Sliday is a digital marketplace run by a New Zealand-based design studio that's been around since 2009. They sell a wide range of downloadable assets: design kits for Ionic apps, illustration builders, gradient styles, eBook templates, browser components, and even music packs for various genres. If you're building a mobile app or website, you'll find ready-made UI elements for Sketch, Figma, and Adobe XD. There's also a plugin that generates AI faces as placeholder images, plus a handful of management templates for running meetings or tracking project checklists.

What makes Sliday stand out is the sheer variety and the focus on practical, reusable assets. Their Ionic Design Kit, for example, includes components, icons, and screens that match the Ionic framework – handy if you're prototyping a cross-platform app. The Illustration Builder lets you swap parts to create custom characters. And the music packs are organized by mood (travel, education, action, etc.), so content creators can grab royalty-free background tracks quickly. Most products come with free demo versions, so you can test before buying.

Who is this for? Freelance designers, product teams building with Ionic or Figma, project managers who need FigJam templates, and video editors looking for simple background music. Sliday doesn't try to be an all-in-one platform – it's just a curated shop selling things that its own team has actually built and used. If you're after a quick UI kit for your next app or a set of checklist templates, this is a straightforward place to browse.
