Rendria

Rendria is a tool for generating marketing visuals from templates and data. It turns content into ready-to-publish banners, social posts, ads, and blog thumbnails, with a stated focus on on-brand output and production images at scale.

Its visual template editor lets users design and fine-tune dynamic templates by placing text, images, and layers where they want them, then saving and reusing those templates. Through the API, any layer can be modified programmatically: text can be updated, images replaced, colors changed, or elements toggled. Rendria also includes a Playground for experimenting with real templates and JSON requests, with renders shown instantly so changes can be tested before integration.

The service supports .png, .jpg, and .webp exports, and says renders are produced at high fidelity and ready to publish without manual post-processing. Its workflow is described as designing a template once, connecting via the API, and then generating many on-brand images automatically for social, ads, and blog posts. Delivery is via API, the visual editor, and the Playground. The site says new users receive 30 free credits on sign up, with no credit card required, an instant API key, and pay-as-you-scale pricing.
