Now You Can See Inside Your Agents! Introducing Cloudflare Agents!

Hi everyone, Shii-chan here! Today's news lets you finally see what's really going on inside a running agent, and I can't stop being excited about it!

Cloudflare Blog blog.cloudflare.com

What was announced?

This comes from the Cloudflare Blog. Cloudflare Agents brings all of your deployed agent sessions into a single experience, surfacing key information about how your agents perform. Every model call, tool run, and token is measured, and the platform tracks agent invocations, model calls, tool executions, approval events, and sub-agent calls.

Why it matters

Cloudflare has spent nine years building out its developer platform, and agents are ultimately just another kind of application. Model access, a durable runtime, orchestration, sandboxed execution, and persistent storage were already in place. Making the inner workings of the agents running on top of that platform visible is the natural next step.

What changes

What used to be a black box is now fully visible from a dashboard.

  • Session replay: The Messages tab replays the full conversation, including system instructions, user messages, model reasoning, tool calls, and the final response
  • Trace view: A waterfall view shows exactly where time went, across parent agents, sub-agents, model calls, D1 queries, and KV operations

This telemetry lets you answer questions like: where did time go (model, tools, or infrastructure)? Did a turn stall waiting on approval? Which model was called and how many tokens did it use? Was the right tool chosen? Did an external API time out? Which sub-agent actually did the work? That's a lot more to work with when debugging or improving an agent.

Dive Deep

Supported frameworks are Think, Flue, AI SDK, and any custom harness that follows OpenTelemetry.

Setup starts with enabling Workers tracing in your wrangler.jsonc.

"observability": {
  "traces": {
    "enabled": true
  }
}

Framework-specific integration looks like this:

  • Think / Flue: emit telemetry automatically through their tracing integrations
  • AI SDK: wrap it once with the wrapAISDK() adapter
  • Custom harnesses: follow the OpenTelemetry generative AI semantic conventions

Privacy is built in too — the storeMessages and storeTools parameters let you turn off recording of payloads that might contain personal or sensitive information.

Pricing is free during the current beta. Starting October 1, 2026, it moves to:

  • Workers Free tier: 200,000 events per day (retained for 3 days)
  • Workers Paid tier: 20 million events included per month, with additional usage billed at $0.60 per million events

Cloudflare also plans to support the OpenTelemetry API directly inside Workers, which would let standards-compliant frameworks work without a Cloudflare-specific adapter.

Wrap-up

  • Cloudflare Agents brings all your deployed agent sessions into one place
  • Session replay and waterfall traces surface model calls, tool runs, approval waits, and token usage
  • Works with Think, Flue, AI SDK, and OpenTelemetry-compliant custom harnesses
  • storeMessages / storeTools let you turn off recording of sensitive payloads
  • Free during beta; from October 1, 2026, Free tier gets 200K events/day and Paid tier includes 20M events/month with usage-based pricing beyond that

If you're running agents in production on Cloudflare, or you've been frustrated by not knowing what your agent is actually doing, this one's for you!
