    SimGate▲6

    Hi HN, I built a small developer tool called *SimGate*. Problem: most SMS APIs (Twilio, etc.) charge per-SMS. For small projects, prototypes, or local businesses, this adds up quickly. What I made: - An Android app that connects your phone to the cloud via WebSocket. - A simple REST API where you send JSON (`deviceId`, `phoneNumber`, `message`). - Your phone sends the SMS using its own SIM plan — no extra per-SMS fees. Use cases: OTP codes, alerts, internal tools, or any project where you just need reliable SMS without provider costs. Stack: Node/Express + Websockets (backend). Demo &…

    SMS Interface for Stable Diffusion▲50

    If you text 8145594701, it will send back an image with the prompt you specified. Currently only US numbers can send/receive texts because Twilio. Sorry to the rest of the planet! I think this will likely fall over but I figured this would be a cool little thing to demo. I removed the NSFW filter so be mindful of your prompts! I don't persist numbers and there is no linkages being saved between the original text message and the generated images.
