Its niche is not replacing curl for humans, but giving message-oriented systems a reusable, event-driven HTTP/WebSocket worker. ### Project history The project was started by Justin Karneges in 2012 and presented publicly by Fanout in 2014 as an HTTP/WebSocket client daemon for ZeroMQ architectures. Its design combines libcurl-based protocol handling with the ZHTTP message format, exposing request/response and streaming patterns over ZeroMQ sockets. ### Adoption history Zurl stayed a specialist component in the Fanout/Pushpin ecosystem rather than becoming a broad CLI utility. Its continued packaging matters because it preserves an older ZeroMQ service-composition style: small daemons connected by IPC or TCP sockets, with HTTP isolated as its own worker. ### How it is used Typical use is to run the daemon, connect a ZeroMQ REQ socket or the advanced PUSH/SUB streaming interface, and send JSON or TNetStrings requests describing HTTP methods, URIs, headers, body data, WebSocket messages, and policy flags. It is useful for webhook delivery, avoiding blocking outbound I/O in workers, sharing persistent connections, and allowing different processes to send requests and consume responses. ### Why package nerds care For package-nerd history, Zurl is a fossil from the moment when ZeroMQ was commonly used as application plumbing. It packages an architectural idea, HTTP as a durable message worker, that is now more often solved with language runtimes, queues, or service meshes. ### Timeline - 2012: Initial public git history begins for fanout/zurl. - 2014: Fanout publishes 'Fun with Zurl', framing it as a ZeroMQ gateway for outbound HTTP requests and WebSocket connections. - 2025: The repository still receives maintenance fixes, showing that the daemon remains buildable for its niche users. ### Related projects - Pushpin: Fanout/Fastly's realtime reverse proxy from the same ecosystem. - ZeroMQ and ZHTTP: the messaging layer and protocol abstraction that shape Zurl's interface. - libcurl: the HTTP implementation Zurl uses underneath. ### Sources - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** zurl - **Version Scheme:** 0 - **Revision:** 1 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - zurl - 1.12.0-3: normalized package name match | Debian stable package indexes: zurl from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | HTTP client worker with ZeroMQ interface | https://github.com/fanout/zurl/ - Ubuntu apt - zurl - 1.12.0-1ubuntu2: normalized package name match | Ubuntu 24.04 LTS package indexes: zurl from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | HTTP client worker with ZeroMQ interface | https://github.com/fanout/zurl/ ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [qtbase](https://www.automicvault.com/pkg/brew/qtbase/) - Runtime dependency declared by Homebrew. - [zeromq](https://www.automicvault.com/pkg/brew/zeromq/) - Runtime dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [pushpin](https://www.automicvault.com/pkg/brew/pushpin/) - Popular package that depends on this formula. - [bozohttpd](https://www.automicvault.com/pkg/brew/bozohttpd/) - Shares av.db curated category or tags: cli, daemon, http, networking. - [proxyfor](https://www.automicvault.com/pkg/brew/proxyfor/) - Shares av.db curated category or tags: cli, http, networking, websocket. - [whistle](https://www.automicvault.com/pkg/brew/whistle/) - Shares av.db curated category or tags: cli, http, networking, websocket. - [ahcpd](https://www.automicvault.com/pkg/brew/ahcpd/) - Shares av.db curated category or tags: cli, daemon, networking. - [argus](https://www.automicvault.com/pkg/brew/argus/) - Shares av.db curated category or tags: cli, daemon, networking. - [aria2](https://www.automicvault.com/pkg/brew/aria2/) - Shares av.db curated category or tags: cli, http, networking. - [axel](https://www.automicvault.com/pkg/brew/axel/) - Shares av.db curated category or tags: cli, http, networking. - [bombardier](https://www.automicvault.com/pkg/brew/bombardier/) - Shares av.db curated category or tags: cli, http, networking. - [zyre](https://www.automicvault.com/pkg/brew/zyre/) - Local package facts share a topical domain.
