Maza ad blocking

A lightweight command‑line utility that blocks advertising and tracking domains by modifying the system’s hosts file and DNS resolution. It runs as a Bash script compatible with macOS, Linux, BSD and Windows Subsystem for Linux, allowing any browser or networked application to be filtered without installing extensions or separate services. Users can start, stop, update, and check the blocker with simple `sudo maza` commands, and the blocked domain list can be refreshed automatically via cron.

The tool ships with a default list of roughly 3,700 domains sourced from the Yoyo (Peter Lowe) hosts file, while also supporting alternative lists such as Steven Black’s larger collection. Custom blocklists and ignore rules are managed through plain‑text files in the user’s configuration directory, enabling fine‑grained control over which domains are filtered or exempted.

Maza is fully open source under the Apache‑2.0 license, self‑hostable, and requires only Bash 4.0+, curl, and optional GNU‑sed on macOS. Its design emphasizes native operation, minimal dependencies, and ease of installation through a single curl‑downloaded script.
