    Why ImgSlider?

    Other comparison nodes only work locally. ImgSlider gives you a link you can share anywhere - Reddit, Discord, your portfolio, client reviews. One click to publish, instant shareable URL.

    Features

    • Shareable Links: Publish and get a URL to share your comparison anywhere
    • No Account Required: Create sliders instantly (expire after 30 days)
    • Inline Preview: See the comparison directly in your workflow node
    • Link in Node: The published URL appears right inside the node — no need to check the console
    • One-Click Publishing: Toggle publish, run workflow, get link
