vercel-to-createos

name

vercel-to-createos

description

Migrate Next.js, Vite, React, Vue, Svelte, and other web applications from Vercel to CreateOS. Parses vercel.json, maps environment variables, detects framework and build settings, and deploys to CreateOS via the CreateOS MCP server. Use this skill whenever the user mentions migrating from Vercel, leaving Vercel, moving a deployment off Vercel, replacing Vercel, or when a repository contains a vercel.json file and the user wants to deploy elsewhere. Also use when the user references concerns about Vercel reliability, pricing, security, or the Vercel breach, and wants an alternative.

Vercel → CreateOS Migration

This skill migrates a project currently deployed on Vercel to CreateOS. It reads the existing Vercel configuration, translates it into a CreateOS project, provisions environments and environment variables, and triggers the first deployment — all through the CreateOS MCP server.

---

When to use this skill

Activate this skill when any of the following is true:

• The user explicitly asks to migrate, move, or deploy from Vercel to CreateOS.
• The user expresses intent to leave Vercel (pricing, reliability, security, ownership concerns).
• The repository contains a vercel.json, .vercel/ directory, or @vercel/* dependencies in package.json.
• The user asks for a "Vercel alternative" or references the April 2026 Vercel security incident.

Do NOT use this skill when:

• The user is deploying a fresh project with no prior Vercel deployment — use the standard createos skill instead.
• The project is a pure Next.js application with heavy dependencies on Vercel-specific features (Edge Middleware, Vercel KV, Vercel Blob, Vercel Postgres). Surface compatibility notes before proceeding.

---

Prerequisites

Before running any migration steps, confirm the user has:

1. A CreateOS account — if not, direct them to https://createos.nodeops.network to sign in via Email, GitHub, Google, or Wallet.
2. CreateOS MCP connected OR a CREATEOS_API_KEY environment variable set.
3. Access to their current Vercel project's environment variables (they may need to export these from the Vercel dashboard).
4. GitHub repository access for the project (CreateOS deploys from GitHub for VCS projects).

If the user does not have their Vercel environment variables accessible, pause the migration and provide these instructions:

Export your Vercel environment variables by running vercel env pull .env.vercel.backup in your project directory, or download them from Project Settings → Environment Variables in the Vercel dashboard. Keep this file local and do not commit it.

---

Migration workflow

Follow these steps in order. Do not skip steps. Report progress to the user after each completed step.

Step 1: Inventory the Vercel project

Read the following files from the repository if they exist:

• vercel.json — build, routing, function, and header configuration
• package.json — detect framework, build scripts, and Node.js version
• next.config.js / next.config.mjs / next.config.ts — Next.js specific configuration
• .nvmrc — Node version pin
• Any .env* files for reference (do NOT read secrets; only note which keys exist)

Produce a short summary for the user:

Detected project:
- Framework: [Next.js 14 / Vite / Remix / etc.]
- Node version: [20.x]
- Build command: [npm run build]
- Output directory: [.next]
- Environment variables needed: [count, with names — NOT values]
- Vercel-specific features in use: [list any edge middleware, KV, blob, etc.]

Step 2: Flag incompatibilities before proceeding

Check for Vercel-specific features that do not have direct CreateOS equivalents. If any are present, STOP and confirm with the user how they want to handle each before continuing.

Vercel feature	CreateOS handling
Edge Functions / Middleware	Runs as standard Node runtime on CreateOS — confirm latency impact is acceptable
Vercel KV	Migrate to CreateOS Valkey (Redis-compatible managed service)
Vercel Postgres	Migrate to CreateOS managed PostgreSQL
Vercel Blob	Use any S3-compatible storage; CreateOS does not provide blob storage natively
Image Optimization	Next.js image optimization works on CreateOS but uses the standard Node adapter
ISR / On-demand revalidation	Supported via standard Next.js caching; confirm revalidation paths work
Cron jobs	Use CreateOS cronjob support (see CreateCronjob MCP tool)
Preview deployments	Map to CreateOS preview environments (one per branch)

Step 3: Create the CreateOS project

Use the CreateOS MCP to create a new VCS-type project. Note: CreateOS uses a nested shape — source carries the GitHub linkage and settings carries build/runtime config. The deployment branch is set on the project's environment (Step 3b), not on the project itself.

1. Call ListConnectedGithubAccounts to verify GitHub is connected. The response includes the installationId you need for the next call. If no accounts are connected, call InstallGithubApp and pause for user action.

2. Call ListGithubRepositories(installationId) and confirm the target repo with the user. Capture the repo's id — that is the vcsRepoId.

