I built a listener that checks 40 subreddits and a few X lists every hour that tells me which threads are speeding up.

This started as a Saturday project and it's now the first thing I open in the morning. I kept finding the good threads in my niche a day late, after they already had 200 comments and my replies would land dead. I built a small listener for it.

痛点：做 Reddit/X 社区运营和内容营销的人总是晚一天发现正在爆发的帖子，等到回帖时已无人看，缺少按各版块自身基线判断“帖子是否在加速”的预警工具

目标用户：独立开发者、增长/内容营销人员、社区运营者，以及靠 Reddit/X 引流的小团队

证据：I kept finding the good threads in my niche a day late, after they already had 200 comments and my replies would land dead. / It pings me when a thread is moving faster than that sub normally does, with the link and a one line summary / The data calls cost me a little over a dollar a day. / I'd like to know how you set your thresholds

变现：订阅制 SaaS：免费版 3 个监控源 + 每小时轮询，付费 19–29 美元/月提供更多 subreddit/X 列表、实时（5 分钟）轮询、Slack/Telegram/邮件多通道告警和情绪/吵架识别；也可做一次性买断的自托管脚本版本

MVP：两周内用 Python + cron + SQLite + Telegram Bot 复刻核心：抓 20 个 subreddit 的新帖前 3 小时评论增速，除以该版块自身中位数得出“加速倍数”，超过阈值推链接+一句话摘要；加一个简单的 Web 配置页（增删监控源、阈值）和 Stripe 付费墙即可上线

竞品：Syften、F5Bot、Brand24、GummySearch、Notify

摘要：作者用 Python + cron + SQLite + Telegram 做了个监控器，每小时扫描 40 个 subreddit 和若干 X 列表，按各版块自身评论增速中位数判断帖子是否在“加速”，数据成本约每天 1 美元多。难点在于区分“吵架式爆发”和“有价值的讨论”，作者公开征集阈值设置经验。帖子本身没有付费意愿或收入证据，但需求场景清晰、单人两周可复刻，适合做成低价订阅的社交监听工具。
