Check which network routes and Cloudflare nodes various AI services use.

想知道代理是不是真的把每个 AI 站都送到同一个出口? 答案:并不是。 我做了一个 AI 分流测试: 它会探测 ChatGPT、Sora、OpenAI、Claude、Grok、Anthropic、Perplexity 等 AI 服务,通过读取各站点的 Cloudflare Edge Trace 信息,获取实际访问情况: 出口 IP Cloudflare 边缘节点(colo) HTTP / TLS / WARP 状态 访问延迟 然后根据落地位置进行归组。 这次测试结果: 6 个服务(覆盖 7 个域名)走美国出口。 唯一例外是 Sora,落在东京节点。 也就是说,同一个代理配置下,不同 AI 服务并不一定经过同一个出口。看起来“都能访问”,实际线路、节点和落地点可能完全不同。 整个测试工具纯前端实现,零后端。

A visual roadmap you branch instead of overwrite: both timelines stay, each with its decision. Syncs from Linear, Jira and GitHub, so a shared link stays true.

Roadmark: version control for product roadmaps. Branch the plan to compare scenarios, and every change carries the why, so a date that moved six months ago isn't a mystery today.

Create visual boards that group ideas by color and structure them with branches, then share without login.
@shiftibis · X
Indie project 📝 ReBox: visual boards where color = group and branches = a file tree — both at once. Share links open without login (anyone with the link can edit). A Claude connector builds boards for you. English UI just shipped. #buildinpublic

Not really a startup. It's just something I built for myself a simple note taking app with a planner, progress tracker, and mind map I'm going to share it publicly @NodesMap check it
