So I’ve always had this weird obsession with building my own iMessage agent - like, imagine your own bot living inside your iPhone, sending messages, replying smartly, maybe even trolling your friends a little

Then I found out companies like Linq Blue and SendBlue (both YC) charge over $1000/month just to do this. Yeah, no thanks.

So I built it myself.

iMessageKit is an open-source TypeScript SDK that lets you send and operate iMessages programmatically. Texts, photos, even RCS messages - all through a clean, strongly typed API.

Now I can build iMessage bots and automations without burning cash, and honestly, it feels great to beat the paywalls.

Would love feedback & ideas!
