Media Updates & Release Notes

The Images binding is now billed per unique transformation, matching the model already used for URL-based transformations. Repeat requests for the same combination of source image and parameters within the same calendar month are counted only once.

Previously, every call to the binding counted as a separate transformation regardless of whether the image or parameters were unique. With this change, you can call the binding on hot paths without paying for each individual request.

Calls to .info() are no longer billed.

For more information, refer to Images pricing and the Images binding documentation.

Use the Images binding to upload, list, retrieve, update, and delete images stored in Images directly from your Worker without managing API tokens or making HTTP requests.

The env.IMAGES.hosted namespace supports the following storage and management operations:

• .upload(image, options) — Upload a new image to your account.
• .list(options) — List images with pagination.
• .image(imageId).details() — Get image metadata.
• .image(imageId).bytes() — Stream the original image bytes.
• .image(imageId).update(options) — Update metadata or access controls.
• .image(imageId).delete() — Delete an image.

For example, you can upload an image from a request body and return its metadata:

Or retrieve and serve the original bytes of a hosted image:

RealtimeKit lets you build products where people meet over live audio and video — such as HealthTech, EdTech, proctoring, and other real-time platforms — on Cloudflare's global WebRTC infrastructure.

Post-meeting transcription is now Generally Available

Post-meeting transcription is now Generally Available, so completed RealtimeKit meetings can automatically produce full transcript files after they end. Those transcripts can also power AI-generated summaries for meeting notes, review workflows, and follow-up tasks after the transcript is available.

Post-meeting transcription is a managed service powered by Workers AI using Whisper Large v3 Turbo. RealtimeKit handles transcription processing and can return transcript and summary files through webhooks or the REST API, so you do not need to run your own transcription infrastructure.

Generate transcripts and summaries by setting transcribe_on_end: true and summarize_on_end: true when creating a meeting.

Consume results via webhooks or REST API endpoints.

Supports CSV, JSON, SRT, and VTT transcript outputs, automatic language detection, Whisper language codes, and real-time transcription with Deepgram Nova-3 for live captions, in-meeting accessibility, and real-time note-taking.

Learn more in the RealtimeKit transcription docs and summary docs.

Cloudflare Realtime SFU is a WebRTC Selective Forwarding Unit that runs on Cloudflare's global network, so you can route live audio, video, and data between WebRTC clients around the world without managing SFU infrastructure or regions.

When you use the WebSocket adapter to stream WebRTC media to a WebSocket endpoint, the adapter now auto-reconnects and buffers audio and video after brief endpoint disconnects or restarts.

Many teams also use Realtime SFU as the media layer for backend applications, such as transcription, recording, note-taking, and agentic media-processing services. These systems often need to consume live WebRTC audio or video from the SFU in backend infrastructure, including Durable Objects, Workers, Containers, or external services, without running a WebRTC client themselves.

The WebSocket adapter bridges that gap by streaming WebRTC media from the SFU to a standard WebSocket endpoint as application-consumable payloads: PCM audio frames and JPEG video frames.

Reconnect behavior:

• Audio uses a short bounded backlog to reduce audible loss. If the interruption lasts longer than the backlog can cover, older audio may be dropped.
• Video resumes from the latest available JPEG frame instead of replaying stale frames.
• Recovery is best effort and does not guarantee gapless or exactly-once delivery.

If the endpoint remains unavailable after the 5-second reconnect window, the adapter closes and must be recreated.

You can now record specific participant audio tracks in RealtimeKit with track recording. Track recording creates separate WebM files for each participant instead of a single composite recording, which is useful for post-processing, transcription, and regulated or content-sensitive workflows.

To record specific participants, pass user_ids when starting a track recording.

