StackGen

StackGen generates production-ready Terraform, K8s manifests, and policies from application context.

StackGen's Aiden agentic workflows take application context (services, dependencies, target cloud) rather than raw prompts and emit complete Terraform modules with VPC, subnets, security groups, RDS, ECS, and IAM roles correctly wired together. Outputs include Kubernetes deployment manifests and matching OPA policies aligned with organizational patterns, not generic boilerplate.

Who it's for. Platform teams of 10 to 30 engineers building internal developer platforms that need golden-path provisioning without hand-coding every module for every service shape. Scenario: a developer describes a microservice needing an API endpoint, a DynamoDB table, and an SQS queue, and StackGen generates the Terraform, the K8s deployment, and the encryption-at-rest OPA policy in one pass, all consistent with the organization's existing patterns.

Tradeoffs. No free tier; Essentials and Growth tiers have unpublished prices. Output quality is solid for common patterns and gets shakier on novel architectures, requiring manual refinement. The agentic workflows need write access to cloud accounts, which demands careful IAM scoping.
