How to contribute — and why it sells

Vs Next.js — scale

  • Next: 3k contributors, bot triage, slow review.
  • Vesk: ~12 active, human review, commit-level feedback.
  • Your PR is read by the parser author, not a bot.

Vs Svelte/Astro — depth

  • Astro: content-first, runtime thin.
  • Svelte: runtime-first, compiler helps.
  • Vesk: compiler-is-the-product — IR shared to Kotlin.
