Logs and aggregate metrics can only get you so far. Thankfully there is a better way: CPU or memory profiling can show you the exact function where your application is using CPU or allocating memory. Today we are happy to announce support for CPU and memory profiling of Workers and Durable Objects. From the Workers Observability page, you can now request an on-demand CPU or memory profile of an active Worker, inspect it as an interactive flamegraph, and download the profile file for further analysis. This method of profiling gives you a useful perspective into what your code is doing and how you can improve it in a real-world setting. That’s because the best way to understand your application is to profile it in production. To try this on one of your Workers, you have a choice of using the CLI or the Cloudflare Dashboard. To use the CLI, make sure you have the cf package installed , then simply run: cf workers versions profile..."},"evidence_pages":[],"related_signals":[{"id":"25011c24-fc2e-4ccb-b4ee-7d0fc7172ef1","url":"https://onlylabs.fyi/signals/25011c24-fc2e-4ccb-b4ee-7d0fc7172ef1","source_url":"https://blog.cloudflare.com/transformers-on-logpush/","title":"Filter, reshape, and redact logs before export with Transformers","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-12T14:44:59+00:00","first_seen_at":"2026-10-12T16:00:52.634067+00:00","date_source":"rss.item_date"},{"id":"064b73e5-05b5-4496-a3c7-20349ac40d2f","url":"https://onlylabs.fyi/signals/064b73e5-05b5-4496-a3c7-20349ac40d2f","source_url":"https://blog.cloudflare.com/root-ksk-2024-rollover/","title":"The keys to the Internet change on October 11.
