Castmill
Castmill
An AGPL platform with a modular HTML5 player aimed at low-memory devices.
- Open source
- Free tier
- Self-host
Castmill has been in development since 2016 and is built as a set of packages rather than one application, with a dashboard component and a lightweight HTML5 player that can run in a browser or be embedded into a device. The player is written for reliability on constrained hardware and keeps working offline. Its repository topics name Android and webOS as target devices. The AGPL licence means offering it onward as a service carries obligations.
Capabilities
