Pros

• Blazing‑fast builds powered by esbuild, delivering roughly 50x faster build times than Rollup‑based tools, making iteration near‑instantaneous.
• Zero‑config defaults that "just work" for most TypeScript library authors, providing the best default experience with excellent developer experience.
• Produces clean, minimal bundle output that is easy to reason about, without the unnecessary overhead and complexity sometimes added by direct esbuild usage.

Cons

• Less flexible than directly using esbuild for highly custom, non‑standard bundling scenarios where fine‑grained control over every build step is required.
• Tree‑shaking capabilities are good but not as superior as unbuild's, which may matter for libraries where bundle size is ultra‑critical.
• Relies on esbuild's plugin ecosystem; if a required esbuild plugin is immature or missing, workarounds can be challenging.
