Browser Automation Platform

Browserless

Browserless provides headless browser APIs for automation through a managed cloud service or a self-hosted Docker deployment. Developers can connect Puppeteer or Playwright over WebSocket, use Selenium, or call BrowserQL and REST APIs for scraping, screenshots, and PDFs. Its REST /pdf endpoint accepts either a URL or raw HTML and returns a binary PDF without requiring a browser library in your application. This comparison focuses specifically on the Browserless PDF API.

PDF Generation API

PDFBolt

PDFBolt is a managed Chromium PDF generation API for repeatable document workflows. It converts HTTPS URLs, Base64-encoded HTML, and published Handlebars templates with JSON data. AI can generate templates from prompts or reference files. Direct returns PDF data, Sync provides a temporary URL, and Async returns a request ID before sending a signed completion webhook. PDFBolt also supports S3‑compatible delivery, four compression levels, and PDF/X output with CMYK conversion and ICC profiles.

When PDFBolt Is the Better Fit
for PDF Generation

Managed templates, flexible delivery, compression, and print-ready output are built into PDFBolt.

Manage reusable templates from code

Use the Template API to create, validate, preview, compare, save, and publish reusable templates without opening the Dashboard Template Designer.

Design templates with live preview and AI

Start with a gallery layout, edit it with live preview, or use AI to create a first draft from a prompt and reference files.

Choose how each PDF is delivered

Use Direct for PDF bytes, Sync for a temporary download URL, or Async for background generation. Browserless's documented /pdf endpoint returns the file directly in the HTTP response.

Verify Async callbacks

PDFBolt signs every Async webhook with HMAC-SHA256. Configure retries for failed conversion attempts, then receive one callback when the conversion succeeds or all retries fail.

Compress PDFs as they are generated

Apply lossless, low, medium, or high compression while each PDF is generated. Browserless's PDF endpoint does not document a configurable compression option.

Generate print-ready PDFs

Generate PDF/X-1a or PDF/X-4 with RGB-to-CMYK conversion and FOGRA39, FOGRA51, SWOP, or GRACoL ICC profiles.

Browserless vs PDFBolt: A Closer Look

How the two platforms handle reusable document layouts, developer workflows, and PDF output.

Managing Reusable Document Layouts

Browserless

Browserless renders a URL or raw HTML and lets each request configure navigation, waits, authentication, cookies, headers, scripts, and styles. This works well when the application already owns the page or HTML. Reusable layouts stay in the application, which supplies the current URL or HTML for each render.

PDFBolt

PDFBolt stores reusable Handlebars templates and combines the published version with templateData for each API conversion. The Template Designer supports drafts, PDF previews, published versions, version history, and restoring an earlier version as a new draft. A template can start from scratch, from the template gallery, or from AI generation based on a prompt and reference files.

Developer Experience

Browserless

Browserless's stateless /pdf endpoint accepts a URL or raw HTML and returns a binary PDF in the same HTTP response. Its guides and OpenAPI reference include examples for cURL, JavaScript/Node.js, Python, Java, C#, PHP, Go, and Ruby. The OpenAPI-based REST API Playground lets you configure and run requests, inspect responses, and copy cURL commands. For more control over the browser, developers can use BrowserQL or connect with Puppeteer or Playwright.

PDFBolt

PDFBolt provides official SDKs for Node.js, Python, and PHP. REST Quick Starts cover Node.js, Python, PHP, Java, C#, Go, and Rust, with cURL examples and a Postman collection. The Template API lets applications, CI workflows, and AI coding agents such as Codex and Claude Code manage reusable templates programmatically. The Playground lets you configure and preview URL, HTML, or template conversions, then copy API code for the selected settings. PDFBolt also provides a verified n8n Community Node and integration guides for Make, Zapier, and other automation platforms. Direct returns PDF bytes, Sync returns a temporary URL, and Async returns an immediate request ID followed by a signed completion webhook. Sync and Async can upload directly to an S3-compatible bucket through a presigned URL.

PDF-Specific Features

Browserless

Browserless's /pdf endpoint supports PDF options based on Puppeteer's interface, including standard and custom page sizes, margins, landscape orientation, page ranges, background graphics, HTML header and footer templates, tagged PDFs, and document outlines.