Minimum SDK versions required for selective track recording:

• Web Core: @cloudflare/realtimekit version 1.4.0 or later
• Web UI Kit: @cloudflare/realtimekit-ui, @cloudflare/realtimekit-react-ui, or @cloudflare/realtimekit-angular-ui version 1.1.2 or later
• Android Core or iOS Core: version 2.0.0 or later
• Android UI Kit or iOS UI Kit: version 1.1.0 or later

RealtimeKit provides SDKs and UI components so that you can build your own meeting experience on Cloudflare's global WebRTC infrastructure. Teams today build products ranging from telehealth to education on RealtimeKit for global audiences. You can get started today with our Quickstart or take a look at our Cloudflare Meet repo as a reference.

Flows are automated rules that pair conditions (such as file extension, URL path, or query parameter) with parameters. Set up a flow to automatically apply image optimization to matching requests on your zone without writing code or changing URLs.

There are two modes for transformation flows:

• Provider flows — Migrate from another image optimization service. Your existing URLs continue to work while Cloudflare rewrites provider-specific parameters to their Cloudflare equivalents. Currently, Cloudflare supports provider flows for Fastly Image Optimizer.
• Custom flows — Define your own conditions and actions for use cases like automatic format conversion, responsive sizing with width=auto, or directory-based optimization.

To get started, go to Images > Transformations > Automation in the Cloudflare dashboard.

Learn more about transformation flows.

You can now interact with your Stream video library using new bindings for Workers!

This allows customers to upload content to Stream, provision direct uploads, manage videos, and generate signed URLs from a Worker without making authenticated API calls. We're excited to bring Stream and Workers closer together to empower more programmatic pipelines, tighter integrations, and support generative AI and inference workloads.

Use the Stream binding when you want to:

• Upload videos from URLs or create basic direct upload links for end users
• Generate signed playback tokens without managing signing keys
• Manage video metadata, captions, downloads, and watermarks
• Build video pipelines entirely within Workers

To get started, add the Stream binding to your Wrangler configuration.

Generate a video with AI and upload directly to Stream or send a URL of a file you already have.

Generate a signed URL without using a signing key or an API call.

Get and set video properties easily.

For setup instructions and the full API reference, refer to Bind to Workers API.

Get started with your Agent by adding a binding for Cloudflare Stream (env.STREAM). On the watch page, use the Stream binding to get info based on the ID, and leverage video.meta.name as the page title.

You can now use a Workers binding to transform videos with Media Transformations. This allows you to resize, crop, extract frames, and extract audio from videos stored anywhere, even in private locations like R2 buckets.

The Media Transformations binding is useful when you want to:

• Transform videos stored in private or protected sources
• Optimize videos and store the output directly back to R2 for re-use
• Extract still frames for classification or description with Workers AI
• Extract audio tracks for transcription using Workers AI

To get started, add the Media binding to your Wrangler configuration.

Then use the binding in your Worker to transform videos.

Output modes include video for optimized MP4 clips, frame for still images, spritesheet for multiple frames, and audio for M4A extraction.

For more information, refer to the Media Transformations binding documentation.

Real-time transcription in RealtimeKit now supports 10 languages with regional variants, powered by Deepgram Nova-3 running on Workers AI.

During a meeting, participant audio is routed through AI Gateway to Nova-3 on Workers AI — so transcription runs on Cloudflare's network end-to-end, reducing latency compared to routing through external speech-to-text services.

Set the language when creating a meeting via ai_config.transcription.language:

{
  "ai_config": {
    "transcription": {
      "language": "fr"
    }
  }
}

Supported languages include English, Spanish, French, German, Hindi, Russian, Portuguese, Japanese, Italian, and Dutch — with regional variants like en-AU, en-GB, en-IN, en-NZ, es-419, fr-CA, de-CH, pt-BR, and pt-PT. Use multi for automatic multilingual detection.

If you are building voice agents or real-time translation workflows, your agent can now transcribe in the caller's language natively — no extra services or routing logic needed.

See Transcription docs, Nova-3 model page, Workers AI, AI Gateway.

