I got tired of broken follower trackers, so I built my own lightweight alternative

Hey everyone, A few months ago, I was looking into how third-party Instagram analytics tools handle recent follower activity. Most existing apps out there felt bloated, required full account credentials, or broke constantly whenever Instagram tweaked its backend. So I decided to build a simple, lightweight web utility called checklastfollow.com as a personal project to see if I could handle the data fetching smoothly without hitting severe rate limits.

AI 分析

痛点:现有第三方 Instagram 粉丝追踪工具臃肿、要求完整账号凭证、且平台一改后端就频繁失效,用户需要轻量、免登录的替代品。

目标用户:想查看近期取关/新增粉丝的 Instagram 普通用户与中小内容创作者

证据:Most existing apps out there felt bloated, required full account credentials, or broke constantly whenever Instagram tweaked its backend. / It's live and working, but I'm still tuning performance under higher traffic loads.

变现:免费+高级订阅(更多历史记录、批量分析、导出)或广告/联盟;也可先做 API 数据服务卖给其他开发者,但需先验证付费意愿。

MVP:两周内做一个免登录的「最近取关者/新粉丝」查询页:输入用户名即返回近 7 天变动列表,缓存结果降低请求频率,用 Stripe 加一个 9 美元/月的历史记录订阅入口测试付费转化。

竞品:Instagram 内置关注列表、Social Blade、Followers & Unfollowers 类 App、Iconosquare、各种第三方取关检测工具

摘要:作者受不了现有 Instagram 粉丝追踪工具臃肿、要账号密码且经常因平台改后端而失效,自己用 Next.js + Node.js 做了免登录的轻量替代品 checklastfollow.com,目前在线运行并调试高流量下的性能。帖子仅为发布求反馈,未提及任何收入或付费数据,且该赛道已有大量免费竞品,且依赖抓取 Instagram 存在封禁与合规风险。
