Editorial classification
Strong managed agent platforms — real hosted runtime, not just SDK/framework
Ecosystem / tooling / runtime — important but not a single hosted harness
Claude Managed Agents
The reference point. Hosted agent harness / infrastructure for long-running autonomous tasks. Includes managed runtime, tool access, sandboxing, and full agent loop. When evaluating other platforms, the question is: does this offer a comparable hosted, operable agent environment?
Agents SDK · Agent Builder · Responses API
Framework and API-first rather than a single managed agent harness. Agents SDK covers orchestration patterns, tool use, tracing, and runtime; Agent Builder adds visual workflow building. Very important ecosystem — not a one-to-one hosted runtime equivalent in the Anthropic sense, but the tooling layer is comprehensive.
Gemini Enterprise Agent Platform · Vertex AI Agent Builder · ADK
Positioned for building, scaling, governing, and optimising agents in production. Agent Development Kit (ADK) handles build / debug / deploy. The agent platform specifically addresses the enterprise governance and optimisation layer beyond the model API. Strong build-scale-govern story.
Microsoft Foundry Agent Service · Microsoft Agent 365 · Agent Framework
Split across build and governance. Foundry Agent Service is a fully managed platform for building, deploying, and scaling agents. Agent 365 operates as an enterprise control plane — governing agents across an organisation rather than running them directly. Addresses two different buyer personas in one portfolio.
Amazon Bedrock Agents · Bedrock AgentCore
Bedrock Agents handles creating and configuring autonomous agents; AgentCore is the newer platform layer for building, deploying, and operating agents securely at scale. AWS docs now position AgentCore as the forward path. Two complementary layers: orchestration config (Agents) and runtime operations (AgentCore).
Mistral Agents · Vibe Code Web
API-level agents and tools. Vibe Code Web extends this to remote coding agents running in managed cloud sandboxes. Partial equivalent — meaningful infrastructure exists but not a general-purpose hosted agent harness at the same scope as top-tier platforms.
Tool use / function calling
Supports agentic workflows via tool use, multi-step reasoning, and citations. No direct managed-agent runtime equivalent found. Relevant for enterprise retrieval and RAG workflows where agentic patterns are secondary to document processing.
Build agents on Databricks · Agent Framework · Supervisor Agent · Agent tools
Tooling for building, deploying, managing, tracing, evaluating, and orchestrating AI agents — particularly strong for data and GenAI apps. Supervisor Agent pattern enables multi-agent orchestration. Relevant when the agent's primary function is operating on enterprise data assets within Databricks' lakehouse.
Cortex Agents · Cortex Agents REST API · Monitor Cortex Agent requests
Cortex Agents orchestrate across structured and unstructured data using Cortex Analyst and Cortex Search. REST API for creation and management, plus monitoring and tracing. Strong enterprise data agent story — purpose-built for the Snowflake data cloud perimeter.
Cloudflare Agents SDK · Workers AI · Docs for agents
Stateful agents running on Durable Objects with persistent state, WebSockets, scheduling, tool access, MCP support, and global deployment. Infrastructure-first angle — the managed layer is Cloudflare's edge runtime rather than a model-provider platform. Best-in-class if agent runtime infrastructure and latency matter.
OCI Generative AI Agents · AI Agent Studio for Fusion Apps · Enterprise AI agents
OCI Generative AI Agents is described as a fully managed service. AI Agent Studio targets Fusion application-specific agents. Enterprise-app focused — the strongest fit is Oracle customers deploying agents within the ERP / CX stack rather than general-purpose agent deployment.
Vercel Agent · AI SDK · Agent Resources · AI Gateway · MCP
Significant agent infrastructure spread across multiple layers: AI SDK, Gateway, MCP, agent skills and resources, marketplace agents, and the Vercel Agent for development workflows. Not a single Claude Managed Agents-style general hosted runtime — more of a developer-infrastructure-for-AI platform. Relevant for web app deployment and AI app infrastructure use cases.
Copilot cloud agent · Agent management · Custom agents · Third-party agents
GitHub Copilot cloud agent is a managed autonomous coding agent that operates inside GitHub — creates branches, raises pull requests, manages sessions, and operates under configurable policies. Fully managed, coding-specific. The best example of a tightly scoped managed agent in production at scale.
AI Agent node · AI Agent Tool node · Plan and Execute Agent
Workflow automation platform with agent nodes, tool support, approvals, and multi-agent orchestration patterns. Not a hyperscaler-style managed LLM agent runtime — it sits at the workflow coordination layer. Relevant for teams who want agentic behaviour inside existing automation infrastructure without switching to a model-provider runtime.
