Asciinema

Asciinema is a free and open-source command-line tool for recording terminal sessions, sharing them on the web, and replaying them in a terminal or web browser. The PyPI package (version 2.4.0) represents the stable Python-based CLI, which captures terminal output into lightweight text-based `.cast` files. While active development for the core CLI has transitioned to a Rust rewrite (version 3.x, not distributed via PyPI as a Python package), the 2.x Python version remains widely used and maintained.
