What is blocky?

A standout opensource self-host project on GitHub — host on your own server for full control over your data and costs.

Main components

• Blocking - Blocking of DNS queries with external lists (Ad-block, malware) and allowlisting
• Definition of allow/denylists per client group (Kids, Smart home devices, etc.)
• Periodical reload of external allow/denylists
• Regex support
• Blocking of request domain, response CNAME (deep CNAME inspection) and response IP addresses (against IP lists)
• Advanced DNS configuration - not just an ad-blocker
• Custom DNS resolution for certain domain names
• Conditional forwarding to external DNS server

The biggest strength is active opensource community — fast bug fixes, regular features, no abandonment risk.

Best for self-host enthusiasts wanting to try a strong-community opensource project.
