history
Project history and usage
neon is a C library for HTTP/1.1 and WebDAV clients. Its README describes high-level HTTP/WebDAV methods, lower-level request handling, persistent connections, Basic and Digest authentication, Kerberos/SSPI/NTLM support, proxy support, TLS via OpenSSL or GnuTLS, WebDAV 207 XML handling, WebDAV locking/ACL support, and autoconf macros for embedding.
Project history
The official documentation carries a 2001-2026 Joe Orton copyright line, and the GitHub mirror/repository was created on 2019-03-07. The README states that neon's API and ABI keep backwards compatibility from 0.27 through 1.0.0, with semantic versioning intended from 1.0.0 onward.
Adoption history
neon mattered historically because it was an early Unix C library for WebDAV-heavy clients. Apache Subversion's WebDAV notes describe the Subversion client side interfacing with Neon to generate WebDAV requests, and cite Joe Orton of Neon among the HTTP library implementors involved in that ecosystem.
How it is used
Package users usually do not run neon directly except for neon-config; they install it because another source build or package needs the C library, headers, pkg-config/autoconf metadata, and TLS/XML dependencies. Homebrew packages it as a library with OpenSSL and libxml2 support, and the 2026-07-01 formula API snapshot reported 5,364 installs over 365 days, with 3,231 install-on-request events.
Why package nerds care
neon is a classic dependency package: quiet, old, and most visible when some WebDAV or legacy HTTP client still expects its ABI. For package databases, its history is more about downstream consumers and compatibility than about an end-user command.
