  • inter-process communication (needed for X11)
    --share=ipc
  • network
    --share=network

Who publishes this

Nobody has confirmed that the publisher controls this app id. Flatsonar warns before installing.

  • net.lesderid.Showdown claims the domain lesderid.net; only its owner can prove that
    publisher:namespace
  • fetches from github.com over unencrypted git: anyone on the path can swap the bytes
    source:insecure-url
  • git source tracks a moving branch: what gets built can change without the manifest changing
    source:unpinned
