Agentic Index
Galileo vs W&B Weave (2026)
Both vendors last verified
Both evaluate and guardrail agents in production, and Galileo's distinguishing bet is its own evaluation models. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Galileo runs Luna, low latency models purpose built for scoring, so evaluation happens fast enough to sit in the request path, with a free tier and paid plans from $100 a month on yearly billing. Weave scores with LLM as a judge plus safety scorers inside the Weights and Biases platform, free, then $60 a month plus usage on Pro. If evaluation has to run inline rather than after the fact, that is the whole argument for Galileo.
On the Agentic Index agent infrastructure ranking, Galileo and W&B Weave both clear the bar: each documents all five production contract capabilities in full. 33 of the 186 vendors in the lane clear it. See the agent infrastructure ranking
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Galileo and W&B Weave are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 1,084 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
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 matters 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.

GalileoIntegrations & Tool Calling Tracing integrations cover A2A, CrewAI, Google ADK, LangChain and LangGraph, Mastra, Microsoft Agent Framework, the OpenAI SDKs, Pydantic AI, Strands and the Vercel AI SDK, and Galileo connects model providers for its metrics. These bring telemetry in. There are no connectors that let an agent take authenticated actions in outside systems.

W&B WeaveIntegrations & Tool Calling Integrations with LLM providers, agent SDKs and harnesses such as the OpenAI Agents SDK, Claude Agent SDK and Google ADK, and frameworks such as LangChain, CrewAI and LlamaIndex let Weave trace calls, and it traces activity between MCP clients and servers, while alerts go out by Slack and email. These bring trace data in and send notifications out, and none connects an agent to a real system to take actions.
