Platform-by-platform playbook for launching developer tools and technical products. Not generic social media advice -- the specific tactics that work on each channel, from someone who has seen hundreds of dev tool launches succeed and fail.
When to Use
Use for:
Planning a multi-channel launch for a developer tool or technical product
Understanding community norms before posting to a new platform
Timing and formatting a post for maximum reach on a specific channel
Coordinating a launch day across multiple platforms
Recovering from a botched launch or planning a re-launch
Do NOT use for:
Writing the actual announcement copy (use product-announcement-craft)
SEO and blog content strategy (use seo-content-blogging)
Paid advertising or enterprise marketing campaigns
General social media management for non-technical products
The Launch Day Sequence
Post to channels in this order. Each channel has different peak windows and the order matters because early traction on one feeds momentum on others.
06:00 AM ET - Hacker News (Show HN)
08:00 AM ET - Twitter/X thread
09:00 AM ET - LinkedIn post
10:00 AM ET - Dev.to article
12:00 PM ET - Reddit (r/SideProject, then niche subs)
02:00 PM ET - Indie Hackers
Evening - Facebook groups
Next day - Product Hunt (if using PH, make it its OWN day)
Product Hunt resets daily at 12:01 AM PT. Launch it on a SEPARATE day from your HN push so you can give each platform full attention.
Hacker News (Show HN)
Reach potential: 500K-2M+ impressions if front page
Best for: Technical tools, open source, anything builders appreciate
Culture: Meritocratic, skeptical, hates marketing speak
Timing
Best days: Tuesday, Wednesday, Thursday
Best time: 6:00-8:00 AM ET (US morning, before front page fills up)
Avoid: Weekends (lower traffic), Fridays (people check out), major tech news days
Title Format
Show HN: <Name> - <What it does in plain English>
GOOD: Show HN: Windags - DAG orchestration for multi-agent workflows
GOOD: Show HN: I built a CLI that turns natural language into parallelized agent calls
BAD: Show HN: Introducing Windags - The Future of AI Orchestration (tm)
BAD: Show HN: We're excited to announce our new platform
Rules:
"Show HN:" prefix gets your post on /show (less competitive than front page)
Title must be factual and specific -- no superlatives, no marketing language
No company names without explaining what the thing does
Technical detail is good: "written in Rust" or "uses SQLite" adds credibility
The First Comment (Critical)
Immediately post a comment on your own submission. This is your one chance to tell the story:
Template:
Hey HN, I'm [name]. I built [thing] because [genuine problem you had].
[1-2 sentences on how it works technically]
[What makes this different from X, Y, Z alternatives]
I'd love feedback on [specific question]. The code is at [repo link].
What works: Honesty about limitations, technical depth, asking for specific feedback
What kills you: Marketing speak, ignoring criticism, defensive responses
Engagement Rules
Respond to EVERY comment in the first 2 hours
When criticized, find something to agree with first
Never say "great question!" -- just answer it
Upvotes from direct links do NOT count (HN detects vote rings)
Ask friends to find your post on /newest and upvote organically
Second Chances
You get ONE launch. A re-post only works if you have something substantially new (major feature, open-sourced it, pivoted). Wait at least 3-6 months.
Product Hunt
Reach potential: 10K-100K visitors on launch day
Best for: Polished tools with visual demos, products targeting early adopters
Culture: Supportive, upvote-driven, rewards preparation and community engagement
Pre-Launch (Start 4-8 Weeks Before)
Build your Product Hunt profile -- upvote and comment on 20+ products
Find a Hunter with 1,000+ followers (reach out personally, explain your product)
Build an email list of 200+ people who will support launch day
Create all assets: 6 images (1270x760), a GIF or video, compelling tagline
Timing
Best days: Tuesday, Wednesday, Thursday (data shows highest engagement)
Launch time: 12:01 AM PT (when the daily cycle resets)
Block your entire launch day -- set 30-minute timers to check for comments
Critical Success Factor: First 4 Hours
Launches that cross 100 upvotes before 4:00 AM PT have an 82% chance of finishing Top 10. This means your email list and personal network must be activated the moment you launch.
