    ownCloud

    ownCloud

    ownCloud web server core (Files, DAV, etc.)

    ownCloud Core is the foundational server component of the ownCloud ecosystem, providing a self-hosted platform for secure file storage, synchronization, and sharing across devices and teams. It enables organizations and individuals to maintain full control over their data by running a personal cloud on their own infrastructure rather than relying on third-party providers. The software supports collaborative workflows by allowing users to upload, organize, and share files through a web interface, desktop sync clients, and mobile integrations. Designed with extensibility in mind, the core platform can be enhanced through apps and plugins that add capabilities such as document editing, authentication methods, and workflow automation. It is widely used in enterprise and privacy-focused environments because it combines open-source transparency with enterprise-grade controls and permissions.

    Kinto

    Kinto

    A generic JSON document store with sharing and synchronisation options

    Kinto is a minimalist JSON storage service with synchronization and sharing abilities. It is meant to be easy to use and easy to self-host. Kinto is used at Mozilla and released under the Apache v2 license. It’s hard for frontend developers to respect users' privacy when building applications that work offline, store data remotely and synchronize across devices. Existing solutions either rely on big corporations that crave user data or require a non-trivial amount of time and expertise to set up a new server for every new project. We want to help developers focus on the front, and we don’t want the challenge of storing user data to get in their way. The path between a new idea and deploying to production should be short! Also, we believe data belong to the users, and not necessarily to the application authors. Applications should be decoupled from the storage location, and users should be able to choose where their personal data are stored.

    SparkleShare

    SparkleShare

    Share and collaborate by syncing with any Git repository

    SparkleShare creates a special folder on your computer. You can add remotely hosted folders (or "projects") to this folder. These projects will be automatically kept in sync with both the host and all of your peers when someone adds, removes or edits a file. SparkleShare was made to cover certain use cases, but doesn't handle every scenario well. SparkleShare uses the version control system Git under the hood, so setting up a host yourself is relatively easy. Using your own host gives you more privacy and control, as well as lots of cheap storage space and higher transfer speeds. The idea of SparkleShare sprouted at the GNOME Usability Hackfest in London, where a couple of designers came to the conclusion that they didn't have a good (Open Source) collaboration tool to share their work.

    Lotus Notes to Google Calendar tool

    Lotus Notes to Google Calendar tool

    One-way synchronization from Lotus Notes Calendar to Google Calendar

    This is a one-way sync program that will sync your Lotus Notes Calendar to your Google Calendar. No installation is required. Includes many options such as automatic syncing at specified intervals. *Important Privacy Information: https://sourceforge.net/p/lntogoogle/wiki/PrivacyPolicy/ *** Information Update, September 2020: *** Recent issues with Google Synchronization should be fixed with version 1.9.2 which is available for download, now. For typical installation pitfalls, see: https://sourceforge.net/p/lntogoogle/wiki/InstallationPitfalls/ The project was not maintained since its last update in February 2015. However, since I've tracked more than 15.000 Downloads over the last 5 years and still more than 1 million Calendar API-Calls per day, I assume that the tool is still very much in use. So I decided to go back to work. More info: https://sourceforge.net/p/lntogoogle/wiki/Home/ Donations appreciated

    SyncManager

    SyncManager

    Sync manager that helps you sync your files across different locations

    SyncManager is a custom-made lightweight synchronization manager that helps you synchronize files and folders across different locations. SyncManager lets you synchronize your data in two ways: manually or automatically. Manual syncing mode lets you decide what and when to synchronize data, while automatic syncing mode synchronizes data based on its average synchronization time. It also offers three distinct synchronization types: two-way, one-way, and one-way update, allowing you to synchronize data between folders in different ways. Plus, it has filtering and customizable versioning settings that help you to set synchronization more precisely. You can also decide how to handle old versions of files and folders: move them to the trash, delete them permanently, or version them in a special folder. The utility is operating as a fully automated solution that seamlessly launches at system startup.
