Cloudflare Gateway can now hand traffic to a customer's Worker on every Zero Trust plan

Cloudflare added a Forward action and custom validation functions to Gateway, putting customer Workers inside policy evaluation on all Zero Trust plans. Cloudflare says the hand-off is a local function call on the same machine. Operators still need to know what happens to a blocking decision when their code fails.

Cloudflare takes Hyperdrive's MySQL pooler to GA after 20 bug fixes

Workers Issues can now wake an incident agent through a signed MCP Event

Cloudflare's API MCP server sends a signed MCP Event to a client webhook when Workers Issues detects a new or recurring production failure. An incident agent can start from that event without a polling loop. A dev.to walkthrough says the event should open a read-only investigation and leave any production change behind human approval.

Cloudflare Traces exposes its proxy as OpenTelemetry spans billed by the gigabyte

Cloudflare put Traces into open beta, turning security rules, cache, routing and origin handling into OpenTelemetry spans with no code to write. From December 1 those spans, and Workers Tracing, are billed per gigabyte, so sampling rates now set the bill.

carrier-explode turns iPhone, Pixel and Galaxy firmware into a searchable index of carrier settings

Alec Dusheck's carrier-explode decodes carrier settings from iPhone, Pixel and Galaxy firmware into a searchable site, an API and an 8.39 MiB daily dataset. Its decoders are still in development, so each result is a lead to verify on a real phone and network.

Cloudflare adds on-demand production profiling for Workers and Durable Objects

Cloudflare now lets Workers and Durable Objects users take on-demand CPU and memory profiles in production and view them as flamegraphs. Each capture runs for a window the user sets and can be saved from the CLI to a .pprof file for further analysis.

Cloudflare routes agent web search through AI Gateway with three crawler-vetted providers

Cloudflare now sells web search from Ceramic.ai, Exa and Linkup through AI Gateway at partner list prices, billed from gateway credits with no markup. Teams already on the gateway skip a separate search vendor account, though their agents still have to issue each search call.

Cloudflare's Artifacts beta wires Git repository events straight into Workers for AI agents

Cloudflare put Artifacts, a Git platform for AI agents, into open beta with three primitives: repo event subscriptions, Workers bindings and region controls. The detail comes from a third-party dev.to write-up, and its latency and residency claims still need confirming in Cloudflare's documentation.

Cloudflare's Issues for Workers needs a triage step before errors reach a coding agent

Cloudflare's Issues for Workers, in open beta since September 30, can send grouped production errors and the affected Worker version to a coding agent. A dev.to walkthrough argues each failure needs sorting first, since a correct refusal can arrive looking like a bug.

Cloudflare Traces records edge rule, cache and routing decisions as OpenTelemetry spans

Cloudflare has put Traces into open beta, recording each supported step a request takes through its edge as an OpenTelemetry span. The spans export to any OTLP endpoint, so edge decisions can sit in the tracing backend a team already runs.

Ahrefs and three rival bot-analytics tools run a Cloudflare Worker on every file a page loads

Ahrefs, Known Agents, Profound and Scrunch run a Worker on every request, so a 20-file page spends 21 of Cloudflare's 100,000 free daily invocations. A site with 10,000 page views a day would need more than twice that.