The Listing
Tagline: [verb] + [what] + [benefit] (under 60 chars)
GOOD: "Build AI workflows with drag-and-drop DAGs"
BAD: "The revolutionary AI platform for the future"
First Comment:
- Who you are and why you built this
- What problem it solves (be specific)
- What's free vs paid
- Ask for specific feedback
Asset Checklist
6 gallery images (1270x760px) -- show the product, not marketing fluff
30-60 second demo video or GIF
Tagline under 60 characters
Description (paragraph format, not bullet points on PH)
Maker comment drafted and ready
Hunter confirmed and briefed
Launch day email drafted for your list
Engagement
Respond to every comment within 15 minutes
Thank upvoters personally (they get notified)
Share progress updates throughout the day ("We just hit #3!")
Never ask for upvotes directly -- ask people to "check it out and share feedback"
Reddit
Reach potential: Varies wildly by subreddit (1K to 1M+)
Best for: Authentic stories, technical deep-dives, "I built this" narratives
Culture: Allergic to self-promotion, rewards genuine contribution
The 90/10 Rule
For every 1 self-promotional post, you need 9 genuine contributions (comments, helpful answers, sharing others' work). Build 200-300 karma before any product mentions.

Post Format That Works
Title: I spent 6 months building [X] - here's what I learned
Body:
- The problem you had (relatable)
- What you tried first (shows effort)
- How you built the solution (technical detail)
- What surprised you (honest reflection)
- Link to project (at the END, not the beginning)
- "Happy to answer questions about [specific technical topic]"
What Gets You Banned
Posting the same thing to 10 subreddits simultaneously
Account that only posts about your own product
Asking friends to upvote (Reddit detects brigading aggressively)
Posting a link with no context or story
Twitter / X
Reach potential: 10K-500K impressions with a good thread
Best for: Build-in-public narratives, demo videos, connecting with developer influencers
Culture: Rewards visual content, hot takes, and authenticity
Thread Format (Launch Announcement)
Tweet 1 (Hook): Bold claim or surprising result
"I replaced 4 hours of manual agent coordination with a 30-second DAG."
Tweet 2: The problem (relatable pain)
Tweet 3: The solution (what you built, with screenshot or GIF)
Tweet 4: How it works (technical but accessible)
Tweet 5: Demo video or GIF (60 sec max)
Tweet 6: What's next + call to action
Tweet 7: Link to try it
Final tweet: "If this was useful, follow me for more [topic] content"
Timing
Best days: Tuesday-Thursday
Best time: 8:00-10:00 AM ET (US developer morning)
Tweet 1 goes out at peak time; rest of thread is already written and posted as a thread
Engagement Tactics
Quote-tweet people who share your launch (more visibility than a reply)
Reply to every comment in the first hour
Pin the launch thread to your profile
Tag relevant people in replies (not in the thread itself -- that's spammy)
Post a standalone demo GIF 2-3 days after the thread (catches different audience)
What NOT to Do
Don't tag 10 influencers in your launch tweet
Don't use hashtags (developer Twitter ignores or mocks them)
Don't just post a link -- always add context, a screenshot, or a take
Don't thread more than 7-8 tweets -- attention drops after that
LinkedIn
Reach potential: 5K-200K impressions for good content
Best for: Professional narrative, "lessons learned" format, B2B developer tools
Culture: Professional but increasingly authentic, rewards storytelling
Post Format
[Hook line that stops the scroll - personal, surprising, or contrarian]
[Blank line]
[2-3 short paragraphs telling the story]
[Blank line]
[Bullet list of key takeaways or lessons]
[Blank line]
[Call to action - try it, follow for more, link in comments]
Timing
Best days: Tuesday, Wednesday, Thursday
Best time: 8:00-10:00 AM in your audience's timezone
LinkedIn's algorithm identifies subject-matter experts and boosts their content to relevant audiences
Key Rules
Put the link in the FIRST COMMENT, not in the post (LinkedIn suppresses posts with external links)
1,200-2,000 characters performs best
Carousels and PDFs get more reach than video (LinkedIn deprioritized video in 2025)
Personal stories outperform corporate announcements
Write as a person, not a brand
What Works for Dev Tool Launches
GOOD: "I spent 6 months building something nobody asked for. Here's why I don't regret it."
