Building a rate-limited blog thread AI tool on Cloudflare Workers (no login, no DB)

说明与用途

Blog2Thread 允许用户粘贴博客 URL 或文本，立即生成推文线程，使用 Cloudflare KV 和 cookie 进行速率限制，无需登录或用户数据库。

问题

Indie makers need a frictionless draft tool that lets users paste a blog URL or text and instantly get a ready-to-post Twitter thread without requiring signup or storing user data, while preventing abuse.

结果

Blog2Thread provides a zero‑friction, no‑login AI thread generator with robust rate limiting, enabling indie makers to offer a free draft experience while protecting against abuse.

工作流

• 1. User pastes blog URL or text on the front‑end.
• 2. Front‑end sends request to Cloudflare Worker.
• 3. Worker reserves a generation slot using Cloudflare KV counters (cookie, IP, burst limits).
• 4. If reservation fails, return 429 error.
• 5. Worker calls an OpenAI‑compatible API to generate the thread.
• 6. On success, return the thread to the user and persist the draft ID for sharing.
• 7. On failure, rollback the reservation to free the quota.
• 8. Dynamic Open Graph metadata is generated from the first 4 tweets for social previews.
• 9. User copies the thread and can optionally schedule or distribute via paid tools.

证据

No account. No database of users.

Pattern: reserve before generate → rollback if the model call fails
