Stack AI review

4.4/5

No-code enterprise agent builder

Stack AI is a no-code, drag-and-drop platform for building enterprise AI agents and workflows that connect LLMs to internal data sources, documents, and apps. It leans hard on governance: on-prem/VPC deployment, SSO, access control, and SOC 2, HIPAA, and GDPR compliance. It targets regulated teams (finance, healthcare, legal) that need agents without writing code.

Best for Governed enterprise agents. Stack AI starts Free, then Custom (contact sales) on a Free tier plus custom enterprise quote (per-seat and usage based) model. Free gets you 500 runs/month on 1 seat; anything production is a custom enterprise quote, so real cost is whatever the sales team negotiates (third parties have estimated roughly $50 to $500 per user per month) plus your own LLM token usage.

The gotcha

the pricing catch

The live pricing page now shows only Free and Enterprise: there is no published paid mid-tier, so any real usage means a custom sales quote with no transparent price. On-prem/VPC, SSO, and compliance are all Enterprise-only.
