What It Is

Mentions.us is a keyword mention monitoring SaaS with a very clear focus: when your brand, product, project, or keyword is discussed on platforms such as Reddit, Bluesky, Mastodon, Hacker News, and Stack Overflow, it notifies you via Slack or email. It is geared more toward developer communities and technical sentiment monitoring than traditional full-spectrum social media marketing.

Core Features

Its coverage includes posts and comments across Reddit, Bluesky, Mastodon content federated with flagship instances, Hacker News, Stack Overflow questions, answers, and comments, DEV Community, Lobsters, Product Hunt, public Slack communities, and some public forums. On the search side, it supports querying mentions from the past week, case sensitivity, in-word matching, additional include/exclude terms, and subreddit restrictions. On the notification side, it emphasizes near-real-time alerts “within minutes,” delivered to Slack or email. For Slack integration, it highlights that it requires almost no read permissions, does not read customers’ private Slack conversations, only stores channel references and postable URLs, and encrypts sensitive data at rest.

Pricing and Value

Pricing is straightforward: personal email alerts are free for up to 100 keywords; the free Slack plan supports up to 5 keywords; Basic costs $25/month for 25 keywords; Pro costs $50/month for 100 keywords. All tiers list near-real-time alerts and full platform coverage, and the free tier does not require a credit card. For early-stage products, open-source projects, or indie developers, the free email plan offers strong value. Teams that need Slack-based workflows will need to upgrade based on keyword volume.

Pros and Cons

Its strengths are that it is easy to get started with, focuses on platforms that matter in the developer ecosystem, has simple pricing, and offers a generous free tier. It is well suited for monitoring user feedback, competitor comparisons, and brand exposure on Hacker News, Reddit, and Stack Overflow. The limitations are also clear: the main copy does not mention a public API, SDK, Webhook, or self-hosting option; the terms of service also state that consulting, training, troubleshooting, and support services are not included. In terms of documentation, the homepage and terms provide sufficient basic information, but there is a lack of deeper integration documentation or operational guidance.

Who It’s For and Access from China

Mentions.us is suitable for developer tool companies, SaaS startups, open-source maintainers, community operators, and marketers who need to discover discussions and feedback in a timely manner. The main copy does not state how well it works from mainland China. Since monitored sources such as Reddit, Hacker News, Stack Overflow, and Slack can be unstable to access from China, actual use may require a reliable network environment. Payment methods are not disclosed. If international credit cards are not available, alternatives such as Google Alerts, F5Bot, Brand24, or Mention may be worth considering.
