Excited to release our new WordPress plugin product for caching REST API requests.
We built Frosty Cache to remove the performance bottlenecks WordPress hits when serving the REST API to decoupled frontends — including eCommerce, for the likes of WooCommerce. Our own need was specific: Headless WordPress running CoCart, our main product.
Instead of caching in the database like most REST cache plugins, Frosty Cache stores responses as static JSON files and serves them before WordPress even connects to the database — about 14ms per cache hit, 10–15x faster than database-based alternatives.
What’s in v1.0.0
- Pre-database serving via an
advanced-cache.phpdrop-in - ETag generation with
If-None-Match/ 304 Not Modified support - Smart invalidation — only affected files are purged, never a full flush
- WooCommerce and CoCart compatibility modules
- 18+ hooks and filters for full cache lifecycle control
- WP-CLI commands:
flush,clear-post,clear-route,status,warm,repair, and more
Full reference is in the documentation.
