Welcome to the Chocolatey Community Package Repository! The packages found in this section of the site are provided, maintained, and moderated by the community.
Every version of each package undergoes a rigorous moderation process before it goes live that typically includes:
- Security, consistency, and quality checking
- Installation testing
- Virus checking through VirusTotal
- Human moderators who give final review and sign off
If you are an organization using Chocolatey, we want your experience to be fully reliable. Due to the nature of this publicly offered repository, reliability cannot be guaranteed. Packages offered here are subject to distribution rights, which means they may need to reach out further to the internet to the official locations to download files at runtime.
Fortunately, distribution rights do not apply for internal use. With any edition of Chocolatey (including the free open source edition), you can host your own packages and cache or internalize existing community packages.
Your use of the packages on this site means you understand they are not supported or guaranteed in any way. Learn more...

To edit the metadata for a package, please upload an updated version of the package.
Chocolatey's Community Package Repository currently does not allow updating package metadata on the website. This helps ensure that the package itself (and the source used to build the package) remains the one true source of package metadata.
This does require that you increment the package version.

Duplicacy is a new generation cross-platform cloud backup tool based on the idea of Lock-Free Deduplication.
This repository hosts source code, design documents, and binary releases of the command line version of Duplicacy. There is also a Duplicacy GUI frontend built for Windows and Mac OS X available from https://duplicacy.com.
There is a special edition of Duplicacy developed for VMware vSphere (ESXi) named Vertical Backup that can back up virtual machine files on ESXi to local drives, network or cloud storages.
There are 3 core advantages of Duplicacy over any other open-source or commercial backup tools:
Duplicacy is the only cloud backup tool that allows multiple computers to back up to the same cloud storage, taking advantage of cross-computer deduplication whenever possible, without direct communication among them. This feature literally turns any cloud storage server supporting only a basic set of file operations into a sophisticated deduplication-aware server.
Unlike other chunk-based backup tools where chunks are grouped into pack files and a chunk database is used to track which chunks are stored inside each pack file, Duplicacy takes a database-less approach where every chunk is saved independently using its hash as the file name to facilitate quick lookups. The lack of a centralized chunk database not only makes the implementation less error-prone, but also produces a highly maintainable piece of software with plenty of room for development of new features and usability enhancements.
Duplicacy is fast. While the performance wasn't the top-priority design goal, Duplicacy has been shown to outperform other backup tools by a considerable margin, as indicated by the following results obtained from a benchmarking experiment backing up the Linux code base using Duplicacy and 3 other open-source backup tools.
Duplicacy currently provides the following storage backends:
- Local disk
- Amazon S3
- DigitalOcean Spaces
- Google Cloud Storage
- Microsoft Azure
- Backblaze B2
- Google Drive
- Microsoft OneDrive
- OpenStack Swift
- WebDAV (under beta testing)
- pcloud (via WebDAV)
- Box.com (via WebDAV)
Please consult the wiki page on how to set up Duplicacy to work with each cloud storage.
For reference, the following chart shows the running times (in seconds) of backing up the Linux code base to each of those supported storages:

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
Chocolatey Pro provides runtime protection from possible malware.
