neckbeard is a plugin for coding agents that turns an application into reviewable cloud infrastructure and a monthly cost estimate. It supports AWS, GCP, or Azure, with GitHub Actions or GitLab CI, and serverless containers or Kubernetes. Infrastructure is rendered from a bundled catalog of tested OpenTofu modules. The agent reads your app and explains the results, while planning, rendering, and validation are handled by deterministic code. The agent never invents infrastructure.
Installation requires two prompts in Claude Code: adding the marketplace and installing the plugin. Running /neckbeard:analyze in your app's repository then installs a small CLI, using a sha256-verified release binary or go install when Go is present. Cost estimates and static validation rely on tools such as Infracost, OpenTofu, and Checkov, and /neckbeard:doctor reports which are missing and what each unlocks.
The workflow has four steps. /neckbeard:analyze produces an evidence-backed profile of the app and asks the questions code cannot answer. /neckbeard:estimate plans against the catalog and shows a $77/mo expected cost, with a table and a list of resources Infracost cannot price. /neckbeard:sync scaffolds and validates the infrastructure, reporting a V0 PASSED status. Users then review the files like any pull request and follow the runbook for each environment.
The project's stated goal is to address the usual failure mode of agent-written infrastructure: plausible but subtly broken, insecure, and unestimable configuration code. Its cost reporting is explicit about baseline costs, usage assumptions, and unpriced resources, and it can compare options such as serverless versus Kubernetes for a reference app.
