Choose Galileo if low-latency guardrails scoring 100% of production traffic are your core requirement and you are already in an enterprise procurement process.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-text-align-left has-background-color has-text-color has-link-color has-body-m-font-size wp-elements-2 wp-block-paragraph\">Both tools trace, evaluate, and monitor LLM and agent applications in production. Opik is an open-source LLM observability and agent evaluation platform built by Comet. Galileo is a proprietary evaluation and agent-reliability platform, acquired by Cisco in May 2026. The practical difference is where your data lives and what it costs to grow: Opik is Apache-2.0 with a free, full-feature self-host, while Galileo reserves VPC and on-premises deployment for its Enterprise tier. Galileo\u2019s Luna-2 small language models are an advantage for scoring every production request cheaply. Opik covers the same lifecycle under a licence you can read, run, and modify yourself.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull has-custom-alt-background-dark-background-color has-background is-layout-constrained wp-container-core-group-is-layout-e5a791a7 wp-block-group-is-layout-constrained\" style=\"border-top-color:var(--wp--preset--color--custom-decorative-border-dark);border-top-width:1px;border-bottom-color:var(--wp--preset--color--custom-decorative-border-dark);border-bottom-width:1px;margin-top:var(--wp--preset--spacing--100);margin-bottom:var(--wp--preset--spacing--100);padding-top:var(--wp--preset--spacing--100);padding-bottom:var(--wp--preset--spacing--100)\">\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">What are the best alternatives to Galileo in 2026?<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">The platforms teams evaluate most often against Galileo are Opik, Langfuse, Arize Phoenix, and Weights &amp; Biases Weave. Listed with public GitHub footprint as of 2026-08-19, which is a reasonable proxy for how many teams have inspected and run the code themselves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Opik<\/strong>, 21,487 stars. Apache-2.0, free full-feature self-host, framework-neutral, 75 documented integrations.<\/li>\n\n\n\n<li><strong>Langfuse<\/strong>, 33,396 stars. Strong tracing and prompt management, open source.<\/li>\n\n\n\n<li><strong>Arize Phoenix<\/strong>, 11,114 stars. Open source, with roots in model and drift monitoring.<\/li>\n\n\n\n<li><strong>Weights &amp; Biases Weave<\/strong>, 1,119 stars. The Weave library is Apache-2.0; running the platform yourself goes through W&amp;B Server as a self-managed or Dedicated Cloud deployment, with an enterprise licence for the security and enterprise capabilities.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Galileo itself has no open-source distribution, so it does not appear on that list. If your requirement is running entirely inside your own infrastructure without an enterprise agreement, the shortlist starts with Opik and Langfuse. If you need real-time guardrails backed by purpose-built evaluation models and have the enterprise budget for it, Galileo is a reasonable choice. We keep&nbsp;<a href=\"about:blank\">comparisons against each of these tools<\/a>&nbsp;if you want the head-to-head detail.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">What is the difference between Galileo and Opik?<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">The divergence is ownership and optimization. Opik\u2019s full feature set runs on your own hardware under a licence you can read, and it ships autonomous prompt optimization as part of the product. Opik\u2019s Test Suites simplify evaluation workflows, allowing the user to define plain-text assertions and view pass-fail results, rather than creating datasets and choosing individual LLM-as-a-judge evaluation metrics. Opik\u2019s Diagnostics feature actively surfaces recurring issues across many traces, recommending fixes. Diagnostics is available in the free cloud version of Opik but not in the OSS version. Galileo\u2019s most differentiated capabilities \u2014 Luna-2 evaluation models, Luna Studio for fine-tuning your own, real-time protection, SSO, and VPC or on-premises deployment \u2014 are gated behind the Enterprise tier and a sales conversation.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-text-align-left\">How do Galileo and Opik compare, feature by feature?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">They match on more than the category noise suggests. Both trace, evaluate offline and online, annotate with human reviewers, evaluate multimodal content, and enforce runtime guardrails. Opik is Apache-2.0 with free full-feature self-hosting, integrates with 75 documented frameworks and providers, and ships autonomous prompt optimization. Galileo is proprietary, gates deployment and real-time protection behind Enterprise, and ships purpose-built evaluation models that Opik does not have an equivalent for.<\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">Rows are marked from each vendor\u2019s own public documentation as of August 2026.

