Glyph vs react-pdf for PDF Generation

When building React applications that generate PDFs, react-pdf has been a popular choice for its React-native approach to document construction. Glyph takes a fundamentally different philosophy: template-based documents with AI-powered customization, requiring zero layout code.

This guide provides an objective comparison to help you choose the right tool for your use case.

Code Complexity Comparison

Generating a Simple Invoice PDF

Glyph

// Generate a polished invoice in seconds
const response = await fetch('https://api.glyph.you/v1/create', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer gk_your_api_key',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    template: 'invoice-clean',
    data: {
      invoice: { number: 'INV-001', date: '2024-01-15' },
      client: { name: 'Acme Corp', email: 'billing@acme.com' },
      lineItems: [
        { description: 'Consulting', quantity: 10, unitPrice: 150, total: 1500 },
        { description: 'Development', quantity: 20, unitPrice: 125, total: 2500 }
      ],
      totals: { subtotal: 4000, tax: 360, total: 4360 }
    }
  })
});

const { url } = await response.json();
// Done. Professional PDF hosted at `url`

react-pdf

import React from 'react';
import { Document, Page, Text, View, StyleSheet } from '@react-pdf/renderer';

// First, define all your styles
const styles = StyleSheet.create({
  page: { padding: 30 },
  header: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    marginBottom: 20
  },
  title: { fontSize: 24, fontWeight: 'bold' },
  invoiceInfo: { textAlign: 'right' },
  clientSection: { marginBottom: 20 },
  table: { display: 'table', width: '100%' },
  tableRow: { flexDirection: 'row', borderBottom: 1, borderColor: '#eee' },
  tableHeader: { backgroundColor: '#f0f0f0', fontWeight: 'bold' },
  tableCell: { padding: 8, flex: 1 },
  tableCellDescription: { flex: 3 },
  totals: { marginTop: 20, alignItems: 'flex-end' },
  totalRow: { flexDirection: 'row', width: 200 },
  totalLabel: { flex: 1 },
  totalValue: { width: 80, textAlign: 'right' }
});

// Then build the document structure
const Invoice = ({ data }) => (
  <Document>
    <Page size="A4" style={styles.page}>
      <View style={styles.header}>
        <Text style={styles.title}>INVOICE</Text>
        <View style={styles.invoiceInfo}>
          <Text>{data.invoice.number}</Text>
          <Text>{data.invoice.date}</Text>
        </View>
      </View>

      <View style={styles.clientSection}>
        <Text style={{ fontWeight: 'bold' }}>Bill To:</Text>
        <Text>{data.client.name}</Text>
        <Text>{data.client.email}</Text>
      </View>

      <View style={styles.table}>
        <View style={[styles.tableRow, styles.tableHeader]}>
          <Text style={[styles.tableCell, styles.tableCellDescription]}>Description</Text>
          <Text style={styles.tableCell}>Qty</Text>
          <Text style={styles.tableCell}>Rate</Text>
          <Text style={styles.tableCell}>Amount</Text>
        </View>

        {data.lineItems.map((item, i) => (
          <View key={i} style={styles.tableRow}>
            <Text style={[styles.tableCell, styles.tableCellDescription]}>{item.description}</Text>
            <Text style={styles.tableCell}>{item.quantity}</Text>
            <Text style={styles.tableCell}>${item.unitPrice}</Text>
            <Text style={styles.tableCell}>${item.total}</Text>
          </View>
        ))}
      </View>

      <View style={styles.totals}>
        <View style={styles.totalRow}>
          <Text style={styles.totalLabel}>Subtotal:</Text>
          <Text style={styles.totalValue}>${data.totals.subtotal}</Text>
        </View>
        <View style={styles.totalRow}>
          <Text style={styles.totalLabel}>Tax:</Text>
          <Text style={styles.totalValue}>${data.totals.tax}</Text>
        </View>
        <View style={styles.totalRow}>
          <Text style={[styles.totalLabel, { fontWeight: 'bold' }]}>Total:</Text>
          <Text style={[styles.totalValue, { fontWeight: 'bold' }]}>${data.totals.total}</Text>
        </View>
      </View>
    </Page>
  </Document>
);

