About TOML

TOML is a minimal configuration format with clear key = value pairs and [sections]. It powers Cargo.toml, pyproject.toml, Hugo and many other tool configs.

About YAML

YAML is an indentation-based format used for Kubernetes manifests, Docker Compose, GitHub Actions, OpenAPI specs and countless config files. It is a superset of JSON that favours readability.

Private by design

Developer data is often sensitive: API responses, tokens, customer records, internal configs. This TOML to YAML processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
