asciinema is a suite of tools for recording, streaming, and sharing terminal sessions. It is free and open-source software (FOSS), created by Marcin Kulik.

Its typical use cases include creating tutorials, demonstrating command-line tools, live coding, and sharing reproducible bug reports. It focuses on simplicity and interoperability, which makes it a popular choice among computer users working with the command-line, such as developers or system administrators.
