AI agent development platforms provide frameworks, APIs, and runtime environments that allow developers to build, orchestrate, and deploy autonomous software agents. They are designed for software engineers, product teams, and AI researchers who need to equip models with memory, multi-step reasoning, and tool integrations. Unlike simple chatbot builders or basic prompting interfaces, these platforms deliver the deep backend infrastructure and routing needed for complex agentic workflows.
