Features
Unblock the main thread. Unleash your speed.
Third-party scripts are the #1 killer of page speed. Quickload defers them until they actually matter — using a tiny 3KB runtime with no code changes required.
Crush Core Web Vitals
Defer the scripts that drag down LCP, INP, and TBT — the metrics Google ranks against. Real before/after numbers, not lab tricks.
Built for Lighthouse
Quickload aligns with Google's SEO and performance audits by eliminating render-blocking and unnecessary main-thread work.
Tag-safe by design
We defer the original <script> tag — currentScript.src, integrity, async/defer all preserved. Your vendor scripts behave normally.
No code, no headaches
Activate the WordPress plugin, pick a trigger, save. Quickload detects every cross-origin script and handles it for you.
Connect the tools you use
Tested with GTM, GA4, Meta Pixel, LinkedIn, Hotjar, Hubspot, Marketo, Pardot, 6sense, RB2B, Drift, Klaviyo, and more.
Real humans behind it
Pro support from people who run perf engineering at agencies. Talk to us when something gets weird.
