🔍Cloudflare Launches Agent Tracing for Workers
Your debugging just got a lot easier with agent-level spans
TL;DR
Cloudflare introduces agent tracing to its Workers platform, offering detailed insights into agent invocations and model calls. The feature is free during beta but will be priced under Observability starting October 1, 2026.
Cloudflare has launched agent tracing for its Workers platform, adding granular visibility into AI agent operations. This new layer of telemetry includes detailed spans for each invocation, model call, and tool execution, complete with metadata on token usage. Developers will benefit from enhanced debugging capabilities, especially in complex workflows involving multiple agents and tools. The feature is free during the beta period but transitions to Workers Observability pricing on October 1, 2026, with a daily limit of 200,000 events for Free tier users.

Key Points
Agent-level spans provide visibility into invocations and model calls with metadata on token usage.
Each turn produces one trace: invoke_agent {agent class} ├── chat {model} └── execute_tool {tool}
Session replay reassembles recorded conversations across turns, including messages and tool results.
Think stores message and tool payloads only if storeMessages and storeTools are set on the agent class.
Cloudflare is working to add direct support for OpenTelemetry API in future updates.
Why It Matters
If you're running complex AI workflows with multiple agents and tools, Cloudflare's new agent tracing can provide deep insights into performance and usage. However, be aware that payload recording defaults are inconsistent across different agent classes like Think and Flue.
