Democratising Drone Engineering for India & the World. Physics-accurate, MAVLink-compatible, browser-native. No install. No hardware. Start for $1.
A single crash can cost ₹5,000–₹1,00,000. Testing in real air is brutally expensive for students and startups.
Dozens of flights, crashes, and repairs just to tune a drone. There had to be a better way.
Students in tier-2 cities locked out of real practice. No simulators, no hardware, no chance.