3. Call CheckProjectUniqueName({uniqueName}) to validate the proposed project name. uniqueName must match ^[a-zA-Z0-9-]+$, 4–32 chars.

4. Call CreateProject with the nested source/settings shape. Two valid patterns — pick one:

   Pattern A — Build AI (recommended default). Use this when you cannot derive exact installCommand / buildCommand / runCommand from vercel.json + package.json with high confidence. CreateOS auto-detects from the repo:

   CreateProject({
     "uniqueName": "<derived from project name>",
     "displayName": "<human-friendly name>",
     "type": "vcs",
     "source": {
       "vcsName": "github",
       "vcsInstallationId": "<from step 1>",
       "vcsRepoId": "<from step 2>"
     },
     "settings": {
       "useBuildAI": true,
       "runtime": "<see runtime mapping below — required>",
       "port": 80
     }
   })
   

   Pattern B — Explicit commands. Use this when vercel.json gives you concrete commands and a known framework. All command fields, when included, must be non-empty strings — omit fields entirely rather than passing "" (empty strings cause a 400):

   CreateProject({
     "uniqueName": "<derived from project name>",
     "displayName": "<human-friendly name>",
     "type": "vcs",
     "source": {
       "vcsName": "github",
       "vcsInstallationId": "<from step 1>",
       "vcsRepoId": "<from step 2>"
     },
     "settings": {
       "framework": "<see mapping table below — omit if no slug fits>",
       "runtime": "<see runtime mapping below>",
       "port": 3000,
       "directoryPath": ".",
       "installCommand": "<from package.json or vercel.json installCommand>",
       "buildCommand": "<from vercel.json buildCommand or package.json build script>",
       "runCommand": "<framework default, e.g. 'npm start' for Next.js>",
       "buildDir": "<from vercel.json outputDirectory or framework default, e.g. '.next'>"
     }
   })
   

   Required-in-practice fields (the API rejects without them, even though some are marked optional in the schema):

   • port — always include. Use 80 for static-shaped sites, 3000 for Node app defaults, or whatever the app actually listens on.
   • runtime — always include unless framework is set (and even then, include it for safety).
   • Either useBuildAI: true OR a complete command set (installCommand + buildCommand + runCommand). Mixing partial commands with useBuildAI: false causes a 400.

3b. Call CreateProjectEnvironment(project_id, body) to create the production environment. All five body fields below are required by the API — description, settings, and resources are not optional even though the docs may suggest otherwise. The resources triplet is all-or-nothing: include cpu, memory, and replicas together or omit resources entirely.

CreateProjectEnvironment(project_id, {
  "displayName": "Production",
  "uniqueName": "production",
  "description": "Production environment migrated from Vercel",
  "branch": "main",
  "isAutoPromoteEnabled": true,
  "settings": { "runEnvs": {} },
  "resources": { "cpu": 200, "memory": 500, "replicas": 1 }
})

Without this call, the project has no environment to deploy to. Resource limits: cpu 200–500 millicores, memory 500–1024 MB, replicas 1–3.

Framework mapping (settings.framework):

CreateOS supports a fixed set of framework slugs. If your detected framework has no slug, omit the framework field and rely on useBuildAI: true (Pattern A) or runtime + buildCommand + runCommand (Pattern B) instead.

Detected	settings.framework	Notes
Next.js	nextjs
React SPA (CRA, Vite React static)	reactjs-spa
React SSR	reactjs-ssr
Vue SPA	vuejs-spa
Vue SSR	vuejs-ssr
Nuxt	nuxtjs
Astro	astro
Remix	remix
SvelteKit / Svelte	omit	Use Pattern A (useBuildAI: true) or Pattern B with runtime: "node:20"
Angular	omit	Build to static, set buildCommand: "ng build" + buildDir: "dist/<app>"
Vite (generic, non-React/Vue)	omit	Use Pattern A, or Pattern B with runtime: "node:20"
Pure static export	omit framework	Use Pattern A with runtime: "node:20" and port: 80. Do NOT use runtime: "static" for type: "vcs" projects — it is rejected. runtime: "static" only works for type: "upload" projects

Runtime mapping (settings.runtime):

Read .nvmrc or package.json engines.node, then map to the closest supported runtime:

Source value	settings.runtime
Node 18.x	node:18
Node 20.x	node:20
Node 22.x	node:22
No version pinned	node:20 (current LTS default)
Static-only (no server)	node:20 (with useBuildAI: true) — not static for VCS projects

If the user's .nvmrc pins an unsupported version (e.g., Node 16), surface this and ask whether to upgrade to node:20.

