An open Internet depends on a model that incentivizes great content to continue to be published. Proud to partner with some of the best publishers and AI services to launch a new model built that rewards high-quality material in a new AI era.
Cloudflare is making it easier for publishers and content creators of all sizes to prevent their content from being scraped for AI training. Here's how: cfl.re/4l2cXqp

PewDiePie just made a de-google video and he is using Cloudflare Zero Trust in order to keep his self hosted services secure 🤯
no containers? well, let's fix that: $ npm create cloudflare@latest -- --template=cloudflare/templates/containers-template

Today is still the best time to join @Cloudflare
I’ve joined Cloudflare to build AI agents, and make it the best place for you to build yours! Agents are going to be everywhere, and the team here is full of incredibly talented people building internet-scale infrastructure to make that happen. Stoked to be a part of the band 🕺
You can now deep research your Cloudflare AutoRAG in workers research You can also research the web + AutoRAG for better results Just pick an existing RAG when creating a new job and that's it!
Generate pdfs, take screenshots, grab markdown + more. Just one api call away. Let me know what actions you’d like to see next~
Generating PDFs is hard. Including puppeteer in your app bundle is error-prone outside of Javascript apps. Use Cloudflare's Browser Rendering API. You can add auth, deploy it, and use it to render PDFs across projects. developers.cloudflare.com/browser-render…
Hit a very interesting issue yesterday, partly of my own making because I want everything more secure than reasonable :D Still, it turned out as a happy end because @Cloudflare is magic. 🧵
Need your AI to navigate the web? With @playwrightweb MCP + Browser Rendering, your agents can browse, click, type, upload and more. Just like a human.
We're hosting an AI Frameworks meetup if you're into AI, MCP servers, and RAGs and are around Lisbon next week. You're welcome to join. lu.ma/lvr717q6
