Paid plans start at $19/mo. There's also a free plan.
Comet starts at $19 per month for Pro Cloud, according to its pricing page; Free Cloud and self-hosted Open Source are listed at $0. Free Cloud is capped at 10 members and 25,000 spans monthly, while Pro allows 50 members and 100,000 spans. Extra Pro spans cost $5 per 100,000. Annual pricing, Ollie token prices, and the optional MLOps add-on price are not published. Enterprise pricing is custom, so the listed $19 may not cover every use case.

Annual billing

03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Teams self-hosting Opik | Open Source | It costs $0 per month and includes AI observability, agent testing, tracing, test suites, and the Agent Playground. |
| Individuals and small teams | Free Cloud | It costs $0 per month and includes up to 10 members, 25,000 spans monthly, and 60-day data retention. |
| Teams needing more usage | Pro Cloud | It costs $19 per month and raises the limits to 50 members and 100,000 monthly spans; extra spans cost $5 per 100,000. |
04Is Comet worth the money?
Comet may justify $19 per month for teams that need more than basic LLM logging: the feature set includes tracing, tests and evaluations, production monitoring, and training-run comparisons. But the price is only a clean comparison point if 100,000 spans monthly and 60-day retention fit your workload. Overages add $5 per 100,000 spans, while Ollie tokens and the MLOps add-on have unpublished prices. We can’t call it cheaper than alternatives without comparable pricing.
Comet pricing FAQ
Does Comet browser free?
If you mean Comet.com’s developer platform, its pricing page lists Free Cloud at $0 per month and Open Source at $0 for teams self-hosting Opik. The published pricing details do not establish whether a Comet browser is free; browser pricing is not published here.
Is Perplexity free for students?
The published Comet pricing information does not list Perplexity student pricing or discounts. It covers Comet’s AI evaluation, observability, and MLOps plans. For student eligibility or current Perplexity offers, check Perplexity’s own pricing or education information.
Is Comet better than Chrome?
This page covers Comet’s developer tools for LLM observability and MLOps, not a browser comparison. The published information does not compare Comet with Chrome on features, performance, or price, so it cannot establish which is better for your needs.
Is Comet safe Perplexity?
The pricing information does not describe browser security or confirm product details about a Comet browser. It covers Comet’s developer platform, including Opik and MLOps tools. We can’t assess safety or privacy from plan prices; check the relevant product’s security and privacy documentation.
