Build Status Code Climate

asciinema is a free and open source solution for recording terminal sessions and sharing them on the web.

This repository contains the source code of asciinema hosting web app, which runs at asciinema.org.

You can find the source code of asciinema terminal recorder at asciinema/asciinema, and the source code of asciinema web player at asciinema/asciinema-player.

Setting up your own asciinema web app instance

asciinema terminal recorder uses asciinema.org as its default host for the recordings. It's free, public service (all uploaded recordings are private by default though).

If you're not comfortable with uploading your terminal sessions to asciinema.org, or your company's policy prevents you from doing that, you can set up your own instance for private use. See our asciinema web app install guide.

Once you have your instance running, point asciinema recorder to it by setting API URL in ~/.config/asciinema/config file as follows:

url = https://your.asciinema.host

Alternatively, you can set ASCIINEMA_API_URL environment variable:

ASCIINEMA_API_URL=https://your.asciinema.host asciinema rec