PDFBolt

PDFBolt also supports standard page formats, custom dimensions, margins, orientation, HTML headers and footers, and background printing. It supports tagged PDFs and applies lossless, low, medium, or high compression as part of PDF generation. For commercial print, it can produce PDF/X-1a or PDF/X-4 output, convert RGB content to CMYK, and use FOGRA39, FOGRA51, SWOP, or GRACoL ICC profiles. Tagged output adds document structure but does not by itself guarantee PDF/UA conformance.

How to Migrate from Browserless to PDFBolt

Replace simple Browserless /pdf calls with PDFBolt Direct using a few API changes.

Node.js
Python
Java
C#
cURL

Browserless REST /pdf

import fs from 'fs';

const response = await fetch(
'https://production-sfo.browserless.io/pdf?token=YOUR_TOKEN',
{
method: 'POST',
headers: {
'Cache-Control': 'no-cache',
'Content-Type': 'application/json',
},
body: JSON.stringify({
url: 'https://example.com',
options: {
printBackground: true,
format: 'A4',
},
}),
}
);

const buffer = await response.arrayBuffer();
fs.writeFileSync('output.pdf', Buffer.from(buffer));

PDFBolt

const fs = require('fs');

async function generatePdf() {
const response = await fetch('https://api.pdfbolt.com/v1/direct', {
method: 'POST',
headers: {
'API-KEY': 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
'Content-Type': 'application/json'
},
body: JSON.stringify({
url: 'https://example.com',
format: 'A4',
printBackground: true
})
});

if (!response.ok) {
const errorText = await response.text();
throw new Error(`HTTP ${response.status} - ${errorText}`);
}

const pdfBuffer = await response.arrayBuffer();
fs.writeFileSync('webpage.pdf', Buffer.from(pdfBuffer));
}

generatePdf().catch(console.error);

"There's a lot of products that convert to PDF out there, but this one stood out to me, because the output quality is good, it's very easy to use, and pay per use. I also love the interactive API documentation, my request just worked out of the box in my app. And of course the focus on privacy, which is important when working with GDPR data. (...) PDFBolt just works, so I can focus on the business logic."

Frequently Asked Questions

Straight answers about Browserless PDF generation, pricing, self-hosting, and when PDFBolt fits.

Both platforms offer Chromium-based HTML to PDF APIs for converting URLs or HTML through REST. PDFBolt adds managed Handlebars templates, a visual Template Designer, AI-assisted template creation, Direct, Sync, and Async workflows, signed webhooks, S3-compatible delivery, compression, and PDF/X/CMYK output. Browserless remains better suited to scraping, screenshots, proxies, CAPTCHA handling, and browser sessions.
Yes. Browserless accepts a URL or raw HTML and supports Chromium print options, waits, authentication, cookies, and request headers. It makes particular sense when PDF is one step in a scraping or browser-automation workflow. PDFBolt is a better fit when the workflow depends on reusable templates, background delivery, compression, or print-ready output.
No. Call Browserless's POST /pdf REST endpoint directly to receive a binary PDF. Puppeteer, Playwright, BrowserQL, and custom Puppeteer functions are options for more involved browser workflows.
They count different things. Browserless meters browser time in rounded 30-second units and adds units for proxy traffic or CAPTCHA solving. PDFBolt pricing uses monthly document quotas and counts only successful conversions. Compare real render times, file sizes, and Browserless add-ons rather than treating the quotas as equivalent.
Yes. Browserless documents Docker-based self-hosting alongside its managed service. Review its SSPL and commercial license terms for your deployment. PDFBolt is managed SaaS and does not offer self-hosting.
Usually, when the request converts a URL or HTML with standard print settings. Move print options out of Browserless's nested options object. Then move authentication from Browserless's token query parameter to PDFBolt's API-KEY header and Base64-encode raw HTML for PDFBolt REST requests. A workflow that relies on clicks, logins, proxies, stealth, CAPTCHA handling, request interception, or earlier BrowserQL actions is not a direct migration.
No. PDFBolt generates PDFs. It does not provide scraping, screenshots, browser sessions, remote Puppeteer or Playwright connections, proxies, stealth tooling, or CAPTCHA handling. Keep Browserless when the workflow needs those capabilities.
