## AIaC by Firefly

AIaC (Artificial Intelligence Infrastructure-as-Code) is an open-source command-line utility published by Firefly, the company behind cloud infrastructure management tooling. Its purpose is narrow and practical: remove the friction of writing infrastructure definitions by hand. You type a request such as a description of an S3 bucket with versioning and lifecycle rules, and AIaC asks a large language model to produce the corresponding Terraform, Pulumi, CloudFormation, Kubernetes or other supported template directly in your terminal, ready to be reviewed and committed.

The tool is distributed through GitHub under the gofireflyio organisation and installs as a single binary, so it fits naturally into scripts, CI pipelines and local development. It supports multiple model providers and lets you keep API keys in environment variables, which matters for teams that already have an approved LLM vendor. Because output is generated configuration rather than live infrastructure, AIaC acts as a fast first draft that a human engineer still validates before applying it.

AIaC is free to use and does not require an account on the project itself, although you pay your chosen AI provider for tokens. In practice it appeals to platform engineers, DevOps practitioners and developers who know what they want the cloud to look like but would rather describe it than hand-write every block of HCL or YAML.

**Pricing & Plans:** Free and open source. There is no cost for the AIaC CLI itself; you only pay your chosen LLM/API provider for the tokens used when generating templates.

- **Natural language to IaC:** Describe the infrastructure you want in ordinary English and receive a generated template in your chosen IaC dialect.
- **Multiple IaC targets:** Generates Terraform, Pulumi, CloudFormation, Kubernetes and other common infrastructure formats from the same prompt workflow.
- **Terminal-first CLI:** A single cross-platform binary that runs in your shell and can be scripted into CI/CD pipelines or pre-commit hooks.
- **Bring your own model:** Works with configurable LLM providers and API keys so teams can stay within their approved AI vendor.
- **Open source on GitHub:** Source code lives at gofireflyio/aiac, so you can inspect it, self-build it or contribute improvements.

**Strengths:** Genuinely free and open source with no account or subscription required; Reduces boilerplate time for engineers who already know the target architecture; Terminal-native, so it slots into existing scripts and pipelines without new tooling; Supports several IaC languages and model providers rather than locking you into one

**Limitations:** Generated templates still need careful human review before they touch real infrastructure; Requires your own LLM API key and familiarity with a command-line workflow; Best suited to experienced engineers; beginners may find raw CLI output harder to validate

## StackGen

StackGen is an agentic operations platform built for platform engineering, DevOps and SRE teams that are adopting AI-native development but still running unchanged operations processes. Its central idea is an "Autonomous Operations Factory": a set of purpose-built agents that turn intent into spec-driven delivery across the build, operate, observe and remediate phases of the software lifecycle.

The infrastructure side, branded Aiden for InfraOps, lets developers describe what they need inside the AI coding harness they already use, via MCP. StackGen then matches approved golden modules, checks the result against policy, and opens a pull request. A producer/consumer model lets platform teams define the guardrails while application developers self-serve safely, and continuous drift detection keeps deployed stacks aligned with declared state.

For operations, Aiden for SRE acts as an AI teammate that discovers services, builds topology, triages alerts using SLOs and error budgets, performs root cause analysis and runs pre-approved runbooks after operator review. Aiden for DevOps funnels tickets from ServiceNow, Jira and Linear into one inbox with tunable autonomy levels, while Aiden for Observability provides a managed Prometheus, Grafana and OpenTelemetry stack without per-host pricing. StackGen states that it integrates with the toolchain teams already own rather than replacing it.

**Pricing & Plans:** StackGen offers a freemium entry point with paid plans and enterprise pricing available on request. Specific tier pricing is quoted through the vendor's sales team, so check the website for current plan details.

- **Aiden for InfraOps:** Describe intent in your AI coding harness and get governed Terraform or OpenTofu back, built from your approved golden modules and policy-checked before it ships.
- **Aiden for SRE:** An AI SRE teammate that auto-discovers services, triages alerts by SLO and error budget, performs root cause analysis and executes pre-approved remediation with audit trails.
- **Aiden for DevOps:** Automates requests arriving from ServiceNow, Jira and Linear in a single operations inbox, triaged and matched to workflows with a visible decision trace and autonomy levels.
- **Aiden for Observability:** Managed open-standards observability with metrics, logs, traces and APM in one pane, native PromQL, drop-in Prometheus remote-write and no per-host pricing.
- **Cloud Discovery and Drift Remediation:** Scans cloud accounts to build topology and dependencies, converts existing infrastructure to modular code, and continuously detects and remediates drift.

**Strengths:** Covers infrastructure generation, incident response, ticket automation and observability in one agentic platform; Governance-first approach with policy checks, approved golden modules and full audit trails; Works through MCP inside existing AI coding harnesses such as Cursor and Claude Code; Managed observability avoids per-host pricing and cardinality surcharges
