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.
Or install via pip: pip install "git+https://github.com/HARSHALJETHWA19/TellIaC.git#subdirectory=hiac&egg=hiac[all]"
Everything Terraform does — plus Plain English, HCL Export, Cost Estimation & Security Rules.
Write infrastructure as sentences. Deterministic grammar parser translates natural English into concrete cloud resources offline.
One file. Provision AWS, Azure, GCP, and Kubernetes resources simultaneously in a single telliac apply command.
Encapsulate infrastructure into blueprints (Include module "vpc_stack" named "prod_net") with zero-collision namespacing.
Export `.hiac` configs into standard Terraform HCL files (main.tf, variables.tf, outputs.tf) for Terraform Cloud & OpenTofu.
Calculate resource-level and total monthly cloud spend (telliac cost) before applying changes.
CLI state management (telliac backend status/init/migrate) supporting local, S3, Azure Blob, and GCS with distributed locking.
Export Mermaid.js diagrams, terminal ASCII trees, or standalone interactive HTML visualizers with telliac graph.
Scan for security vulnerabilities (telliac lint) and auto-align assignment formatting (telliac fmt).
Generate full valid `.hiac` configuration files directly from plain English prompt descriptions (telliac generate).
Browse supported infrastructure resources filtered by Cloud Provider.
Edit plain English code below and click any TellIaC tool command to see real-time simulated CLI execution!
From zero to multi-cloud infrastructure in 4 commands.
