SurveyJS
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
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.

Grape Ripeness Logger
Mio Vigneto Products is excited to introduce the Grape Ripeness Logger, marking the initial release in a line of affordable software solutions designed to assist Vineyard Managers and Winemakers in improving the quality of their wines. This innovative software facilitates the meticulous recording and organization of vineyard data by year, grape variety, and specific blocks, ensuring that users have reliable historical records. The interface of the Grape Ripeness Logger is optimized for both tablets and desktop computers, enabling seamless data entry in the field as measurements for grape sugar, TA, and pH are taken. Users can easily input vineyard ownership information and create a structured directory based on vineyard names, while subdirectories categorize entries by grape variety and sampling locations. Additionally, the Grape Data screen enables the input of key metrics like Brix, pH, and TA, which subsequently computes the Balance and Ripeness of the grapes. All collected data is conveniently displayed and stored in a user-friendly spreadsheet format. Furthermore, users can also determine the ideal "Harvest Date" based on their target Brix, pH, and TA levels, which enhances planning and decision-making for the harvest season. This tool is poised to offer invaluable support to the wine industry, simplifying the management process for both current and future vintages.
