When to choose Reddit: Volume and community
Reddit is better when you need reach, community building, or targeting specific developer niches. Here are the scenarios where Reddit consistently outperforms Hacker News, with real examples.
Open Source Projects and Libraries
Reddit has dedicated communities for every programming language and framework. r/programming (3.2M members), r/javascript (2.8M), r/python (1.4M) actively discuss new libraries and tools. Post releases, tutorials, and ask for feedback without the "Show HN" gatekeeping.
Real example: React Query launch on r/reactjs got 4,200 upvotes, 380 comments, and 67K visits. Same-day HN post: 180 points, 45 comments, 12K visits. Reddit drove 5.6x more traffic and 3x more GitHub stars in first week. Expect 2,000-10,000 visits for front-page posts in major language subreddits, with 8-12% conversion to GitHub stars.
Example of a successful open source library post on Reddit:
- Shared state across components with a single hook call
- TypeScript-first, full type inference out of the box
- No context providers, no store setup
- Selector support for re-render optimization
- ~800 bytes min+gzip**How it works:** Uses useSyncExternalStore under the hood (the same primitive Zustand uses). The entire source is about 60 lines.**GitHub:** [link]
**npm:** [link]
**CodeSandbox demo:** [link]I know the world doesn't need another state lib, but this scratched an itch. Curious if the API feels right or if I'm missing obvious footguns. Also — should I add middleware support or keep it dead simple?
This post performs well on Reddit because it's specific about the problem, shows technical details, includes a demo, and asks for genuine feedback. The casual tone and self-deprecating question ("am I reinventing the wheel?") fits Reddit's culture.
Consumer Developer Tools (Individual Users)
For tools targeting individual developers (not enterprises), Reddit provides better reach and adoption. Code editors, terminal tools, browser extensions, and productivity apps perform exceptionally well. HN audience skews toward infrastructure and B2B tools with enterprise budgets.
Real example: Warp terminal launch on r/programming drove 34K visits and 8,900 waitlist signups (26% conversion). HN Show HN: 11K visits, 1,800 signups (16% conversion). Reddit drove 3x more signups despite lower conversion rate due to volume advantage. Front-page posts in r/programming or r/webdev drive 15K-50K visits with 15-25% signup conversion for free tools.
Long-Term Community Building
Reddit allows ongoing participation in niche communities. Build reputation through consistent helpful comments over months. Subreddit members recognize regular contributors. HN doesn't have persistent communities—each post stands alone, no community memory.
Real example: Supabase spent 6 months building karma in r/webdev and r/selfhosted before launching. When they posted their Show HN equivalent on Reddit, community recognized them: "Oh it's the Supabase team, they've been super helpful here." Post hit #1, stayed front page 18 hours vs typical 4-6 hours. Build 500+ karma in target subreddit over 2-3 months—launch posts from recognized accounts get 2-3x more upvotes and stay visible longer.
When to choose Hacker News: Quality and authority
Hacker News is better when you need decision-makers, technical credibility, or high-value conversions. Here are the scenarios where HN consistently outperforms Reddit, with real conversion data.
B2B Infrastructure and DevOps Tools
HN audience includes CTOs, engineering leaders, and senior engineers with purchasing power. 60-70% of HN readers are in decision-making roles vs 15-20% on Reddit. Better for databases, monitoring tools, CI/CD platforms, and enterprise infrastructure. Reddit's audience skews younger with less budget authority.
Real example: PlanetScale launch on HN drove 14K visits, 420 signups, and 47 enterprise trials ($2K+/month). Reddit r/programming: 31K visits, 890 signups, 8 enterprise trials. HN converted to enterprise at 5.9x higher rate despite 2.2x less traffic. Front-page Show HN drives 8K-25K visits with 2-4% enterprise trial conversion (vs 0.3-0.8% on Reddit) and 3-5x higher average deal size.
