StackAI review

StackAI calls itself an enterprise AI agent factory, and it is aimed squarely at IT departments. Agents are built as agentic workflows that can read, write and execute tasks across 500+ enterprise integrations, with human review inserted at chosen decision points and a free choice of model for each task. The deployment options are the main reason to shortlist it: multi-tenant cloud, a virtual private cloud or on-premise, backed by feature controls, audit logs, SSO and compliance support listed as SOC 2, HIPAA and GDPR on the pricing page. Asana has acquired StackAI, which the vendor frames as bringing human and agent workflows into one place. The free plan gives 500 runs a month across 2 projects and 1 seat, and everything beyond that is a custom Enterprise quote. With no self-serve paid step, it scores lowest here on value and ease for teams outside large organizations.
