Gatsby
Gatsby built a large share of the React content sites still running today, and most guides here are written for the teams who maintain one. The question they face is rarely which generator is best in general; it is whether to stay, and if not, where to go and how to get there without breaking URLs or losing search traffic.
Two comparisons measure the realistic destinations on real sites — Astro with React islands, and Next.js static export for teams that want React-first pages — on build time, JavaScript shipped, field Core Web Vitals and dependency health. The migration guides then cover the hard part, which is not the components but Gatsby's GraphQL data layer, and the SEO checks that keep a migration from costing rankings.
Choosing the Right Static Site Generator for Production
- Gatsby vs Astro for Content Sites in 2026ComparisonGatsby and Astro compared for content sites today: build time, JavaScript shipped, Core Web Vitals, ecosystem health and the cost of moving.
- Next.js Static Export vs Gatsby for Existing React SitesComparisonFor a React team on Gatsby, compare staying with Gatsby against moving to Next.js static export: build time, page weight, ecosystem health and migration effort.
- Migrating from Gatsby to AstroHow-toMove a Gatsby content site to Astro: replace GraphQL queries with content collections, port React components as islands, and keep image quality and URLs.
- Migrating from Gatsby to Next.js Static ExportHow-toA concrete recipe for moving a Gatsby content site to a Next.js static export — GraphQL data layer to file reads, plugins to libraries, with measured build and bundle deltas.
- Replacing Gatsby GraphQL Queries During a MigrationHow-toInventory every Gatsby GraphQL query, map each to plain data functions or content collections, and migrate page by page with output checks.
