💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
Weave is a product layer within W&B focused on LLM application development. It uses the same W&B account, workspace, and infrastructure. Think of it as the LLM-specific interface built on top of W&B's core experiment tracking capabilities.
W&B is broader (covering traditional ML + LLM) while Langfuse and Braintrust are deeper on LLM-specific features. W&B excels at experiment comparison and team reporting. If you only do LLM work, dedicated tools are more streamlined. If you do both ML and LLM, W&B unifies everything.
Yes, through Weave's tracing and W&B's monitoring features. However, W&B's roots are in offline experiment tracking, so real-time production alerting is less mature than dedicated monitoring tools. Many teams use W&B for evaluation and a separate tool for production monitoring.
The free tier supports small teams with limited storage and compute. The Team plan starts around $50/user/month. For 10 engineers, expect $500-1,000/month depending on usage. Enterprise pricing is custom and includes SSO, audit logs, and dedicated support.
Compare features, test the interface, and see if it fits your workflow.
