I was investigating today which internationalization package to use. The Next.js docs page lists several options to consider. Each has pros and cons (according to Perplexity): Pros: Middleware routing, TypeScript-first, great dev tools, production-ready
Cons: Learning curve, less flexible for custom setups
Pros: Zero-config setup, simple API, excellent DX
Cons: Younger project, smaller community
Pros: Clean URL routing, SEO-optimized, lightweight
Cons: Manual translation handling required
Pros: Compile-time safety, tiny bundles, blazing fast
Cons: New ecosystem, fewer integrations
Pros: ICU message format, CLI extraction, framework-agnostic
Cons: JSX macro setup, more configuration
Pros: Visual translation editor, in-app editing, headless
Cons: Paid tiers for scale, vendor dependency
Pros: Edge runtime support, streaming-friendly
Cons: Early development, limited documentation
Pros: AI-powered translations, quick setup
Cons: Relies on external translation service
Pros: Mature ecosystem, huge plugin library
Cons: Heavy bundle, complex Next.js config
I'm leaning toward i18next - its mature ecosystem and strong maintenance make it appealing. It should be reasonably easy to install and set up according to these pages:
