Vercel Blob is now generally available, providing durable storage that's integrated with Vercel's application delivery network
Storage should be simple to set up, globally available, and built to last, without slowing you down or adding complexity. It should feel native to your app.
That's why we built Vercel Blob: AWS S3-backed storage that's deeply integrated with Vercel's global application delivery and automated caching, with predictable pricing to serve public assets cost-efficiently at scale.
Vercel Blob is now generally available. It's already storing and serving over 400 million files, and powers production apps like v0 and the Vercel Dashboard.




Built for performance, durability, and efficiency
Vercel Blob is built for high-volume workloads, whether you’re storing a few profile pictures or terabytes of media.
Vercel Blob introduces Blob Data Transfer, a new high-volume delivery strategy separate from Fast Data Transfer, that leverages alternative infrastructure to deliver assets at optimized cost. Blob Data Transfer is volume-optimized infrastructure (18 hubs) to deliver assets at optimized cost, while Fast Data Transfer remains latency-optimized (94 cities) for ultra-low latency.
Blob is powered by AWS's S3 infrastructure, ensuring 99.999999999% of reliability. To put this into context, even with one billion objects stored, you could go 100 years without losing a single one. Blob is built to be always available, resistant to failures, and instantly accessible.




Caching that just works
Vercel Blob’s deep integration with Vercel’s caching infrastructure abstracts away management and configuration, handling data transfer as part of the standard request lifecycle.
When a request for a Blob asset is made:
The request is routed to the nearest Vercel Region, like any standard Vercel Edge Request
The Region identifies it as a Blob request and queries the Vercel cache
On a cache
HIT
, it’s served directly from the cacheOn a cache
MISS
, the asset is fetched from Blob storage using Fast Origin Transfer and stored in the cache
The response is returned to the user, incurring Blob Data Transfer
By unifying storage and delivery inside Vercel’s network, Blob Data Transfer and the Vercel CDN deliver industry-leading cost-performance efficiency, no separate CDN required.




How Blob fits into your app
Vercel provides an SDK to make file uploads easy. Installing @vercel/blob
makes uploading a file to Blob a single function call. This example creates a Vercel Function that accepts a file and returns a public URL:
import { put } from '@vercel/blob';
export async function PUT(request: Request) { const form = await request.formData(); const file = form.get('file') as File; const blob = await put(file.name, file, { access: 'public', addRandomSuffix: true });
return Response.json(blob);}
Vercel Blob supports large uploads up to 5TB with built-in support for multi-part uploads, resumability, retries, and concurrency, enabled by the Vercel Blob SDK. You can track progress from the client and handle large media or user-generated content without workarounds.
Once uploaded, the file is immediately publicly available and cached across Vercel’s delivery network. Each upload can be traced back to its storage location, as every file in Blob uses a structured path format.




As with all assets, Vercel Blob integrates directly with Vercel Image Optimization, allowing you to store and optimize images within the same workflow. Instead of serving static images from traditional storage, Blob URLs can be used in framework-native image optimization, like next/image
in Next.js, enabling transformations such as resizing, format conversion, and compression automatically.
import Image from 'next/image';
export default function Profile() { return ( <Image src="https://ce0rcu23vrrdzqap.public.blob.vercel-storage.com/profiles/user-abcde-NoOVGDVcqSPc7VYCUAGnTzLTG2qEM2.png" width={200} height={200} alt="User profile" /> );}
You can also browse and manage files directly in the Vercel dashboard.
How it's priced
Storage should be fast, reliable, and built for scale with a transparent pricing model, whether you’re storing a few files or serving terabytes of media.
Vercel Blob pricing is usage-based and in line with what developers already understand, with regional pricing for Pro and Enterprise customers.
Storage and operation pricing are identical to Amazon S3. Blob Data Transfer is 3x more cost-efficient than Fast Data Transfer on average, thanks to its region-optimized architecture. Free data transfer allotments have doubled since beta.
Requests using Image Optimization, whether the images are stored in Blob or elsewhere, continue to use Fast Data Transfer because images are key to FCP/LCP and benefit from the latency-optimized network. Combined with format and size optimization, this could reduce costs compared to serving unoptimized images over Blob Data Transfer.
New: Blob Observability Tab
The Observability dashboard now includes a dedicated tab for Vercel Blob, which provides visibility into how Blob stores are used across your applications.


At the team level, you can see total data transfer, download volume, cache activity, and API operations. You can also drill into activity by user agent, Vercel region, and client IP.
This allows you to understand real-world usage patterns, identify inefficiencies, and optimize how your application stores and serves assets.
What's next for Vercel Blob
Blob is production-ready and already powering high-scale apps. We’re still iterating based on what developers need most with upcoming features that include private Blobs with scoped access for authenticated requests and data residency controls to let you choose where your data is stored. We’re also continuing to improve the local developer experience with better tooling for offline and local development.
Vercel Blob is storage built for the web: fast, globally distributed, and natively integrated into the Vercel platform. It connects directly to your frontend apps and workflows, making it ideal for user-generated content, media assets, or static files. Blob simplifies storage without sacrificing performance or cost.
