Substack Scraper — Newsletter Posts, Likes & Full Text

Scrape the posts of any Substack newsletter, on substack.com or on its own custom domain: title, subtitle, date, authors, likes, comments and restacks, word count, whether it's paid or free, and the full text of free posts (public preview for paid ones).

Use it to research what performs in a niche, track competitors' newsletters, build reading datasets or feed newsletter content to AI tools.

Why this one

• Custom domains work (lennysnewsletter.com), not only *.substack.com.
• Engagement numbers for every post: likes (reactions), comments, restacks.
• Clean text of free posts, ready for analysis; optional raw HTML.
• Paid vs free flag and post type (newsletter, podcast, thread).
• Date filter and many publications in one run.
• Pay per post delivered. Publications that aren't on Substack are reported, free.

How much does it cost?

You pay only for results delivered, at a fixed price per item. Apify platform usage is included in that price, so there are no compute costs on top. Errors and items that couldn't be found are free.

What you get	Price	Example
Post delivered	$0.003 each	1,000 post delivereds = $3.00

The Apify Free plan includes $5 of monthly credit, enough for about 1,666 post delivereds per month at no cost. You can also set a maximum spend per run.

On paid Apify plans it gets cheaper automatically: 10% off on Starter, 20% on Scale and 30% on Business.
