View Full Features →Stack AI maintains SOC 2 Type II, HIPAA, GDPR, and ISO 27001 certifications with AES-256 encryption at rest and in transit. They use dedicated infrastructure through Azure OpenAI and AWS Bedrock, offer on-premise and VPC deployment options, and provide explicit guarantees that customer data is never used for AI model training. Enterprise clients receive Business Associate Agreements (BAA) for healthcare use cases and Data Processing Agreements (DPA) with all AI providers.
While Flowise and Langflow offer greater technical customization at zero platform cost, Stack AI provides managed infrastructure, enterprise compliance certifications, professional support, and a more polished user interface. Stack AI targets enterprise buyers who need compliance and support, while open-source alternatives serve developers comfortable managing their own infrastructure and requiring maximum customization.
