Key Features
- Session replay at scale: Watch real user journeys across devices to see context behind metrics and reproduce issues quickly
- Events funnels and cohorts: Quantify behaviors drop offs and retention to prioritize fixes and opportunities
- Heatmaps and page analytics: Visualize clicks scroll depth and engagement to guide layout and content decisions
- Rage click and error detection: Surface frustration patterns API slowdowns and console errors for engineering triage
- Segmentation and filters: Slice by device version campaign locale or feature flags to see who is affected and how
- Integrations to team tools: Send clips and events to Jira Slack GA and BI so insights reach owners immediately
- Experiment tracking: Log metrics and hyperparameters to compare runs and reproduce results across machines and teammates
- Artifacts and datasets: Version artifacts and datasets so training inputs and outputs remain traceable over time
- Collaboration workspace: Share dashboards and reports so teams align on model performance and release decisions
- System integration: Integrate logging into training code so observability is automatic not a manual reporting step
- Cloud or self hosted: Official pricing describes cloud hosted plans and self hosting for infrastructure control needs
- Governance at scale: Paid plans support org needs like security controls and larger team workflows
Use Cases
- Debug hard to reproduce issues by watching sessions with console logs to speed fixes
- Prioritize roadmap using funnels cohorts and replay to see actual friction points
- Improve onboarding by testing layouts and measuring drop off in first run experiences
- Guide design changes with heatmaps and page analytics that show what users try to do
- Support agents attach replays to tickets to reduce back and forth and improve CSAT
- Product managers validate hypotheses by pairing metrics with real context before committing sprints
- Training visibility: Track experiments across models and datasets to find what improved accuracy and what caused regressions
- Hyperparameter search: Compare sweeps and runs to identify stable settings without losing configuration context
- Artifact lineage: Trace a model back to the dataset and code version used for training and evaluation evidence
- Team reporting: Publish dashboards for leadership that summarize progress and quality metrics over a release cycle
- Production debugging: Compare production failures with training runs to isolate data shift and pipeline differences
- Self hosted governance: Deploy self hosted W&B when policy requires tighter control of data access and storage
