FPVtune is a free, web-based automatic PID tuning tool for FPV drones. Every FPV pilot knows the pain of manual PID tuning — hours of test flights, analyzing blackbox logs, tweaking values, and repeating the cycle. FPVtune eliminates this tedious process entirely.

Simply upload your Betaflight blackbox log file, and FPVtune analyzes your gyro data to identify noise patterns, oscillations, and filter performance. Within minutes, you get optimized PID and filter settings tailored to your specific quad setup.

Works with all types of FPV builds including freestyle quads, racing drones, cinewhoops, and tiny whoops. Compatible with Betaflight and INAV flight controllers. Fix oscillations, reduce propwash, and achieve a locked-in feel without being a tuning expert.

FPVtune is open source and completely free to use. No installation required — everything runs in your browser at fpvtune.com.
