About TmpDisk
TmpDisk creates RAM disks on macOS: volumes held in memory, which are much faster than a physical drive and are cleared when they are removed. It is useful for build caches, temporary files and other scratch data that benefits from fast reads and writes.
The project was created by Timothy Marks and is published and maintained by CosmicGlue. The repository includes a command-line tool alongside the app, and it is actively developed, with commits in September 2026.