GOOD: "3 things I learned launching a developer tool with zero marketing budget"
BAD: "Excited to announce the launch of our new platform!"
BAD: "We're hiring! Also check out our new product"
Dev.to
Reach potential: 5K-50K views for featured articles
Best for: Technical tutorials, architecture deep-dives, "how I built this" posts
Culture: Developer-first, educational, supportive of new tools
Article Format
Title: "How I Built X with Y" or "X: A Better Way to Do Y"
Include a cover image (1000x420px)
Use proper markdown with code blocks
Tag appropriately (max 4 tags): the tech stack tags + relevant topic tags
Cross-post from your blog (Dev.to supports canonical URLs for SEO)
Timing
Best days: Monday-Wednesday (developer reading time)
Best time: 7:00-9:00 AM ET
Promotion Rules
The article must be genuinely educational, not just an ad
Show code, show architecture decisions, show tradeoffs
End with a link to the project but make the article valuable on its own
Engage with comments -- Dev.to community rewards responsiveness
Indie Hackers
Reach potential: 1K-20K views, but 23% conversion rate per engaged post
Best for: Revenue stories, build-in-public updates, asking for feedback
Culture: Founder-friendly, loves transparency, especially revenue numbers
What Performs Best
Journey posts with specific numbers outperform everything else:
GOOD: "From $0 to $2.4K MRR in 90 days -- how I launched [X]"
GOOD: "I got 500 signups in a week. Here's the exact playbook."
BAD: "Check out my new developer tool!"
BAD: "Announcing [product name]"
Post Structure
The hook (result or surprising number)
Context (what you built and why)
The specific tactics (what you did, step by step)
The numbers (traffic, signups, revenue -- be specific)
What failed (honesty builds trust)
What's next + ask for feedback
Timing
Post Tuesday-Thursday for best engagement
Engage in other threads for 2-4 weeks before your launch post
Facebook Groups
Reach potential: 500-5K per group, but highly targeted
Best for: Niche communities, local tech scenes, framework-specific groups
Culture: Varies wildly by group -- read the rules first
Key Groups for Dev Tools
JavaScript / TypeScript / React groups (for frontend tools)
AI/ML practitioner groups (for AI tools)
Indie Hackers and solopreneur groups
Framework-specific groups (Next.js, Svelte, etc.)
Rules
Almost all groups prohibit direct self-promotion
Share a useful insight or tutorial, mention your tool as context
Ask for feedback, not downloads
Never cross-post the same thing to 10 groups on the same day
Anti-Patterns
1. Shotgun Blast Launch
Mistake: Posting to all channels simultaneously with the same copy-paste message.
Fix: Tailor each post to the platform's culture and format. Stagger over 2-3 days.
2. Launch and Disappear
Mistake: Posting your launch and not checking back for 8 hours.
Fix: Block your entire launch day. Respond to every comment within 30 minutes.
3. Begging for Upvotes
Mistake: Sending direct links to friends asking them to upvote on HN or PH.
Fix: On HN, tell people to find your post on /newest. On PH, ask people to "check it out." Both platforms detect and penalize vote manipulation.
4. Marketing Speak on Technical Platforms
Mistake: "We're thrilled to announce our revolutionary AI-powered platform."
Fix: "I built a CLI that turns prompts into parallel agent workflows. Here's how it works."
5. Ignoring Criticism
Mistake: Defensive replies or ignoring negative feedback.
Fix: Thank critics, find something to agree with, explain your thinking. The audience watches how you handle criticism more than the criticism itself.
6. One Launch, Done Forever
Mistake: Treating launch as a single event.
Fix: Launch day is day 1. Follow up with technical blog posts, case studies, changelog updates, and "3 months later" retrospectives on each channel.
7. Wrong Channel for Your Product
Mistake: Launching a B2B enterprise tool on r/SideProject, or a hobby project on LinkedIn.
Fix: Match channel to audience. HN and Reddit for technical builders. LinkedIn for B2B. PH for early adopters. Indie Hackers for solo founders.
Quality Checklist
Each platform post is written specifically for that platform's culture and format
Timing is planned for each channel's peak engagement window
You have 200+ karma on Reddit before posting (if using Reddit)
