POLOTNO SDK VS FABRIC.JS
Polotno SDK vs Fabric.js – schema editor vs canvas framework
Developer comparison of Polotno SDK and Fabric.js across purpose, integration, automation, rendering, features, industries, and pricing.
Polotno SDK embeds a full editor with a JSON schema; Fabric.js is a canvas framework for building drawing tools. Use Polotno when you want an in‑product editor with automation and export. Use Fabric.js when you want to assemble your own editor from canvas primitives.
ㅤ
Core philosophy
Polotno SDK is about shipping an editor quickly and unifying manual editing with automation in one schema. Rendering can run in the browser, on your servers, or via the Polotno Cloud Render API. Plans are on Request API key.
Fabric.js is about flexible canvas abstractions; the editor, templates, automation, and export are up to you.
ㅤ
Architecture and integration
Polotno SDK integrates as a browser editor with configurable UI and assets. Rendering paths are interchangeable under one schema: browser, self‑hosted, or cloud. For element control, see the video element, image element, and text element.
Fabric.js integrates as a rendering and interaction layer that you compose into an editor if needed.
ㅤ
Automation and templating
Polotno SDK exposes elements in JSON for code‑driven generation, variable mapping, and reusable [templates](https://polotno.com/docs/templates
).
Fabric.js provides objects and events; templating and automation require custom code.
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.
Fabric.js renders in the browser; server‑side rendering and video require additional systems.
ㅤ
Feature scope
Polotno SDK
Editor UI, templates, timeline, animation
Multi‑format export and flexible rendering
Fabric.js
Canvas objects, transforms, serialization helpers
No built‑in editor UI, templates, or export service
ㅤ

Feature comparison
Capability | Polotno SDK | Fabric.js |
|---|---|---|
Primary model | Embeddable editor + JSON schema | Canvas framework |
Editor inside your app | Yes (customizable UI) | No (you build it) |
Automation | Programmatic via schema and code | Custom implementation |
Rendering modes | Browser, self‑hosted, cloud | Browser canvas |
ㅤ
Pricing and licensing
Polotno SDK
Polotno SDK is licensed as a self‑hosted, embeddable SDK. Self‑Serve license starts at $899. Enterprise licensing is a custom quote that typically starts in the low five figures. Pricing scales based on integration criticality and commercial surface area, not number of users. See Request API key.
Fabric.js
Open‑source library; any editor, automation, or rendering pipeline is built by you.
ㅤ
Conclusion
Polotno SDK delivers an editor and schema‑based automation with flexible rendering. Fabric.js offers a canvas foundation when you want to craft the entire editor yourself.
