Despite the ubiquity of APFS volumes in today's Macs and the format's 2016 introduction, third-party repair utilities continue to have notable limitations in supporting APFS volumes, due to Apple's delayed release of complete documentation. According to Alsoft, the maker of DiskWarrior, Apple's 2018 release of partial APFS format documentation has delayed the creation of a version of DiskWarrior that can safely rebuild APFS disks.<ref>{{cite web | url=https://www.alsoft.com/diskwarrior5apfs | title=DiskWarrior 5.2 & Apple File System (APFS) | access-date=2020-06-28}}</ref> Competing products, including MicroMat's TechTool and Prosoft's Drive Genius, are expected to increase APFS support as well.

[[Paragon Software Group]] has published a [[software development kit]] under the 4-Clause [[BSD License]] <!-- Not OSI approved, so not really open source? --> that supports read-only access of APFS drives.<ref>{{cite web |title=Paragon Software Group Releases Free Paragon APFS SDK Community Edition for Software Developers, OEMs, Forensic Experts |url=https://www.paragon-software.com/paragon-software-group-releases-free-paragon-apfs-sdk-community-edition-for-software-developers-oems-forensic-experts/ |website=Paragon Software Group}} [https://github.com/Paragon-Software-Group/paragon_apfs_sdk_ce GitHub]</ref> An independent read-only [[open source]] implementation by Joachim Metz, libfsapfs, is released under [[GNU Lesser General Public License]] v3.
