Polotno SDK embeds a customizable editor in your product; Toast UI Image Editor is a lightweight in‑browser image editor library. Choose Polotno when you need an in‑product editor with automation and rendering options. Choose Toast UI when you want a quick client‑side image editor without server dependencies.
ㅤ
Core philosophy
Polotno SDK focuses on a unified schema and full control inside your app. Projects are JSON, so manual editing and automation are two faces of the same model. Rendering can be local, self‑hosted, or via the Polotno Cloud Render API. Plans are on Request API key.
Toast UI Image Editor focuses on fast, browser‑only image operations with a minimal UI and no backend.
ㅤ
Architecture and integration
Polotno SDK integrates as a JavaScript editor with customizable UI, roles, and asset sources. Rendering paths are interchangeable under one schema: browser, self‑hosted, or cloud. For element granularity, see the image element and text element; video layers use the video element.
Toast UI Image Editor ships as a client‑side library you can drop into pages; it does not include server‑side rendering or automation.
ㅤ
Automation and templating
Polotno SDK supports schema‑driven generation from code, variable mapping from data, and AI‑assisted workflows, all renderable locally, self‑hosted, or in the cloud. Reusable templates help standardize layouts.
Toast UI Image Editor provides interactive tools (crop, resize, filters, annotations) but no schema‑level templating or batch automation.
ㅤ
Rendering and export
Polotno SDK supports PNG, JPEG, PDF, PPTX, GIF, and MP4 and can render in‑browser, self‑hosted, or via Cloud Render; see import and export for formats.
Toast UI Image Editor exports images in the browser; video and document exports are out of scope.