Opik\u2019s guardrails documentation states the feature is currently available in the self-hosted installation, with managed deployment support coming. Galileo\u2019s Protect module was deprecated in June 2026 and replaced by Agent Control; running metric checks in real time there requires Luna-2 on the Enterprise tier, or writing custom code-based metrics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prompt optimization is the row most often reported wrong. Galileo does document prompt work: Playgrounds, Experiments, and Autotune, which turns human feedback into prompt improvements for LLM-as-a-Judge metrics. What its documentation does not describe is autonomously searching prompt variants against a fitness function, which is what Opik\u2019s Agent Optimizer does across six algorithms. The difference is autonomy, and it is about the agent\u2019s prompts rather than the evaluator\u2019s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Opik has no answer to Luna-2.<\/strong>&nbsp;Galileo distils its evaluator suite into compact models that score production traffic without a frontier-model call. Opik runs LLM-as-a-Judge and heuristic metrics instead. For teams scoring every request at high volume, that is a genuine architectural difference.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull has-custom-alt-background-dark-background-color has-background is-layout-constrained wp-container-core-group-is-layout-e5a791a7 wp-block-group-is-layout-constrained\" style=\"border-top-color:var(--wp--preset--color--custom-decorative-border-dark);border-top-width:1px;border-bottom-color:var(--wp--preset--color--custom-decorative-border-dark);border-bottom-width:1px;margin-top:var(--wp--preset--spacing--100);margin-bottom:var(--wp--preset--spacing--100);padding-top:var(--wp--preset--spacing--100);padding-bottom:var(--wp--preset--spacing--100)\">\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">Can you self-host Galileo or Opik?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Both, on very different terms, and this is the clearest difference between them. Opik is Apache-2.0 and self-hosts free with the full feature set, so your traces never leave your infrastructure and there is no licence conversation. Self-hosting is a single command against the&nbsp;<code>opik.sh<\/code>&nbsp;script, or a Helm chart for Kubernetes. The open-source tier carries unlimited spans, unlimited team members, and unlimited retention at $0.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Galileo offers Hosted, VPC, and on-premises deployment, but only on the Enterprise plan and through sales. There is no open-source distribution to inspect or run independently, and Luna Studio, the surface for training your own evaluation models, is described in Galileo\u2019s documentation as part of the enterprise tier and deployed by Galileo into your cluster or cloud. For a team that needs data residency before it needs an enterprise contract, that is the deciding difference.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">Is Opik a good open-source alternative to Galileo?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and specifically for teams whose reason for looking is data control, cost at the entry tier, or framework independence. Opik covers the same core jobs \u2014 tracing, offline and online evaluation, annotation, guardrails, and production monitoring \u2014 under an open licence you can inspect and run yourself, at $19 per month for the entry paid tier against Galileo\u2019s $100.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off is real and worth naming. If your requirement is scoring 100% of production traffic in real time at low latency and low cost, Galileo\u2019s Luna-2 models are purpose-built for exactly that and Opik has no equivalent. Teams whose reliability problem is a volume problem should evaluate both.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">Which has better evaluation?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">They are closer than either vendor\u2019s marketing suggests, and they are strong in different places.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Galileo\u2019s advantage is evaluation economics in production. Luna-2 is a family of small language models distilled for evaluation, and Galileo reports sub-200ms latency at roughly $0.02 per million tokens, which is what makes scoring every request affordable rather than sampling. Luna Studio lets Enterprise teams fine-tune their own metric models against labelled data. Its agentic metric set is well specified, with 10 documented metrics covering action advancement and completion, agent efficiency and flow, reasoning coherence, and tool selection and error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Opik\u2019s advantage is lifecycle breadth and closing the loop. It evaluates agent trajectories, multi-turn conversations, and threads, supports multimodal evaluation, and ships Annotation Queues with claim-and-lock so two reviewers do not grade the same trace. The clearest gap is Opik\u2019s Test Suites, which greatly simplify evaluation workflows, automating the creation of datasets and metrics behind the scenes based on users\u2019 plain-text assertions. Your agent runs and passes or fails against each assertion, rather than returning floating point numerical scores against many metrics, making this workflow easier to use and more actionable for debugging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your evaluation problem is cost per scored request, Galileo. If it is finding the better prompt and shipping the fix, Opik.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-text-align-left\">How do Galileo and Opik pricing compare?<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">Opik\u2019s free cloud tier is $0 for 25k spans per month with up to 10 team members and 60-day retention, and Pro Cloud is $19 per month flat for 100k spans and up to 50 members.

Units differ: Opik meters spans and Galileo meters traces, and a single trace contains multiple spans, so the free tiers are not directly comparable on volume. Seats differ in Galileo\u2019s favour on the free tier: unlimited users against Opik\u2019s 10. The comparisons that hold cleanly are the entry paid price, $19 per month against $100 per month, and self-hosting, which is free and unlimited on Opik and Enterprise-only on Galileo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Galileo pricing captured from galileo.ai\/pricing on 2026-08-19.

