Harken vs Social Searcher

Harken tracks mentions of keywords, brands, or products across online sources and brings sentiment and themes into a local dashboard. It can monitor Hacker News, Reddit, Mastodon, Bluesky, Stack Overflow, RSS, X, and YouTube. Sentiment comes from a built-in local lexicon analyzer; optional LLM analysis can label themes using Anthropic, OpenAI, or locally run Ollama. Harken provides a web dashboard and terminal CLI, stores its database in local SQLite, and says it sends no Harken telemetry. Alerts for new negative mentions or configured volume and sentiment thresholds can go to Slack, generic webhooks, or SMTP email. The open-source MIT software is self-hosted and free: free, with no per-seat pricing and API access. Tracking sends search terms to selected source APIs, and Anthropic or OpenAI theme labeling sends a small sample of mention text to that provider. Hacker News and Bluesky work without credentials; other sources may need credentials, configured feeds, or tokens. The quickstart requires Python 3.10 or later, and Docker Compose instructions are included.

Social Searcher is a web tool for searching publicly available social content and monitoring mentions. It covers Facebook, Twitter, Instagram, LinkedIn, YouTube, Tumblr, Reddit, Flickr, Dailymotion, and VKontakte, and can return profiles, posts, mentions, images, and conversations. Results can be filtered and sorted or ordered by relevance and date. Search options include exact phrases, excluded terms, and OR; users can also search images and hashtags. Users Search finds public profiles by name or username, while Trending Hashtags follows viral tags across platforms. Social Listening monitors brand mentions and awareness; the service also lists web and news monitoring, sentiment analysis, and email or RSS alerts. It says it uses publicly indexed data from major search engines. The free plan is listed at free, with 100 real-time searches per day, one monitoring, and 500 saved posts per month. The service also describes searches as uncapped and available without registration, while plan details specify daily limits. Social Searcher is made by a Berlin-based company founded in 2011.
