Build Fixes & Debugging
Gatsby builds break — dependency conflicts, GraphQL schema changes, plugin incompatibilities, Node.js version issues. We diagnose and fix build failures fast, whether it’s a one-off fix or an ongoing maintenance need.
GatsbyJS Support & Development
GatsbyJS Support From Developers Who’ve Built on It for Years.
Build fixes, component development, headless CMS integrations, performance optimization, and migration planning — from developers who know Gatsby’s GraphQL data layer, plugin ecosystem, and build pipeline inside and out.

Full-scope GatsbyJS support.
Component Development
New React components, page templates, and layout systems built within Gatsby’s component architecture. We work with Gatsby’s page creation API, dynamic routing, and file-system-based routing.
Headless CMS Integration
Gatsby source plugins for Sanity, Contentful, WordPress, Drupal, and other headless CMS platforms — configured, customized, and maintained. GraphQL schema customization and source plugin debugging.
Performance Optimization
Image optimization with gatsby-plugin-image, code splitting, lazy loading, prefetching configuration, and Core Web Vitals improvements. Gatsby sites should be fast — we make sure they are.
Gatsby Migration
Migration from Gatsby to Astro, Next.js, or another modern framework — with full SEO preservation, URL mapping, and content migration. We know what to carry forward and what to leave behind.
CI/CD & Build Pipeline
Build pipeline configuration, deployment setup, incremental builds, and build time optimization. We work with Netlify, Vercel, Cloudflare Pages, and custom CI/CD setups.
Emergency Break-Fix
Production build failures, deployment issues, runtime errors — we diagnose and fix fast. Available to retainer and ad hoc clients.
Dependency Updates
Gatsby’s dependency tree is deep. We manage major version upgrades, plugin updates, and Node.js version migrations — tested and verified before deployment.
The Gatsby landscape in 2026.
Where Gatsby stands
Gatsby is still running production sites. They still need support.
Gatsby Cloud shut down, Netlify acquired the project, and the framework’s future is uncertain. But thousands of production sites still run on Gatsby — and they still need bug fixes, dependency updates, CMS integration maintenance, and performance optimization. If your site is on Gatsby and you’re not ready to migrate, you need a developer who actually knows the framework, not someone learning it on your dime.
The dependency challenge
Gatsby’s dependency tree is a maintenance burden.
Gatsby pulls in hundreds of npm packages — and as the ecosystem evolves, dependency conflicts become more common. Node.js version upgrades break plugins. Gatsby plugin authors abandon their packages. GraphQL schema changes in your CMS cascade into build failures. Managing these dependencies requires someone who understands Gatsby’s architecture and can trace issues through its build pipeline.
Planning ahead See our migration service →
When migration makes sense — and when it doesn’t.
Not every Gatsby site needs to be migrated immediately. If your site is stable, performing well, and meeting your needs, continued maintenance may be the right call. But if you’re hitting build time issues, dependency walls, or need features that Gatsby doesn’t support well, planning a migration to Astro or Next.js is worth discussing. We can help you evaluate both paths honestly.
How we work
Getting started with Gatsby support.
1
Site & Build Audit
We review your Gatsby site — version, plugin inventory, dependency health, build times, CMS integration, and deployment setup. You get a clear picture of what’s working, what’s fragile, and what needs attention.
2
Engagement Setup
We define the scope — retainer hours for ongoing maintenance, or project scope for specific work. Retainer clients get a dedicated communication channel and defined response times.
3
Ongoing Support or Project Delivery
Dependency updates, build fixes, component development, CMS integration maintenance, and performance optimization — worked through systematically on retainer, or delivered as a fixed-scope project.
4
Migration Planning
For clients considering a move off Gatsby, we provide honest assessment of timing, effort, and target platform — and can execute the migration when you’re ready.
