Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • Be Respectful: Treat all members with respect. No harassment, hate speech, or personal attacks will be tolerated. Be constructive in your feedback and interactions.
  • Stay on Topic: All posts should be related to "building in public," whether you're working on a product, learning a new skill, or launching something new. Off-topic content will be removed.
  • No Self-Promotion Without Context: Share your work openly, but avoid posting solely for self-promotion. Instead, focus on sharing progress, lessons learned, and asking for feedback.
  • No Spam: Spamming links, irrelevant content, or unsolicited advertisements will lead to immediate removal. Keep the focus on building and learning together.
  • No Plagiarism or Misrepresentation: All work shared should be your own or properly credited if you’re collaborating or using third-party resources. Misrepresenting work as your own will result in immediate action from the moderators.
  • Privacy: Do not share private or sensitive information about yourself or others without consent. This includes sharing someone else's work without permission.
  • Transparency in Tools & Resources: If you share tools or resources, be transparent if they’re paid, free, or affiliate-linked. This helps maintain trust and clarity in the community.

Works well

  • A build log post covering what you shipped this week, what failed, and what you learned
  • A lessons learned post after a launch or a feature release, with honest numbers
  • A question post asking the community for feedback on a decision you are stuck on
  • A transparent walkthrough of a tool you use, clearly labeled as paid, free, or affiliate-linked
  • A milestone post that shares the story behind the number instead of just the number

Avoid

  • Dropping a link with no context, story, or question attached
  • Writing a post that is only a promotion of your product
  • Sharing a tool or resource without saying whether it is paid, free, or affiliate-linked
  • Posting content that has nothing to do with building a project or learning a skill
  • Presenting someone else's work as your own
  • Sharing private or sensitive information about yourself or others without consent

What r/buildinpublic Is For

This is a community for creators, developers, entrepreneurs, and makers who share their journey as they build projects in public. People post about coding, designing, writing, and launching businesses. The shared thread is openness: you show your progress, your challenges, your wins, and your lessons. If you are building something and willing to talk honestly about how it is going, that is the room you are walking into.

Rules That Matter Before Posting

Four rules decide most outcomes here. “No Self-Promotion Without Context” says you can share your work, but not solely to promote it, and you should focus on progress, lessons learned, and asking for feedback. “Stay on Topic” means every post has to relate to building in public in some way. “No Spam” bans links, irrelevant content, and unsolicited advertisements, and promises immediate removal. “Transparency in Tools & Resources” requires you to say whether anything you share is paid, free, or affiliate-linked. “No Plagiarism or Misrepresentation” also matters if you share work, because it must be your own or properly credited.

What To Post

Post the journey, not the landing page. A good post here walks people through what you built this week, what broke, what you learned, and what you are unsure about. End with a real question so people can give feedback. If you mention a tool or link to something, say plainly whether it is paid, free, or an affiliate link, because the rules ask for that transparency and it builds trust. Sharing real numbers, real mistakes, and real decisions fits this community perfectly.

What To Avoid

Do not post a link with no story around it, because that trips “No Spam” and “No Self-Promotion Without Context” at the same time. Do not write a post that is just an advertisement in disguise. Do not go off topic with content that has nothing to do with building something. Do not share work that is not yours, and do not share private information about yourself or anyone else without consent. And treat people well, because “Be Respectful” is rule one for a reason.

Common questions about r/buildinpublic

Can I post about my own product here?

Yes, as long as the post is about your journey building it, with progress, lessons, or a request for feedback, and not solely a promotion.

Can I include a link to my site or tool?

Links are allowed with context, but you must be transparent about whether the thing you are linking to is paid, free, or affiliate-linked.

What happens if I post a plain advertisement?

The rules say spamming links or unsolicited advertisements leads to immediate removal.

Can I share someone else's work or a resource I found?

Only if it is properly credited and you have permission, since the rules require consent before sharing another person's work.

Do off-topic posts get removed?

Yes, the rules state that posts unrelated to building in public will be removed.
