Supports macOS, Linux and Windows.
Standalone executables for Linux, macOS and Windows.

⚠️ Warning: Performances
mdedup implementation is quite naive at the moment and everything resides in memory.
If this is good enough for a volume of a couple of gigabytes, the more emails mdedup try to parse, the closer you'll reach the memory limits of your machine. In which case mdedup will exit abrubtly, zapped by the OOM killer of your OS. Of course your mileage may vary depending on your hardware.
You can influence implementation of this feature with pull requests, or purchase of business support 🤝 and sponsorship 🫶.
