Braintrust vs Lambda Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Braintrust has a free plan. Lambda doesn't — you'll need to pay from day one.

How do they charge?

Different approach here. Braintrust uses hybrid pricing, while Lambda goes with usage-based. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Braintrust: At $249/mo flat for Pro, Braintrust sits mid-to-premium compared to open-source or DIY logging stacks, but it undercuts the fully custom enterprise observability players by keeping a transparent starting price public. They're clearly courting AI-native teams who've outgrown free tools but aren't ready for an enterprise sales cycle yet. Lambda: Lambda positions as a serious alternative to hyperscalers (AWS, GCP, Azure) for ML teams who want raw GPU access without cloud markup or complexity. They're not the cheapest bare-metal option, but the no-egress-fees policy and 1-Click Clusters are a direct shot at teams burned by AWS networking costs.
