About:
asciinema is a command-line tool for recording terminal sessions and uploading them to the web for sharing. It captures terminal output as structured text data rather than video, enabling lightweight recordings and efficient playback. The tool supports local saving and streaming to the asciinema.org platform or self-hosted servers.

Key Features:

Text-based recording for small file sizes and fast sharing
Instant playback in any modern web browser
Native terminal playback via the 'asciinema play' command
Embeddable player for websites and documentation
Open-source with a self-hostable server option

Use Cases:

Creating bug reports with reproducible terminal steps
Producing software tutorials and command-line demos
Sharing quick CLI workflows with teammates
Building documentation with embedded terminal recordings

Alternatives:

script – Unix 'script' logs raw text but lacks web playback and sharing features
Terminalizer – Renders GIF/WebM animations; heavier files and not text-based
Showterm – Similar web recording service; asciinema is open-source and self-hostable
