## About Polotno

The React design editor SDK you host yourself, with cloud rendering billed on top. Swap the Polotno SDK for Orshot Embed. Yourself, or we do it for you.

Comparing options first? Read the [Polotno alternative comparison](https://orshot.com/blog/polotno-studio-alternative.md).

## Steps

1. **Export:** Export each template from your current platform, one file each.
2. **Import:** Import it in New Template, then check the parameter names match your old ones.
3. **Swap the step:** Point your API call or Zapier, Make, n8n step at the Orshot template.
4. **Decide:** Run both, compare a few renders, then keep whichever works for you.

## What Orshot Embed gives you

### Design editor inside your own app

- **White-label design editor for your app (Orshot Embed):** every paid workspace can embed the Orshot editor in its own product with an iframe or the React and Vue components, so your customers edit templates right inside your app. It works as a design editor SDK, photo editor SDK and white label video editor in one, instead of building a Canva clone (from $39 a month). ([more](https://orshot.com/features/orshot-embed.md))
- **Programmatic control of the embedded editor:** listen to editor events for every save and download, get webhooks when users create, update or delete templates, drive the editor from your code, add your own toolbar buttons, and render every design through the API. Each end user gets a private template library behind JWT sessions, locked to your domains (from $160 a month, up to 1,500 end users). Teams use it as an IMG.LY alternative or Polotno alternative.

## Prompt for your coding agent

Paste this into Claude Code, Cursor, Codex or ChatGPT inside the project that uses Polotno:

    # Replace the Polotno SDK in this project with Orshot Embed
    
    You are helping me move this project off the Polotno SDK (the `polotno` npm package, `polotno-node` and api.polotno.com) and onto Orshot (orshot.com). Orshot runs the template editor for me: I embed it through an iframe or a React/Vue component, and Orshot's API renders images, PDFs and videos from the same templates. Orshot also has native n8n, Make, Zapier, Pipedream and Airtable apps and an MCP server (https://mcp.orshot.com/mcp, setup at https://orshot.com/agents). Connect to that MCP server first if you can: with it you can list my Orshot templates, read their parameters and run test renders. Read the linked docs before you change anything, then work through the steps in order.
    
    ## 1. List every place this project uses Polotno
    
    Search for, and list with file paths:
    - imports from `polotno`, `polotno/…`, `polotno-node`, `polotno/ui.css`
    - `createStore(`, `store.toJSON`, `store.loadJSON`, `store.on(`, `store.toDataURL`, `store.saveAsImage`, `store.saveAsPDF`
    - `<PolotnoContainer`, `<SidePanel`, `<Workspace`, `<Toolbar`, `<PagesTimeline`, custom side panel sections
    - `api.polotno.com` render calls and the Polotno key (env vars, `key:` in createStore)
    - code that stores or serves design JSON per user (database tables, S3 keys, API routes)
    - code that substitutes `{variable}` tokens in design JSON before rendering
    
    ## 2. Import the designs
    
    Designs cannot be converted from code alone. I will export each design as JSON (`store.toJSON()`, or the JSON export in Polotno Studio) and import it in Orshot myself (New Template → Polotno tab → paste the JSON, or bulk import up to 10 files on a paid plan). Guide: https://orshot.com/migrate/from-polotno · Importer docs: https://orshot.com/docs/importing-templates/import-from-polotno
    
    After import every text and image layer is an Orshot parameter with an automatic ID (`text_1_1`, `img_1_2`), which I can rename in the Studio.
    - Groups, animations, video layers, background images and image crops don't convert, and figure shapes other than circles become rectangles. Flag designs that use them; ungrouping before export keeps grouped layers. A video layer comes in as an image pointing at the video file and fails the image copy, so delete video layers before export.
    - A `{name}` token inside a text layer: in Orshot the whole layer is one parameter. Rename it, or change the token to `{{name}}` and send `"<parameterId>:name"`. Docs: https://orshot.com/docs/orshot-studio/inline-parameters
    
    Ask me for the Orshot template IDs, or read the parameters with:
    - GET /v1/studio/templates/{id}: https://orshot.com/docs/api-reference/studio-template-get
    - List templates: https://orshot.com/docs/api-reference/studio-templates-list
    
    Build a mapping table: Polotno design (file or DB row) → Orshot templateId, and Polotno `{variable}` → Orshot parameter name. Show it to me before editing code.
    
