asciinema server¶
asciinema server is a server-side component of the asciinema ecosystem.
It implements a hosting platform for terminal session recordings and live streaming. It offers a familiar web interface for viewing, browsing, sharing and managing recordings and streams. This includes HTTP API, which is used by the asciinema CLI.
The server is built with Elixir language and Phoenix framework. It embeds asciinema's virtual terminal, avt, which is utilized by tasks such as preview generation, recording analysis and live stream state bookkeeping.
asciinema.org is a public asciinema server instance managed by the asciinema project team, providing free hosting for terminal recordings and streams, available to everyone. Check asciinema.org/about to learn more about this instance.
You can easily self-host asciinema server and use the asciinema CLI with your own instance. If you're not comfortable with hosting your data at asciinema.org, if your company policy prevents you from doing so, or if you simply prefer self-hosting everything, then asciinema has you covered.
Notable features:
- hosting of terminal session recordings in asciicast format,
- live streaming with WebSocket-based protocols for real-time terminal session broadcasting,
- perfectly integrated asciinema player for best viewing experience,
- easy sharing of recordings via secret links,
- easy embedding of the player, or linking via preview images (SVG),
- privacy friendly - no tracking, no ads,
- visibility control for recordings: private, unlisted, public,
- editable recording metadata like title or long description (Markdown),
- configurable terminal themes and font families (including Nerd Font variants),
- download of plain text versions (
.txt) of recordings.