// Then render it
import { pdf } from '@react-pdf/renderer';
const blob = await pdf(<Invoice data={invoiceData} />).toBlob();

Lines of code: Glyph ~15 vs react-pdf ~80+ (and Glyph’s template is pre-designed)

Modifying Document Styles

Glyph

// User wants a more modern look
const response = await fetch('https://api.glyph.you/v1/modify', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer gk_your_api_key',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    sessionId: 'session-id',
    prompt: 'Make the design more modern with a navy header, clean sans-serif fonts, and subtle gray line separators'
  })
});

// AI applies comprehensive style changes automatically
const { html } = await response.json();

react-pdf

// You need to manually update every style property

const styles = StyleSheet.create({
  page: {
    padding: 30,
    fontFamily: 'Helvetica' // Limited font options
  },
  header: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    marginBottom: 20,
    backgroundColor: '#1e3a5f', // Manual: add navy background
    padding: 15,               // Manual: add padding
    color: 'white'             // Manual: change text color
  },
  title: {
    fontSize: 24,
    fontWeight: 'bold',
    color: 'white'             // Manual: update for contrast
  },
  // ... update every other style manually
  tableRow: {
    flexDirection: 'row',
    borderBottom: 1,
    borderColor: '#e5e5e5'    // Manual: subtle gray
  },
  // What about "more modern"? That's subjective.
  // react-pdf can't interpret design intent.
});

// Every style change requires:
// 1. Code modification
// 2. Re-build
// 3. Re-deploy

The difference: Glyph understands design intent and applies comprehensive changes. react-pdf requires explicit property-by-property updates.

Providing End-User Customization

Glyph

<!-- Drop-in component for user editing -->
<script src="https://sdk.glyph.you/glyph.min.js"></script>

<glyph-editor
  api-key="gk_your_key"
  template="invoice-clean"
  :data="invoiceData">
</glyph-editor>

<!-- Users can:
  - Click any section to select it
  - Type "make this blue" or "add my logo here"
  - See changes in real-time
  - Download final PDF
  All with zero additional code.
-->

react-pdf

// react-pdf generates PDFs but provides no editing UI.
// You would need to build:

// 1. A preview component (react-pdf/renderer can show in browser)
import { PDFViewer } from '@react-pdf/renderer';
<PDFViewer><Invoice data={data} /></PDFViewer>

// 2. A complete editing interface
const [styles, setStyles] = useState(defaultStyles);
const [content, setContent] = useState(defaultContent);

// 3. Color pickers, font selectors, spacing controls...
<ColorPicker value={styles.header.backgroundColor} onChange={...} />
<FontSelect value={styles.page.fontFamily} onChange={...} />
<SpacingControl value={styles.page.padding} onChange={...} />

// 4. Logic to map UI changes to StyleSheet updates
// 5. State management for undo/redo
// 6. Save/export functionality

// This is 500-1000+ lines of code minimum.
// And users still can't describe changes in natural language.

The difference: Glyph provides complete end-user editing with natural language. react-pdf is render-only.

When to Use react-pdf

react-pdf remains the right choice when you need:

• Pure React ecosystem - You want everything in JSX/React components
• Programmatic layouts - Layouts are computed dynamically from complex logic
• No external dependencies - Everything runs in your Node.js process
• Tight React integration - You’re already using react-pdf in production
• Complex component reuse - You have intricate React component hierarchies
• Client-side generation - PDFs must be generated in the browser

Tip

react-pdf excels when your document structure is truly dynamic and computed from code. If your documents follow templates with variable data, Glyph is simpler.

When to Use Glyph

Glyph is the better choice when:

• Templates over code - Your documents follow predictable structures
• Non-developers customize - End-users should modify documents without coding
• Speed to production - You want PDFs working today, not next week
• AI-native editing - Natural language modifications are valuable
• Design quality - You need professional templates without design expertise
• Framework agnostic - You’re not using React, or want API-based generation
• Maintenance burden - You don’t want to maintain layout code

Migration Guide: react-pdf to Glyph

Step 1: Identify Your Document Types

List the types of documents you generate:

// Before: Multiple react-pdf components
const Invoice = ({ data }) => <Document>...</Document>;
const Quote = ({ data }) => <Document>...</Document>;
const Receipt = ({ data }) => <Document>...</Document>;

Map these to Glyph templates (use built-in or create custom).

