Printess is a web-to-print platform: a template designer, a buyer editor you embed in your shop, and print-file rendering, all on its cloud. Polotno SDK is a design editor SDK you install in your own app, with print export included and rendering you can host yourself. Both put an editor in front of shoppers and end in a print-ready PDF. One question decides it: do you want a finished print personalization product, or an editor you build your own product around?
Pick the one that matches what you're building
Pick Printess if…
- You sell personalized print and want no servers to run: Printess hosts the editor, templates and rendering, and plugs into Shopify, WooCommerce, Magento and Shopware.
- You sell photo products: it builds for them, with photobook tools, collage layouts, and photorealistic and 3D previews.
- Your products need finishing: Printess says it supports foil, embossing, laser engraving and DTF, and shows each finish in previews.
- Your print workflow already exists: its larger plans import InDesign files and connect to HP SiteFlow and Kornit X.
Pick Polotno SDK if…
- The editor is part of your own product: Polotno ships as React components in your bundle, and you compose the interface in your own code.
- You need to host it yourself: every license includes self-hosted editing and rendering. Printess describes itself as fully cloud-based.
- You want designs as files you own: a design is documented JSON you store, version and generate from code.
- Print is one output among several: the same editor and design format also cover social graphics, presentations and video.
How Printess and Polotno differ
1. Who runs the system
Printess calls itself "fully cloud-based". The editor loads from its servers, templates sit on its AWS storage, and its pipeline renders the print files. Your customer, order and payment data stay with you. For a custom interface, its headless component lets your team write the UI against a JavaScript API, while the core stays on Printess's cloud. You run no servers, and you rely on Printess for uptime, which it states as 99.999%.
Polotno ships in your bundle and renders through the optional Cloud Render API, on your own servers, or in the browser. Cloud Render is the quickest route, with no servers to run. Design content reaches Polotno servers only if you use Cloud Render or AI features. License checks and the default asset panels carry no design content. Self-hosting makes rendering operations your job, and it lets you choose where designs live, including restricted networks.
2. Print-product depth
Printess ships more for print commerce out of the box. Flexible layouts fit one design to many products and sizes. Mockups, 3D previews and photobook tools come finished. Output covers CMYK and spot colors with ICC profiles and die-cut lines, and previews show finishes such as foil and embossing. On an SDK, you would build the product side of that yourself.
Polotno covers the print file: CMYK, bleed, crop marks, PDF/X-1a and PDF/X-4, spot colors and overprint, plus a preflight tool. Magic resize moves and scales elements to fit a new size. You compose the rest: mockups come from your product photos or your print partner's API, and product logic lives in your code. Polotno has no imposition, cut lines, or print catalog. Web-to-print companies such as Momentu and Peleman made that trade for more control, and the web-to-print page maps the pieces.
3. Shops and print workflows
Printess has plugins for Shopify, WooCommerce, Magento and Shopware, and an optional module connects orders to HP SiteFlow and Kornit X. We found no website, cart or print fulfillment service from Printess, so you bring your own.
Polotno gives you a Shopify route for your own app or storefront, and integration guides for print partners such as Printful, Gelato and Lulu. You write that integration yourself. If a working plugin matters more to you than control, Printess is ahead here.
4. Templates and data
You author Printess templates in its design backend and store them in its cloud. One template can offer forms, a graphical editor, or both. If you plan a large library, ask Printess about export routes before you commit.
Polotno designs are JSON you store, version and generate from code. Your code sets values in that JSON for personalization and batch rendering. Per-element locks and admin, user and viewer roles control what a buyer can change. Import covers PDF, SVG, PPTX, PSD in beta, plus Figma frames through SVG.
5. Output and languages
Printess says its focus is online personalization, and it outputs PDF, JPEG, PNG and TIFF.
Printess says it can't be localized into right-to-left languages such as Hebrew and Arabic. Polotno applies right-to-left direction on the canvas and carries it through PDF, SVG and HTML export.
6. Pricing model
Printess sells subscriptions that include order credits each month, with overage on top. One credit covers a document of up to 4 pages, and larger plans lower the rate per credit. Modules, AI, mockups and extra storage add to the bill. Printess charges for production files, so edits that never become an order cost nothing. See Printess pricing.

When Printess is the right call
If you run a print shop or a personalized-products store and you want buyers designing soon, Printess is the shorter path. You skip server operations, you get mockups and photobook tooling from the start, and Printess says you can ideally go live within 30 to 60 days. It publishes its plans, so you can model the cost yourself.
Polotno fits when the editor is part of a platform you own, when designs must stay on your side, or when print is one output among many. A reasonable rule: if you'd describe your business as "we sell printed products," start with Printess. If you'd describe it as "we build software with a design editor in it," start with Polotno.
