Sharing Demos in a Slack or Discord Community
August 28, 2026
Communities are full of exactly the people you want and are unusually hostile to being sold to, for good reason — most attempts are lazy and everybody has seen a hundred.
The distinction that matters is not whether you mention your product. It is whether the message is worth reading for somebody who never buys anything.
Answer the question that was asked
The one context where linking your product is welcome is a thread where somebody described a problem it solves. Even then, answer the question properly first and mention the product as a footnote.
A reply that solves the problem generically and then says "we built something for this, here it is if useful" is read as helpful. The same link with no answer around it is read as spam, and correctly.
Show, do not describe
A demo link is less promotional than a paragraph of claims, because the reader can check it in twenty seconds and decide for themselves.
It also survives scrutiny in a way marketing copy does not. In a room full of people who build software, "here it is, look" is a stronger position than any description you could write.
Your own community is different
- Feature launches, where a walkthrough beats a paragraph.
- Support answers, which then serve everyone who searches the channel later.
- Onboarding new members, who all ask the same first questions.
- Showing what somebody built with it, which is the most persuasive thing you can post.
The rule that keeps you welcome
Contribute in threads that have nothing to do with your product far more often than you mention it. That is not a tactic; it is the actual price of being in a community.
People who do this get away with the occasional link because they are visibly a member. People who do not get muted, and deserve to be.
Frequently asked questions
- Can I share my product in a Slack or Discord community?
- In a thread where somebody described a problem it solves, and only after answering the question properly. A reply that solves the problem generically and then mentions your product as a footnote reads as helpful; the same link with no answer around it reads as spam.
- Is a demo link less promotional than a description?
- Generally yes, because the reader can check it in twenty seconds and decide for themselves rather than taking a claim on trust. In a room full of people who build software, "here it is, look" survives scrutiny better than any copy you could write.
- How do I use demos in my own community?
- For feature launches, support answers that then serve everyone who searches later, onboarding new members who all ask the same first questions, and showing what somebody else built with your product -- which is the most persuasive thing you can post.
