300%
faster vs default WP REST
Measured on basic WordPress hosting in internal benchmark runs.
API ACCELERATOR
Turn WordPress into
JSON delivery on CDN
Smooth API Accelerator for WordPress keeps WP as your content source, then shifts repeated API delivery to prepared JSON files served through Smooth CDN.
30%
faster vs WP REST + extra cache
API Accelerator remained ahead even with additional REST caching enabled.
Less load
on WordPress server
Static JSON reads reduce repeated dynamic execution in WordPress.
From WP REST to cached JSON
This plugin is not about exposing one more endpoint. It turns repeated WordPress API reads into a CDN-served JSON delivery layer.
Step 1
Keep WordPress as the source
Your content workflow stays in WordPress and WP REST remains the original source of truth.
Step 2
Publish JSON files
The plugin turns selected WP REST responses into prepared JSON files ready for delivery.
Step 3
Move delivery to CDN
Frontends and apps read from Smooth CDN instead of repeatedly hitting WordPress for the same payload.
Delivery controls
Start with a simple WP REST to JSON flow, then shape payloads and access rules around the frontend you are actually building.
Blocks when needed
Expose structured block data when the frontend needs layout-aware content, not just rendered HTML.
Lean payloads
Publish only the fields clients actually use, so the delivery layer stays faster and easier to work with.
Protected feeds
Lock selected outputs behind token access when some JSON should not be public.

Guest is a special account type for testing dedicated plugins and custom integrations. Free is the regular self-serve plan for personal projects, experiments, and ongoing use.
Move WordPress API delivery to CDN
Keep publishing in WordPress, but let frontends read prepared JSON files from Smooth CDN instead of hammering the origin.