Example of HN-style technical post (works better on HN than Reddit):
- OpenTelemetry SDK for instrumentation (auto + manual)
- OTLP receiver for data ingestion
- ClickHouse for storage (columnar, handles high cardinality well)
- Built-in dashboards for Golang, Redis, PostgreSQL, MySQL host metrics
- Alerting via email, Slack, PagerDutyKey tradeoff vs Datadog/New Relic: you self-host and manage ClickHouse, but you avoid per-host pricing. For us at 50M spans/day the infrastructure cost is under $500/month vs $15K+/year on commercial APM.GitHub: github.com/uptrace/uptraceHappy to answer questions about the architecture.
This post works on HN because it's deeply technical, includes specific metrics and cost breakdowns, and shows architectural thinking. Reddit would want a shorter, more accessible version. HN readers appreciate the depth and detail.
Technical Deep-Dives and Postmortems
HN readers appreciate technical depth and reward it with engagement. Detailed architecture posts (2,000+ words), scaling challenges with specific metrics, and incident postmortems with root cause analysis perform exceptionally well. Reddit prefers shorter, more accessible content (800-1,200 words max).
Real example: Cloudflare's "How we built a 1.1.1.1 DNS resolver" (3,400 words) hit HN #1 for 12 hours with 380 points, 180 comments, and 67K visits. Same post on r/programming: downvoted for "too technical," 40 upvotes, 8 comments. HN readers engaged deeply; Reddit wanted TL;DR. Technical deep-dives (2,000+ words) on HN get 200-400 points and 100+ comments. Same content on Reddit gets 50-150 upvotes unless heavily simplified.
Startup Launches and Funding Announcements
HN is the default platform for YC companies and tech startups. Launch posts, Show HN submissions, and funding announcements reach investors, potential acquirers, and technical early adopters. Reddit doesn't have equivalent startup-focused attention or investor presence.
Real example: Replit's "We raised $80M Series B" on HN: 890 points, 340 comments, 12 investor emails, 3 acquisition inquiries. Same announcement on Reddit r/startups: 180 upvotes, 45 comments, zero investor contact. HN has the decision-makers; Reddit has the spectators. Startup launches on HN front page reach 50-100 angel investors and 10-20 VCs. Expect 5-15 investor emails for compelling stories. Reddit drives awareness but not investor interest.

Content strategy differences: What works on each platform
Each platform requires fundamentally different content approaches. What succeeds on Reddit often fails on HN, and vice versa. Here's what actually works, with real examples.
Reddit content strategy: Community-first approach
Reddit success requires building community trust before promoting. The 9:1 rule isn't optional—it's survival. Subreddit mods track your post history and ban accounts that only self-promote.
- Follow the 9:1 rule religiously: 9 helpful comments for every 1 promotional post. Build 500+ karma in target subreddit before posting your product.
Real example: Spent 3 weeks answering questions in r/webdev. Built 680 karma. When I posted "I built a Chrome extension for debugging," community recognized me: "Oh it's the person who helped me with that React issue!" Post hit front page, stayed there 8 hours.
- Target niche subreddits strategically: r/webdev (1.5M), r/javascript (2.8M), r/devops (250K). Smaller subreddits (10K-100K) often convert better—less noise, more engaged community.
Real example: Posted Kubernetes tool to r/kubernetes (250K members): 890 upvotes, 4,200 visits, 340 signups. Same post to r/programming (3.2M): 120 upvotes, buried in noise. Niche subreddits = better targeting.
- Use "I built this" framing: Tutorials, "I built this" posts, comparison guides. Frame as sharing your journey, not promoting a product. Reddit rewards vulnerability and learning stories.
Winning title: "I spent 6 months building a tool to solve [problem]. Here's what I learned." vs "Check out our new tool for [problem]" (gets downvoted immediately).
- Engage in comments within 2 hours: Answer every question, provide code examples, share experience. Posts with active OP engagement stay on front page 2-3x longer.
Hacker News content strategy: Technical depth wins
HN rewards technical sophistication and punishes marketing speak. The community can smell promotion from a mile away. Lead with substance, not hype.
- Lead with technical depth: Architecture decisions, performance optimizations, lessons learned. 2,000+ word deep-dives outperform short posts 10:1.
Real example: "How we reduced database query time from 2.3s to 47ms" (2,800 words with code samples): 420 points, #1 for 9 hours. Same topic as 400-word summary: 12 points, dead in 30 minutes. HN rewards depth.
