dragonpilot

Founded in 2019, dragonpilot is a long-running openpilot fork built around a "minimal changes" philosophy, staying close to stock openpilot while adding carefully chosen features like ALKA, vehicle-specific tuning, and continued comma 3 support. It is primarily backed by a Chinese-speaking community and remains non-commercial with no Patreon or paid tiers.
