Verdict in one paragraph

Astro is the modern answer; Gatsby is the legacy answer. For new projects in 2026 the choice is straightforward — Astro. Gatsby has been declining since 2023 and the framework that filled its conceptual space (Jamstack-flavoured static sites with an opinionated content layer) is now Astro, not Gatsby. Existing Gatsby sites do not need to migrate urgently but should plan for one.

Score across the criteria: Astro 5 · Gatsby 0

Decision criteria

  • Which is the right pick for a new project?

    Astro

    Astro. Gatsby is in soft decline; new bets should not be placed there.

  • Which is faster on the page?

    Astro

    Astro ships zero JavaScript by default. Gatsby ships React hydration on every page. The Lighthouse delta is real.

  • Which has a healthier maintenance trajectory?

    Astro

    Astro has an active core team and rapid feature pace (Server Islands, Content Layer, View Transitions). Gatsby is slower since the Netlify acquisition.

  • Which is easier to migrate to from WordPress?

    Astro

    Astro's Markdown, MDX, and Content Collections handle WordPress imports cleanly. Gatsby plugins exist but feel dated.

  • Which is the safer 5-year bet?

    Astro

    No reasonable read of the 2026 market suggests Gatsby will out-grow Astro over the next five years.

What Astro is best for

  • Marketing sites and landing pages where Core Web Vitals matter
  • Documentation, blogs, and content hubs
  • Programmatic SEO at scale (HostList: 25k pages, Deluxe Astrology: 91k pages)
  • Multi-framework teams sharing a single static site
  • Migration off WordPress when content is structured cleanly

What Gatsby is best for

  • Existing Gatsby sites with no compelling reason to migrate
  • Teams that already know the Gatsby + GraphQL data layer
  • Sites where the plugin ecosystem has a piece you cannot easily replace
