Direct Checkout works with the tools stores already use.
- Cache plugins: checkout and cart pages are excluded automatically from LiteSpeed Cache, WP Rocket, W3 Total Cache, WP Super Cache, SiteGround Optimizer, Autoptimize, Cloudflare, Kinsta and Nginx Helper.
- Page builders: Elementor, Divi and Bricks product templates get Buy Now after the description; the shortcode places it anywhere.
- HPOS: declared compatible with WooCommerce High-Performance Order Storage.
- Payment gateways: direct checkout and Buy Now use the normal WooCommerce checkout, so every gateway keeps working. The popup is for cash on delivery.
- Speed: a module that is off adds no hooks and sends no CSS or JavaScript.
