Deno is joining Cloudflare
The Deno team is joining Cloudflare to radically simplify self-hosting Workers and Durable Objects so developers can use the same primitives in more places. For what this means and how it came about, here’s the story from Ryan Dahl, Senior Principal Engineer, and Kenton Varda, Distinguished Engineer.
Bridging technical depth and usability: The story behind Radar’s redesign
We redesigned Cloudflare Radar to make real-time global traffic and outage data accessible to a wider audience — including journalists, less technical researchers, and everyday users. By introducing an interactive map and standardized components, we simplified navigation while preserving technical depth.
Building an evidence-grounded agentic security operations harness on Cloudflare
Cloudflare Managed Defense uses a team of specialized AI agents built on Workers and global network telemetry to analyze security alerts. By separating deterministic evidence collection from model inference, the system delivers grounded recommendations to Managed Defense Analysts.
The keys to the Internet change on October 11. Are you ready?
On October 11, 2026, the DNS root switches to a new key-signing key (KSK-2024). Learn what this means for you, and how RFC 8509 trust anchor sentinels allow you to test whether your DNS resolver is ready for the rollover.
One year later: the power of 1.1.1.1 interns
A year after announcing our goal to hire 1,111 interns, more than 750 early-career builders have shipped real products across 48 teams at Cloudflare. From Birthday Week launches to post-quantum security, our interns prove that AI amplifies human potential instead of replacing it.
Everything we launched during Birthday Week 2026
We celebrated our 16th birthday with 46 announcements across open source, post-quantum security, AI agents, and developer platform upgrades. Here’s a day-by-day roundup of everything we shipped.
Streamline: custom video pipelines with Cloudflare Stream and Workers
Streamline demonstrates how to build long-running, continuous video processing pipelines by pairing Cloudflare Workers and Durable Objects with a containerized media engine.
Introducing Web Search API via AI Gateway
Cloudflare AI Gateway now supports native web search API integration in partnership with Ceramic.ai, Exa, and Linkup. Developers can now inject real-time web context into model inference calls via AI Gateway, REST APIs, or Workers bindings.
Protected Quick Tunnels: simple accountless authentication for your next dev project
Quick Tunnels now support email authentication. Add --allowed-mail to one cloudflared command, and only the addresses or domains you list can reach your local app. No Cloudflare account required on either side.
Introducing Cloudflare Traces: follow requests through our entire platform
Cloudflare Traces shows how a request moves through security rules, transformations, cache, routing, Workers, and your origin, then follows it across services running anywhere in your stack.
Building for good: How civil society organizations are automating on Cloudflare
Some of the world's leading organizations are building the future of non-profit work with Cloudflare.
Updates on our pledge to make Cloudflare features accessible to everyone
A year after pledging to eliminate two-tier product access, Cloudflare has expanded Logpush, multi-account governance, and higher platform limits to all accounts. Here is an update on our progress, how we dogfood these tools internally, and what is coming next.
8 major updates to Cloudflare Observability
Cloudflare is launching eight major updates that bring logs, traces, analytics, alerts, dashboards, querying, and telemetry export into one observability platform, with simpler and more predictable pricing.
Announcing Cloudflare OHTTP Gateway – expanding access to Cloudflare’s privacy-preserving infrastructure
We’re announcing the closed beta of a self-serve Cloudflare OHTTP Gateway. We’re also renaming our Privacy Gateway to Cloudflare OHTTP Relay to better distinguish the two products.
2026 Birthday week: network performance update
Cloudflare now ranks as the fastest provider across 74% of the top 1,000 global networks. By incorporating background telemetry from Cloudflare Challenge Pages, we have expanded our real-user measurement scale while maintaining user privacy.
Follow the thread: a new dashboard to investigate account abuse
Fraudsters are increasingly using AI to bypass stateless security checks. Cloudflare's new Account Abuse Protection dashboard uses stateful analysis and edge-generated Hashed User IDs to help teams investigate and block account abuse.
Introducing Clef: our open-source decision models, and new RL fine-tuning platform
We are introducing Clef and Clef-flash, open-source decision models hosted on Workers AI for high-speed classification and agentic workflows. Also launching: a new reinforcement learning platform that allows developers to fine-tune decision models using their own data.
One year later: Sovereign AI and the fight for choice
AI sovereignty is not a zero-sum game, but many governments now believe it is. Cloudflare's answer: more local open-source models, model-agnostic security tools, and a commitment to giving nations genuine choice.
Introducing Workers KV Instant — powered by Quicksilver
Workers KV Instant delivers sub-2ms p99 read latencies and 250ms global replication across Cloudflare’s 300+ edge locations. KV Instant eliminates cold-read penalties and uses the familiar Workers KV API.
Introducing Cloudflare Basin: an open, serverless data platform, now generally available
Cloudflare Basin is built on Apache Iceberg and R2 Object Storage. With general availability, developers can ingest, manage, and query large datasets at scale without paying data egress fees.
Cloudflare Impact reaches $100 million in donations
