Frequently Asked Questions

Are these tools really free?

Yes, all 169+ tools are completely free with no signup required. You can generate, validate, and download configuration files instantly.

How are the generated configs validated?

Every generator runs against official schemas and best-practice rulesets. Kubernetes YAML is validated against the K8s API schema, Terraform configs against HCL spec, and Dockerfiles against hadolint-style linting.

Can I use the generated configs in production?

Yes. All outputs are production-ready, following official documentation and community best practices. We always recommend reviewing and testing configs before deploying to production.

Do you support custom annotations and labels?

Absolutely. Every generator supports custom metadata, annotations, labels, and environment-specific overrides so you can tailor configs to your exact infrastructure.

How is ConfigGenerator different from writing configs by hand?

ConfigGenerator enforces schema validation, catches common mistakes (like missing resource limits or security contexts), and applies best practices automatically. What takes 30 minutes by hand is done in 30 seconds with validation built in.

Do you add new tools regularly?

Yes, we continuously expand the tool library based on community feedback and emerging DevOps practices. New generators and categories are added regularly.
