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

Would love feedback, especially on the privacy scanner and the publish-review flow.
