rn-upgrade-doctor: React Native Upgrade Helper CLI

rn-upgrade-doctor is a command-line tool that makes React Native version upgrades faster, safer, and more predictable. Whether you’re moving between minor versions or taking a big jump to the latest React Native release, it helps you plan and carry out the upgrade without the usual trial and error.

Why React Native upgrades are painful

Every React Native upgrade means dealing with breaking changes, deprecated APIs, native project changes in the iOS (Xcode, Podfile, CocoaPods) and Android (Gradle, AndroidManifest) folders, and third-party libraries that may not support the new version yet. Most teams put upgrades off because the cost is hard to estimate. They end up running outdated React Native versions with security, performance, and App Store or Google Play compliance risks. rn-upgrade-doctor is built to take the guesswork out of that process.

What it helps you do

• Plan a React Native version upgrade before you touch your codebase

• Understand what changes between your current version and your target version

• Spot dependency and compatibility issues early, including npm and yarn packages that may block the upgrade

• Handle native iOS and Android project changes with more confidence

• Cut the time and risk of migrating to the latest React Native version, including the New Architecture (Fabric, TurboModules) and Hermes

• Keep your React Native app current, secure, and release-ready

Who it’s for

• React Native developers and mobile engineers maintaining production apps

• Engineering teams and agencies managing several React Native projects

• Tech leads who need to estimate, schedule, and de-risk upgrade work

• Startups and enterprises that want a repeatable React Native upgrade process

• Freelancers and consultants who deliver React Native maintenance and migration work

Why developers use it

• A CLI-first workflow that fits your terminal, CI/CD pipelines, and existing React Native tooling

• Works with bare React Native projects and complements the official React Native Upgrade Helper

• Saves hours of manual diffing, reading changelogs, and fixing build errors after an upgrade

• Supports a steadier upgrade cadence, so you stop falling many versions behind

• Designed for real-world apps, not toy projects

Built by a React Native engineer

rn-upgrade-doctor was created by a senior software engineer with 11+ years of experience in React Native, Swift/iOS, and mobile app development, including large-scale mobile banking applications. It started as an open-source project and is now being developed further under Mobilixir Technologies, a mobile and web development consultancy.

What’s next

The CLI launched on 20 October 2026. A full web portal is planned for 9 November 2026, extending the tool with a richer, more visual upgrade experience for individuals and teams. Early users can shape the roadmap, so feedback and feature requests are very welcome.
