Parses, validates, and reformats config files. TOML, INI, HCL, Caddyfile, and Nginx use the formatter tab (Nginx also lints for common errors); Docker Compose and GitHub Actions use the linter tab (GitHub Actions also has a form-based workflow builder); .htaccess and Helm inspect/generate from options. For TOML ↔ YAML conversion, see YAML Tools' dedicated tab.

Frequently asked questions

How do I convert a docker-compose file to Kubernetes manifests?

Use the Compose → Kubernetes tab. Paste your compose file and it generates Kubernetes manifests, which you should review before deploying.

How do I lint a GitHub Actions workflow?

Open the GitHub Actions tab and use Lint to check the workflow YAML. A Build mode lets you assemble a workflow visually.

How do I check an nginx config for mistakes?

The Nginx tab formats the config and lints it, for example for missing semicolons. It is a static check and does not replace running nginx -t.

Can I find hardcoded secrets in a Helm values.yaml?

Yes, the Helm tab flattens values.yaml into a table and warns when a key with a secret-like name (such as password or apiKey) holds a literal value, plus null or empty values.

Can I view a Terraform state file?

Yes, the Terraform State tab lists resources from state or terraform show -json output. A separate HCL tab formats .tf files.

Is my data uploaded to a server?

No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
