Hacker News is where technical founders and early adopters gather. It is not Reddit: threads move fast, norms are stricter, and substance beats hype. This playbook covers Show HN, Ask HN, and ongoing discovery - without treating HN as a billboard.
Read HN Guidelines before your first post. For Reddit tactics: Reddit playbook. For HN-specific landing: Hacker News customer discovery.
What HN is good for
| Use case | Format | Outcome |
|---|---|---|
| Launch spike | Show HN | Feedback, traffic, technical critique |
| Language mining | Ask HN threads | How buyers describe workflows |
| Competitive intel | Comment threads on "alternatives to X" | Positioning, objections |
| Hiring signal | "Who is hiring" / culture threads | Market maturity (not direct sales) |
HN is weaker for: consumer lifestyle products, heavy visual brands, and anything that needs long video before understanding the product.
Show HN: what still works in 2026
- Title = what it is - "Show HN: Open-source cron for Kubernetes" beats "Show HN: We reimagined scheduling."
- Link to something usable - demo, repo, or landing page with a clear first action.
- Be in the comments for hours - the thread is the tour; lurkers watch how you respond.
- Accept blunt feedback - defensive replies age poorly in search and memory.
- One Show HN per major milestone - do not re-post the same launch weekly.
Common failures:
- Vaporware landing page with no demo
- Founders who disappear after posting
- Marketing speak in the first comment
- Asking friends to upvote (against HN rules)
Ask HN: your best discovery surface
Ask HN posts often start with "How do you…?" or "What do you use for…?" Those threads are natural discovery for B2B and dev tools:
- Search HN for your category (observability, CI, note-taking, billing)
- Read top-level comments for phrases to reuse on your site
- Note alternatives people compare - you are learning positioning, not closing in-thread
Comment-first discovery: Before you post Ask HN, spend two weeks leaving useful replies on existing threads. HN accounts with zero history promoting a product get flagged.
Show HN vs Ask HN (decision tree)
Do you have a working demo or OSS repo?
├─ No → Ask HN for workflow research OR keep building
└─ Yes → Is this your first public launch?
├─ Yes → Show HN (block 4+ hours for comments)
└─ No → Is the update a major new capability?
├─ Yes → Show HN with honest "what changed"
└─ No → Comment on relevant threads instead
Timing and cadence
Posting when the front page is active helps visibility. Use the free Best Time to Post on Hacker News tool to review recent activity by hour (UTC) and trending keywords - then pick a window that fits your timezone and team availability.
Practical note: Tuesday–Thursday mornings US time often see high traffic, but your comment quality matters more than the perfect hour.
Engagement templates (adapt, do not spam)
Helpful comment on an Ask HN thread
We hit this when [specific context]. Two things that helped:
1. [Concrete tip]
2. [Concrete tip]
Happy to share how we approached [narrow sub-problem] if useful.
Show HN first comment (maker comment)
Hi HN - [name], builder here.
Problem: [one sentence]
What we built: [one sentence]
Try it: [link]
Known limitations: [honest list]
Looking for feedback especially on [specific area].
Disclose affiliation. Answer technical questions with specifics - benchmarks, architecture tradeoffs, pricing logic.
Turn HN into a weekly workflow
| Day | Action |
|---|---|
| Mon | Search HN + Reddit for 3 category phrases; log new threads |
| Wed | 2 substantive comments (no product link unless asked) |
| Fri | Update positioning doc with new phrases from threads |
When manual search becomes repetitive, run the same queries across HN and Reddit in one pass - Needle Search includes Hacker News on eligible plans. Free Trending Problems shows category-wide momentum without an account.
Metrics that matter
| Metric | Why |
|---|---|
| Qualified comments | Technical questions = real evaluators |
| Follow-up DMs / emails | People who want to try it |
| Sign-ups with source=HN | Use UTM or "how did you hear" |
| Second-order links | Blog posts citing your Show HN thread |
Upvotes alone are vanity - a front page with zero signups usually means positioning or onboarding failed, not "bad luck."
