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.

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.

Livewire
Livewire is a comprehensive framework designed for Laravel that streamlines the creation of dynamic interfaces while allowing developers to remain within the familiar Laravel environment. It empowers developers to construct modern, reactive web applications by utilizing Laravel's Blade templating engine, thereby removing the necessity for an independent frontend framework. Through a global event system, Livewire components can easily communicate with one another, facilitating smooth interactions among components present on the same page. The framework is equipped with features such as data binding, validation, and lifecycle hooks, which simplify the process of developing intricate, dynamic interfaces. By managing frontend interactions server-side, Livewire minimizes the complexity often associated with building dynamic user interfaces, enabling developers to concentrate on application logic without the need for extensive JavaScript. Moreover, Livewire initially renders the component output alongside the page, contributing to its SEO-friendly nature. Upon user interaction, Livewire promptly sends an AJAX request to the server with any updated information, ensuring a seamless user experience. This unique approach allows for a more efficient development process, merging backend capabilities with frontend responsiveness.
