A no-account Windows tool for quick screen recording and streaming
FastCast is a Windows tool for quickly recording the screen and optionally sending a live stream. It is in beta, runs from a portable ZIP file, and does not require an account. It can record a monitor or a single window, include and computer audio, add a webcam overlay, and save the result as an MP4 file.
It can also stream to a custom RTMP or RTMPS address. Video is saved with H.264 and audio with AAC, with output choices for , 1080p, or 720p. Hardware H.264 has been tested on NVIDIA and AMD s, and a software backup option is included.
It is not trying to replace OBS or advanced broadcast tools, so it does not yet include scenes, filters, chroma key, multistreaming, or platform login support. It is free during the open beta, but the app is currently and unsigned, so trust and safety need extra care.
