Vectara
Vectara is an enterprise platform for retrieval-augmented AI agents with runtime policy enforcement and deployment choices (SaaS, VPC, on-prem). It focuses on governed generation, hallucination controls, and production features tailored for regulated industries and large-scale use.
The pricing page lists a 30-day free trial and three enterprise deployment tiers with annual starting prices: SaaS starting at $100K/year, VPC starting at $250K/year, and On-prem starting at $500K/year. Add-ons and premium support are available but require contact with sales.Is Vectara right for you?
Good for
- Companies that need governed, production-ready retrieval-augmented agents with always-on policy enforcement and flexible deployment (SaaS, VPC, or on-prem) for regulated environments.
- Supports multiple deployment models so you can choose SaaS, customer-managed VPC, or on-prem to match data control and compliance needs.
- Provides real-time policy and hallucination controls to enforce brand and compliance constraints at runtime.
Keep in mind
- Documented entry pricing is enterprise-grade with six-figure annual starting points for production deployments.
- The free option is a time-limited 30-day trial rather than a permanent free tier.
- Teams seeking a low-cost, self-serve starter product; documented production deployments start at six-figure annual pricing—confirm budget alignment and scope before procurement.