Step 4: Migrate environment variables

This is the highest-risk step. Handle with care.

1. Ask the user to paste their Vercel env var list (names only, NOT values) OR upload the .env.vercel.backup file.
2. Show them the list and confirm which variables should be migrated. Some Vercel-injected vars do NOT need migration:
   • VERCEL_* vars — these are Vercel-specific runtime vars and are not needed on CreateOS.
   • VERCEL_URL, VERCEL_ENV, VERCEL_REGION — handled differently by CreateOS.
3. For each remaining variable, ask the user to provide the value (do NOT log or persist these values in the skill output).
4. Call UpdateProjectEnvironmentEnvironmentVariables to set them on the production environment.
5. Remind the user to mark sensitive values (API keys, tokens, database URLs) as sensitive in the CreateOS dashboard for encryption at rest.

Security note to surface to the user: If any Vercel environment variables were exposed during the April 2026 Vercel security incident, advise the user to rotate those credentials at the source (e.g., regenerate API keys in the issuing platform) before setting them on CreateOS.

Step 5: Handle Vercel-specific dependencies in code

Scan for and flag these patterns in the codebase. Do NOT auto-rewrite code unless the user explicitly approves.

Pattern	Action
@vercel/kv import	Flag for replacement with ioredis or redis pointed at CreateOS Valkey
@vercel/postgres import	Flag for replacement with pg or postgres pointed at CreateOS PostgreSQL
@vercel/blob import	Flag for replacement with S3-compatible client
@vercel/analytics import	Safe to remove or leave; no CreateOS replacement needed
@vercel/speed-insights import	Safe to remove; use Amplitude or similar if needed
runtime: 'edge' in route config	Flag — will run as standard Node on CreateOS
middleware.ts with edge runtime	Flag — will run as standard Node middleware

Produce a summary of required code changes and ask the user whether they want the skill to generate a migration branch with these changes, or whether they will handle them manually.

Step 6: Trigger the first deployment

1. Call TriggerLatestDeployment to kick off the first build.
2. Poll GetDeployment status until the build completes (or fails).
3. If the build fails:
   • Call GetBuildLogs to retrieve logs.
   • Summarize the failure for the user.
   • Suggest likely fixes based on common Vercel-to-CreateOS migration issues (see references/common-issues.md if bundled).
4. If the build succeeds, report:
   • The CreateOS deployment URL as returned by the API response (do NOT construct or guess the URL; use the exact url field from GetDeployment). The default subdomain pattern is https://[project].createos.nodeops.network, but always defer to the API's returned value.
   • Build duration
   • Deployment ID for reference

Step 7: Domain handoff (guided, not automated)

Do NOT cut over DNS automatically. Walk the user through domain migration manually.

1. Ask if they want to configure a custom domain now.
2. If yes, call CreateDomain with their domain.
3. Surface the DNS records they need to configure at their DNS provider (not at Vercel).
4. Advise them to:
   • Test the CreateOS deployment thoroughly at the createos.nodeops.network subdomain first.
   • Lower their DNS TTL at the current provider to 300 seconds 24 hours before cutover.
   • Keep the Vercel deployment live until the CreateOS deployment is verified.
   • Cut DNS over only when ready.
   • Keep the Vercel deployment active for at least 72 hours post-cutover as a fallback.

Step 8: Post-migration checklist

Produce a final report for the user covering:

• First deployment succeeded on CreateOS
• All environment variables migrated and tested
• Vercel-specific dependencies flagged (and resolved if applicable)
• Custom domain configured (if requested)
• DNS cutover plan understood
• Concierge support contact shared for complex issues

Share these resources:

• Docs: https://nodeops.network/createos/docs/deploy
• Migration guide: https://nodeops.network/createos/docs/Migrations/Vercel
• Concierge migration (for projects that need white-glove support): mailto:[e-mail]

---

Failure modes and rollback

If the migration fails at any step and the user wants to abort:

1. The CreateOS project can be deleted with DeleteProject — no charges are incurred for a project that never successfully deployed.
2. The user's Vercel deployment is untouched throughout this workflow. Nothing in this skill modifies Vercel resources.
3. Offer the concierge migration path as a fallback for complex projects.

---

What this skill does NOT do

Be explicit with the user about these boundaries:

• Does not modify or delete anything on Vercel.
• Does not automatically rewrite application code that uses Vercel-specific SDKs — only flags them.
• Does not perform DNS cutover — the user must do this intentionally.
• Does not migrate data from Vercel KV, Postgres, or Blob — data migration requires separate tooling.
• Does not migrate Vercel team members or access controls.
