FastCast

FastCast

A native Windows screen recorder and live streaming app.

FastCast helps creators record locally and stream to custom RTMP/RTMPS endpoints with desktop audio, microphone capture, and a webcam overlay — a simpler workflow than OBS for focused single-scene recordings. Choose a monitor or window, pick your audio, and record MP4 or go live without setting up scenes first.

Quick captures without scene setup

FastCast focuses on the common path: choose a screen or window, choose audio, add an optional webcam overlay, then record or stream. It is designed for lightweight Windows capture workflows during Open Beta.

SmartScreen

FastCast is currently unsigned, so Windows SmartScreen may show an "Unknown Publisher" warning. If you trust the download source, click More info -> Run anyway. If that is a dealbreaker, do not run it yet.

Open Beta status

FastCast Free remains free during the Open Beta and covers simple 1080p30 recording and streaming. FastCast Pro is an optional paid license (activated in the app via Lemon Squeezy) that unlocks 1440p/4K recording and 60 fps capture where your hardware supports them, plus advanced encoder controls. There are still no accounts and no telemetry; license activation is user-initiated and local-first.

Known limitations

  • No scene system / multiple sources yet
  • No chroma key or filters yet
  • No multistream / simulcast yet
  • No platform OAuth yet
  • Intel hardware encoding is not broadly validated yet; software fallback is included
  • App is unsigned during Open Beta
