I built 9 free web tools and printed the entire backend on every page. What should number 10 be?

说明与用途

作者创建了九个轻量级的 Web 工具，用户无需注册即可查看完整后端代码，确保透明度和可复现性。这些工具将 URL 转换为 Markdown、JSON、YAML，检查链接、robots.txt 和图片 alt 文本，并公开 MCP 接口供代理使用。

问题

Developers need lightweight, no‑sign‑up web tools that expose their full backend code for transparency and reproducibility.

结果

The nine tools provide transparent, lightweight web utilities that expose their full backend code, enabling developers to verify, adapt, or extend them without sign‑ups or hidden APIs.

工作流

• 1. User pastes a URL into the tool’s web form.
• 2. The tool fetches the target page’s server‑rendered HTML.
• 3. It processes the content (e.g., converts to Markdown, JSON, YAML, or checks links).
• 4. The tool returns the processed result and the full source code of its backend on the same page.
• 5. Users can copy the code, run it locally, or integrate it into their own workflows.

证据

Every tool prints the complete source code of its own backend, right there on the page.
