Somewhere and Vercel
A complete backend, with less for your agent to wire together.
Somewhere brings your app’s users, data, permissions, files and background work into one platform contract. That integration is the product: less application plumbing to write and maintain.
Build on SomewhereCompare responsibilities.
| Need | Somewhere | Vercel and your application |
|---|---|---|
| Application code | React and TypeScript, with platform server functions and declared data. | Framework choice, including native support for Next.js. |
| Backend services | Built-in sign-in, database, files, email, AI and jobs behind the project contract. | Vercel services and integrations you select and connect to your application. |
| Data permissions | Declared access rules enforced by the platform; privileged server actions remain your responsibility. | Your application and selected backend establish and enforce the authorization model. |
| Rendering | Automatic rendering for eligible public React routes, with browser fallback and no authored loaders. | Framework-specific rendering, caching and revalidation, including Next.js server rendering. |
| Agent workflow | CLI and MCP access to app deployment, backend configuration and diagnostics. | Vercel tools plus the interfaces of the backend services your application uses. |
Somewhere supplies these capabilities as one integrated app contract. With Vercel, you choose the combination of services and application code that fits your product.
What you can use today. What comes next.
Live means available now within the scope below. Building means implementation is underway. Planned means a direction, not a shipped capability. Reviewed October 24, 2026.
Public pages with real content
Eligible public routes can serve rendered HTML, including declared public database reads. The platform caches that output and invalidates it when its tracked data changes. Generated sitemaps can include discovered public data routes.
One app, one backend contract
Sign-in, database access rules, files, email, AI and background jobs are available through the platform. Your app still decides its business rules and which actions a person may take.
A clearer next step when something fails
We are improving agent-facing errors and connecting shape-only failure evidence to incident triage. Automatic reproduction and rollback signals are not complete.
Data ready with the first private page
Signed-in page prefetch would deliver authorized data with the page, without putting personal results in a shared cache. It is not available today.
How public rendering works.
Public rendering happens on demand; it does not hold up deployment. On a first visit, the platform waits up to 2.5 seconds for rendered output, then can serve the browser-rendered page while rendering finishes. Unsupported pages also use browser rendering.
The shared render path accepts anonymous public reads. Signed-in and private data are excluded. Dynamic sitemap discovery is bounded; it is not a promise to enumerate every possible application URL. Tracked data changes invalidate cached output; the accepted cache age ceiling is 120 seconds, not a guaranteed sub-minute refresh for every route.
You keep writing ordinary React and declared data access. There are no authored server loaders for this public rendering path. Somewhere does not execute Next.js App Router, Server Component or ISR application code.
Make the comparison on the app you need.
For a new app with users, data and workflows, Somewhere is built to reduce the work between an idea and a functioning product. For code that already depends on Next.js internals, changing platforms includes adapting that code. We do not claim identical framework behavior.
Compare speed on the same workload and required behavior. For cost, use the current pricing and allowances for your application.
