{"slug":"best-frontend-build-tool-for-bundling","title":"Best frontend build tool for bundling","question":"What are the best frontend build tool for bundling?","verdict":"As of 2026-07-10, ChatGPT, Claude, Gemini and Grok collectively rank Vite #1 for frontend build tool for bundling on ModelsAgree — a unanimous pick. The models' case: Best overall developer experience, huge ecosystem, near-zero configuration, excellent HMR, and Vite 8’s Rolldown-powered unified pipeline delivers dramatically faster. The models' main caveat: Make bundled development mode stable and default so very large applications stay consistently fast. The strongest alternative is Rspack — Rust-native speed, strong code splitting and Module Federation, persistent caching, and the smoothest migration path for large webpack applications.
