Use the links below to download the Apache Portable Runtime from one of our mirrors. You must verify the integrity of the downloaded files using signatures downloaded from our main distribution directory.

Only current recommended releases are available on the main distribution site and its mirrors. Older releases are available from the archive download site.

Mirror

The currently selected mirror is https://dlcdn.apache.org/. If you encounter a problem with this mirror, please select another mirror. If all mirrors are failing, there are backup mirrors (at the end of the mirrors list) that should be available. Other mirrors: https://dlcdn.apache.org/https://dlcdn.apache.org/ (backup) You may also consult the complete list of mirrors.

APR 1.7.5 is the best available version

APR is the base portability library. Unix Source: apr-1.7.5.tar.gz [PGP] [SHA256] Unix Source: apr-1.7.5.tar.bz2 [PGP] [SHA256] Win32 Source: apr-1.7.5-win32-src.zip [PGP] [SHA256] Other files

APR-util 1.6.3 is the best available version

APR-util provides a number of helpful abstractions on top of APR. Unix Source: apr-util-1.6.3.tar.gz [PGP] [SHA256] Unix Source: apr-util-1.6.3.tar.bz2 [PGP] [SHA256] Windows Source: apr-util-1.6.3-win32-src.zip [PGP] [SHA256] Other files

APR iconv 1.2.2 is the best available version

APR-iconv provides a portable iconv() implementation built on top of APR. It is generally of interest only where no system provided iconv() is available (either in libiconv, or libc as applicable). An example is the Windows platform, where APR-iconv is required to enable the APR-util library's apr_xlate feature. Unix Source: apr-iconv-1.2.2.tar.gz [PGP] [SHA256] Unix Source: apr-iconv-1.2.2.tar.bz2 [PGP] [SHA256] Windows Source: apr-iconv-1.2.2-win32-src.zip [PGP] [SHA256] Other files

Verify the integrity of the files

It is essential that you verify the integrity of the downloaded files using the PGP signatures, using a tool such as GnuPG (GPG). Please read Verifying Apache HTTP Server Releases for more information on how and why you must verify our releases The same rationale applies to APR as to HTTP Server). PGP public keys for individual Apache developers can be downloaded (and fingerprints verified) at https://people.apache.org/keys/committer/. Alternatively, keys for APR developers are available in a bundle at https://people.apache.org/keys/group/apr.asc.
