 AI Job Hub (companies post jobs, AI matches developers)
• 💰 Bounty System (crypto rewards for best answers)
• 🌍 Crypto payments (works for devs in any country)
• 🔒 E2E encrypted private questions
• 👤 Public developer profiles with contribution history

Biggest surprise

The privacy scanner — it scans your code for API keys and tokens before you post. I built it as an afterthought. It’s now the most-mentioned feature in every review.
