Cloudflare Tail Workers
Use Tail Workers when execution events need custom processing. Fetch the current documentation before implementing handlers, configuration, or integrations.
| Task | Documentation |
|---|---|
| Decide whether custom processing is needed | Tail Workers |
| Export logs and traces to an observability destination | Exporting OpenTelemetry Data |
| Inspect a deployment interactively | Real-time logs |
| Implement the consumer | Tail handler |
Before adding a Tail Worker, check whether built-in OpenTelemetry export meets the destination’s needs. Use the Tail Workers guide for the tradeoff, then identify the custom filtering or transformation that remains necessary.
