Svelte Split Testing

Run Split Tests (or A/B tests) with the power of Svelte(Kit). Split tests (or A/B tests) allow you to display different features or variants to test their effectiveness. Unfortunately popular options are very pricey, bloated, and don't work SSR. This package attempts to remedy all of that.

This package works with Svelte and SvelteKit.

• Works SSR
• Works with or without Kit
• Works with GTM and GA4, or any other analytics solution
• Lightweight
• Free, of course
