The short version
- Each has a real cost: Galileo the free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.; Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity
- They diverge on capability: Galileo covers Pre-built evaluations, Perplexity covers Real-time web search.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Galileo
- The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
- Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
- Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
- On-premises deployment requires an Enterprise contract rather than being available self-serve.
Perplexity
- Context window has been stealthily reduced despite prior claims of 1-million-token capacity
- Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
- Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
- Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
- Pro subscription quotas and feature access quietly reduced without user notification

Questions people ask
- Is Galileo or Perplexity better?
- Neither clearly leads. Galileo starts at Free and Perplexity at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Galileo or Perplexity?
- Galileo starts at Free and Perplexity at Free.
- Does Galileo or Perplexity run on more platforms?
- Galileo runs on web, api. Perplexity runs on Web, iOS, Android, Comet (AI browser).
- Can I use Galileo for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Galileo best used for?
- Galileo is most often used for evaluating rag and agent applications before production release, monitoring live genai applications for failures and drift, applying real-time guardrails without custom integration work, reducing evaluation costs using distilled luna judge models. Of those, evaluating rag and agent applications before production release and monitoring live genai applications for failures and drift are not what Perplexity is typically brought in for.
- What can Galileo do that Perplexity cannot?
- Galileo covers Pre-built evaluations, Ground truth capture, Luna models, Agent behavior analysis. Perplexity covers Real-time web search, Source citations, Follow-up questions, File analysis.
Answered from the vendors’ own pages
Galileo: What does Galileo cost?
Galileo offers a free plan, a Pro plan at $100/month billed yearly (with a 33% annual discount), and a custom-priced Enterprise plan for unlimited trace capacity.
SourcePerplexity: Is Perplexity completely free?
Perplexity has a free tier with unlimited basic searches and 3 Pro Searches per day. Pro ($20/month or $200/year) and Max ($200/month) tiers unlock more advanced features like multi-model access and unrestricted queries.
SourceGalileo: Is there a free plan, and what are its limits?
The Free plan includes 5,000 traces per month with unlimited users and unlimited custom evaluations, aimed at developers and small teams experimenting with GenAI.
SourcePerplexity: What is the difference between Pro and Max?
Pro provides access to advanced AI models like GPT-5.2, Claude Sonnet 4.5, and Gemini 3 Pro. Max adds Labs for multi-agent orchestration, Perplexity Computer with 19 specialized AI sub-agents, and 10,000 Computer credits per month.
SourceGalileo: How is usage metered?
Galileo's pricing scales based on the number of traces processed each month, with Free capped at 5,000, Pro at 50,000, and Enterprise offering unlimited trace capacity.
SourcePerplexity: Can I use Perplexity offline?
No. Perplexity requires an active internet connection for all searches. The full answer service is not available offline.
SourcePerplexity: What platforms does Perplexity support?
Perplexity is available as a web application, iOS app, Android app, and as Comet, a dedicated AI browser for mobile (Android available, iOS in development).
SourcePerplexity: How reliable are Perplexity's citations?
Citations are a key feature of Perplexity, but users report that citations sometimes point to irrelevant or overly general articles that don't directly support the claims made.
SourcePerplexity: Does Perplexity's context window match the advertised 1 million tokens?
Perplexity had promoted a 1-million-token context window, but users have reported stealth reductions in the actual context capacity without public announcement.
