Hey HN! I built CodeAnswr because I noticed a problem: everyone now
solves coding problems with AI, but those solutions never get published
anywhere searchable. Stack Overflow is dying because of it.
CodeAnswr is the fix — AI-assisted Q&A where the final answer gets published publicly, so the next developer searching for the same problem finds it instantly.
Key things I tried to get right: - Privacy scanner strips API keys, passwords, AWS creds before anything is stored or published - Built entirely on Cloudflare Workers + D1 + Pages — zero server costs - AI is Puter.js (free, unlimited) — no API key required from users - Full translation for 10 languages while preserving code blocks - MCP server so Claude/Cursor users can query it directly
Stack: SvelteKit + Hono.js + Cloudflare D1 + Puter.js Repo: https://github.com/mobinpo/Implementing-Developer-Hub-APIs
Would love feedback, especially on the privacy scanner and the publish-review flow.
Show HN: CodeAnswr – Stack Overflow alternative with E2E encryption
Built this after seeing developers leak credentials on SO daily. Key features: (1) Privacy scanner with 20+ detection patterns (2) Client-side RSA encryption for sensitive questions (3) AI job matching based on actual contributions. Stack: Cloudflare Workers + D1 + Vectorize. Runs on 100% free tier. Looking for feedback on the crypto implementation.
