CastSponsorSkip is a Go program that uses the SponsorBlock API to skip sponsored YouTube segments and skippable ads on local Google Cast devices.
About Chromecast
CastSponsorSkip is an open-source Go program that monitors Google Cast devices on a local network. When a Cast device starts playing a YouTube video, it retrieves sponsored segment data from the SponsorBlock API and seeks to the end of those segments; it also looks for skippable YouTube ads and presses the skip button when it appears. Devices must be reachable on the same LAN, and Docker or Kubernetes deployments require host networking for discovery to work. It can be configured through environment variables, command-line flags, or a config file, and is distributed as Docker images, a Helm chart, and packages for APT, RPM, AUR, and Homebrew.
