Substack Scraper

Export any Substack newsletter's archive — on *.substack.com or a custom domain — as clean JSON / CSV / Excel. No login, no browser, no proxies: the Actor reads Substack's public archive feed, so counts are exact and runs finish in seconds.

Per post: title, subtitle, description, URL, date, type (newsletter / podcast / video / thread), authors with Substack handles, per-emoji reactions and total likes, restacks, comment and reply counts, word count, paywall status, tags, section, cover image, podcast URL and duration, video / voiceover flags, pinned flag, restack source, public preview text, and optionally the full body as HTML and plain text.

Per publication: name, author, description, subscriber count (exact when Substack displays a number, otherwise the tier such as "hundreds of thousands of subscribers"), custom domain, paid and podcast flags, podcast feed URL, language, logo, cover photo, creation date.

Example post

Input

Field	Default	Notes
publications	—	lenny, noahpinion.substack.com, https://www.platformer.news — one per line
maxPostsPerPublication	50	newest first; 0 = whole archive
lastNDays / sinceDate / untilDate	—	date window; use sinceDate on a schedule to fetch only new posts
sort	new	top returns Substack's most-liked order
postTypes	all	newsletter, podcast, video, thread
audience	all	free or paid posts only
includeBody	off	adds bodyHtml + bodyText; paywalled posts return the public preview with bodyTruncated: true
includePublicationInfo	on	one publication item per newsletter

Uses

• Newsletter research / competitor tracking — likes, restacks and comments per post, sorted by top.
• Content archives — maxPostsPerPublication: 0 + includeBody for a full-text corpus (free posts in full, paid posts as previews).
• Monitoring — schedule daily with lastNDays: 2; only new posts are billed.
• Discovery lists — feed hundreds of subdomains, keep the publication items for author, description and subscriber tier.

Honest limits

• Paywalled bodies are only the public preview — Substack does not expose paid text without a subscription, and this Actor never logs in.
• Substack shows exact subscriber numbers only for some publications; others get the tier text, returned verbatim in subscribersText.
• Bare names map to <name>.substack.com. A few big newsletters have an unrelated subdomain squatter, so paste the full URL for custom-domain publications.
• Notes (Substack's short-form feed) and comment threads are not included in this version.

Pricing

Pay per result: one post or one publication record = one result. The free trial covers a first run.
