Galileo vs W&B Weave (2026)
Both evaluate and guardrail agents in production, and Galileo's distinguishing bet is its own evaluation models.
Galileo runs Luna, low latency models purpose built for scoring, so evaluation happens fast enough to sit in the request path, from 100 dollars a month billed yearly with a free tier. Weave scores with LLM as a judge plus safety scorers inside the Weights and Biases platform, free then about 60 dollars a month plus usage. If evaluation has to run inline rather than after the fact, that is the whole argument for Galileo.
Choose Galileo if
- Evaluation latency is a design constraint because scoring runs in the request path, not in a batch job.
- You want purpose built evaluation models rather than a general model asked to judge.
- Guardrails and evaluation from one vendor is the shape you want.
Choose W&B Weave if
- Weights and Biases is already your platform and consolidation is worth more than inline speed.
- A lower entry price without an annual billing commitment fits how you want to start.
- Session aware tracing across long running agents is the specific capability you need.
