Kittl positions itself as a browser-based design editor aimed at Etsy sellers, small business owners, and freelance designers who need polished output without a steep learning curve. The template library and AI generation tools cover the bulk of POD use cases — t-shirts, posters, logos — fast. The ceiling appears when designs require precise multi-layer control or when teams need API access to plug Kittl into a larger production pipeline: neither exists. There is no self-hosted option and no API, so any workflow automation has to live outside the tool. Teams that outgrow the canvas export assets and finish in Illustrator.
