Tracking machine-learning experiments involves more than recording runs: artifacts, datasets, and models may also matter to a workflow. Compare API and SDK access, run comparison, artifact tracking, and dataset versioning to understand the listed areas each option addresses. A model registry or deployment options may be relevant depending on how you organize and use experiment outputs. Free-plan availability and paid-from pricing help round out the comparison. Weights & Biases, Comet, and DagsHub are among the options shown, alongside GitLab Package Registry. Consider which experiment details you need to keep connected, and weigh those needs against the capabilities and plan information provided for each tool.
31 ML experiment tracking software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
