TellIaC — Human Infrastructure as Code Platform

Tell your cloud
what to build.

TellIaC is an all-in-one IaC engine where infrastructure is described in plain English — no YAML, no DSL, no special syntax. Provision across AWS, Azure, GCP, and Kubernetes, export to native Terraform HCL, estimate cloud spend, scan security vulnerabilities, and generate architecture graphs.

~/my-project
