  1. Import repo or choose template

    You can now create a Worker by:

    • Importing a Git repository: Choose an existing Git repo on your GitHub/GitLab account and set up Workers Builds to deploy your Worker.
    • Deploying a template with Git: Choose from a brand new selection of production ready examples to help you get started with popular frameworks like Astro, Remix and Next or build stateful applications with Cloudflare resources like D1 databases, Workers AI or Durable Objects! When you're ready to deploy, Cloudflare will set up your project by cloning the template to your GitHub/GitLab account, provisioning any required resources and deploying your Worker.

    With every push to your chosen branch, Cloudflare will automatically build and deploy your Worker.

    To get started, go to the Workers dashboard.

    These new features are available today in the Cloudflare dashboard to a subset of Cloudflare customers, and will be coming to all customers in the next few weeks. Don't see it in your dashboard, but want early access? Add your Cloudflare Account ID to this form.

  1. AI Gateway adds additional ways to handle requests - Request Timeouts and Request Retries, making it easier to keep your applications responsive and reliable.

    Timeouts and retries can be used on both the Universal Endpoint or directly to a supported provider.

    Request timeouts A request timeout allows you to trigger fallbacks or a retry if a provider takes too long to respond.

    To set a request timeout directly to a provider, add a cf-aig-request-timeout header.

    Provider-specific endpoint example
    curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/workers-ai/@cf/meta/llama-3.1-8b-instruct \
    --header 'Authorization: Bearer {cf_api_token}' \
    --header 'Content-Type: application/json' \
    --header 'cf-aig-request-timeout: 5000'
    --data '{"prompt": "What is Cloudflare?"}'

    Request retries A request retry automatically retries failed requests, so you can recover from temporary issues without intervening.

    To set up request retries directly to a provider, add the following headers:

    • cf-aig-max-attempts (number)
    • cf-aig-retry-delay (number)
    • cf-aig-backoff ("constant" | "linear" | "exponential)

  1. AI Gateway has added three new providers: Cartesia, Cerebras, and ElevenLabs, giving you more even more options for providers you can use through AI Gateway. Here's a brief overview of each:

    • Cartesia provides text-to-speech models that produce natural-sounding speech with low latency.
    • Cerebras delivers low-latency AI inference to Meta's Llama 3.1 8B and Llama 3.3 70B models.
    • ElevenLabs offers text-to-speech models with human-like voices in 32 languages.
    Example of Cerebras log in AI Gateway

    To get started with AI Gateway, just update the base URL. Here's how you can send a request to Cerebras using cURL:

    Example fetch request
    curl -X POST https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY/cerebras/chat/completions \
    --header 'content-type: application/json' \
    --header 'Authorization: Bearer CEREBRAS_TOKEN' \
    --data '{
    "model": "llama-3.3-70b",
    "messages": [
    {
    "role": "user",
    "content": "What is Cloudflare?"
    }
    ]
    }'

  1. Radar has expanded its AI insights with new API endpoints for Internet services rankings, robots.txt analysis, and AI inference data.

    Internet services ranking

    Radar now provides rankings for Internet services, including Generative AI platforms, based on anonymized 1.1.1.1 resolver data. Previously limited to the annual Year in Review, these insights are now available daily via the API, through the following endpoints:

    Robots.txt

    Radar now analyzes robots.txt files from the top 10,000 domains, identifying AI bot access rules. AI-focused user agents from ai.robots.txt are categorized as:

    • Fully allowed/disallowed if directives apply to all paths (*).
    • Partially allowed/disallowed if restrictions apply to specific paths.

    These insights are now available weekly via the API, through the following endpoints:

    Workers AI

    Radar now provides insights into public AI inference models from Workers AI, tracking usage trends across models and tasks. These insights are now available via the API, through the following endpoints:

    Learn more about the new Radar AI insights in our blog post.

  1. We've revamped the Workers Metrics dashboard.

    Workers Metrics dashboard

    Now you can easily compare metrics across Worker versions, understand the current state of a gradual deployment, and review key Workers metrics in a single view. This new interface enables you to:

    • Drag-and-select using a graphical timepicker for precise metric selection.
    Workers Metrics graphical timepicker
    • Use histograms to visualize cumulative metrics, allowing you to bucket and compare rates over time.
    • Focus on Worker versions by directly interacting with the version numbers in the legend.
    Workers Metrics legend selector
    • Monitor and compare active gradual deployments.
    • Track error rates across versions with grouping both by version and by invocation status.
    • Measure how Smart Placement improves request duration.

