Experiment tracking tools such as Neptune’s enable data science teams to monitor AI model training runs, compare results across different configurations, and identify issues during the development process. Neptune’s platform tracked metrics including loss curves, gradient statistics, and activation patterns across thousands of concurrent experiments.
Following Neptune’s withdrawal from the market, users of its SaaS version have a few months’ grace to export their data and migrate to alternative platforms during which the company will continue to provide stability and security fixes, but will add no new features, it said. “On March 4, 2026, at 10 am PST: The hosted app and API will be turned off. Any remaining hosted data will be securely and irreversibly deleted as part of the shutdown,” Neptune said on its transition hub web page.
Self-hosted customers will have been contacted by their account manager, it said.
