I created Polar in 2019 to solve a problem I kept running into: setting up a local Lightning Network for development was painful. Hours of configuration, command-line wrestling, and frustration.
So I built a tool that does it in a few clicks.
What is Polar?
Polar is a free, open-source desktop app that lets you create local Bitcoin and Lightning Network environments for development and testing. No more config files. No more CLI headaches. Just a visual interface to spin up nodes, open channels, and test your Lightning apps.
Impact
- ⭐ 800+ GitHub stars
- 📥 30,000+ downloads
- 🌍 Translated into 10 languages
- 🛠️ Used by thousands of developers at companies building the future of Bitcoin payments
Why Sponsor?
I've kept Polar free and open-source for 5+ years because I believe great developer tools should be accessible to everyone. Your sponsorship helps me:
- Maintain compatibility with new Lightning/Bitcoin releases
- Fix bugs and respond to community issues
- Add new features requested by developers
- Keep the project alive for the long term
