If you’ve been waiting for a real, production-grade platform to run long-lived AI agents — not toy demos, but agents that can clone repositories, install dependencies, execute multi-step tasks across sessions, and actually persist state — Cloudflare just made a major move in that direction.

This week, Cloudflare officially kicked off Agents Week, a dedicated event showcasing a significant expansion of its Agent Cloud platform. The headline announcements: persistent Linux Sandboxes are now generally available, and Think, a new Agents SDK framework purpose-built for long-running, multi-step agent workflows, is shipping alongside it.

What Is Cloudflare Agent Cloud?

Cloudflare has been quietly building out infrastructure specifically for AI agents — not just serving LLM inference, but actually running agents as first-class workloads. The vision is a cloud that was designed for the age of AI, not retrofitted from the smartphone era.

The Agent Cloud platform treats agents as persistent, long-running workers. They can hold state, call tools, and — with today’s announcements — run full Linux environments across sessions.

GA: Persistent Linux Sandboxes

This is the big one. Cloudflare’s persistent Linux Sandboxes are now generally available. What does that mean in practice?

  • Clone and run actual repositories — agents can git clone, install packages with pip or npm, and execute build processes
  • Multi-session persistence — state survives across agent invocations. A sandbox isn’t torn down after a single run
  • Secure execution — code runs in isolated environments, so you’re not giving agents unrestricted access to your infrastructure
  • Builds and CI-style tasks — agents can run test suites, compile code, or orchestrate complex multi-step pipelines without losing context

This isn’t just a sandboxed REPL. It’s a full execution environment that agents can own over time. For teams building coding agents, research agents, or any agent that needs to “do work” rather than just “answer questions,” this is a significant unlock.

Think SDK: Long-Running, Multi-Step Agent Framework

Alongside Sandboxes, Cloudflare is shipping Think — a new Agents SDK framework designed specifically for the long-running agent use case.

Think is positioned as the orchestration layer for agents that need to:

  • Chain multiple tool calls across time
  • Maintain context across sessions without prompt-stuffing
  • Handle failures and retries gracefully in production
  • Coordinate multi-step workflows that might run for minutes or hours

The framing here is that most existing agent frameworks were designed for short, synchronous interactions. Think is built for the async, persistent, failure-tolerant patterns that production agents actually need.

Dynamic Workers and Git-Compatible Artifacts

Two more pieces round out the Agents Week launch:

Dynamic Workers allow AI-generated code to run inside secure isolates — essentially giving agents the ability to write and execute code on the fly without spinning up full sandboxes. The isolate model borrows from Cloudflare’s existing Workers architecture, known for its fast cold-start and strong isolation properties.

Git-compatible Artifacts bring version control to agent outputs. Agents can produce structured, versioned artifacts rather than ephemeral outputs, making it easier to track what an agent did, roll back changes, and audit agent behavior over time.

Why This Matters for Practitioners

The infrastructure problem for production agents has been real: existing cloud primitives (Lambda functions, containers, even VMs) weren’t designed with agent lifecycles in mind. They’re too ephemeral, too stateless, or too heavyweight.

Cloudflare’s bet is that the right abstraction is a persistent, sandboxed execution environment with a purpose-built SDK — one that handles the messy parts of long-running agent workflows so developers don’t have to.

The fact that Sandboxes are now generally available (not beta) means this is production-ready infrastructure, not a preview. If you’re building agents that need to actually do things in the real world — run code, manage files, persist state — Cloudflare’s Agent Cloud deserves serious evaluation.

Agents Week is just beginning. More announcements are expected throughout the week.
