About Substack
Learn what Substack offers and what valuable data can be extracted from it.
Independent Publishing Hub
Substack is a prominent American platform that provides the infrastructure for writers to publish, monetize, and manage subscription newsletters. It has become a central hub for independent journalism, expert analysis, and niche content, allowing creators to bypass traditional media gatekeepers and build direct relationships with their audience through email and the web.

Code Examples
import requests
from bs4 import BeautifulSoup
import json
url = 'https://example.substack.com/archive'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/119.0.0.0'}
try:
response = requests.get(url, headers=headers)
response.raise_for_status()
soup = BeautifulSoup(response.text, 'html.parser')
posts = soup.find_all('div', class_='post-preview')
for post in posts:
title = post.find('a', class_='post-preview-title').text.strip()
print(f'Post Found: {title}')
except Exception as e:
print(f'Error: {e}')When to Use
Best for static HTML pages where content is loaded server-side. The fastest and simplest approach when JavaScript rendering isn't required.
Advantages
- ●Fastest execution (no browser overhead)
- ●Lowest resource consumption
- ●Easy to parallelize with asyncio
- ●Great for APIs and static pages
Limitations
- ●Cannot execute JavaScript
- ●Fails on SPAs and dynamic content
- ●May struggle with complex anti-bot systems

Pro Tips for Scraping Substack
Expert advice for successfully extracting data from Substack.
Look for 'window._substackData' in the HTML source code to extract structured JSON data without complex parsing.
Implement random sleep intervals of 10-15 seconds between archive page requests to avoid 'Too Many Requests' errors.
Use residential proxies to bypass Cloudflare and IP-based rate limiting when scraping at scale.
Target the '/api/v1/archive' endpoint directly if you can reverse-engineer the query parameters for faster extraction.
Prioritize scraping during off-peak hours (relative to US eastern time) for potentially more stable response times.
Always set a realistic User-Agent that matches a modern desktop browser to avoid immediate detection.
