asciinema review
A focused, free open-source tool for recording and sharing terminal sessions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
asciinema is a free, open-source suite for recording, replaying, live streaming, and sharing terminal sessions. It is intended for developers, system administrators, educators, and command-line users creating tutorials, demonstrations, live coding sessions, or reproducible bug reports. The CLI records terminal output and terminal events as asciicast files, rather than conventional video, keeping the product focused on command-line activity. Recordings can be replayed locally, hosted on asciinema.org, embedded in websites, or published to a self-hosted server.
Its strongest fit is the terminal-specific workflow. Users can record sessions, replay them in a terminal, stream locally or remotely, control recording visibility and metadata, search recordings and terminal content, and download plain-text transcripts. The surrounding ecosystem includes the asciinema server, asciinema player, and asciinema.org, with platform coverage across the web, Linux, macOS, an API, and self-hosted deployments. This makes asciinema suitable for sharing command-line demonstrations in documentation, teaching materials, websites, or technical reports without turning the session into a conventional video file.
The main trade-off is its narrow scope. asciinema should be chosen when terminal output, replay, sharing, and text-based session content are the priority. It is less appropriate for presentations or product demonstrations that depend on conventional audiovisual screen recording. Teams that want control over hosting can self-host the asciinema server, while those seeking a hosted workflow can use asciinema.org. Overall, it suits command-line-focused creators who value an open-source format and terminal-native playback more than broader screen-recording capabilities.
