Build Website License

Improve your security and privacy by blocking ads, tracking and malware domains.

Table of contents

What is this for?

This POSIX-compliant shell script, designed for Unix-like systems, gets a list of domains that serve ads, tracking scripts and malware from multiple sources and creates a hosts file (alternative formats are also supported) that prevents your system from connecting to them.

Is it safe to use?

Absolutely, this script selects only the domain names for each source, so if a domain name is redirected to a rogue server your system will not be affected. In the worst scenario you can lose access to a legitimate domain name due a false positive, but you can reverse it by adding that domain to the whitelist.

Nightly builds

I provide nightly builds of the hosts file and other formats, including installers for Windows (batch file) and Android (flashable zip).




curl -o /tmp/hblock 'https://raw.githubusercontent.com/hectorm/hblock/v2.1.6/hblock' \
  && echo '9e22c32c8ae4d93df18a41f08d31e8668ef4342fda82ca91ec4aa47f718fdadc  /tmp/hblock' | shasum -c \
  && sudo mv /tmp/hblock /usr/local/bin/hblock \
  && sudo chown root:root /usr/local/bin/hblock \
  && sudo chmod 755 /usr/local/bin/hblock

Note: you can use this Systemd timer to regularly update the hosts file for new additions.

Optionally, it is possible to use NPX to run hBlock without installation

npx hblock


Add the src_prepare overlay with the help of the official repository.

Unmask the net-firewall/hblock package with the help of the Gentoo wiki.


emerge --verbose net-firewall/hblock
