Best LLM & Agent Infrastructure for enterprise teams
Last verified:
Crail tracks 10 LLM & Agent Infrastructure vendors that list enterprise teams as a fit. These are the 5 that rank highest once the list is weighted for enterprise teams, and each one is shown with compliance evidence, deployment control and data residency — the facts that decide the shortlist at this size, rather than the same summary on every page.
How this list is weighted for enterprise teams
- 60% of the vendor's Crail agent-readiness score
- up to 24 points for published compliance certifications (8 per certification)
- 10 points for documented SSO/SAML support
- 6 points for a documented audit log
Startups and small businesses share the price-and-self-serve weighting; midmarket and enterprise share the compliance weighting. The full rules are on the methodology page.

FAQ
How is this LLM & Agent Infrastructure ranking calculated for enterprise teams?
This is not the raw agent-readiness leaderboard. Crail scores the 10 LLM & Agent Infrastructure vendors it tracks that fit enterprise teams, using 60% of the vendor's Crail agent-readiness score; up to 24 points for published compliance certifications (8 per certification); 10 points for documented SSO/SAML support; 6 points for a documented audit log. Arize Phoenix ranks first once the enterprise teams weighting is applied, even though Braintrust scores higher on raw agent-readiness (88/100 against Arize Phoenix's 86/100), because the weighting adds points that score does not cover.
Which of these can run inside our own cloud or data center?
Arize Phoenix (cloud, self-hosted, hybrid, on-prem, BYOC), Langfuse (cloud, self-hosted, hybrid, on-prem), Weights & Biases Weave (cloud, self-hosted, on-prem), Portkey (cloud, self-hosted, hybrid, on-prem) and Braintrust (cloud, self-hosted, hybrid, BYOC, on-prem) document deployment outside the vendor's own cloud. Data-residency options are published by Arize Phoenix (Customer-controlled (self-hosted/on-prem)), Langfuse (US, EU, Japan), Portkey (Custom (Enterprise VPC / air-gapped)) and Braintrust (US, EU).
What compliance certifications do these vendors publish?
Arize Phoenix: SOC 2 Type II, ISO/IEC 27001, PCI DSS, HIPAA, GDPR. Langfuse: SOC 2 Type II, ISO 27001, GDPR, HIPAA (BAA available). Weights & Biases Weave: SOC 2 Type II, HIPAA. Portkey: SOC 2 Type II, ISO 27001, GDPR, HIPAA. Braintrust: SOC 2 Type II, HIPAA.
