Lizard, the 8ch monitor

Lizard is a command line (CLI) program for monitoring 8ch threads. After you add a thread to its watchlist, it can connect to 8ch and check if new replies were made, notifying you if so. It will try to keep a local copy of the thread and the files in it in case the thread dies. It can also open all threads with new replies in your browser with a single command.



  1. Make sure you have Python 3
  2. Download the most recent .whl package from under dist/
  3. Install with pip: pip3 install lizard-0.<VERSION HERE>-py3-none-any.whl

If upgrading, see wiki.


Running lizard without any arguments will print the help message explaining the syntax. It will also create a ~/lizard_data directory to store files.

After you install, run lizard create to create a new database (if you don’t have one already). Everything else will crash unless a valid database exists.

Add a thread to the database with lizard a <URL>. Upon adding a thread, Lizard will immediately download a copy of the thread and the files in it. These will be put under ~/lizard_data/.

You can call lizard r to refresh threads currently in the database, and see their status with lizard l. lizard rl combines these two steps. If you see threads with new activity (marked with ! or Y), you can open those in your default browser with lizard o (tip: have the browser running already before you do this).


1.1 (planned)

Important note: The database schema will change with this version. Backup your database and get ready to migrate.

0.4 (current)

Command syntax changes:

  • Listing threads:
    • lizard la (list all) will produce the previous lizard l functionality.
    • lizard l will list only items that have had something interesting happen (reply or 404).
    • lizard rl will print the summary list.

Tor features:

  • lizard tor will now auto-open the tor captcha page for convenience. (#42)
