How to make a Reddit post mockup
No account, no sign-up, completely free. The card renders live and the PNG is created in your browser, so nothing you type is ever uploaded.
Write the post
Set the subreddit, username, and how long ago it was posted, then write the title and optional body text. Add a flair tag if you want one.
Build the thread
Add comments, set each one to top level or a nested reply, give it a username, an age, and a score, and tag the author with OP.
Style and export
Pick light or dark, set the upvote count, toggle the Join button and award row, then download a crisp 2x PNG.
The Details
What makes a thread mockup look real
Forum screenshots live or die on proportion. The numbers, the nesting, and the voices all have to belong to the same post.
score : comments : age = the three numbers that must agree
A post with 4.2k upvotes and four comments is not a thread anyone recognizes. Scale the comment count to the score, keep the post age older than the newest reply, and let at least one comment be a nested answer from the author.
Then vary the voices. A useful thread has someone agreeing, someone asking a practical question, and someone pushing back a little. Uniform praise is what a marketing team writes, not what a community produces.
The purpose stays the same throughout. This is a design asset for comps, teaching, and jokes. Invent every community and username, caption it as a mockup where it matters, and never present it as a real discussion.
Settings
Every control, and when to use it
Six settings shape the export. Here is what each one changes and the job it fits.
| Setting | What it does | Best for |
|---|---|---|
| Subreddit and username | The r/ community and u/ author shown above the title | Setting the context of the post. Keep both invented Most used |
| Flair | A small tag beside the title, such as Discussion or Help | Signalling what kind of post it is at a glance. Leave blank to hide it Situational |
| Upvotes | The score in the vote pill, shortened to 4.2k style above a thousand | Matching the size of the reaction to the size of the community Most used |
| Comment depth | Top level, Reply 1, or Reply 2, drawn with an indent and a thread line | Showing a real back and forth instead of a flat list of replies Most used |
| OP tag | Marks a comment as written by the original poster | Threads where the author answers a question in the comments Situational |
| Dark theme | Near-black card with light text, the common dark forum palette | Reels, dark slides, and thumbnails that need contrast Situational |
Layout follows the common light and dark forum card patterns as of 2026. This tool is not affiliated with, or endorsed by, Reddit.
Use It Right
Good uses, and the two to never touch
A post mockup is a graphic. These are the jobs it is built for, and the two uses that turn it into something else.
| Scenario | What it is | Verdict |
|---|---|---|
| Content and community comps | Showing what a thread would look like before a community exists | Good use |
| Presentations and case studies | Illustrating a discussion pattern or a customer objection with invented users | Good use |
| Memes and fiction | Clearly humorous threads written for a joke, a comic, or a video script | Good use |
| Teaching and workshops | Explaining how forum voting, threading, and flair work | Good use |
| Fake screenshots of real threads | Editing what a real person or community appears to have said | Never |
| Manufactured social proof | Presenting invented praise as genuine, unpaid community endorsement | Never |
Avoid These
What gives a mockup away, and the line never to cross
Four of these are craft. The first two are not negotiable. Read them before you export anything that leaves your own screen.
Passing a mockup off as a real thread
This outweighs everything else here. A generated image is not a record of a discussion. Presenting one as a genuine thread to sell something, win an argument, or damage someone is deception.
Never present it as realUsing a real community or account
A real subreddit name plus a real username reads as a screenshot of that community. Invent both. Communities have rules about impersonation, and so does the law in many places.
Invent both namesVote counts that do not add up
A post with tens of thousands of upvotes and four comments looks wrong to anyone who uses forums. Keep the score, the comment count, and the age of the post in proportion.
Keep scores in proportionA flat comment thread
Real threads nest. If every comment sits at the top level, the mockup reads as a list. Use Reply 1 and Reply 2 so at least one exchange has a genuine back and forth.
Nest at least one replyComments that all sound the same
One skeptic, one enthusiast, one person asking a practical question. Uniform agreement in every comment is the clearest sign a thread was written by one person.
Vary the voicesAwards on a tiny post
Awards signal that a lot of people saw something. Two awards on a post with 30 upvotes reads as decoration, so switch the row off when the score is modest.
Awards need scaleBest Practices
8 tips for a thread mockup that lands
All CommonNinja widgets mentioned below are free to start. Use these while you write the thread and after you place the export.
01
Write the title like a person, not a marketer
Forum titles are specific and a little plain. A concrete detail beats a clever hook, because that is how posts actually get written.
02
Invent the subreddit and the username
A made-up community and author keeps the mockup a design asset. It also keeps you clear of impersonating a real community.
03
Right-size the score for the story
A few hundred upvotes reads as a solid post in a niche community. Tens of thousands implies a front-page moment, so only use it if the rest of the mockup supports that.
04
Nest the replies
Set one comment to Reply 1 under its parent, and answer it with an OP-tagged reply. That single exchange does more for realism than any other setting.
05
Give the comments different jobs
Agreement, a question, a mild disagreement, then the author answering. Four distinct intentions read as a real thread.
06
Put real discussion on your own pages
A mockup shows what engagement looks like. A comments widget lets it actually happen on your site instead of somewhere else.

Bring real threads onto your site
If the discussion about your product already happens on Reddit, a feed widget can surface it on your own pages, where it does you some good.

Say it is a mockup
One caption noting the thread is a design mockup removes all ambiguity, and costs nothing in a deck or an article.
