I'm an apprentice developer and built a free-proxy checker because 95% of public lists are dead

I'm doing my apprenticeship as an application developer in Germany, and in my free time I kept hitting the same wall: free proxy lists are almost all dead, and some of the live ones tamper with the pages they return. So I built proxy-scraper. It pulls from 700+ sources, confirms each proxy on two sites, checks that pages come back unchanged, tests TLS, and learns which sources are worth fetching. A GitHub Action refreshes a public list every six hours, and it can run as a loca

痛点：免费代理列表中绝大部分已经失效，而其中仍然存活的代理会篡改返回的页面内容，导致开发者难以验证代理是否安全可用

目标用户：爬虫、数据采集和测试工程师，以及需要大量低成本的代理来做SEO监控、价格抓取的小团队

证据：free proxy lists are almost all dead, and some of the live ones tamper with the pages they return. / What I learned: the hard part isn't finding proxies, it's proving one is actually safe to use for a test.

变现：提供带存活检测和内容完整性校验的托管轮换代理 API（按请求量计费）；或反过来面向代理供应商销售“代理池质量验证”白标 API 和监控面板

MVP：把现有的 700+ 源抓取和双站验证脚本封装成一个 REST API：调用时传入目标 URL，返回验证过的代理以及响应哈希一致性校验结果，用 Stripe 按调用次数收费，并把 GitHub Action 每 6 小时刷新一次改成实时刷新

竞品：Bright Data、Oxylabs、ProxyScrape、free-proxy-list.net、Scrapy-rotating-proxies

摘要：德国一名学徒开发者做了一款免费代理检查器 proxy-scraper，它从 700+ 来源抓取代理，在两个站点上验证代理是否存活，并检查返回页面是否被篡改、TLS 是否正常；每 6 小时通过 GitHub Action 发布一份公开代理列表。该帖子只是开源免费发布，没有提到任何付费意愿或收入数据，而免费代理用户本身付费意愿很低，变现需要转向“代理质量验证和托管轮换代理”方向。
