Executive Summary
AI Application Development Platforms enable developers to build, ship, and operate AI-native applications that combine generative capabilities with agentic behavior. These platforms go beyond model access or standalone code assistants to provide the runtime, tooling, and orchestration required to turn AI into production-grade applications.
This category reflects a shift in how software is built. Developers increasingly rely on AI not only to generate code, but also to reason, act, and coordinate tasks through agents. Modern AI applications integrate foundation models, tools, workflows, and memory into systems that can execute multi-step tasks, interact with external services, and adapt over time. AI Application Development Platforms provide the abstractions and controls needed to manage this complexity.
Unlike earlier cloud AI services focused primarily on APIs and infrastructure, these platforms are developer-centric and application-oriented. They support the full lifecycle, from code and agent creation to deployment, evaluation, governance, and runtime operations. As enterprises move from experimentation to scaled adoption, this category plays a central role in making generative and agentic AI reliable, secure, and operable.
This ShortList focuses on platforms that support both generative development and agentic systems, and that are designed to serve as the foundation for AI-powered products rather than isolated experiments.
