I built Legcast, a Chrome extension that runs my darts stream for me. Now I have to find the few thousand people it's for

I'm a darts player from the Netherlands and I stream my home matches on TikTok. Between every throw I was clicking around in OBS: switch camera, show the score, save the clip. So I built Legcast, a Chrome extension that reads the match from the scoring app I use (DartCounter) and runs OBS for me: camera switching, zoom on finishes, replays of the game shot and a clip of every 180. The hardest part was teaching it to find the dartboard in the camera image, so it knows where to zoom. It just

痛点：业余体育赛事直播者（如飞镖）在每投之间要手动在 OBS 里切镜头、显示比分、保存精彩片段，操作繁琐且无法专注比赛。

目标用户：在家直播比赛的飞镖/桌球/保龄球等小众运动的业余玩家，主要在 TikTok 和 Facebook 群组活动。

证据：Between every throw I was clicking around in OBS: switch camera, show the score, save the clip. So I built Legcast... The audience is tiny: darts players who stream. Most of them hang out in a few Facebook groups and on TikTok.

变现：Chrome 扩展免费+订阅制（如每月 5-8 美元解锁多运动模板、云剪辑上传、去水印）；或按赛事/俱乐部打包授权；配合一次性的“自动化直播模板”付费包。

MVP：已有可用版本，2 周内可横向复制：把 DartCounter 积分读取抽象成可配置的“比分适配层”，先做 1-2 个相邻运动（如台球/保龄球）+ 一个 OBS WebSocket 通用控制面板，用录屏 Demo 在 Facebook 群组和 TikTok 做冷启动验证付费意愿。

竞品：OBS 自带自动化脚本/WebSocket 插件、Sportscode 等专业体育剪辑工具、DartCounter 官方 App 的分享功能、各类 AI 自动导播/自动剪辑 SaaS

摘要：荷兰飞镖玩家为省去在 OBS 里手动切镜头、切比分、存片段，自己做了 Chrome 扩展 Legcast，能从 DartCounter 读取比分并自动控制 OBS 完成镜头切换、终局特写、重放和 180 分剪辑，已上架 Chrome 商店。作者坦言受众极小——只有“会直播的飞镖玩家”，目前卡在如何找到前几千名用户，帖内没有任何付费或收入数据，属于自用需求被动产品化，变现意愿尚未验证。
