Which Slack communities do you support?

Currently we monitor these communities:


Is yours missing? No problem, just let us know and we'll add it.

That's in addition to all these places of course:

Lobsters Stack Overflow Product Hunt Indie Hackers Reddit Twitter Hacker News Slack Growth Hackers Server Fault Facebook Upwork Spiceworks Stack Exchange etc

You can use Syften to receive alerts whenever a thread is started or a reply is posted with the keywords you want to monitor. This allows you to be one of the first to comment or find new discussions that are relevant to you or your business.

You can also monitor the activities of other users and see their comments. That's useful if you want to do influencer marketing, help your team stay in sync with eachother's actions or learn what your competitor is doing.

And if someone posts a link to your article you can be the first to give it a bump.

Check out what our customers have to say

Syften has enabled us to keep an eye on the topics related to our product. We can easily track posts about discount codes, email marketing, and e-commerce. We can then suggest using our service, or just be helpful answering questions on subjects that we are familiar with.

Syften constantly discovers actionable conversations related to our product. This allows us to engage with useful and timely replies, as well as focus on features that actually solve real user problems.

Syften has been a great tool to understand in which communities my website is being mentioned, or topics relevant to my business. It allowed me to engage in meaningful discussions and to identify some important actors in my niche.

I've written a couple books and like to keep an eye on how and where folks are talking about them. Syften has helped me catch several key conversations that I otherwise wouldn't have seen. Even on the days without any notable alerts, I'm still happy to know that I haven't missed anything. A very useful tool.

Limit search to Slack communities only

Syften can search Reddit, Twitter, and many other leading communities. To limit a filter to Slack only specify

Limit search to just this one Slack community

You can narrow down your search to individual communities:

Channel tracking

We put the channel name in what is normally the post title for other backends:

And of course, the channel ID is also included in the URL:

Track users

Unfortunately we can't easily tell what the "Username" (e.g. reginald) of a Slack user is and the "Display Name" (e.g. Reginald Terris) is optional and can easily be changed.

So to make identifying users reliable we put the User ID (e.g. U57JWU42T) in the title field. Additionally, to make it convenient to view, we put the "Username" in the author field.

Track replies to your messages

To track replies to your threads track your own Slack user. Keep in mind that the User ID will, and the Username may be different in every Slack community.

Learn from the best

See how the best do their marketing and learn from them. To avoid tracking their username across the different communities you can just follow urls to their websites.

You can see more examples in the documentation.

Implementation Details

  • Alerts are available with an up to 1 minute delay
  • Since Slack messages have no title, we're constructing a faux one that looks like this:
    message from someuser (U012ABCDEFG) in
  • Item edits are tracked
  • Thread replies are tracked
  • The replyto: operator is not supported


  • It's inconvenient to track a user across multiple Slack communities, as their username may be different.
