I built BusyTwin: it mirrors your Google and Outlook calendars as private “Busy” blocks so you stop getting double-booked

The problem: I have a personal Google calendar and work calendars in Microsoft 365, and they don’t talk to each other. Colleagues would book me over a dentist appointment; friends would plan over a client call. Existing tools were either pricey, Google-only, or wanted to copy all my event details everywhere. What I built: BusyTwin connects your calendars and creates a private “Busy” twin of every event in the others, both ways. Move or cancel the original and the twins follow. By defaul

AI 分析

痛点:个人 Google 日历与工作 Microsoft 365 日历互不相通,导致被同事或朋友重复预约私事/会议,用户只能手动对照多个日历排期。

目标用户:同时使用多个日历生态(Google + Microsoft 365)的职场人士、自由职业者、顾问和需要对外预约的人。

证据:Colleagues would book me over a dentist appointment; friends would plan over a client call. Existing tools were either pricey, Google-only, or wanted to copy all my event details everywhere.

变现:订阅制 SaaS(免费额度引流 + 月/年订阅),或按日历连接数/预约页数量分级收费,可对标 Calendly/Reclaim 的定价。

MVP:用 FastAPI 接入 Google Calendar API 与 Microsoft Graph,仅实现双向'Busy'块镜像同步 + 推送通知,OAuth token 加密存储,先做单用户可用版本,两周内可上线核心同步,预约页等功能放二期。

竞品:Reclaim.ai、Clockwise、CalendarBridge、OneCal、Calendly、Motion

摘要:开发者用 Python+FastAPI 独立做出 BusyTwin,把 Google 与 Microsoft 365 日历双向镜像为私有『Busy』块,解决跨日历重复预约问题。已有 Calendly 式预约页、自动会议链接、合并 ICS 订阅等功能,部署在 12 美元/月的 DigitalOcean Droplet 上,含约 190 个自动化测试。但帖子仅有作者自述痛点,无付费用户或收入数据,且该赛道已有多个成熟竞品。
