  v0.3.0 Stable

  "It now closes websites, not just programs."

  Added

  • Website blocking through a built-in DNS resolver on 127.0.0.1:53 and
    [::1]:53. One entry closes the domain and every subdomain under it —
    discord.com also covers gateway.discord.com, so there is no list to
    maintain by hand.
  • A "Sites" section in the panel: resolver status, query counters and a table of
    attempts, showing what was reached for and when.
  • A separate on/off switch for website blocking. Turning it off frees port 53
    and hands the adapters back to the router's settings.
  • Optional firewall rule that blocks queries to third-party name servers, so the
    resolver cannot simply be bypassed.
  • A --restore-dns switch that puts network settings back without starting the
    service, for the case where the service will not come up.

  Changed

  • Vue is compiled into the executable; it used to be fetched from unpkg.com.
    The panel now works without an internet connection, and a name resolution
    failure no longer takes away the only way to manage the service.
  • The uninstaller restores DNS settings before removing the service.

  Notes

  • Website blocking is off by default. Updates arrive on their own, without
    anyone at the keyboard, and must not silently rewrite network settings. Turn
    it on in the panel.
  • The resolver needs port 53. If something else holds it — Docker, Internet
    Connection Sharing, a third-party DNS proxy — the panel says so, network
    settings are left alone, and program blocking keeps working.
  • DNS over HTTPS in browsers and any VPN bypass this layer. Process termination
    is what covers those, whitelist mode most reliably.
  • Network settings are restored when the service stops. If that fails, it is
    recorded in the log under C:\ProgramData\SysHelper.
