Lemmy Scraper: Posts, Comments, Communities & Users

Scrape Lemmy, the federated Reddit alternative, through its official API: posts from any community on any instance, keyword search, full comment threads and user histories, plus community statistics.

No login, no API key and no browser: the Actor reads the data directly, which makes it fast and cheap. Proxies are included in the price.

What can you use it for?

• Social listening: track mentions of your brand or topic across the fediverse.
• Community research: compare activity, subscribers and top posts.
• Content curation: collect the best links of a niche.
• AI & NLP datasets: gather discussions and comments.

Inputs that cannot be scraped (wrong URL, not found, blocked) get a free row with status and error, so you always know what happened. A run summary is saved to the key-value store as SUMMARY.

Pricing

You pay per item saved. Proxies and compute are included. Set a maximum cost per run and the Actor stops cleanly when it is reached.

FAQ

Which instances work? Any Lemmy server: lemmy.world, lemmy.ml, sh.itjust.works, programming.dev, beehaw.org and others. Write the community as name@instance.

Do I need an account? No.

Why are proxies off by default? The Lemmy API is open, so runs are faster and cheaper without them.

Can I call it from code or an AI agent? Yes, via the Apify API, the official JS/Python clients, or Apify's MCP server.