- Use Show HN correctly: "Show HN: [Product Name] – [What it does in 3-5 words]". No superlatives. No marketing claims. Just facts.
Good: "Show HN: Postgres query optimizer using ML" vs Bad: "Show HN: Revolutionary AI-powered database tool that will change everything" (gets flagged).
- Participate in comments immediately: Add technical insights, share relevant experience, answer questions. Founders who engage in comments get 2-3x more upvotes and stay on front page longer.
- Avoid all marketing language: No "revolutionary," "game-changing," "best-in-class." Use plain technical language. Let the product speak for itself through technical merit.
Traffic quality analysis
Traffic volume doesn't equal traffic value. Here's what to expect from each platform.
Reddit Traffic
- Average session: 2-4 minutes
- Bounce rate: 60-80%
- Pages per session: 1.2-1.5
- Mobile traffic: 70%
- Best for: Brand awareness, traffic volume
Hacker News Traffic
- Average session: 5-10 minutes
- Bounce rate: 40-60%
- Pages per session: 2.5-3.5
- Mobile traffic: 40%
- Best for: Qualified leads, conversions
The decision framework: Which platform for your product
The choice between Reddit and Hacker News isn't about which platform is "better"—it's about which metric matters more for your specific product and growth stage. Here's the strategic framework I use for every launch.
The Three-Question Framework
Q1 — What's your primary goal?
Volume / Awareness
→ Reddit. You need eyeballs and brand recognition. Conversion rate matters less than reach.
Quality / Revenue
→ Hacker News. You need decision-makers and paying customers. Traffic volume matters less.
Q2 — Who's your ideal customer?
Individual developers
→ Reddit. Broader reach, more junior developers, higher volume adoption.
Engineering leaders
→ Hacker News. CTOs, VPs of Engineering, senior engineers with budget authority.
Q3 — What's your content depth?
Accessible / Tutorial
→ Reddit. 800–1,200 words. Community prefers digestible content with clear takeaways.
Technical / Deep-dive
→ Hacker News. 2,000+ words. Audience rewards depth and technical sophistication.
Recommendation by product type
Based on 30+ launches, here's which platform works best for each product category, with expected metrics.
B2B Infrastructure Tools → Hacker News Primary
Databases, monitoring, CI/CD, cloud infrastructure. HN audience has budget and authority. Share technical architecture posts and Show HN launches. Use Reddit secondarily for specific technical subreddits (r/devops, r/kubernetes). Expected: 8K-25K visits, 2-4% enterprise conversion, $2K-$10K MRR average deal.
Developer Productivity Tools → Reddit Primary
Code editors, terminal tools, browser extensions. Reddit's broader reach helps with adoption. Target r/webdev (1.5M), r/programming (3.2M), r/javascript (2.8M). Use HN for major launches only. Expected: 15K-50K visits, 15-25% free signup, 2-5% paid conversion.
Open Source Projects → Both Platforms
Use Reddit for community building and ongoing engagement. Use HN for major releases and technical deep-dives. Both platforms value open source contributions. Reddit drives GitHub stars (volume), HN drives quality contributors. Reddit delivers 3-5x more stars, HN delivers 2-3x more PRs. Combined strategy yields best results.
API Products & Developer Platforms → Hacker News Primary
APIs, developer platforms, and technical services. HN audience is more likely to integrate and pay for APIs. Share technical documentation, architecture decisions, and scaling challenges. Reddit audience less likely to adopt paid APIs. Expected: 10K-30K visits, 5-10% API signup, 8-15% paid tier conversion.
Managing ban risk on both platforms
Both communities punish self-promotion. Here's how to stay safe.
Reddit Ban Prevention
Build karma first. Accumulate 500+ comment karma before posting promotional content. Reddit mods track your post-to-comment ratio and ban accounts that only self-promote.
Read subreddit rules carefully. Each subreddit has different self-promotion policies. Some allow it on specific days, others ban it entirely. Violating rules gets you permanently banned.
