For marketplaces of design assets

Sell design assets under licenses that hold.

Kiln is a managed marketplace platform for digital creative assets — UI kits, templates, icons, illustrations, mockups, graphics — sold under license tiers and delivered by entitlement-gated download. Designer onboarding, split payments, gated payouts, refunds that revoke, and moderation baked in.

No setup fees Stripe powered Instant delivery

Designers selling on Formfield, the live demo

Powerful features. Simplified.

Built for every player in your marketplace

Three surfaces on one codebase — buyers, designers, and operators each get their own.

For buyers

A beautiful shopping experience

  • Search with typeahead, format & license filters
  • Tier comparison, previews & favourites
  • Secure Stripe checkout
  • Instant download to a library, with a license certificate

For designers

A studio, not a spreadsheet

  • Self-serve Stripe onboarding
  • Archives inspected, versioned & delivered
  • License tiers, sales log & refunds
  • Downloads, revenue & payout ledger

For operators

Total control, zero hassle

  • Commission rules & versioned license templates
  • Review mode, reports & moderation
  • GMV, downloads & a health scorecard
  • White-label branding
Automate. Split. Scale.

The money splits itself.

Set your commission once and every license sale is a Stripe destination charge: the buyer pays, the platform keeps its fee, the designer's share lands in their own account. No code. No manual work. No spreadsheets.

Destination charges + application feePayouts gated by KYC

Payout breakdown

Buyer pays
CHF 48.00
Commercial license · the demo catalog's median tier price
Platform fee — 10%
CHF 4.80
Designer receives
CHF 43.20

Nothing else is charged — the fee is taken on the license price only, and the buyer's download is unlocked the moment the payment settles. Funds arrive on Stripe's standard payout schedule.

Four guarantees, each with a test behind it

Digital delivery, done right.

The split is right

Fee and share are computed by pure code and hold on every order row: subtotal equals fee plus share. The money suites are unchanged from the physical-goods engine.

Entitlement-gated delivery

Every asset byte reaches a buyer only through a signed, short-lived URL minted after an entitlement check. One module signs; a grep gate proves no second path exists.

Refunds revoke

A full refund or a lost dispute revokes the license inside the same transaction that projects the money; a partial refund keeps access. Tested against the webhook projections.

The spine stands alone

Discovery, studios, licensing display and moderation never import entitlements, the gate or the library. A seam guard test enforces the list on every run.

AI on every surface

AI drafts, the designer's files set the facts.

Every AI feature proposes; a person clicks to accept. Nothing is written without a human — nothing is invented, and nothing can't be traced back.

Human in control

AI proposes. You decide. You click. We save.

Built on trust

Grounded, validated, and never writes to your data.

The three pillars of trust

1. The Fence

AI proposes, a human clicks.

No AI feature writes to the database. Drafts, chips, proposals only — you click to make it real.

2. Honesty

Grounded, never invented.

Only what's visible or provided. No guessing, no made-up facts — stubs instead of speculation.

3. Trust Boundaries

Validated in, validated out.

Model output re-validated, uploads ownership-checked, other people's text fenced as data.

Generative & agentic features

Embeddings & semantic search

Same rules. Every surface. Every time. Because trust isn't a feature — it's the foundation. Bring your own keys; without them every AI affordance disappears and the marketplace runs identically.
