Upgrades shouldn't feel like archaeology

Teams moving from Angular v19→20→21 lose days chasing breaking changes, peer dependency conflicts, zoneless compatibility gaps, and deprecated APIs. Official update guides help, but they miss the messy reality in your dependency tree.

NgReady turns your package.json into an actionable checklist in seconds — entirely in your browser, with nothing uploaded to a server.

How it works

Three steps from package.json to a migration plan you can share with your team.

  1. Step 1

    Paste your package.json

    Drop in a single app manifest or upload monorepo workspace files. Your data stays client-side.

  2. Step 2

    Run an instant scan

    NgReady checks 60+ Angular-specific rules for version breakers, peer deps, and deprecated tooling.

  3. Step 3

    Act on the checklist

    Get a compatibility score, prioritized findings, ng update commands, and copy-paste fix snippets.

Built for real Angular migrations

Hyper-focused rules for the issues that actually slow teams down during v19→20→21 upgrades.

Peer dependency conflicts

Catch Material, CDK, NgRx, and third-party packages that drift out of sync with @angular/core.

Zoneless readiness

Spot missing or outdated zone.js setups before you commit to experimental change detection.

Deprecated APIs & tooling

Surface legacy packages like Protractor, TSLint, and @angular/http before they block your upgrade.

Fix suggestions

Copy ng update commands and migration snippets tailored to npm, yarn, or pnpm.