Use "I built this" framing. Frame posts as sharing your journey, not promoting a product. "I spent 6 months building..." performs better than "Check out our product."
Engage actively. Respond to every comment within first 2 hours. Posts with active OP engagement stay on front page 2-3x longer. Never delete and repost—mods track this and will ban.
Hacker News Flag Prevention
Lead with technical substance. Marketing language triggers immediate flags. Use plain technical language and let the product speak through technical merit.
Avoid superlatives. "Revolutionary," "game-changing," and "best-in-class" get flagged. Use factual descriptions instead.
Respond professionally to criticism. Acknowledge valid points, explain technical constraints, commit to improvements. Founders who engage with criticism convert 2-3x better.
Limit self-promotion. Don't submit your own domain more than once per month. Participate in comments on other posts to build credibility before posting your own content.
The hybrid strategy (recommended)
Most successful tech companies use both platforms strategically.

What to track on each platform
Track these metrics to measure effectiveness on each platform.
Reddit Metrics
Upvote ratio (aim for 85%+), comment engagement rate (how many comments per upvote), traffic to website (UTM: source=reddit), subreddit-specific karma (build reputation in target communities), and time to front page of subreddit (faster = better algorithm performance).
Hacker News Metrics
Points (aim for 100+ for front page), comment depth and quality (engaged technical discussions), traffic to website (UTM: source=hackernews), time on front page (longer = more visibility), and conversion rate (HN traffic converts 2-3x better than Reddit).
Common mistakes that kill your launch
I've made every one of these mistakes. Some cost me thousands in wasted traffic, others got me banned. Here's what to avoid and why it matters.
Posting the same content to both platforms
Reddit and HN have fundamentally different content preferences. Same post = different results. Reddit prefers accessible tutorials (800-1,200 words). HN prefers technical depth (2,000+ words). Adapt or fail.
My mistake: Posted identical 900-word tutorial to both platforms. Reddit: 340 upvotes, front page. HN: 8 points, dead in 20 minutes. Comments: "This is too basic for HN." Should have written 2,500-word technical deep-dive for HN.
Only posting, never commenting (Reddit death sentence)
Reddit mods track your post-to-comment ratio. Accounts that only post promotional content get shadowbanned. Build reputation through helpful comments before posting your own content. The 9:1 rule isn't optional.
My mistake: Created new account, posted product to 5 subreddits same day. Banned from 4/5 within 24 hours. Mod message: "Your account only posts promotional content. Permanent ban." Lost 3 weeks of work. Should have spent 2-3 weeks commenting first.
Using marketing language (instant flag on HN)
"Revolutionary," "game-changing," "10x better," "best-in-class" trigger immediate downvotes and flags. Both communities can smell marketing from a mile away. Use plain, technical language. Let the product speak for itself through technical merit.
My mistake: HN title: "Show HN: Revolutionary AI tool that will transform your workflow." Flagged dead within 45 minutes. Reposted week later: "Show HN: SQL query optimizer using transformers." 280 points, front page 6 hours. Same product, different framing.
Ignoring negative feedback (missed opportunity)
Both communities respect founders who engage with criticism professionally. Respond to negative comments within 1-2 hours. Acknowledge valid points, explain technical constraints, commit to improvements. Posts with active founder engagement convert 2-3x better.
My mistake: HN post got critical comment: "This doesn't solve [specific problem]." Ignored it. Comment got 40 upvotes, became top comment, killed momentum. Should have responded: "You're right, here's our thinking on that limitation and our roadmap." Engagement = credibility.
Posting at the wrong time (timing kills reach)
Both platforms have optimal posting windows. Reddit: 8-10am ET weekdays (US morning). HN: 9-11am ET weekdays (catches US morning + Europe afternoon). Weekend posts get 40-60% less engagement. Timing matters as much as content quality.
My mistake: Posted Show HN at 11pm ET Friday. Got 12 points, dead by Saturday morning. Reposted same content Tuesday 9am ET: 340 points, front page 8 hours. Timing difference = 28x more points. Always post during US business hours.
Reddit in its early days solved the chicken and egg problem by using fake users to post content. Growth is a rigorous, scientific discipline.
