This Is How We Vibe
We build in public - sharing ideas, wins, and lessons as we go.
We learn from each other, with feedback that helps us get better.
StartSnap.fun is a place to connect, share your progress, or just see what others are up to.
Why Build in Public?
- Show your process. Every step counts, even the rough ones.
- Get real feedback. Honest thoughts help you improve.
- Meet others. Builders, mentors, and friends are here too.
- Inspire someone. Your story might help someone else start.
How We Support You
- Vibe Log: Share updates - big or small, as they happen.
- Community Feedback: Get advice and ideas from others.
- Project Support: See who's cheering you on.
- Opportunities: Let people know if you're open to new things.
