Partial Prerendering: cached shell, streamed content.
A cached shell arrives first from Cloudflare’s CDN. Dynamic content follows as it becomes ready, in the same HTTP response.
Built for Cache Components in the App Router.

No lock-in. Plain Next.js in, plain Next.js out.
Arkor builds standard Next.js through the official Adapter API. No Arkor package, no config file. @vercel/analytics, Speed Insights and vercel.json cron keep working. Try it on your own arkor.app URL while your domain stays where it is.

What is Arkor?
Arkor is managed Next.js hosting that serves each page’s cached shell from Cloudflare’s CDN and streams the dynamic parts. Built for Partial Prerendering and Cache Components, it supports Next.js 16.3+ and is in public alpha. Deploy from GitHub; each project gets its own arkor.app address.
Which Next.js versions does Arkor support?
Next.js 16.3+ is officially supported; 16.2 generally works but is not guaranteed. Builds use Turbopack. Webpack builds are not supported, except for static exports.
Does Partial Prerendering work on Arkor?
Yes. Arkor is built around Partial Prerendering with Cache Components in the App Router: the cached shell is served from Cloudflare’s CDN and the dynamic parts stream in the same response.
Do I need to change my code to try Arkor?
No Arkor dependency or configuration file is needed. Arkor builds the Next.js app you have. @vercel/analytics, @vercel/speed-insights and vercel.json cron jobs work without changes. Apps that use Arkor storage add @stayingupwind/sdk.
Can I try Arkor without moving off Vercel?
Yes. Test your app at its own arkor.app address while your current host continues serving production. Use a custom domain you own for production on Arkor, and move it only when you are ready.
How much does Arkor cost?
Your personal team is free, with no credit card: as a launch offer, $10 of usage is included every month (the standard amount is $5), and any change will be announced in advance. Once a month’s usage reaches it, its projects pause until the next month; nothing is charged. Any other team uses Pro, $20 a month per team with $20 of usage included. There are no per-seat fees. Usage beyond that is billed at the published rates. Data transfer, function invocations and image caching are free with no usage quotas. Cache Inspector is included in Pro. Enable recording per project; recorded writes use the Inspectable ISR Write rate.
Can I use Cloudflare KV, D1, R2 and Durable Objects?
Yes. A project can create KV namespaces, D1 databases and R2 buckets and use them with @stayingupwind/sdk. Register your SQLite Durable Object classes on the Bindings page; each environment gets its own namespaces. Storage and Durable Object usage are billed at Cloudflare’s rates. Existing resources cannot be migrated in, and bringing your own Cloudflare account is not supported.
How quickly do cache updates reach visitors?
Invalidations normally propagate within a few seconds, but a location can briefly serve its previous copy while checking. Time-based regeneration can take a minute or more to reach other regions; a data center may reuse its checked copy for up to about five minutes. Render data dynamically when it must be current on every request.
Is Arkor open source?
Arkor is a managed platform. Its Next.js adapter, upwind, is open source.
Why we’re building Arkor
We’ve explored web performance in our own projects, building on the work of Vercel and the Next.js community. Arkor turns what we’ve learned into tools for other developers.
We’re starting with cached delivery and tools to inspect and debug cache behavior. As Next.js evolves, we’ll keep helping developers put its new capabilities to work in production.
