About asciinema
asciinema records what happens in a terminal as text rather than video. Running asciinema rec demo.cast starts a recording, and exiting the shell ends it. Because recordings are text, viewers can pause the player and copy and paste commands straight from it.
Recordings can be shared on asciinema.org, which also hosts live streams, or embedded in blog posts, documentation and slides with the asciinema player. It suits developers writing tutorials or showing how a command-line tool works.
Strengths
- Sharp, small recordings instead of blurry video
- Text in recordings can be copied from the player
- Embeddable player for docs and slides
- Live streaming of terminal sessions
Limitations
- Records only terminal output, not graphical applications
- Recordings need the asciinema player rather than a standard video player
