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 are some of the highest-reach free channels there are. A good "Show HN" can send thousands of visitors in an afternoon; the right Reddit thread can find you your most passionate early users. They're also the easiest to get wrong, because these communities have finely tuned spam detectors and long memories. Here's how to do it right.
Hacker News (Show HN)
Hacker News is a meritocracy with no paid placement, which is exactly why it's valuable. To launch well:
- Title it plainly: "Show HN: [what it is]." No hype, no adjectives.
- Link to a working demo people can try without a signup wall if at all possible.
- Write a short first comment explaining why you built it and what's genuinely hard about it.
- Stay in the thread and answer everything, including criticism, candidly.
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.
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.
Niche communities
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.
The bottom line
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 The Runway.
