Project history and usage

blocky is a Go DNS proxy and ad blocker for local networks. It belongs to the self-hosted DNS-adblocking family, but its package identity is a single binary with YAML configuration, modern encrypted DNS protocols, metrics, and router/Raspberry Pi friendly deployment.

Project history

GitHub metadata dates blocky's repository to November 2019. The official README describes it as a fast, lightweight DNS proxy and ad blocker for local networks, written in Go, with blocking lists, allowlists, conditional forwarding, caching, DNSSEC-related features, Prometheus/Grafana integration, REST endpoints, and a CLI.

The README emphasizes simple operation: stateless behavior, no required database, Docker multi-arch images, a single binary, and support for x86-64, ARM, and MIPS. The docs describe YAML configuration, folder-based multi-file config merging, and generated JSON schema validation.

Adoption history

blocky's adoption tracks the home-network and homelab move from appliance-style ad blockers to packaged, containerized, and declarative DNS services. The input metadata records packages in Alpine apk, Homebrew, and Nix, while the README advertises Docker pulls and multi-architecture deployment.

The release stream is active: official releases include v0.32.1 on June 20, 2026, with several 0.30-plus releases earlier in 2026.

How it is used

Operators run blocky as a DNS service and configure upstream resolvers, blocklists, allowlists, ports, logging, privacy options, and protocol support in YAML. The official configuration docs explain `config.yaml`, `config.yml`, and using `--config` to point at a folder of `.yml` or `.yaml` files that are merged in lexical order.

Why package nerds care

blocky is interesting to package people because it packages an infrastructure service like a normal CLI: one Go binary, config schema, validation command, system-service-friendly behavior, and no mandatory database. That makes it easy to slot into Homebrew, Nix, Alpine, containers, routers, and homelab automation.

It also sits in the same practical category as Pi-hole and AdGuard Home while keeping a config-file-first shape that appeals to users who prefer declarative package-managed systems.