Opik is free and open source, so there is no trial window at all: self-host the full product with no account and no credit card, or start on the $0 cloud tier with 25k spans per month. Galileo offers a free tier at 5,000 traces per month with unlimited users and unlimited custom evals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The caveat for a Galileo proof of concept is that the capabilities most likely to drive the decision \u2014 Luna-2, real-time guardrails, SSO, and VPC or on-premises deployment \u2014 are Enterprise-gated, so the free tier cannot demonstrate them. If Luna-2 economics are why you are evaluating Galileo, ask for a scoped Enterprise trial rather than judging from the free tier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a genuine proof of concept, instrument one production agent in both for two weeks and compare what each surfaced. Traces are cheap to duplicate and the result is usually decisive.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\">How do you get started with Opik?<\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">About five minutes and three steps. Most teams find something they can fix within their agent in the first hour.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Install the SDK: <code>pip install opik<\/code><\/li>\n\n\n\n<li>Add the <code>@track<\/code> decorator, or enable the integration for your framework.<\/li>\n\n\n\n<li>Open the trace view and read your last 100 production calls.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Self-hosting is a single command against the <code>opik.sh<\/code> script, or a Helm chart for Kubernetes. The self-host guide covers both.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are scoring retrieval quality rather than agent behavior, the RAG evaluation guide covers the metrics underneath ContextRecall and ContextPrecision.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\"><strong><strong>Where does Galileo beat Opik?<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">Three places, honestly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Luna-2 and evaluation economics at scale. Compact evaluation models that score production traffic without a frontier-model call are a genuine architectural advantage, and Opik has no equivalent. Galileo reports sub-200ms latency and roughly $0.02 per million tokens, which changes what you can afford to score. Luna Studio extends this to fine-tuning your own metric models on labelled data, which no open-source competitor currently matches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Multimodal evaluation depth. Both platforms evaluate multimodal content, and Galileo\u2019s documented metric set is more specific: Visual Quality, Visual Fidelity for brand-rule compliance in generated images, and Interruption Detection for turn-taking violations in voice agents. Teams building voice or image-generation agents should look at both closely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Enterprise procurement path. Galileo is now part of Cisco, with its technology folding into Splunk Observability Cloud\u2019s AI Agent Monitoring. For an organisation that already buys Cisco and Splunk, a single vendor, a single contract, and one support relationship is a legitimate preference rather than a compromise.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-left has-display-s-font-size\"><strong><strong>Which should you choose?<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Choose Opik if you need self-hosting without an enterprise contract, want your trace data to stay in your own environment, build across more than one agent framework, want autonomous prompt optimization built into the product, want to read and modify the evaluation code you depend on, or want an entry paid tier at $19 rather than $100 per month.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Choose Galileo if you<\/strong>&nbsp;need to score 100% of production traffic in real time at low latency and low cost, want to fine-tune your own evaluation models, are building voice or image-generation agents that need specialised multimodal metrics, are already in an enterprise procurement process with a VPC or on-premises requirement, or already buy Cisco and Splunk.<\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">One factor worth weighing on a multi-year decision. Cisco announced its intent to acquire Galileo on 2026-04-09 and completed the acquisition on 2026-05-22, stating that Galileo\u2019s technology will extend Splunk Observability Cloud\u2019s AI Agent Monitoring. The roadmap for Galileo as a standalone product has not been detailed publicly. That is not a reason to rule it out, and it is a question worth asking in the sales conversation.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignwide is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-center\"><strong><strong><strong>Frequently asked questions<\/strong><\/strong><\/strong><\/h2>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\" style=\"margin-top:var(--wp--preset--spacing--100);margin-bottom:var(--wp--preset--spacing--100)\">\n<div class=\"wp-block-comet-accordion-accordion comet-accordion\" data-allow-multiple=\"true\">\n<details class=\"wp-block-comet-accordion-item comet-accordion__item\" open><summary class=\"comet-accordion__item-summary\"><h3><strong>Is Opik really free, or is it open core?<\/strong><\/h3><span class=\"comet-accordion__item-icon\" aria-hidden=\"true\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"16\" height=\"16\" fill=\"none\" stroke=\"#191A1C\"><path stroke-linecap=\"round\" stroke-linejoin=\"round\" stroke-width=\"2\" d=\"M8 1v14m7-7H1\"><\/path><\/svg><\/span><\/summary><div class=\"comet-accordion__item-content\">\n<p class=\"wp-block-paragraph\">Apache-2.0, and the self-hosted build is the full product rather than a feature-limited community edition.
