history

Project history and usage

Zurl is a small Fanout-era networking daemon that turns outbound HTTP and WebSocket work into ZeroMQ messages. 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.
