Pricing	freemium	freemium
Strengths	+ Drop-in proxy integration + Cost dashboards readable by non-engineers + Open source with managed option	+ Minimal instrumentation via the weave.op decorator + Evaluation framework for structured, comparative LLM assessments + Integrates with the broader Weights & Biases ML experiment platform + Apache-2.0 licensed client SDK
Tradeoffs	− Proxy adds a small latency hop (mitigated by async mode)	− Tied to a W&B account and backend rather than a standalone self-hosted store − TypeScript SDK is less mature than the Python SDK
