SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases.
The product family is composed of:
- An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses.
- A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time.
- PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser;
- The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.

JOpt.TourOptimizer is an enterprise optimization engine for route planning, scheduling, and resource allocation across logistics, transportation, dispatch, and field service operations. It is built for organizations that need to solve complex planning problems under real-world business constraints rather than simple consumer-grade route calculation. The platform supports vehicle routing and scheduling scenarios such as VRP, CVRP, VRPTW, pickup and delivery, multi-depot planning, heterogeneous fleets, and workforce scheduling.
JOpt.TourOptimizer can model time windows, working hours, visit durations, capacities, skills and expertise levels, territories, zone governance, overnight stays, alternate destinations, and custom business rules. This makes it suitable for production deployments where feasibility, transparency, and operational reliability matter. It is designed to generate practical plans that help teams balance travel time, service commitments, workload distribution, and operational cost in demanding enterprise environments.
The solution is available both as an embedded Java SDK and as a Docker-based REST API with OpenAPI and Swagger support. This allows software vendors, enterprise developers, and system integrators to embed advanced optimization into TMS, ERP, CRM, WMS, dispatch systems, customer platforms, and field service applications. With support for scalable integration and modern service architectures, JOpt.TourOptimizer helps organizations improve planning efficiency, service quality, SLA compliance, transparency, and operational resilience at scale. It also supports enterprise integration strategies that require reproducible optimization runs, structured outputs, and flexible deployment models.

Material Design Lite
Material Design Lite (MDL) serves as a collection of components tailored for web developers, inspired by Google's Material Design Philosophy, which emphasizes a visual language that merges classic design principles with the advancements of technology and science. Grasping the objectives and foundations of Material Design is essential for effectively implementing MDL components. Prior to utilizing these components, it is advisable to familiarize yourself with the Material Design Introduction. When it comes to the dialog component, ensure you are operating in a browser that accommodates the dialog element; as of now, only Chrome and Opera provide native support. For browsers lacking this capability, you will need to either incorporate the dialog polyfill or devise your own solution. After securing dialog support, proceed to create a dialog element, ensuring that when using the polyfill, this element is nested within the body element. Subsequently, within this container, insert a content element that includes the class mdl-dialog content to properly format the dialog. Understanding these steps will enhance your ability to successfully implement dialogs within your web projects.