Cloudflare Workflows: Access current retry attempt

Cloudflare Workflows allows you to configure specific retry logic for each step in your workflow execution. Now, you can access which retry attempt is currently executing for calls to step.do() :

await
step.do(
"my-step",
async (ctx) =>
=>
{
// ctx.attempt is 1 on first try, 2 on first retry, etc.

console.log(`Attempt${${ctx.attempt}}`);
}
);

You can use the step context for improved logging & observability, progressive backoff, or conditional logic in your workflow definition.

Note that the current attempt number is 1-indexed. For more information on retry behavior, refer to
Sleeping and Retrying.

Radar ships several new features that improve the flexibility and usability of the platform, as well as visibility into what is happening on the Internet.

Region filtering

All location-aware pages now support filtering by region, including continents, geographic subregions (Middle East ↗, Eastern Asia ↗, etc.), political regions (EU ↗, African Union ↗), and US Census regions/divisions (for example, New England ↗, US Northeast ↗).

Traffic volume by top autonomous systems and locations

A new traffic volume view shows the top autonomous systems and countries/territories for a given location. This is useful for quickly determining which network providers in a location may be experiencing connectivity issues, or how traffic is distributed across a region.

The new AS and location dimensions have also been added to the Data Explorer ↗ for the HTTP, DNS, and NetFlows datasets. Combined with other available filters, this provides a powerful tool for generating unique insights.

Finally, breadcrumb navigation is now available on most pages, allowing easier navigation between parent and related pages.

Check out these features on Cloudflare Radar ↗.

REST API rate limits

REST API rate limits for Workers Paid plans have been increased from 3 requests per second (180/min) to 10 requests per second (600/min). No action is needed to benefit from the higher limit.

The REST API lets you perform common browser tasks with a single API call, and you can now do it at a higher rate.

• /content - Fetch HTML
• /screenshot - Capture screenshot
• /pdf - Render PDF
• /markdown - Extract Markdown from a webpage
• /snapshot - Take a webpage snapshot
• /scrape - Scrape HTML elements
• /json - Capture structured data using AI
• /links - Retrieve links from a webpage

If you use the Workers Bindings method, increases to concurrent browser and new browser limits are coming soon. Stay tuned.

For full details, refer to the Browser Rendering limits page.

The Gateway Authorization Proxy and PAC file hosting are now in open beta for all plan types.
Previously, proxy endpoints relied on static source IP addresses to authorize traffic, providing no user-level identity in logs or policies. The new authorization proxy replaces IP-based authorization with Cloudflare Access authentication, verifying who a user is before applying Gateway filtering without installing the WARP client.
This is ideal for environments where you cannot deploy a device client, such as virtual desktops (VDI), mergers and acquisitions, or compliance-restricted endpoints.

Key capabilities

• Identity-aware proxy traffic — Users authenticate through your identity provider (Okta, Microsoft Entra ID, Google Workspace, and others) via Cloudflare Access. Logs now show exactly which user accessed which site, and you can write identity-based policies like "only the Finance team can access this accounting tool."
• Multiple identity providers — Display one or multiple login methods simultaneously, giving flexibility for organizations managing users across different identity systems.
• Cloudflare-hosted PAC files — Create and host PAC files directly in Cloudflare One with pre-configured templates for Okta and Azure, hosted at https://pac.cloudflare-gateway.com// on Cloudflare's global network.
• Simplified billing — Each user occupies a seat, exactly like they do with the Cloudflare One Client. No new metrics to track.

Get started

• In Cloudflare One ↗, go to Networks > Resolvers & Proxies > Proxy endpoints.
• Create an authorization proxy endpoint and configure Access policies.
• Create a hosted PAC file or write your own.
• Configure browsers to use the PAC file URL.
• Install the Cloudflare certificate for HTTPS inspection.

For more details, refer to the proxy endpoints documentation and the announcement blog post announcement blog post.
