KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file.

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. -

Selenium
Browser automation framework and ecosystem
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

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. -
