Tired of scrapers getting instantly flagged? I Built a lightweight async Python scraper with HTTP/2 and anti-bot detection (httpx)

Hey everyone, Most developers waste hours configuring heavy headless browsers just to scrape basic targets, only to watch them get blocked anyway because of outdated TLS signatures or missing headers. I got tired of the bloat, so I put together a clean, high-performance alternative: resilient-async-scraper. It’s a lightweight async utility built with httpx that handles HTTP/2 fingerprint matching out of the box, randomizes realistic browser User-Agents, and actively catches a

AI 分析

痛点:开发者为了抓取基础目标,耗费大量时间配置笨重的无头浏览器,却仍因过时的 TLS 指纹和缺失的请求头被目标站点秒封,并且不知道何时该轮换代理池。

目标用户:做数据采集的独立开发者、小型数据团队、需要绕过反爬的中小 SaaS 或爬虫工程师

证据:Most developers waste hours configuring heavy headless browsers just to scrape basic targets, only to watch them get blocked anyway because of outdated TLS signatures or missing headers. / actively catches anti-fraud status codes (403, 429, 503) so you instantly know when your proxy pool needs rotation

变现:开源核心库免费引流,对「托管版反爬 API / 智能代理轮换服务 / 指纹与请求头持续更新订阅」按请求量或月费收费(免费额度 + 付费套餐),或提供 IP 代理与指纹池的绑定套餐。

MVP:两周内做一个托管 SaaS:接收目标 URL 与解析规则,后台用 httpx + HTTP/2 指纹伪装 + 自维护的 UA/Header 池执行请求,内置 403/429/503 监控与代理自动轮换;前端提供仪表盘展示成功率、封禁率与请求日志,先只支持 JSON 与 HTML 抽取两种输出。

竞品:Scrapy、curl_cffi、cloudscraper、Playwright、ZenRows、ScrapingBee、Bright Data、Apify、ScraperAPI

摘要:这是一位开发者在 r/SideProject 发布的开源异步爬虫工具 resilient-async-scraper,基于 httpx 实现 HTTP/2 指纹匹配、UA 随机化和 403/429/503 反爬状态码检测,主打轻量、无重依赖、替代笨重的无头浏览器。帖子本身是纯开源免费发布,没有任何付费意愿或收入数据,需求痛点(被封、代理轮换)在爬虫圈真实且普遍,但该赛道竞品极为密集,变现需靠托管 API/代理订阅做差异化。
