Why I built this: I needed to send a few hundred texts for a local event — reminders, updates, that kind of thing. I looked at the usual options and every single one assumed I was a call center: $29+/mo subscriptions, or Twilio, which meant registering a business, getting a number approved, and paying per message on top of a monthly fee. All for something I'd use a handful of times a year.
That felt backwards. I already have a phone number and a texting plan I pay for every month — why do I need to rent a second one and pay per message just to send texts to more than one person at a time?
The problem I was actually solving: occasional bulk texting for small use cases — a local business reminding customers about an appointment, an event organizer sending updates, an agent following up with a list — doesn't need enterprise SMS infrastructure. It needs a way to send from your own number, personalized, without turning it into a recurring bill.
How the approach evolved: My first version was pretty barebones — just fire off messages from a CSV. But testing it myself, two things became obvious fast:
People don't want their contact lists sitting on someone else's server. So everything stays local on your Mac — nothing gets uploaded anywhere.
Sending too fast looks like spam to carriers and gets you blocked. So I added randomized delays between sends to mimic how a person actually texts.
That's really been the guiding rule the whole way: build the thing I'd actually trust to text my own customers/contacts, not a stripped-down demo of an enterprise tool.
Would genuinely love feedback — especially if you've been burned by carrier filtering, Twilio's 10DLC process, or just paying for tools you barely use. That's exactly who I built this for.
