Common Flairs

Who's Here

Developers, designers, and indie makers who build products outside their day jobs. Most have tried launching something before. They appreciate technical details and honest metrics.

Common Mistakes on r/SideProject

Avoid these pitfalls that get marketers banned or ignored.

Posting just an idea without any execution

r/SideProject values shipped products. "I have an idea for X" posts get ignored because there's nothing to evaluate or discuss.

Instead

Build an MVP first, even if it's rough. A working prototype gets 10x more engagement than a polished pitch deck.

Not including a working demo link

The community wants to try things. Posts without links feel like ads rather than genuine project shares.

Instead

Always include a live URL. If it's not ready, share a video walkthrough or screenshots showing actual functionality.

Being vague about the tech stack

This is a developer-heavy community. They want to know how you built it, not just what you built.

Instead

Include your stack in the post: "Built with Next.js, Supabase, and deployed on Vercel." It starts good technical discussions.

Ignoring feedback in the comments

People take time to test your project and give feedback. Not responding makes you look like you only wanted exposure.

Instead

Reply to every comment within 24 hours. Acknowledge bug reports. Thank people for suggestions, even if you won't implement them.

Overloading with features in the description

Long feature lists are hard to parse. The community wants to understand your core value proposition quickly.

Instead

Lead with one clear problem you solve. "I built X because Y was frustrating me." Features can go in a comment.

Post Formats That Work on r/SideProject

These content formats consistently perform well in this community.

Launch Post

Example Format

""I built [product] to solve [specific problem]. Here's the demo: [link]. Stack: [tech]. Looking for feedback on [specific area].""

Why It Works

Clear structure. Demo link upfront. Tech stack for credibility. Specific feedback request encourages engagement.

Progress Update

Example Format

""Month 3 update on [project]: hit [milestone], learned [insight], next up is [goal]. Current metrics: [numbers].""

Why It Works

Shows momentum without overselling. Real numbers build trust. The journey is as interesting as the destination.

Technical Deep-Dive

Example Format

""How I built [feature] for my side project using [tech]. Here's what worked, what didn't, and what I'd do differently.""

Why It Works

Educational content gets saved and shared. Provides value beyond self-promotion. Establishes expertise.

Frequently Asked Questions

Common questions about marketing on r/SideProject

Yes, r/SideProject is one of the most promotion-friendly subreddits for makers. The key difference: you need a working product, not just an idea. Include a demo link, be transparent about what stage you're at, and engage genuinely with feedback.
Weekend mornings (Saturday/Sunday 9am-12pm EST) see the highest engagement since many members work on side projects during free time. Weekday evenings (6-9pm EST) also work well when developers are unwinding from their day jobs.
Ask specific questions, not generic "what do you think?" requests. "Does the onboarding flow make sense?" or "Which pricing tier would you choose?" gets more actionable responses than "any feedback welcome."
Revenue transparency performs extremely well on r/SideProject. Posts with real metrics ("$500 MRR after 6 months") get significantly more engagement than vague success claims. The community values honesty about the journey, including the struggles.
r/SideProject is more casual and developer-focused. It's for products built "on the side" without venture funding expectations. r/startups skews toward funded companies and growth-stage discussions. r/SideProject is more welcoming to MVPs and experiments.
Yes, but space them out and add new value each time. Progress updates ("hit 100 users"), major feature launches, or post-mortems all work well. Avoid posting the same launch announcement repeatedly.
