Agentic Index
Galileo vs Langfuse (2026)
Choose Galileo for managed evaluation with its own low latency Luna judge models and built in guardrailing, and choose Langfuse for open source tracing and observability you control end to end. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Galileo starts at 100 dollars a month billed yearly with a free tier, while Langfuse runs free on Hobby, 29 dollars a month on Core, and self hosts free under MIT. Galileo is now owned by Cisco, and its documentation says it became Splunk Agent Observability on 7 August 2026, while galileo.ai still sells the Galileo plans quoted here. Galileo sells opinionated, vendor maintained metrics; Langfuse sells an open platform you instrument and extend yourself.
On the Agentic Index agent infrastructure ranking, Galileo and Langfuse both clear the bar: each documents all five production contract capabilities in full. 34 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 Langfuse 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 956 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Galileo if
- Prebuilt, research grade evaluation metrics out of the box beat building your own
- Inline guardrailing with low latency judge models is part of the requirement
- You want failure mode detection and root cause analysis done for you
Choose Langfuse if
- Open source self hosting and data control outrank managed convenience
- Your evals are custom anyway, so you want the tracing substrate, not the judges
- The 29 dollars a month unlimited user plan fits your budget reality

Galileo is owned by Cisco. Its documentation says it became Splunk Agent Observability on 7 August 2026 and points customers who joined after that date to Splunk's documentation; galileo.ai still sells the Galileo plans quoted on this page. Langfuse was acquired by ClickHouse in January 2026 and continues as an open source, self hostable platform under the MIT license. Buyers outside the ClickHouse ecosystem should weigh roadmap priorities accordingly.
