Show HN, Reddit, and Free Communities: A Launch-Day Playbook
Community launches are free and powerful, and easy to get wrong. Here's how to launch on Hacker News, Reddit, and niche communities without getting flamed.
Community launches on Hacker News, Reddit, and niche communities are free and high-reach, but only work when you show up as a member first: a plain honest title, a working demo, and staying present in the comments after posting. These communities have finely tuned spam detectors and long memories, so shortcuts backfire fast.
How do you launch well on Hacker News?
Hacker News is a meritocracy with no paid placement, which is exactly why it's valuable. To launch well:
| Do | Why |
|---|---|
| Title plainly: "Show HN: [what it is]" | No hype, no adjectives, matches community norms |
| Link to a working demo, no signup wall if possible | Reduces friction to actually trying it |
| Write a short first comment on why you built it | Sets an honest, substantive tone |
| Stay in the thread and answer everything | Vanishing reads as disrespect for the room |
Hacker News rewards honesty and substance. The fastest way to fail is to sound like a press release. Talk like an engineer explaining your work to peers.
What's the right way to launch on Reddit?
Reddit can be gold or a graveyard depending entirely on how you show up. Find the subreddit where your users already are, r/SaaS, r/startups, or a niche community for your space, and read the rules before you post. Use the designated threads: many subs run weekly "Share Your Startup" posts made for exactly this. Then share your story, what you built and why, not a pitch. Be helpful in other threads too; contribution earns you the right to promote.
What about niche communities beyond the big two?
Beyond the big two, the highest-intent audiences are often in smaller rooms: a Discord for your niche, a Slack community, an Indie Hackers group. These convert better precisely because they're focused. The rule is the same everywhere: be a member first, a marketer second. Our guide on launching with no audience covers how to find and warm up these rooms before launch day.
So what should you actually do?
Community launches are free, powerful, and unforgiving of shortcuts. Lead with honesty, respect the room, and stick around after you post. Then capture the momentum with a permanent home: list free on LaunchFree.io.
