Hey everyone! Thanks for checking out Boostify. The problem is simple: third-party scripts kill web performance. YouTube embeds, analytics, chat widgets, social plugins. They all load eagerly on the main thread and tank your Core Web Vitals. I kept running into this at the agency level. Clients would ask why their Lighthouse scores dropped, and the answer was always the same. Some embed or tracking script loading at the worst possible time. I wanted a lightweight toolkit that lets you defer and trigger resource loading based on actual user behavior. Scroll position, viewport visibility, click, idle time. Load what you need, when you need it. No heavy framework, no build step required. The approach evolved as I tested it across real client sites. Started as a simple lazy-loader for iframes, then grew into a more flexible system with multiple trigger types and support for injecting JS, CSS, and HTML content on demand. Node and UMD compatible so it works however your project is set up. It's free, open source, and honestly pretty small. That's the point. Would love to hear how you'd use it or what triggers you'd want to see next.
