Assessed attributes for Galileo, each with the source it came from and the date it was checked
Licence proprietary (SaaS) — Galileo Cloud is a hosted product with no published open-source server; the vendor's own Python client SDK for it (github.com/rungalileo/galileo-python) is Apache-2.0 Source, checked
Self-host partial: self-hosting (VPC or on-prem) is offered only on the Enterprise tier, arranged via sales; Free and Pro are Galileo Cloud only Source, checked
OpenTelemetry yes — a dedicated OTLP trace endpoint (https://api.galileo.ai/otel/traces on Galileo Cloud, an equivalent api-* URL on self-hosted deployments) plus a GalileoSpanProcessor for the OpenTelemetry Python SDK Source, checked
Free tier limits Free plan at $0/month: 5,000 traces per month, unlimited users, unlimited custom evals; no retention figure stated Source, checked
Price per 100k traces not published for 100,000 traces — the top published self-serve tier is Pro at $100/month for 50,000 traces per month, and that $100 is shown under a "Billed yearly" control with "Save (33%)" (the page shows no month-to-month figure); volumes above 50,000 fall to Enterprise "Contact us". Linear extrapolation would give $200/month, but the vendor states only that pricing scales with trace volume. Currency USD. Source, checked
Data residency United States — the vendor's privacy policy states Personal Data is transferred to Galileo's facilities and servers in the United States; no published EU or other region choice on Galileo Cloud (VPC/on-prem on the Enterprise tier is the only stated alternative location) Source, checked
Retention unstated Source, checked
SDK languages Python and TypeScript official SDKs, plus a REST API Source, checked

Assessment

Galileo Cloud is a proprietary hosted product with no published open-source server; the vendor's Python client SDK is Apache-2.0. Self-hosting in a VPC or on premises is Enterprise-only, arranged through sales; Free and Pro are cloud-only.

OpenTelemetry ingestion has a dedicated OTLP trace endpoint, separate from the regular API endpoint, plus a span processor for the OTel Python SDK. Official SDKs are Python and TypeScript alongside a REST API.

The Free plan is $0 with 5,000 traces a month, unlimited users and custom evaluations. The top self-serve tier is Pro at $100 a month for 50,000 traces, and that $100 sits under a "Billed yearly" control, with no month-to-month figure on the page. Volumes above 50,000 fall to an Enterprise "Contact us", so no price for 100,000 traces is published; the vendor says only that pricing scales with trace volume.

Retention is unstated: the word appears nowhere in the docs index, pricing page or trust-and-security page. The privacy policy does place data in the United States, stating Personal Data is transferred to Galileo's facilities and servers there.

The most recent feature-bearing release-notes entry is dated 4 August 2026; the 7 August entry carries no product change, announcing the Splunk Agent Observability rebrand, and the docs banner states the site applies to customers who onboarded before that date.