Step 2: Extract Data Schemas

From your react-pdf component props, create JSON schemas:

// Your react-pdf component
const Invoice = ({
  client,      // { name, email, address }
  lineItems,   // [{ description, quantity, price }]
  totals       // { subtotal, tax, total }
}) => ...

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "required": ["client", "lineItems", "totals"],
  "properties": {
    "client": {
      "type": "object",
      "properties": {
        "name": { "type": "string" },
        "email": { "type": "string" },
        "address": { "type": "string" }
      }
    },
    "lineItems": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "description": { "type": "string" },
          "quantity": { "type": "number" },
          "price": { "type": "number" }
        }
      }
    },
    "totals": {
      "type": "object",
      "properties": {
        "subtotal": { "type": "number" },
        "tax": { "type": "number" },
        "total": { "type": "number" }
      }
    }
  }
}

Step 3: Convert Layout to HTML Template

Transform your react-pdf components to HTML with Mustache:

// Before (react-pdf)
<View style={styles.header}>
  <Text style={styles.title}>INVOICE</Text>
  <Text>{data.invoice.number}</Text>
</View>

{data.lineItems.map((item, i) => (
  <View key={i} style={styles.row}>
    <Text>{item.description}</Text>
    <Text>${item.price}</Text>
  </View>
))}

<!-- After (Glyph template) -->
<div class="header" data-glyph-region="header">
  <h1>INVOICE</h1>
  <span>{{invoice.number}}</span>
</div>

{{#lineItems}}
<div class="row" data-glyph-region="line-item">
  <span>{{description}}</span>
  <span>${{price}}</span>
</div>
{{/lineItems}}

Step 4: Move Styles to CSS

Convert StyleSheet objects to CSS:

// Before (react-pdf)
const styles = StyleSheet.create({
  header: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    padding: 20,
    backgroundColor: '#f5f5f5'
  }
});

/* After (CSS in template) */
.header {
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  padding: 20px;
  background-color: #f5f5f5;
}

Step 5: Upload and Use

# Upload custom template
curl -X POST https://api.glyph.you/v1/templates \
  -H "Authorization: Bearer gk_your_api_key" \
  -F "name=my-invoice" \
  -F "template=@./template.html" \
  -F "schema=@./schema.json"

// Replace generation code
// Before
const blob = await pdf(<Invoice data={data} />).toBlob();

// After
const response = await fetch('https://api.glyph.you/v1/create', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer gk_your_api_key',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ template: 'my-invoice', data })
});
const { url } = await response.json();

Step 6: Add End-User Editing (Bonus)

With Glyph, you can now offer something react-pdf never could:

<glyph-editor
  api-key="gk_your_key"
  template="my-invoice"
  :data="invoiceData"
  @glyph:ready="onEditorReady"
  @glyph:generated="onPdfGenerated">
</glyph-editor>

Users can now customize their documents with natural language.

Cost Comparison

Factor	Glyph	react-pdf
Library cost	API pricing ($0-129/mo)	Free (MIT license)
Development time	Hours	Days to weeks
Design expertise	Not required (templates)	Required (build layouts)
Maintenance	Zero (SaaS)	Ongoing (your code)
End-user editing	Included	Build from scratch

Note

react-pdf is free software, but factor in development time for building layouts, maintaining code, and (if needed) building editing UIs. Glyph’s subscription often costs less than the developer hours saved.

Summary

Choose Glyph if your documents follow templates, you want AI-powered customization, you need end-user editing, or you want to ship fast without writing layout code.

Choose react-pdf if you need everything in React components, your layouts are highly dynamic/computed, you want zero external dependencies, or you have significant existing react-pdf investment.

Both tools generate PDFs. Glyph is template-first with AI superpowers. react-pdf is code-first with React ergonomics. Choose based on whether your documents are template-based or programmatically constructed.
