Fake Slack Message Generatorfor product and team stories
Slack screenshots explain how work happens: a launch going live in #announcements, a bug triaged in minutes, a team celebrating a win. MockupChat recreates the Slack mobile screen — aubergine header, square avatars, reaction counts — so you can show those moments in a pitch deck, a case study layout or a recruiting post without exposing your real workspace.
Slack is a Pro platform: edit and preview for free, export with Pro for $9.99/month. Updated .

Every skin: iPhone & Android · Light & dark mode · Status bar time, battery & signal · Photos & big emoji · Your own avatars.
Channels with the # header
With three or more people and a header title, the top bar reads #your-channel in bold white on Slack's aubergine. Two people make a direct message with the person's name instead.
Square avatars with initials
Slack uses rounded squares, not circles. Without a photo, each person gets an initial on one of Slack's flat default colours — pink, green, yellow, blue or purple.
Reactions with counts
Emoji reactions sit in small pills under the message with a count, outlined in blue when you've reacted too. Great for showing a 🎉 pile-on after a launch.
Dark mode and replies
Dark mode switches to Slack's charcoal theme. Replies quote the original message above the answer, which keeps a busy channel readable.

What people make with Slack mockups
Pitch decks and storyboards
Storyboard how your team works or how a launch day could unfold, with an illustrative channel instead of a grey placeholder.
Integration and bot demos
If your product posts into Slack, preview exactly how its messages will look in a channel before you build the app.
Culture and recruiting posts
Give candidates a feel for how your team talks with an illustrative #wins or #random conversation.
FAQ
Slack generator questions
Yes. Add three or more people and set a header title. The header then shows #title, just like a Slack channel on mobile.
Yes. Upload a photo per person or keep the coloured initial squares Slack uses when someone has no picture.
You can build Slack mockups for free. Exporting them is part of Pro at $9.99 per month, including frames and social formats.
Yes. Dark mode uses Slack's dark charcoal for both the header and the message list, with light grey text.
No, because Slack channels don't show read receipts and the skin leaves out audio clips. Text, images, link previews, reactions and replies are all supported.
Yes, as a clearly illustrative visual. Don't present it as a real customer's workspace or put words in a real company's or person's mouth — our Terms forbid both.
Use it responsibly
MockupChat makes mockups for content, ads, memes, storytelling, app demos and presentations. Don't pass a mockup off as a real conversation, put words in the mouth of a real person or customer, or use it to mislead anyone. Where a screenshot could be taken for real, label it as an illustration. The details are in our Terms.
