Pricing at a glance

↻ Billing notes

Comet’s official public pricing is a mix of free and paid cloud access. The Free Cloud plan is presented as a free tier, Pro Cloud is shown at $19 per month, and Enterprise is custom with contact-sales pricing. The site says you do not need a credit card to sign up and that the account comes with a free tier you can use for as long as you like, but it does not publicly disclose annual billing discounts or seat-based minimums for the paid cloud plan. The pricing page does show usage overages for spans and retention, and the third-party listing for Basic says a Free Trial and Free Version are available.

Hidden and indirect costs

Worth budgeting for
⚠  The official pricing page shows usage-based overages for spans and span retention, which means the effective monthly bill can rise above the base Pro Cloud fee if teams exceed included limits or need longer retention. The page also states that some capabilities, including Opik Connect and cloud access for certain workflows, are on a free-trial-then-purchase-tokens basis, so buyers should expect potentially variable consumption costs depending on how they use the platform.
⚠  Enterprise pricing is custom, so procurement, security review, and deployment requirements may materially affect final cost. The page also indicates that flexible deployments, compliance features, service accounts, view-only users, and dedicated SLAs are bundled into Enterprise rather than sold as separate public line items, making the true total depend on negotiation rather than list pricing.
