Custom Gutenberg Block Development
Editorial-first block libraries that let marketing ship pages without filing tickets.

01 What it is
What this service is
Custom Gutenberg block development is the practice of designing and building bespoke React-powered blocks for the WordPress block editor, so editorial and marketing teams can compose pages from a library of pre-approved, design-system-true components — without writing markup or filing developer tickets.
At devinsta we build block libraries in TypeScript using @wordpress/scripts, the block.json metadata format, and the InnerBlocks pattern. We pair them with block patterns (composed multi-block layouts) and full-site editing templates so the editor experience matches the brand system end to end.
02 What it's for
What it's for
You need a custom Gutenberg block library when marketing is being throttled by engineering — when every new landing page, campaign, or article variant requires a developer to ship HTML. Block libraries unlock the team: marketing composes pages from blocks, design controls the system, engineering controls the contract.
We also see this engagement during a rebrand or design-system rollout, when the visual language is changing and every block needs to be rebuilt to match.
03 How to use it
How to engage devinsta
Discovery establishes the inventory — which blocks are needed today, which patterns will recur, what the editor flow should feel like. We then design each block in Figma against the live design system, build them in TypeScript, and ship a block library plugin that can be installed across one or many sites.
Most engagements run 4–8 weeks. We train the editorial team during the final week so adoption begins immediately on handover.
04 How to deploy
How we deploy it
Block libraries ship as a WordPress plugin, version-controlled in GitHub, with CI running PHPCS, ESLint, and the @wordpress/scripts test runner. We deploy via Composer to managed WordPress hosts (WP Engine, Pantheon, Pressable, Kinsta) or via the WordPress VIP pipeline for enterprise tiers.
Versioning is explicit — minor releases for non-breaking changes, major releases for block schema changes that require a migration. We provide a deprecation policy and migration scripts (`wp db query`) for every breaking change.

FAQ
Common questions
Why custom blocks instead of ACF or Bricks?
Custom Gutenberg blocks live in the same editor experience as core WordPress, render server-side (good for SEO), and don't lock you into a builder vendor. ACF Blocks are a fine middle ground; page builders like Bricks or Elementor are usually a downgrade for any team serious about performance and accessibility.
Can we use this on multiple WordPress sites?
Yes — we ship blocks as a portable plugin. Multisite networks and single sites consume the same plugin. We also support Composer-based installs for VIP-style infrastructure.
What about full-site editing (FSE) themes?
We build FSE-compatible blocks and ship theme.json configurations so the same design tokens drive the editor sidebar, the frontend, and the global styles UI.
