Mastodon Scraper 🐘 — Hashtags & Public Timeline (No Login)

Scrape public Mastodon posts across the fediverse — by hashtag on any instance, plus the public timeline where allowed. Clean, HTML-stripped text with engagement and author data. No login required. Export to JSON/CSV/Excel.

For social listening, lead generation, and researchers tracking the migration off X/Twitter.

What makes it better

• Works everywhere — hashtag timelines work even on instances (like mastodon.social) that now require login for the public timeline. Most scrapers break there; this one doesn't.
• Any instance — point it at mastodon.social, mastodon.world, fosstodon.org, or your own.
• Clean output — HTML stripped to plain text, with favourites/boosts/replies and author follower counts.

Example input

{
"instance":"mastodon.social",
"hashtags":["ai","opensource"],
"includePublicTimeline":false,
"maxItems":200
}

Example output

{
"url":"https://mastodon.social/@user/123",
"text":"Just shipped a new open-source AI tool!",
"authorAcct":"user",
"authorFollowers":1840,
"favourites":23,
"reblogs":7,
"tags":["ai","opensource"]
}

Use cases

• Track a hashtag for brand/topic monitoring.
• Build lead lists of people posting about your niche.
• Research fediverse trends and sentiment.

Tip

For the public/federated timeline, use a permissive instance like mastodon.world — mastodon.social requires login for it (but hashtags work fine there).

Run locally

pip install-r requirements.txt
