Bluesky & Lemmy Brand Monitor

Monitor brand, competitor, and keyword mentions on Bluesky and Lemmy. This Actor uses public APIs for open social networks and returns one structured dataset row per matching public post.

Use it for brand monitoring, launch tracking, competitor mentions, developer relations, community research, support escalations, and lightweight social listening without relying on X/Twitter credentials.

What does this Bluesky and Lemmy monitor do?

Open Social Brand Monitor searches public Bluesky posts through the AT Protocol API and public Lemmy instances through the Lemmy API. It normalizes results into one Apify dataset with post text, author handle, source URL, created date, matched query, and engagement score.

It requires no login, no browser, and no private credentials.

The Actor also writes key-value outputs for scheduled workflows:

• RUN_SUMMARY: counts, inputs, deduping, and errors
• POST_EXPORT: all emitted social post matches
• BUYER_BRIEF: a short Markdown brief by platform, query, and engagement
• SLACK_ALERTS: compact alert objects for webhook or chat workflows

Pricing

This Actor uses pay-per-event pricing. Dry-run examples are not charged. Apify free-plan users get the first 25 social post match records without this Actor's custom event charge; after that, normal pay-per-event pricing and the user's run spending limit apply.

Event	Price	What counts
social-post-match	$0.001	One matched public Bluesky or Lemmy post written to the dataset

That is $1 per 1,000 emitted social post matches, plus normal Apify platform usage. It is designed for daily monitoring across several saved searches.

Common use cases

• Track brand and product mentions after a launch.
• Watch competitor comparisons on open social networks.
• Find developer questions and complaints in your category.
• Monitor support issues that mention your product.
• Build a daily social-listening feed for Slack, email, Sheets, or Airtable.

Limits and compliance

The Actor only uses public API data. It does not log in, bypass access controls, scrape private posts, enrich contacts, harvest followers, or archive deleted content.

Use the output for monitoring and research, not spam, harassment, sensitive profiling, or context-free claims about individual users.
