turns out you can just send a prompt to Browser Run and have it shape the output however you want.

here's the Cloudflare blog as RSS feed, it renders the page, an AI picks out the articles, and you get a real feed URL

Crawlers don't run your JavaScript, so they never see the actual content on JS-heavy pages.

New Browser Run tutorial on how to pre-render pages at the edge with a Cloudflare Worker
--> Crawlers get full HTML
--> Users get normal SPA experience

weekend hack. In the next version of agents sdk:

- codemode has a new connector runtime model, durable abort/replays, with approvals and snippets (hanks @mattzcarey)
- browser tools get a full upgrade, where you can drive a single session durably, driven by new codemode (thanks @cjols_ / @whoiskatrin)
- bonus: live view (that you can interact with!), quick actions (markdown, screenshot, pdf generation, etc)

yay for dynamic workers. that (and some more stuff) should be all out on monday.

Browser Run's /snapshot endpoint now accepts a formats parameter. So your agent gets the info it needs in one request

formats: screenshot, markdown, accessibility tree, html

Cloudflare has acquired Vite / VoidZero

Void is vite's fullstack Intertia-like framework.

This gives Cloudflare control over the entire stack. They have all the primitives from frontend/backend framework, linting, testing, formatting, JS runtime, db, kv, inference, blob storage, access, etc...

smart move. A tidy package they can hand to an LLM to make a site.

You can now call Browser Run Quick Actions directly from your Worker with env.BROWSER.quickAction()

HTML, screenshots, markdown, pdfs + more, all through a binding (no api tokens needed!)

*taps roof of container* this baby can fit so many browsers

but rly... @cloudflare browser run is on 🔥

you can now spin up 60 browsers per minute and run up to 120 concurrently — 4x the previous limit! AND quick action response times are 50% faster

@emanueledpt stop building vibe codeable products for vibe coders that are vibe coding using these products lol

i think the further your audience is from tech people who know about (vibe) coding, the more money you can make

we are just too stuck in this bubble

Browser Rendering is now Browser Run, with Live View, Human in the Loop, CDP access, session recordings, and 4x higher concurrency limits for AI agents. https://t.co/uVsYYLhsRN

[kathyl @kathyyliao]

your coding agents can now use Browser Rendering as a remote browser

CDP is how browser automation works under the hood, so now your agents get max control over the browser

@jlongster is this for work or personal or both? For work, I'm a heavy user of a /daily-briefing skill to keep me honest with ongoing commitments and inbound threads threads I should be paying attention to. Chronological makes most sense there for me there as topics tend to be ephemeral

[Arvind @TipsCsharp]

Cloudflare just dropped Dynamic Workers and it's a massive deal for AI agents.

The problem: AI agents generate code. That code needs a sandbox. Containers take 100-500ms to boot and 100-500MB RAM.

Dynamic Workers use V8 isolates instead:
- Startup: 1-5ms (100x faster)
- Memory: few MB (100x less)
- No warm pools needed
- Unlimited concurrency
- Runs on same thread as host

The killer feature: TypeScript API definitions replace OpenAPI specs. Fewer tokens, cleaner code, type-safe RPC across the sandbox boundary via Cap'n Web RPC.

Code Mode: LLM writes TS code → runs in isolate → calls typed APIs → only final result returns to context. 81% fewer tokens vs sequential tool calls.

$0.002 per Worker loaded/day. Free during beta.

This is the serverless sandbox containers should have been.

[Cloudflare Developers @CloudflareDev]

New! The Browser Rendering REST API is live.

If you're building AI Agents, you can use it for:
✅ Capturing screenshots
📄 Generating PDFs
🔍 Extracting content
🤖 Scraping web elements

It's possible to build your whole app in Cloudflare workers but it's an edge case

Managed Components are changing the way third-party tools integrate with websites. This is a great time to learn what they are and how to use them https://t.co/8mepnuhXdT

On Tuesday I gave evidence to the House of Lords’ Communications and Digital Committee inquiry into BBC future funding.

Here’s a short thread summarising the data on UK news use/attitudes behind what I said.

Basically everyone around me at Cloudflare is hiring right now, including myself. PM? Engineer? Manager? DM if even remote possibility and will do my best to connect you with the right people
