Harken vs Mentionlytics

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.

Mentionlytics is a social listening and brand-monitoring platform for tracking online discussion about brands, products and competitors. It monitors websites, news, blogs, forums, reviews and social networks, including X, TikTok, LinkedIn, Facebook, Instagram, YouTube, Reddit, Bluesky and Threads. Its dashboard includes brand-awareness, sentiment, reach, engagement and share-of-voice measures; it also tracks more than 100 review sources. AI capabilities cover sentiment and emotion analysis, anomaly detection, mention clustering, translation, image recognition, and video and audio analysis. Teams can create and share custom reports, use tags and maintain separate client or brand accounts on supported plans. Alerts can be sent by email or Slack. The service offers web and API access, and integrations include Hootsuite, Looker Studio, Power BI compatibility and MCP. The 14-day trial does not automatically charge users when it ends, and subscriptions can be canceled at any time. Paid plans are billed yearly and start at $69 per month. Mentionlytics was founded in 2016 in Ierapetra, Crete, Greece.