    ## 3. Replace the editor

    Polotno:
    ```jsx
    const store = createStore({ key: POLOTNO_KEY, showCredit: false });
    <PolotnoContainer><SidePanelWrap><SidePanel store={store} /></SidePanelWrap>
      <WorkspaceWrap><Toolbar store={store} /><Workspace store={store} /></WorkspaceWrap></PolotnoContainer>
    ```
    
    Orshot (plain HTML):
    ```html
    <iframe src="https://orshot.com/embeds/EMBED_ID?templateId=12345&userId=USER_ID" title="Editor" allow="clipboard-write" style="width:100%;height:100%;min-height:600px;border:none"></iframe>
    ```
    
    Orshot (React):
    ```jsx
    import { OrshotEmbed } from "@orshot/embed-react";
    <OrshotEmbed embedId="EMBED_ID" templateId={12345} />
    // Per-user libraries: use the iframe URL with &userId=… (the SDK props are embedId, templateId, modifications)
    ```
    
    Rules:
    - The embed ID comes from my Orshot workspace (Embed → Embed Code). Store it as `ORSHOT_EMBED_ID`. Remove the Polotno key, the `polotno` package, its CSS import and every Polotno component.
    - `store.loadJSON(json)` becomes the `templateId` query parameter. `?lang=` sets the language. Docs: https://orshot.com/docs/orshot-embed/integration
    - One store per user becomes the `userId` (plus optional `userName`, `userEmail`) query parameters; Orshot keeps each user's templates and brand library (images, videos, audio, colors, fonts) apart. Docs: https://orshot.com/docs/orshot-embed/per-user-data
    - Appearance is set in the dashboard (accent color, title, icon, language) and with the `hide` query parameter for panels (`templateBar,pagesBar,metaBar,toolsBar,videoBar,stylesSidebar,smartResize`). Docs: https://orshot.com/docs/orshot-embed/appearance
    - If the app runs on Safari or inside webviews, sign a JWT and pass it as `token`. Docs: https://orshot.com/docs/orshot-embed/jwt-authentication
    - Per-user action locks (upload, delete, create) go in the `permissions` claim of the JWT. Docs: https://orshot.com/docs/orshot-embed/user-permissions
    
    ## 4. Replace store events and exports
    
    Reference: https://orshot.com/docs/orshot-embed/events · Control: https://orshot.com/docs/orshot-embed/controlling-embed · Custom buttons: https://orshot.com/docs/orshot-embed/custom-buttons · Asset picker: https://orshot.com/docs/orshot-embed/custom-asset-picker
    
    - `store.on('change', …)` and your own save endpoint become the `orshot:template:create` / `orshot:template:update` postMessage events plus a webhook URL set in the dashboard. Orshot stores the design; keep only the template ID in my database.
    - `store.toDataURL()` / `saveAsImage()` / `saveAsPDF()` become downloads inside the embed, or a custom toolbar button that emits the PNG/PDF to the parent window (`orshot:custom_action`).
    - `store.loadJSON()` at runtime becomes an `orshot:embed:control` message with `templateId`; setting element text or images becomes the same message with `modifications`.
    - A custom side panel that lists my own assets becomes the Custom Asset Picker: answer `orshot:asset:request` with `orshot:asset:response`.
    - Always check `event.origin` includes `orshot.com`.
    
    ## 5. Rewrite the render calls
    
    Reference: https://orshot.com/docs/api-reference/render-from-studio-template
    
    Polotno:
    ```http
    POST https://api.polotno.com/api/renders?KEY=…
    { "design": { …full JSON with {variables} already substituted… }, "format": "png", "pixelRatio": 2 }
    ```
    
    Orshot:
    ```http
    POST https://api.orshot.com/v1/studio/render
    Authorization: Bearer ORSHOT_KEY
    { "templateId": 12345, "modifications": { "headline": "Hello", "photo": "https://…" }, "response": { "type": "url", "format": "png" } }
    ```
    
    Rules:
    - The design stays in Orshot. Send only `templateId` and `modifications` keyed by parameter name. Delete the JSON substitution code.
    - Style overrides use dot keys: `"headline.fontSize": 48`, `"headline.color": "#111"`. Docs: https://orshot.com/docs/dynamic-parameters
    - Multi-page templates prefix the page: `"page2@headline"`.
    - `response.format`: png, jpg, webp, avif, pdf, mp4, webm, gif. `response.type`: url, base64, binary.
    - Sync is the default and returns `data.content`. For a webhook use `"mode": "async"` inside `response` plus top-level `webhook_url`; you get `202 { id, status: "queued" }` and can poll GET /v1/studio/render-jobs/{id}. Docs: https://orshot.com/docs/api-reference/async-render-start
    - Remove `polotno-node`, Puppeteer and the Chromium layer from the server, Dockerfile and CI.
    - Auth is Bearer. Store the key as `ORSHOT_API_KEY`. Keys: https://orshot.com/docs/quick-start/get-api-key
    - Official SDKs (Node, Python, Ruby, PHP): https://orshot.com/docs/sdks · Errors: https://orshot.com/docs/error-reference
    
    ## 6. Automations
    
    If a Zapier, Make or n8n step calls Polotno, add the Orshot step next to it with the same parameters, run it once, then remove the old step. Ready-made workflows are in Quick Connect (Copy as n8n workflow / Make blueprint). Docs: https://orshot.com/integrations
    
    ## 7. Verify, then switch
    
    Put the Orshot embed behind a feature flag next to the Polotno editor. Open the same design in both, save from Orshot, confirm the webhook and postMessage events arrive, render each template once from the API and compare with the Polotno output. After a week of matching results, remove the Polotno code and the key. Tell me what you removed.
