- Standalone
curl
tool andlibcurl
DLL. Static libraries included. - Required: Windows Vista with Universal CRT (64-bit ARM or Intel), macOS 10.9 Mavericks (ARM or Intel), Linux kernel 2.6.39+ (amd64, arm64, RISC-V 64) with MUSL builds.
- HTTP/3, HTTP/2 support, and more.
- Windows 64-bit builds are Control Flow Guard enabled. Intel builds have CET enabled. All builds have frame pointers enabled.
- Transparent builds, using open source code, run in public, with auditable logs.
- LLVM/Clang build environment with
mingw-w64
via Debian, Homebrew, MSYS2.llvm-mingw
for ARM64. - Windows cross-built and published via
AppVeyor CI. Linux built via GHA.
Using reproducible container image
debian:testing-slim
via rootless podman. macOS built via GHA. - Linux and macOS builds are not official curl builds.
- We verify components using SHA-256, and PGP where provided.
- We build reproducible binaries, producing the same hash given the same input sources and C compiler.
- Patching policy: No local patches. We may apply patches if already merged upstream or — for showstoppers — had them submitted with fair confidence of getting merged.
- You can look up our package hashes in lines starting with
SHA
in the build log. - Packages built across host platforms do not have identical hashes due to
slightly different build options and toolchain builds/versions. Except
llvm-mingw
builds used for ARM64, which are reproducible across platforms. - We code-sign with a self-signed certificate on Windows, and avoid trusted timestamps for reproducibility.
Uses LibreSSL TLS backend.
