I build live production tools that run on your own device.
Creator of CastDeck Local — a self-hosted live studio focused on browser-based video calls, multistream and local recording.

I'm a Brazilian developer and live-production enthusiast. I build software for creators, churches, schools and independent broadcasters who want professional shows without depending on a cloud studio.
My main project is CastDeck Local: open a desktop app, invite guests with a browser link, compose the scene, record locally and stream to multiple destinations. The video call is the center of the product — not an afterthought.
StreamYard alternative, with the video call first.
Browser guests · mix-minus · scenes · local MP4 · multistream · 16:9 + 9:16 · open source.
- Guests by link — no account, no install, Chrome/Edge on phone or desktop.
- Real mix-minus — guests hear the program, not their own delayed voice.
- Scenes and layouts — host + guests, preview/PGM, screen share, camera by QR.
- Pro audio — mixer, dBFS meters, buses, noise reduction and talkback.
- Delivery — RTMP/RTMPS/SRT multistream, local MP4 recording and simultaneous vertical 9:16.
- Open source — AGPL-3.0-only, with an optional commercial license.

- Local-first: your video, audio and keys stay on your machine.
- Video call first: the guest experience is the product, not a checkbox.
- Boring reliability: local recording, predictable costs, no plan limits.
- Open by default: AGPL-3.0 code, documented architecture, clear licenses.
- Honest engineering: know the limits, measure, and say what does not work yet.
