Astro 7's Rust compiler promises 15–61% faster builds. One developer's got slower. (astro.build)
The rewrite runs deep. The rendering engine is about 2.4x faster, and Astro moves to Vite 8 with the new Rolldown bundler, which the team clocks at 10-30x faster than Rollup. Several sites now build more than twice as fast as on v6.
But the thread caught the asterisks. Strict HTML compilation now errors on unclosed tags, which blocks upgrading any site that pulls in messy remote content. One developer reported builds that got slightly slower, not faster. And the engineer who wrote the new Rust compiler is in the thread, taking questions.
