Kittl

Kittl is a Berlin-based, browser-based graphic design platform positioned for commerce-driven creative workflows — "Canva is for content, Kittl is for commerce." It serves small business owners, Shopify and Etsy sellers, print-on-demand businesses, DTC brands, freelancers, agencies and small creative teams, covering branding, packaging, product imagery, marketing campaigns, merchandise, labels, mockups and digital assets with AI-assisted creative workflows. For developers, Kittl runs an app/extension platform: sandboxed web apps run in an isolated iframe inside the Kittl editor and integrate with editor APIs over postMessage through the official @kittl/sdk JavaScript SDK, governed by a declared scope set in manifest.json and shipped through the @kittl/cli toolchain. The platform is in beta and account approval is required to create apps.

Kittl publishes 1 API on the APIs.io network. Tagged areas include Company, Design, Graphic Design, Creative Tools, and SDK.

Kittl’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 25 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/kittl: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The Kittl SDK is the bridge between a sandboxed app and the Kittl editor host. It exposes async namespaces
    — kittl.design for design operations, kittl.state for editor and app state, kittl.upload for image uploads, kittl.data
    for the font and mockup catalogs, kittl.ai for credit-metered generation, and kittl.auth for OAuth helper flows. Every
    call returns an SdkResult envelope ({ isOk, result, error }). Access is governed by a static scope set declared in manifest.json
    config.scopes and enforced by the host at call time. Apps are packaged and released through the Kittl CLI against an immutable,
    admin-reviewed version.
