# Pi-hole Pi-hole is a network-level Domain Name System (DNS) sinkhole that blocks Internet advertisements and tracking domains. It is open source and self-hosted, installable on Kubernetes (Helm), Proxmox, TrueNAS, Docker Hub, Umbrel, ZimaOS and Unraid. Canonical page: https://ourlocalhost.com/app/13/pi-hole ## Description Pi-hole is a network-level Domain Name System (DNS) sinkhole that blocks Internet advertisements and tracking domains. It serves DNS queries for a private network and can optionally provide Dynamic Host Configuration Protocol (DHCP) services to clients. It is intended for self-hosters who want centralized ad blocking for devices, media players, mobile apps, and browsers on their local network. Use it when you need a lightweight, Linux-based DNS solution that reduces unwanted network traffic and supports blocklists. ## Platform availability Available on 6 of 9 platforms: Unraid, TrueNAS, Umbrel, ZimaOS, Proxmox, Helm. ## Health score 78/100 (Good), based on 5 of 5 factors. - Maintained: 92 (last commit 109 days ago) - Popular: 96 (61,182 GitHub stars) - Easy to install: 70 (3 install platforms, install notes, setup guide, Docker image) - Light to run: 95 (512 MB minimum RAM, runs on ARM) - Security check: 20 (1 serious finding, 1 minor, CI, tests, OpenSSF Scorecard 6.2/10) ## Security check 1 serious finding: The app downloads a script and runs it in a shell at runtime.

Point your router's DHCP settings at Pi-hole so DHCP clients use it as their DNS server, or enable Pi-hole's optional DHCP server to assign it to devices. ### Can Pi-hole protect devices while they are on mobile data or public Wi-Fi? Pair it with a VPN such as WireGuard so your phone and laptop stay protected on mobile data and public Wi-Fi. ### Can I deploy Pi-hole in Docker? Pi-hole can run in a Docker container, and the README points to the official Docker images for deployment. ### Does Pi-hole have an API for scripting or automation? It provides a full REST API with built-in documentation for scripting and extending everything. ### What should I check first if Pi-hole is not working? Make sure all dependencies are installed, including updated packages, and that the DNS server is running. ## Alternatives - AdAway: An ad blocker that uses the hosts file. - AdGuard: AdGuard is the best way to get rid of intrusive ads and online tracking, and to protect your computer from malware. - AdGuard Home: AdGuard Home is a self-hosted DNS server that blocks ads and trackers across your entire home network by re-routing tracking domains to a b… - Blokada: Blokada is the popular ad blocker and privacy app for Android and iOS. - Control D: Control D is a modern and customizable DNS service that blocks threats, unwanted content and ads - on all devices. - NextDNS: NextDNS protects you from all kinds of security threats, blocks ads and trackers on websites and in apps and provides a safe and supervised… - OpenSnitch: Firewall for Linux providing interactive outbound filtering, blocking ads and malware domains, configurable via GUI, with centralized node… - Portmaster: Free and open-source tool that monitors all network activity, blocks unwanted connections, uses filter lists for ads and malware, enforces… - Privoxy: Privoxy is a non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, co… - RethinkDNS: An OpenSnitch-inspired firewall and network monitor + a pi-hole-inspired DNS over HTTPS client with blocklists. - Technitium DNS Server: Technitium DNS Server is an open source tool that can be used as a personal local DNS server for privacy & security. - simplewall: Simple tool to configure Windows Filtering Platform (WFP) which can configure network activity on your computer. --- Source: Our Local Host (https://ourlocalhost.com/app/13/pi-hole), the self-hosted and open-source app directory.
