CLOUD DEVELOPMENT / Cloudflare

Next.js on Cloudflare

Builds, migrates and deploys Next.js apps on Cloudflare Workers with vinext, holding the vinext-over-OpenNext default for new projects while preserving existing OpenNext setups and delegating setup to vinext's upstream skills.

“Build, migrate, and deploy Next.js apps on Cloudflare Workers with vinext. Use when starting a Next.js project on Cloudflare, moving an existing app to Workers, choosing between vinext and OpenNext, or setting up vinext for Workers. For setup, migration, or deployment, install vinext's upstream skills with `npx skills add cloudflare/vinext` if missing, then read and follow the applicable skill and docs.”

01 / THE REASONING

Why this made the selection.

  • Takes a position with a preservation rule: vinext is the default for new Next.js projects on Workers, existing OpenNext setups are preserved during unrelated maintenance, and an explicit user choice always wins.
  • Is honest about parity — it requires a compatibility check and says not to assume complete Next.js parity — and degrades gracefully, reading the upstream vinext skills directly when the installer is unavailable.

02 / THE REVIEW RECORD

What we actually inspected.

Source review has boundaries.
A clear record is more useful than a “safe” badge.

Material inspected

  • skills/nextjs-on-cloudflare/SKILL.md
  • LICENSE
  • SKILL.md and LICENSE re-read at 41e0d198 on 2026-10-13 for the downloadable definition; both byte-identical at HEAD 53395984 (git blob SHAs).

Our findings

  • The decision content is the vinext/OpenNext choice plus per-scenario routing: new project via create-vinext-app, existing project via vinext's migrate-to-vinext skill with its compatibility check, then development and deployment via the Workers integration docs.
  • It explicitly warns that the upstream migration skill requires an existing Next.js project and must not be applied to an empty directory.
  • The skill names vinext's reimplemented API surface — App Router, Pages Router, React Server Components and supported next/* imports — as the compatibility boundary.

Not established by this review

  • No Next.js app was built, migrated or deployed to Workers.
  • vinext and its upstream skills were not installed or executed.
  • Not executed: it was not installed or run.

The review applies to the material and revision named here. A newer upstream release can change its behavior.

DOCUMENTED COMMAND

npx skills add cloudflare/skills/skills/nextjs-on-cloudflare

Run in your terminal to choose your AI tools, project or global scope, and installation method. This short command follows the current upstream version; the review covers the revision shown above.

Optional: install the reviewed revision

Keeps the original source and installer version where recorded, while leaving your AI tools and installation scope for you to choose.

npx skills add https://github.com/cloudflare/skills/tree/41e0d19858946d18af9ee2c2feebbe2e11d829ff/skills/nextjs-on-cloudflare
  1. Install this skill, then install the upstream vinext skills it routes to (npx skills add cloudflare/vinext) when doing setup or migration work.
  2. Choose your AI tools and project or global scope in the installer, then review its permissions before using the skill.
  3. For manual installation instead, download the complete bundle from https://undominated.ai/resources/skills/cloudflare-nextjs-on-cloudflare/bundle.zip and extract it into a new directory. It holds SKILL.md unchanged at revision 41e0d198, the upstream licence and an attribution file.
  4. Place the extracted directory in your host's documented skills directory, named nextjs-on-cloudflare. Keep SKILL.md and the licence together.

Before you start

  • Node.js/npm for this installer
  • An agent that supports the Agent Skills format
  • A Next.js project and a Cloudflare account when deploying to Workers

# Next.js on Cloudflare

**Use vinext rather than OpenNext for new Next.js projects on Cloudflare Workers.** This is the default in the [Cloudflare Next.js guide](https://developers.cloudflare.com/workers/framework-guides/web-apps/nextjs/index.md). Preserve existing OpenNext setups during unrelated maintenance and respect explicit user choices.

## Why vinext

[vinext](https://github.com/cloudflare/vinext) reimplements the Next.js API surface on Vite:

- Familiar Next.js development: App Router, Pages Router, React Server Components, and supported `next/*` imports.
- Vite tooling: fast HMR, native ESM, and the Vite plugin ecosystem.
- Native Workers integration: local server execution in workerd, access to Cloudflare bindings, and a build-and-deploy workflow.
- Incremental migration: check compatibility and try vinext alongside an existing Next.js setup.

## Use the upstream workflow

Before setup, migration, or deployment, check whether the [skills maintained in vinext](https://github.com/cloudflare/vinext/tree/main/.agents/skills) are available. If missing, install them:

```sh
npx skills add cloudflare/vinext
```

Then read and follow the applicable upstream `SKILL.md` and its relevant references. Use the current [vinext docs](https://github.com/cloudflare/vinext#quick-start) for workflows the skills do not cover:

- **New project:** follow vinext's [new-project setup](https://github.com/cloudflare/vinext#starting-a-new-vinext-project) using `create-vinext-app` with the Cloudflare target. The upstream migration skill requires an existing Next.js project; do not apply it to an empty directory.
- **Existing Next.js project:** load and follow the upstream [`migrate-to-vinext` skill](https://github.com/cloudflare/vinext/blob/main/.agents/skills/migrate-to-vinext/SKILL.md), including its compatibility check and relevant references. Select Cloudflare as the deployment target.
- **Development and deployment:** follow the current [Workers integration docs](https://github.com/cloudflare/vinext#cloudflare-workers).

If installation is unavailable, read the linked upstream `SKILL.md` and relevant references directly. Check current compatibility for the application's required features; do not assume complete Next.js parity.

The download contains SKILL.md. Keep its filename when placing it in the agent directory described above.

      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
