Vite 8 Shipped Rolldown. Linear's Builds Went From 46 Seconds to 6.

Vite 8 just released and Linear's builds reduced from 46 seconds to 6. It's not wrong. Same codebase, same plugins, same CI. Just swapped the bundler. The culprit? Rolldown 🦀 The culprit? Rolldown. A Rust-based bundler that replaces both esbuild and Rollup in one shot. The context goes like this. Vite has effectively had a split personality since day one. esbuild for dev, Rollup for prod. Two tools, two behaviors, two bug surfaces. Every single Vite user has hit that bug where something works in dev and breaks in prod. Different tree-shaking. Different chunk splitting. Different everything. Vite 8 wipes that out. Dev and prod are both Rolldown now. One bundler, one pipeline, one behavior. The numbers are absurd 📊 According to the Vite team's benchmarks, Rolldown is 10 to 30x faster than Rollup while matching esbuild's speed. → Linear saw an 87% reduction in build times (46s → 6s) → Ramp reported 57% faster builds → Mercedes-Benz.io cut theirs by 38% These aren't synthetic benchmarks.
