At the AWS re:Invent 2025 conference in Las Vegas, Amazon Web Services (AWS) unveiled a trio of AI-powered tools called frontier agents, representing a significant step toward more autonomous software development and operations. These agents are designed to work independently for hours or even days without requiring human intervention, automating crucial but time-consuming tasks surrounding code creation, repository management, DevOps processes, and cybersecurity monitoring. According to AWS, the frontier agents aim to relieve programmers from the manual oversight often needed when using AI coding tools, thus allowing developers to focus more on higher-level tasks.

The three AI agents introduced are the Kiro Autonomous Agent, AWS Security Agent, and AWS DevOps Agent. The Kiro agent functions much like a virtual developer, intelligently managing context and code repositories while continuously learning from pull requests and feedback. It performs diverse tasks, from triaging bugs to improving code coverage, and can coordinate changes across multiple repositories. AWS describes Kiro as capable of maintaining persistent context across sessions, making it a sophisticated assistant that integrates seamlessly into a developer’s workflow.

The AWS Security Agent acts as a virtual security engineer, designed to ensure compliance with an organisation’s security standards within both design documents and code pull requests. It automates penetration testing, a process of identifying vulnerabilities by simulating attacks, much faster and at a larger scale than manual methods. This agent can perform simultaneous tests across multiple applications, enhancing security oversight and reducing risks before code reaches production.

Meanwhile, the AWS DevOps Agent takes on the role of an operations team member by automatically conducting root cause analyses when application issues arise in production environments. It learns from a broad range of resources, including observability tools such as Amazon CloudWatch, third-party monitoring platforms like Datadog, Dynatrace, and Splunk, as well as runbooks, code repositories, and continuous integration and delivery (CI/CD) pipelines. The agent not only helps resolve incidents but also supports proactive measures to improve application reliability and performance over time.

Amazon has made the Kiro agent accessible to developers via a dedicated site, while the Security and DevOps agents can be accessed through the AWS management console. The company positions these frontier agents as autonomous team members capable of running multiple tasks in parallel and for extended periods without direct supervision, which could mark a shift from AI as a tool to AI as a collaborator in software development.

This move positions AWS in a highly competitive market where numerous vendors, including longtime partners and rivals, are developing AI-driven automation solutions targeting the entire software development lifecycle. For example, DevOps platforms such as Cisco's Splunk, Datadog, and Dynatrace have offered AI-powered automations that accelerate coding, testing, debugging, deployment, and monitoring, aiming to identify vulnerabilities early. Similarly, GitLab competes with Microsoft's GitHub by introducing AI agents to reconcile code changes automatically, with recent integrations between GitLab’s Duo Agent and AWS’s generative AI assistant, Q Developer, illustrating the convergence of these technologies. On the cybersecurity front, firms like Palo Alto Networks focus on automating authentication and security alerting processes relevant to code integrity.

Beyond the frontier agents themselves, AWS is doubling down on infrastructure to support AI agents with the introduction of Amazon Bedrock AgentCore, a platform announced at the AWS Summit in New York. Bedrock AgentCore is geared toward developers looking to build, deploy, and manage AI agents more easily, offering modular components for secure deployment environments, memory handling, identity management, network interoperability, and observability tools for debugging and monitoring agent performance. This platform is designed to transform AI agents from experimental tools into reliable, production-ready software collaborators.

Swami Sivasubramanian, AWS Vice President for Agentic AI, described this development as a "tectonic change," equating the rise of AI agents to the transformative impact of the internet's emergence. According to him, these agents will redefine how software is built and interacted with, ushering in new levels of innovation and productivity across industries.

While technical details remain sparse on how exactly these frontier agents operate autonomously for extended periods, Amazon stresses their ability to handle complex, goal-driven tasks without ongoing human supervision, indicating a potential evolution in software workflows. For enterprises grappling with increasing complexity in DevOps, coding, and cybersecurity, these advancements could be a pivotal step toward more efficient and resilient application development, though competition remains fierce as multiple vendors race to lead the market in AI-powered software agents.
