How to launch on Hacker News means a Show HN for something people can try, not a press release on news.ycombinator.com. The room is allergic to marketing language. It rewards a working demo, a plain title, and a maker comment that sounds like an engineer who shipped - because that is the room.
This is the 2026 Show HN playbook. It is not a Product Hunt clone. PH timing lives on best day to launch on Product Hunt. The rest of the week still needs a lasting URL: where to launch a startup.
TL;DR
- How to launch on Hacker News: post
Show HN: <thing>only when a stranger can try it without a sales call. - How to post on Hacker News as a launch: Tuesday-Thursday morning (roughly 8-11am ET), aged account, immediate maker comment, no upvote asks.
- Show HN is for things you built. Ask HN is for questions. Do not mix them.
- HN links are usually nofollow UGC. Take the thread for users and quotes. Take ScrollLaunch the same week for a dofollow product page.
- If the product is a waitlist or a pitch deck, do not Show HN. You will get flagged, not featured.
What Show HN Is (And Is Not)
Show HN is a gentlemen’s agreement: you made a thing, the link goes to the thing, people can try it.
| You have | Show HN? | Do this instead |
|---|---|---|
| Live demo, no hard paywall | Yes | Post the demo URL |
| OSS repo people can run | Yes | Link the repo or a working deploy |
| Waitlist / “book a demo” | No | BetaList + owned email |
| Pure landing page, no product | No | Finish the product |
| Recycled launch blast | No | You will get flagged |
Key point: How to do a Show HN is “here is the work.” It is not “here is the positioning.” If the first paragraph needs the word synergy, rewrite it or do not post.
Dev-tool adjacent boards if you want a calmer room the same month: DevHunt. Consumer spike still belongs on Product Hunt. Archive row for HN: Hacker News directory.
How to Post on Hacker News Without Getting Flagged
1. Use an account that looks like a person
Do not create the account on launch morning. Comment on other threads for a couple of weeks. Read HN guidelines. Vote-ringing, asking friends to upvote, and “please HN” Slack blasts are how threads die.
2. Title like a human
Pattern that works:
Show HN: <name> - <one concrete thing it does>
Examples of tone, not copy-paste:
Show HN: A CLI that diffs two production sitemapsShow HN: I made a weekly launch board with dofollow product pages
Avoid: revolutionary, AI-powered platform, all-in-one, “the X for Y” unless Y is painfully specific.
3. Link the work, not the blog post about the work
If they cannot try it in 30 seconds, you are asking them to trust a story. HN does not.
4. Write the maker comment before you submit
Post it immediately. Structure:
- What it does in one sentence
- Why you built it (the itch, not the TAM)
- How it works, briefly
- What is still rough
- One specific question you want feedback on
Mention price only if asked, and mention it plainly. The HN Show page is full of threads that died because the first comment was a feature list.
5. Pick a weekday morning, then stay
There is no official reset like Product Hunt’s 12:01 AM PT. Practitioners still see better odds Tuesday-Thursday, roughly 8-11am Eastern, when US and EU overlap. If the first hour is silent, do not repost the same week. Sit in the thread you have.
6. Reply like an engineer
Answer criticism. Do not argue tone. If someone finds a bug, fix it or say when you will. Defensiveness is a downvote magnet.
How to Launch on Hacker News as Part of a Week
HN is a community spike. It is a weak only channel.
Same week, different hours:
- Show HN when you can babysit comments for 4-6 hours.
- ScrollLaunch for
/products/[slug]and the weekly board. Dofollow rules: pricing. - 10-15 Free + Dofollow directories after the thread cools - archive.
Do not cross-post the same paragraph to PH, HN, and five Discords in one minute. That is how both rooms clock you as a blast.
If you also want the PH day, do not make it the same morning. Sequence: how to promote a SaaS.
What You Should Expect
| Outcome | Typical | What to do |
|---|---|---|
| Front page | Uncommon | Reply for 12 hours. Fix the landing page from comments. |
| A few dozen thoughtful comments | Common if the thing is real | That is a win. Quote them. |
| Flagged / dead | Common if it looks like marketing | Do not repost. Read the guidelines again. |
| Signup spike, then silence | Normal | You needed the lasting URL anyway |
The outbound link from an HN thread is usually nofollow. Use it for users. Use directories and ScrollLaunch for the backlink graph. Check a target’s DR with the Ahrefs DR checker if you start chasing listing SEO after the thread.
If your own site cannot survive a traffic spike, that is a product bug. SEO It Is will not fix a 2s TTFB, but it will tell you if crawlers can even see the page HN just sent people to. A thin marketing site is faster to replace with SuperFast than to debug under load.
Show HN Mistakes That Kill Threads
- Signup wall before any value
- “Launching on HN, PH, and Twitter today!”
- Asking for upvotes in Slack / Discord
- Linking a Notion doc
- Reposting the same Show HN every Friday
- A title that is an ad
- Ignoring the first ten comments
Public accountability while you wait for a better week: MakeItLast. HN can smell a founder who only appears on launch day.
Key Takeaways
- How to launch on Hacker News = Show HN + tryable product + maker comment + weekday morning + no vote begging.
- How to post on Hacker News as marketing will get you flagged. Post as a builder.
- Take the thread for feedback. Take ScrollLaunch + directories for a URL that still exists in 90 days.
- Same week as PH is fine. Same hour is not.
Ready? Ship the demo, then list on ScrollLaunch the same week. Need first paying users from the spike? First 10 customers.
