Conclusion ## References ## Data Sources ## AI Tools ## AI Code Generation Platforms ## Framework Official Sources ## Specialized Libraries and Tools Why do AI platforms like v0, Lovable, and Bolt default to React? What does Svelte's AI optimization mean? Is Angular still worth considering? This article uses real data from January 2026 to analyze the competitive landscape of frontend frameworks in the AI era. In early 2026, when you open v0.app and type a sentence to generate UI, it outputs Next.js + React + shadcn/ui. When you use Lovable to build a product prototype, it's powered by TypeScript + React + Vite + Tailwind. When you're vibe coding on Bolt.new, although it supports multiple frameworks, React is still the default. Meanwhile, the Svelte official blog announced "AI works better now" and released the Svelte MCP tool. Angular upgraded to v21, featuring "supercharge your development with AI". This raises a question: How has the competitive landscape of frontend frameworks changed in the AI era? Data sources: npmtrends.com, GitHub, LinkedIn Jobs (January 2026) Tier 1: React Dominates Tier 2: Vue, Svelte, Angular Each Have Their Strengths Rising Players: Astro, Solid, htmx According to the Stack Overflow 2025 Developer Survey: The JetBrains 2025 Developer Ecosystem Survey collected feedback from 24,534 developers. Key Finding: v0 and Lovable only support React. While Bolt.new supports multiple frameworks, React is still the default. According to Vercel Blog: According to Next.js Blog: ThoughtWorks Technology Radar lists assistant-ui as a recommended "React library for AI chat interfaces." According to Svelte Blog, 2026 updates include: According to Angular official, v21 features: According to Astro Blog: Code volume on GitHub, Stack Overflow Q&A count, technical blog articles—React dominates across all dimensions. Result: AI models have a deeper understanding of React and generate higher-quality code. According to SWE-bench (late 2025 data): Performance differences across major frameworks haven't been publicly disclosed, but given the training data distribution, React code generation quality is likely higher. Don't choose React just because it has better AI support, but also don't ignore the huge impact of AI on development efficiency. Evaluation should be based on: Choosing a frontend framework in 2026 is no longer just about "syntax preference" or "performance comparison." AI, as the developer's "invisible teammate," is changing the weight of technology selection criteria. When choosing a tech stack, ask yourself: "To what extent can AI help me with this framework?"
