Duply

Duply solves the version problem in visual marketing: every campaign wants the same approved design with a different headline, price, offer, name or product shot.

Instead of reopening a design tool for each variation, you build one branded template, mark which layers your data is allowed to change, and let Duply render the rest.

Data can arrive from a REST API call, a dynamic URL, a CSV file, a submitted form, or a Zapier and Make workflow, which makes the platform a practical middle layer between campaign data and visual output.

Where marketers feel it fastest is personalization at volume: a shop sending segmented email promotions can generate a different hero image per segment without a designer in the loop, and paid teams can spin up price-drop, countdown and audience-specific ad variants in minutes rather than days.

One standard image costs a single credit, and the official FAQ confirms direct generation, forms, REST API calls, integrations and dynamic URLs all follow the same output-based credit rules.

The trade-offs are honest: Duply is a young indie product, the free entry is a one-time starter balance rather than a recurring free tier, and included subscription credits reset every billing period, so high-volume teams should budget for the Business tier or non-expiring top-up credits.
