I Built an AI-Powered vertical tab manager for Chrome that hit #2 on Product Hunt - Here's my solo dev journey from idea to 100+ paid users
I wanted to share my journey of building Side Space, an AI-powered Chrome extension that automatically organizes your tabs into meaningful groups. After one year of development, we just hit #2 Product of the Day on Product Hunt and crossed 3K active users and 100+ paid users!
The idea came from my own pain point - I'm that person with 50+ tabs open, desperately trying to find that one Stack Overflow post I saw earlier. I figured AI could solve this better than manual organization.
Some key learnings from the journey:
🔧 Technical Challenges:
-
Had zero experience with Chrome extensions (Stack Overflow became my best friend)
-
Implementing AI was trickier than expected - had to balance accuracy vs. processing speed
-
Learned that server costs for AI processing can add up quickly (Anthropic bills were scary at first)
👥 User Feedback Loop:
-
Released an early beta to 100 users from Twitter
-
Their feedback completely changed my initial feature roadmap
-
Found out users wanted simple grouping more than advanced AI features
💰 Marketing (with $0 budget):
-
Built in public on Twitter
-
Posted weekly progress on Reddit and Indie Hackers
-
The biggest surprise was how supportive the maker community has been. Every time I felt stuck, someone would jump in with advice or encouragement.
Current stats:
-
3k+ active users
-
4.3/5 rating on Chrome Web Store
-
#2 Product of day on Product Hunt
-
2.5K Revenue from premium features
Next steps:
-
Global Fuzzy Search (Most request feature)
-
Improving the AI model
-
Enhance the Space Management
Happy to answer any questions about the technical implementation, marketing strategies, or anything else! Also willing to jump on a call if anyone's building something similar and wants to chat.
Keep building awesome things! 🚀
