About

Hey, I'm Petro. I make software and music, and there's usually another project on the way. I created Corneta to help streamer friends multistream without the hassle. It's a free, open-source Windows app that works with OBS to stream to multiple platforms and bring their chats together. I'm founder and CTO at Growth Edge, building software and AI agents for sales teams, and a partner at Growth Machine. I also build Guarita: security checks for AI-built apps, with findings explained in plain language and fix prompts for your coding assistant. With Experi, I'm bringing challenges and rewards to apps and customer loyalty programs through an API or a campaign builder. I write about what I'm building and learning at pitrol.dev.

Corneta - Multistream from OBS, straight from your PC

You keep building your scenes in OBS. Corneta receives that signal on your Windows PC and sends it to the platforms you pick (Twitch, YouTube, Kick or any RTMP server), with the chats in one place. You can set the quality per platform and record the stream with its chat to watch later. With drop protection on, a BE RIGHT BACK screen keeps the stream up if OBS crashes. Free and open source (MIT), no account needed. Each platform uses your own upload.
