Weights & Biases
wandb.ai
ML experiment tracking platform — log metrics, compare runs, visualize model performance, and collaborate on machine learning projects.
Why it is useful
W&B makes it trivially easy to track every training run, compare hyperparameter experiments side by side, and share results with teammates. A few lines of code is all it takes to integrate. The free tier covers most individual and academic use cases without any limits on logged data.
