UI Kits & Design Systems on Attesar

New listings are reviewed and published daily. Figma, Sketch and Adobe XD kits, design systems, wireframe libraries and icon sets. Every seller here is identity-verified, every listing is reviewed before publication, and your payment is protected until you confirm delivery.

Variables, auto-layout and components

A kit built with Figma variables, auto-layout and proper variants adapts to your brand in minutes. Static frames only look similar; they must be rebuilt to be useful. The listing states which one you are getting.

Fonts and imagery inside the kit

Kits must use free or included fonts and disclose any stock imagery. If the kit shows a premium font, the seller must say so and you will need your own licence for it.

Dark mode and accessibility

Check whether dark mode is a real token set or a separate file, and whether colour contrast meets accessibility guidance. Serious kits document both.

Verified sellers

Government ID and selfie verification before anyone can list.

Protected payment

Held by our payment partner until you confirm delivery.

Fair disputes

Open a dispute before confirming; staff review the evidence.

Rights and safety

Buying and selling UI kits safely

What to check before money moves, and what you must be able to prove before you list.

If you are buying

Read the licence before you pay. The licence named on the listing is the whole of what you are buying — a commercial licence is not an extended one, and neither transfers ownership. If the scope is unclear, ask in the deal chat so the answer is on the record.
Test everything before you confirm delivery. Confirming releases the money and closes the escrow. If the files are incomplete, do not match the listing, or the licence differs from what was advertised, open a dispute instead of confirming.
Keep the invoice and the deal chat. They are your evidence of what was promised, what was delivered, and on what terms.
You may use what you bought under the stated licence. You may not resell, redistribute or relist the asset itself, or pass it to another party as your own work, unless you bought exclusive rights.

If you are selling

You must be the author, or hold a written licence that permits resale. Attesar verifies who you are, not what you own — if a rights-holder proves otherwise, the listing is removed, the sale is reversed, and repeat cases end the account.
Describe exactly what is included and what is not. Most disputes here are not fraud; they are a buyer who expected the demo content, the fonts, or the support that was never actually part of the package.
Keep your proof of ownership. Source files, commit history, purchase receipts for anything third-party, and the licences that let you redistribute it. You may be asked for them, and having them ready is what turns a complaint into a closed ticket.
Set the licence deliberately. It is what the buyer is paying for, and it binds you as much as them — an exclusive sale means you stop selling that item to anyone else.

What goes wrong specifically with UI kits

Demo images, icons and fonts are rarely included

Buyer: Photos, icon sets, fonts and audio shown in a preview are usually licensed to the author alone and cannot be passed on. Assume you must replace or separately license them before launch unless the listing states in writing that redistribution rights are included.
Seller: You may only redistribute third-party assets when the licence explicitly permits it. Standard stock licences do not. Either buy a redistribution licence, or ship placeholders and list exactly what the buyer must supply. Naming the assets you did not create protects you as much as the buyer.

Font licences are narrow and scope-specific

Buyer: A font is not "buy once, use anywhere". Check the number of seats, webfont pageview caps, whether app and ebook embedding are allowed, and whether you may convert formats. Typeface names and designs can be protected independently of the software file.
Seller: You must own the outlines or hold a licence permitting resale. Do not sell modified copies of licensed fonts, close imitations of protected typefaces, or files converted from a desktop-only licence. Include your EULA in the package and state desktop, web, app and embedding scope in the listing.

Disclose AI-generated work

Buyer: Purely AI-generated material may attract thin copyright protection or none at all in your country, which affects whether you can stop anyone else using the same asset. If that matters, ask the seller for a written statement of what was AI-generated before you buy.
Seller: Say so in the listing if any part was AI-generated. You must still hold the right to sell the output, and prompts that name a living artist, a studio style or an existing brand can produce infringing results. Undisclosed AI generation is grounds for removal.

UI kits — frequently asked questions

Which tools are supported?

Mostly Figma, plus Sketch, Adobe XD and Penpot. Each listing states the tool, component count and whether auto-layout and variables are used.

Can I use a kit in client work?

Yes, with a commercial licence. You cannot resell the kit or publish it as your own.

Are the fonts included?

Sellers must use free fonts or include them. If a premium font is shown, the listing says so and you will need your own licence.

How is a kit delivered?

As a downloadable file or a Figma community/duplicate link, unlocked once your payment is protected.
