Duply
Generate, Edit, Scale and Manage Images and Videos Smarter & Faster.
About Duply
Duply is a developer platform for generating images and videos from templates. Templates are created and managed as separate metadata and variant-document resources, with each template supporting multiple variants (sizes or layouts). Content is produced either through asynchronous render jobs submitted via a REST API, or through query-parameter-based render URLs that apply variable values directly to a template before rendering.
The platform offers a REST API v2 using bearer API key authentication, scoped access (templates:read, templates:write, renders:read, renders:write, usage:read), cursor pagination, idempotency keys, and asynchronous job polling, documented via an OpenAPI 3.1 contract. A legacy REST API (v1) and an original API remain supported for existing integrations, including Basic authentication, binary-UUID template identifiers, and prior response formats. Render URLs support format conversion (jpg/jpeg/png), transparency, and both query-based and cryptographically signed access, with edge caching of completed renders.
Duply also exposes a stateless MCP server over Streamable HTTP, backed by the same API keys, scopes, and render queue as the REST API, allowing an AI client to list, inspect, create, and update templates and to create and check the status of renders. Official Zapier and Make apps are available, and the platform documents integration patterns for Zapier, Make, and n8n, recommending the v2 API with idempotency keys for new automation workflows.

Frequently asked questions
What integrations does Duply support?
Duply has official Zapier and Make apps, works with n8n via HTTP requests, and supports custom integrations through its REST API.
Can AI clients use Duply directly?
Yes, Duply exposes a stateless Streamable HTTP MCP endpoint using the same API keys and scopes as the REST API, with tools to list, create, and update templates and to create and check renders.
How does authentication work?
New integrations use scoped bearer API keys created in Account, while legacy integrations can keep using Basic authentication and original URLs.
Will my existing integration break if I don't migrate?
No, existing Zapier, n8n, Make, and custom integrations can keep using their legacy endpoints and authentication, though new workflows should use the v2 API with idempotency keys.
How are renders generated and cached?
Renders are asynchronous jobs polled until completion, and identical template, variable, and output combinations reuse the generated file, with completed redirects cached at the edge for five minutes.
