CAST Reviews, Ratings & Features 2026 | Gartner Peer Insights

Green software engineering is the discipline of building sustainable software that is carbon-efficient and carbon-aware. Carbon efficiency aims to reduce carbon emissions throughout the software development life cycle. Carbon awareness involves optimizing software to utilize low-carbon energy sources. Building green software involves making energy-efficient choices in architecture and design patterns, algorithms, data structures, programming languages, language runtimes and infrastructure. This leads to lower operational costs, improved performance, and alignment with organizational sustainability goals. The benefits extend to developers, architects, product teams, and enterprises committed to ESG standards, while end users gain faster, more efficient applications. Ultimately, green software engineering helps organizations create resilient, high performing systems that minimize environmental impact without compromising functionality.

Mission-critical, custom-built applications are becoming incredibly difficult to adapt to the ever-evolving needs of the business, to the point where it’s hardly possible for humans to keep up. 
CAST technology automatically ‘understands’ custom-built software systems and provides insights into their inner workings, with MRI-like precision. It augments the human capacity to help software owners maintain, enhance, modernize these applications with speed and confidence.
Resulting from well over $200 million of R&D, CAST software is used and promoted by hundreds of companies, top management consultancies, the 10 largest system integrators, and all three major cloud vendors.

CAST, the software intelligence leader, provides software that ‚Äòunderstands‚Äô multi-technology software systems and automatically derives insights about their inner workings ‚Äì interactions between all its elements, transaction flows, data access paths, changes needed to move to cloud, open-source risks, green impact, ISO 5055 compliance, etc. It is used globally by thousands of digital leaders, helping them make smarter decisions, maintain and transform custom software with greater speed, and exert better ongoing control of the risks involved.
