Asciinema

A terminal recording server that captures shell sessions and turns them into shareable, replayable asciicast files. It records keystrokes and output with precise timing so playback reproduces the session as it happened, including colors and cursor movement.

Teams use it for demos, onboarding walkthroughs, debugging sessions and sharing reproducible steps with colleagues.

Running your own instance keeps recordings of internal systems inside your network, removes the dependency on a hosted sharing service, and lets you decide how long sensitive sessions are retained.
