ActRecipe
ActRecipe Inc.
ActRecipe is an iPaaS that enables you to integrate data from SaaS and FinTech services and strengthen internal controls by simply selecting recipes. Even in the case of complex integration, our consultants will prepare the best recipe for you, so there is no need for users to learn tools or share advanced IT knowledge. iPaaS (integration platform-as-a-service), also called "cloud integration platform", is a platform for building and deploying corporate data integration in real time on the cloud. Due to the rapid progress in the use of cloud services according to usage, corporate data is scattered in all services, and the integration of that data is becoming more complicated day by day. iPaaS can be used to optimize business processes and reduce total costs by enabling data linkage between SaaS and cloud services to be expanded or reduced according to needs. Since all linkages between the cloud and other systems are done manually, the risk of tampering remains. -

Tornado Web Server
Tornado
Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. Tornado is different from most Python web frameworks. It is not based on WSGI, and it is typically run with only one thread per process. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written to use Tornado’s own interfaces (such as tornado.web) directly instead of using WSGI. In general, Tornado code is not thread-safe. Tornado is integrated with the standard library asyncio module and shares the same event loop (by default since Tornado 5.0). In general, libraries designed for use with asyncio can be mixed freely with Tornado. -

SpiraCapture
inflectra
SpiraCapture™ is a browser extension that helps you carry out exploratory testing. The extension intelligently records and organises your testing sessions and lets you save your recordings seamlessly into SpiraTest. Cem Kaner, who coined the term Exploratory Testing, described it as "a style of software testing that emphasizes the personal freedom and responsibility of the individual tester.” During this freeform, intuitive approach to testing, the testing steps and path are not predefined and have to be manually captured. The flow and steps of a testing session are important for effective communication between testers and developers. At Inflectra, we strive to make this communication faster and easier with SpiraCapture. There are times when you want to know exactly what you did to produce a problem in an application under test. What sequence of clicks or url changes got the app into that weird state? By recording everything significant that the tester does, automatically. -
