What Terminalizer is
Terminalizer records terminal sessions and produces animated GIFs or web players that can be embedded in a website. Each recording is saved as an editable YAML file, allowing users to change frames and delays before rendering. Customization includes colors, fonts, window frames and CSS styles. The documentation also lists GIF quality and repetition controls, frame skipping, cursor styles and watermarks. Users can upload a recording to terminalizer.com with the share command and receive a link to its web player; an account is used for online sharing. The maker describes Terminalizer as open source, and its GitHub repository is under the MIT license. It is available for Linux, macOS and Windows. GIF compression is not implemented, and the documentation recommends using an external compressor. Support links point to Gitter and GitHub Issues.