  1. Screenshot of Terraform defining a Zone

    Cloudflare's v5 Terraform Provider is now generally available. With this release, Terraform resources are now automatically generated based on OpenAPI Schemas. This change brings alignment across our SDKs, API documentation, and now Terraform Provider. The new provider boosts coverage by increasing support for API properties to 100%, adding 25% more resources, and more than 200 additional data sources. Going forward, this will also reduce the barriers to bringing more resources into Terraform across the broader Cloudflare API. This is a small, but important step to making more of our platform manageable through GitOps, making it easier for you to manage Cloudflare just like you do your other infrastructure.

    The Cloudflare Terraform Provider v5 is a ground-up rewrite of the provider and introduces breaking changes for some resource types. Please refer to the upgrade guide for best practices, or the blog post on automatically generating Cloudflare's Terraform Provider for more information about the approach.

  1. Workers for Platforms customers can now attach static assets (HTML, CSS, JavaScript, images) directly to User Workers, removing the need to host separate infrastructure to serve the assets.

    This allows your platform to serve entire front-end applications from Cloudflare's global edge, utilizing caching for fast load times, while supporting dynamic logic within the same Worker. Cloudflare automatically scales its infrastructure to handle high traffic volumes, enabling you to focus on building features without managing servers.

    What you can build

    Static Sites: Host and serve HTML, CSS, JavaScript, and media files directly from Cloudflare's network, ensuring fast loading times worldwide. This is ideal for blogs, landing pages, and documentation sites because static assets can be efficiently cached and delivered closer to the user, reducing latency and enhancing the overall user experience.

    Full-Stack Applications: Combine asset hosting with Cloudflare Workers to power dynamic, interactive applications. If you're an e-commerce platform, you can serve your customers' product pages and run inventory checks from within the same Worker.

    index.js
    export default {
    async fetch(request, env) {
    const url = new URL(request.url);
    // Check real-time inventory
    if (url.pathname === "/api/inventory/check") {
    const product = url.searchParams.get("product");
    const inventory = await env.INVENTORY_KV.get(product);
    return new Response(inventory);
    }
    // Serve static assets (HTML, CSS, images)
    return env.ASSETS.fetch(request);
    },
    };

    Get Started: Upload static assets using the Workers for Platforms API or Wrangler. For more information, visit our Workers for Platforms documentation.

  1. You can now transform HTML elements with streamed content using HTMLRewriter.

    Methods like replace, append, and prepend now accept Response and ReadableStream values as Content.

    This can be helpful in a variety of situations. For instance, you may have a Worker in front of an origin, and want to replace an element with content from a different source. Prior to this change, you would have to load all of the content from the upstream URL and convert it into a string before replacing the element. This slowed down overall response times.

    Now, you can pass the Response object directly into the replace method, and HTMLRewriter will immediately start replacing the content as it is streamed in. This makes responses faster.

    index.js
    class ElementRewriter {
    async element(element) {
    // able to replace elements while streaming content
    // the fetched body is not buffered into memory as part
    // of the replace
    let res = await fetch("https://upstream-content-provider.example");
    element.replace(res);
    }
    }
    export default {
    async fetch(request, env, ctx) {
    let response = await fetch("https://site-to-replace.com");
    return new HTMLRewriter()
    .on("[data-to-replace]", new ElementRewriter())
    .transform(response);
    },
    };

    For more information, see the HTMLRewriter documentation.

  1. We have released new Workers bindings API methods, allowing you to connect Workers applications to AI Gateway directly. These methods simplify how Workers calls AI services behind your AI Gateway configurations, removing the need to use the REST API and manually authenticate.

    To add an AI binding to your Worker, include the following in your wrangler.toml or wrangler.json file:

    Add an AI binding to your Worker.

    With the new AI Gateway binding methods, you can now:

    • Send feedback and update metadata with patchLog.
    • Retrieve detailed log information using getLog.
    • Execute universal requests to any AI Gateway provider with run.

    For example, to send feedback and update metadata using patchLog:

    Send feedback and update metadata using patchLog:

  1. Browser Rendering now supports 10 concurrent browser instances per account and 10 new instances per minute, up from the previous limits of 2.

    This allows you to launch more browser tasks from Cloudflare Workers.

    To manage concurrent browser sessions, you can use Queues or Workflows:

    index.js
    export default {
    async queue(batch, env) {
    for (const message of batch.messages) {
    const browser = await puppeteer.launch(env.BROWSER);
    const page = await browser.newPage();
    try {
    await page.goto(message.url, {
    waitUntil: message.waitUntil,
    });
    // Process page...
    } finally {
    await browser.close();
    }
    }
    },
    };
