Description:

Swift Performance is a caching and speed optimization plugin for WordPress. Version 2.3.7.3 uses AI to optimize site speed with a focus on real user experience and field data. It keeps a good content to code ratio and optimizes images in an SEO friendly way, because speed optimization is a cornerstone of SEO.

The plugin targets the Core Web Vitals metrics. For Largest Contentful Paint it preloads important images and fonts and delays less important resources. It optimizes javascript parsing and execution even for logged in users and non-cacheable pages to reduce First Input Delay. It optimizes javascript, CSS and fonts for real users, not only for testing tools, to reduce Cumulative Layout Shift. Critical CSS and intelligent preloading lower First Contentful Paint, including on mobile devices with a poor connection. Further techniques improve Interaction to Next Paint, and preloading, caching and advanced support for third party tools keep Time to First Byte low.

Swift Performance is aimed at bloggers, webshops and freelancers. Included features cover AI optimization, critical CSS and JS optimization, free image optimization, WooCommerce support, a Support Center and regular updates. The AI version can configure itself automatically, and documentation is available for both the AI version and Swift 2.x. The plugin is a Must-Have Plugins product.

How It Works

Install the free EffectIO Dashboard plugin on your WordPress site. It connects to the EffectIO catalog, detects every premium plugin and theme you own, and gives you a single hub to manage licenses, run updates, and keep your admin panel clean — all from one screen.

⚡

One-Click Updates
Update any premium plugin or theme instantly. No manual downloads, no FTP — just click "Update Now."

🔑

License Manager
View, activate, and manage all your license keys in one place. No hunting through emails or vendor dashboards.

🔇

Notification Blocker
Blocks intrusive admin nag screens, upsell banners, and ads that clutter your dashboard. Re-enable anytime.

🛡️

Vendor Request Control
Prevents redundant license-check pings to third-party servers for items you already manage through EffectIO.

📦

Bulk Activation
Club members can activate all eligible plugins and themes at once — one button, zero hassle.

🆓

100% Free
The Dashboard itself costs nothing. Install it and it auto-activates on your domain — no key required.

Get Started in 3 Steps

1

Download & Install

Download the EffectIO Dashboard zip and install it via Plugins → Add New → Upload.

2

Browse & Activate

Open EffectIO → Catalog in your admin panel. The dashboard auto-detects your installed items and matches them to your licenses.

3

Update & Manage

Keep everything current with one-click updates. Manage licenses, block nag notices, and enjoy a cleaner WordPress experience.

Licenses

All WordPress derivative work is GPL-licensed. Most items are pre-activated and ready to use. Some require an activation key — we provide it with your purchase, and the Dashboard lets you apply it in seconds.

Club members enjoy bulk activation: activate every eligible item at once with a single click. No more entering keys one by one.

✅ Money-Back Guarantee

Every item is tested and ships with full features. If something doesn't work and we can't fix it, you get a full refund. We believe premium tools should be accessible — that's why we offer a low-cost subscription so freelancers, small businesses, and agencies can grow without a large upfront investment.
