Jackett
API Support for your favorite torrent trackers
Jackett works as a proxy server, it translates queries from apps (Sonarr, Radarr, SickRage, CouchPotato, Mylar3, Lidarr, DuckieTV, qBittorrent, Nefarious, etc.) into tracker-site-specific HTTP queries, parses the HTML or JSON response, and then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic, removing the burden from other apps. Trackers marked with (invite needed) have no active maintainer and may be missing features or be broken. If your client supports multiple feeds it's recommended to add each indexer directly instead of using all indexers. Using the all indexer has no advantages (besides reduced management overhead). We recommend you install Jackett as a Windows service using the supplied installer. You may also download the zipped version if you would like to configure everything manually. -

Service Bus Explorer
Connect to a Service Bus namespace and administer messaging entities
The Service Bus Explorer allows users to connect to a Service Bus namespace and administer messaging entities in an easy manner. The tool provides advanced features like import/export functionality or the ability to test topics, queues, subscriptions, relay services, notification hubs, and events hubs. Microsoft Azure Service Bus is a reliable information delivery service. The purpose of this service is to make communication easier. When two or more parties want to exchange information, they need a communication facilitator. Service Bus is a brokered, or third-party communication mechanism. This is similar to postal service in the physical world. Postal services make it very easy to send different kinds of letters and packages with a variety of delivery guarantees, anywhere in the world. The Service Bus Explorer 2.1.0 can be used with the Service Bus for Windows Server 1.1. The Service Bus Explorer 2.1.0 uses a version of the Microsoft.ServiceBus.dll client library. -

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. -
