One Platform, Everything Included
The AI agent infrastructure landscape is fragmented. You need a runtime, a database, a queue, an email service, a scheduler, monitoring — and then you need them to work together. Cloudflare’s answer: build all of it into one platform.
Cloudflare Agents launched as a TypeScript SDK where each agent runs on a Durable Object — a stateful micro-server with its own SQL database, WebSocket connections, and scheduling capabilities, deployed across Cloudflare’s global network of 330+ cities.
What You Can Build
The platform covers the full agent lifecycle: streaming AI chat, server-side and client-side tools, human-in-the-loop approval flows, and task scheduling. The starter template uses Workers AI by default with no API keys required, but you can call any model — Workers AI, OpenAI, Anthropic, Gemini — and stream responses over WebSockets or Server-Sent Events.
The Email Service (private beta since November 2025) is the missing piece most agent platforms ignore. Transactional email directly from Workers means your agent can send confirmation emails, weekly digests, or alert notifications without an external email provider. Email Sending joins Email Routing to form a unified email developer experience.
Agents can also integrate with Slack, Discord, email, or any messaging platform — both receiving and sending messages proactively.
March 2026 Updates
Workers AI now runs large models starting with Kimi K2.5, expanding beyond the smaller models that defined its first two years. Plus: AI Security for Apps, a dedicated security layer for autonomous AI agents, addressing the growing attack surface as agents gain more autonomy.
What’s Missing
The Email Service is still in private beta — you need to request access. The TypeScript-only SDK limits teams using Python. And the Durable Objects pricing model can be hard to predict at scale compared to fixed-rate alternatives.
The Verdict
Cloudflare Agents is the most complete AI agent platform available if you’re building in TypeScript. The combination of durable execution, built-in email, global edge deployment, and model-agnostic inference in a single platform is unmatched. The bet is that serverless agents — not long-running VMs — are the future of AI infrastructure. If that bet is right, Cloudflare is two years ahead.
