Swish: Page Speed Booster

Slow pages and incomplete product data cost you sales. Swish speeds up your storefront with a theme app embed that delays non-critical third-party scripts, lazy loads offscreen images and videos, preloads your main image and adds resource hints. Turn it on from the theme editor, no code needed. Swish also scores how well AI shopping agents like ChatGPT, Gemini and Perplexity can read your store and gives you a prioritized fix list. App impact analysis and Safe Mode rollback are included.
