trackio

Trackio is a lightweight, local-first, and free experiment tracking library built by Hugging Face. It offers an API compatible with Weights & Biases (wandb) for seamless migration, allowing users to log metrics, parameters, and artifacts. Logs are persisted locally in an SQLite database and can be optionally synced with Hugging Face Datasets and visualized on Hugging Face Spaces. It is actively developed with a focus on simplicity, extensibility, and LLM-friendly programmatic access.
