where to publish launch announcement for dev tool

Good places to publish a dev tool launch announcement, in roughly best-to-broadest order:

High-signal places

• Product Hunt — best for early adopters and launch-day buzz.
• Hacker News — great if the tool is genuinely useful, technical, or novel.
• Reddit — relevant subreddits like:
  • r/programming
  • r/devtools
  • r/webdev
  • r/opensource
  • language/framework-specific subs
• Dev.to — good for developer-focused posts and tutorials.
• Indie Hackers — useful if you want builder/founder feedback.

If your tool is open source

• GitHub — pin the repo, write a strong README, add a release.
• Awesome lists / community lists — if there are relevant curated lists.
• Open-source newsletters / directories — depending on category.

If it’s niche-specific

• Slack/Discord communities in your niche
• LinkedIn if it’s B2B/dev productivity and your audience is there
• X (Twitter) for reach, especially if you have existing followers

Don’t forget your own channels

• Blog / changelog
• Email list
• Docs homepage / landing page
• In-app announcement if you already have users

Best practice

Tailor the announcement to each platform:

• HN: technical, honest, no hype
• Product Hunt: polished, concise, value-focused
• Reddit: community-first, no heavy self-promo
• Dev.to/Blog: include story, use case, and examples

If you want, I can also give you:

2. a template announcement post, or
3. the best channels based on your specific dev tool type.
