From the Jain perspective, no—Gosala was not a follower of Jain ahimsa and aparigraha as Jain vows. Jainism treats ahimsa and aparigraha as core vows on the path to liberation, but Makkhali Gosala is remembered as the founder of the Ajivika tradition, which emphasized niyati (fate/determinism) rather than the Jain idea that disciplined vows and effort lead to spiritual progress.

That said, some descriptions of the Ajivikas say they practiced rigorous asceticism and even non-violence, but they did not hold that moral effort, vows, or renunciation could change destiny in the Jain way. So the closest accurate answer is: he may have valued ascetic restraint, but not Jain ahimsa and aparigraha as spiritually effective Jain vows. ( philopedia.org)
