How is W&B different from TensorBoard?

If you’re evaluating experiment tracking tools or migrating from TensorBoard, this page summarizes the key differences to help you decide whether W&B fits your workflow.

W&B integrates with TensorBoard and extends what experiment tracking tools can do. The founders created W&B to address common frustrations that TensorBoard users face. Key improvements include:

• Model reproducibility: W&B supports experimentation, exploration, and model reproduction. It captures metrics, hyperparameters, and code versions, and it saves model checkpoints to ensure reproducibility.
• Automatic organization: W&B simplifies project handoffs and vacations by providing an overview of all attempted models, which saves time by preventing you from re-running old experiments.
• Quick integration: Integrate W&B into your project in five minutes. Install the free open source Python package and add a few lines of code. Logged metrics and records appear with each model run.
• Centralized dashboard: Access a consistent dashboard regardless of where training occurs (locally, on lab clusters, or cloud spot instances). You don’t need to manage TensorBoard files across different machines.
• Filtering table: Search, filter, sort, and group results from your models. Identify the best-performing models for different tasks, an area where TensorBoard often struggles with larger projects.
• Collaboration tools: W&B supports collaboration on complex machine learning projects. Share project links and use private teams to share results. Create reports with interactive visualizations and Markdown descriptions for work logs or presentations.
