Citatly lets you manage your own quote collection and automatically displays a fresh one each day on your website — cache-safe, without any external services or API keys.
The daily quote is selected based on the current date, so every visitor sees the same quote throughout the day regardless of caching. It is delivered via a REST API endpoint with proper HTTP caching headers, making it fully compatible with full-page caches and CDNs like WP Rocket, LiteSpeed Cache, or Cloudflare.
