The short version

  • Only Rollup has a free tier, so it costs nothing to try first.
  • Each has a real cost: GitHub Copilot agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • They diverge on capability: GitHub Copilot covers Code completion, Rollup covers Tree shaking.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month

Rollup

  • Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
  • Configuration for non-trivial applications gets verbose compared with tools that assume more
