Portable Build

Answer a checklist about how your AI-generated app was built — framework, code access, hosting, documentation, and team continuity — grouped by category, and get a weighted portability score with a breakdown of what would block migrating it off its original platform.

  • Weighted scoring across 5 portability categories
  • Highlights your top migration blockers, worst first
  • All answers stay in your browser
Framework & code

Built on a standard, widely-used framework

e.g. React, Next.js, Rails, Django — not a proprietary visual-only builder format.

Generated code is human-readable, not obfuscated

You (or any developer) can open the source files and understand the logic.

App does not depend on a proprietary runtime/component library

Platform-specific UI blocks or runtime APIs that only work inside the original builder.

Code access

Full source code can be exported or downloaded

A complete, working export of the codebase, not just a read-only preview.

Code is (or can be) pushed to your own Git repository

You control a git history independent of the platform's internal versioning.

Hosting

App can run on standard hosting (any cloud/VPS)

Not locked to the platform's own hosting — could be deployed to Vercel, AWS, a VPS, etc.

Database is a portable, standard engine

Postgres, MySQL, SQLite — not a proprietary data store you can only access through the platform.

Custom domain and DNS are fully under your control

Domain and SSL are not tied to a platform-specific subdomain you cannot leave.

Documentation

Basic architecture/setup documentation exists

A README or equivalent explaining how to run, build, and deploy the app outside the platform.

Environment variables and config are documented

A new developer could reconstruct the required config without reverse-engineering the platform.

Team & continuity

A developer outside the original builder/agency could pick this up

The app doesn't depend on tacit knowledge that only lives with the person who prompted it.

Ongoing costs are not tied to a single vendor subscription

The app doesn't stop working the moment you cancel the platform subscription.

How it works

1

Answer the portability checklist

Rate each item across framework/code, code access, hosting, documentation, and team continuity as Yes, Partial, or No.

2

We calculate a weighted portability score

Each item is weighted by how important it is to leaving the original platform, giving a transparent 0-100 score and a tier from vendor locked-in to fully portable.

3

See your top migration blockers

The five weakest, highest-weight gaps are surfaced first so you know exactly what would stop you moving this app off its original platform today.

Frequently asked questions

Does this scan my actual app or platform account?

No — this is a self-assessment checklist. It scores portability purely from the answers you provide and runs entirely in your browser; it does not connect to any platform or codebase.

What counts as a proprietary platform lock-in?

Anything that only works inside the original builder — a visual-only component format, a runtime API unique to the platform, a database you can only access through it, or hosting/billing you cannot leave without losing the app.

Why are code access and hosting weighted so heavily?

Without exportable source code and the ability to run on standard hosting, no amount of documentation makes an app truly portable — those two categories are the hard technical floor for leaving a platform.

Is a low score a dealbreaker?

No — it is a starting point for a hardening plan. Many AI-generated apps start locked-in and become portable once source is exported to your own repo and moved to standard hosting.

How is this different from Production Ready AI style checklists?

Portable Build asks specifically whether you could leave the original platform and keep running the app elsewhere — a distinct question from whether the app itself is ready for real user traffic.
