What Show HN is and who reads it
Show HN is the section of Hacker News where you post something you made. A successful Hacker News Show HN launch can send thousands of technical, skeptical, high intent visitors to your product in a day.
The audience matters. Hacker News readers are mostly engineers, founders, and technically literate early adopters. They are curious and generous, and they have a very low tolerance for marketing.
This shapes everything about how you launch. What works on Product Hunt or X often fails here, because the crowd is different.
If your product is a developer tool, an open source project, or anything technically interesting, Show HN is one of the best channels you have. If it is a consumer lifestyle app, it may not be your crowd.
How to write the Show HN post
The title is most of the battle. Hacker News titles are plain and factual, and anything that smells like marketing gets ignored or flagged.
Use the format "Show HN: [what it is] [what it does]." For example, "Show HN: A tool that finds where your SaaS users hang out online." No adjectives, no hype, no exclamation marks.
Then write a short first comment that explains:
- Why you built it, in one or two honest sentences
- What it does and how it works technically
- What is genuinely hard or interesting about it
- What you are still figuring out or would like feedback on
That last point matters more than founders expect. Hacker News responds to people asking for real feedback, not people announcing a finished product.
Have a working demo or a clear way to try it without signing up. Readers will not give you an email before they have seen the thing work. A login wall on a Show HN is a near guaranteed failure.
The two hour engagement window
Timing on Hacker News is unforgiving. After you post, you have roughly two hours where activity decides your fate.
If your post gets upvotes and comments quickly, the ranking algorithm pushes it toward the front page, where most of the traffic lives. If it stalls, it sinks and rarely recovers.
This means you must be present and fully available for those two hours. Do not post and walk away. Sit with it and respond to every comment as fast as you reasonably can.
Posting time affects this. Weekday mornings in US time zones tend to have the most active readership, though there is no perfect slot. Pick a time when you can genuinely be present, because your responsiveness matters more than the exact hour.
Do not ask friends to upvote. Hacker News detects voting rings and will penalize or bury your post. Organic early engagement is the only kind that helps.
How to handle the comments
The comments are where a Show HN is won or lost. The audience is sharp and often blunt.
Answer every technical question directly and honestly. If someone finds a flaw, acknowledge it plainly rather than defending. "You are right, that is a real limitation, here is how I am thinking about it" earns respect.
Expect criticism and do not take it as hostility. Hacker News critique is usually a sign of engagement, and a thoughtful reply to a tough comment often wins over the people reading silently.
Never argue defensively or use marketing language in replies. The fastest way to lose the room is to sound like a brochure when someone asks a real question.
If someone compares you to an existing tool, respond with substance about the actual differences, and never disparage the competitor. The community values fairness and will side against you if you do not.
What Show HN is and is not good for
Set your expectations correctly so you can read the result honestly.
Show HN is excellent for credibility, technical feedback, and a concentrated burst of high quality early users. The people who sign up tend to be sophisticated and will give you sharp, useful input.
It is not a sustained acquisition channel. The traffic spikes on launch day and then fades, like most launch moments. You cannot relaunch repeatedly.
It also skews technical. If your real customer is non technical, the Show HN crowd may praise your engineering while not being your buyer. That is fine, as long as you know it going in.
Treat Show HN as one strong moment inside a longer distribution effort, not as the whole plan. The community presence you build elsewhere is what compounds over months. Show HN is a spike, and spikes are useful but temporary.

Frequently Asked Questions
What makes a Show HN post reach the front page? Fast organic upvotes and genuine comment activity in the first couple of hours are what push a Show HN toward the front page. A plain factual title, a working demo with no signup wall, and an active founder answering every comment all increase the odds.
What time should I post a Show HN? Weekday mornings in US time zones tend to have the most active Hacker News readership, but the most important factor is posting when you can be fully present for the following two hours. Your responsiveness to early comments matters more than hitting a perfect time slot.
Can I ask friends to upvote my Show HN? No, you should never ask for coordinated upvotes, because Hacker News detects voting rings and will penalize or bury your post. Only organic early engagement helps your ranking, so focus on a strong title and demo instead.
Is Show HN worth it for a non technical product? Show HN works best for developer tools, open source projects, and technically interesting products, because the audience is mostly engineers. A non technical consumer product can still get feedback there, but the crowd may praise the build without being your actual buyer.
