How to Build in Public on Social Media: A Practical Guide

Building in public, sharing your product's progress, challenges, and milestones publicly, is one of the most effective growth strategies for indie hackers and SaaS founders. It builds trust, attracts early users, and creates a community around your product before you even launch.

But it can easily eat your day if you don't have a system.

The 5-minute building-in-public workflow

1. Write one update (2 minutes): What you shipped, what you learned, or what you're working on next
2. Select platforms (10 seconds): X, Threads, Bluesky, Mastodon, LinkedIn. Pick all that apply
3. Schedule or publish (30 seconds): Post immediately or schedule for your audience's peak time
4. Engage with responses (2 minutes): Reply to comments and questions once they come in

Total: 5 minutes. Shaflex handles the cross-posting automatically.

What to share

Weekly rotation:

Day	Content Type	Example
Monday	What I'm working on this week	"This week: shipping the new analytics dashboard"
Tuesday	Technical decision or learning	"Why we chose X over Y for our auth system"
Wednesday	Metrics or milestone	"Hit 100 signups this week. Here's what worked:"
Thursday	Behind-the-scenes	Screenshot of your workspace, code, or design
Friday	Wins and learnings	"This week's biggest win: [thing]. Biggest learning: [thing]"

Where to post

X/Twitter: The default platform for building in public. Threads work well for longer updates.

Bluesky: Growing developer community. Less noise than X. Your posts get more organic reach.

Mastodon: Strong open-source and developer community. Especially good for technical products.

LinkedIn: Professional audience. Great for B2B SaaS and career-related building-in-public content.

Threads: Broader audience. Good for reaching people outside the developer bubble.

Tips for consistency

• Batch-create content on Sunday evening for the week ahead
• Schedule posts at consistent times so your audience knows when to expect updates. Our guide on mastering social media scheduling can help
• Use threads for milestone posts or technical deep-dives
• Cross-post everything: your X audience is different from your Bluesky audience
• Don't overthink it: a quick update is better than a polished post you never publish
