Reddit vs Hacker News for Launching Your Product

Hacker News is a tightly focused community of developers, engineers, founders, and tech enthusiasts. The audience is small but incredibly influential — a front-page HN post can drive tens of thousands of visits from exactly the right people if you're building a technical product.

Reddit's tech communities overlap with HN's audience, but Reddit also gives you access to non-technical communities. If your product has broad appeal beyond developers, Reddit opens doors that HN simply can't.

On Hacker News, there's a single front page. Every submission competes for the same 30 spots, and the ranking algorithm considers both upvotes and time. A post that doesn't gain traction in the first hour is effectively dead. There are no subreddit equivalents — it's one pool for everyone.

Reddit's structure is fundamentally different. With thousands of subreddits, you can target specific communities where your product is most relevant. A post in a 50K-member niche subreddit can drive highly qualified traffic even if it only gets 50 upvotes. You also get multiple shots — you can post to different subreddits over days or weeks.

HN favors technical depth and intellectual honesty. The best-performing launch posts are 'Show HN' submissions that demonstrate genuine technical innovation. HN users want to see what's under the hood: your architecture decisions, the interesting engineering problems you solved, and what makes your approach novel.

Avoid marketing language entirely. Words like 'revolutionary,' 'disruptive,' or 'game-changing' will get you downvoted immediately. Instead, be specific and technical: 'Show HN: I built a Postgres extension that reduces query latency by 40% for time-series data.'

Reddit rewards authenticity and storytelling. The most successful launch posts share a personal journey: the problem you experienced, what you tried, why existing solutions fell short, and how you built something better. Reddit users want to connect with you as a person, not evaluate your technical architecture.

Different subreddits have different expectations. In r/startups, share business metrics and lessons learned. In r/webdev, focus on the technical stack and challenges. In r/SideProject, emphasize the personal journey. Tailor your message to each community.

A successful HN front-page post delivers a massive spike: potentially 20,000-50,000 visits in a single day. But this drops off rapidly — within 48 hours, traffic returns to near zero. The long tail is minimal unless your post gets archived on popular aggregator sites.

Reddit traffic is more distributed. A successful post might drive 2,000-10,000 visits initially, but Reddit posts get indexed by Google and can continue driving traffic for months. Multiple posts across different subreddits compound this effect. Over a quarter, Reddit often delivers more total traffic than a single HN spike.

If you're building a highly technical product (developer tools, open-source projects, infrastructure), start with Hacker News. The audience is perfectly matched and a front-page post provides instant credibility in the tech community.

If your product serves a broader audience or solves a non-technical problem, start with Reddit. The ability to target specific communities means higher conversion rates, even if the total traffic is lower.

For the best results, use both. Launch on HN first (if your product has technical merit), then expand to Reddit with a community-by-community approach over the following weeks. The HN social proof actually helps on Reddit: 'After hitting the HN front page, here's what we learned about launching a product.'
