CalendarPipe

CalendarPipe is what happens when someone actually pays attention to the OAuth friction problem — instead of making you authenticate on behalf of AI agents, it just sends them their own hosted calendars that fire real invitations over email, which is frankly how it should have worked from the start. The programmable pipes thing is the real differentiator here: you're not stuck mirroring everything or whatever arbitrary settings a sync tool decides to expose, you write actual functions that take an event in and decide what comes out, and you can build those visually, describe them in plain English to the AI, or write TypeScript if you're that kind of person. Getting 137 upvotes and climbing on Product Hunt suggests the timing is right too — as AI agents start needing actual calendars, being the infrastructure layer that makes that possible without OAuth headaches is a legitimately smart position to occupy.
