FAQ
What is TOML, and why should I use it?
TOML (Tom's Obvious, Minimal Language) is a human-readable configuration format. It's the default for Python (pyproject.toml), Rust (Cargo.toml), and Go modules. If you work across multiple language ecosystems, TOML is the lingua franca of configuration — more readable than JSON, less ambiguous than YAML.
Where does my data go when I use these tools?
Nowhere. Every tool processes data exclusively in your browser using JavaScript. No data is uploaded to any server, logged, or analyzed. Open the Network tab in DevTools — you'll see zero outbound requests after the initial page load.
What TOML specification version is supported?
All tools conform to TOML v1.0.0. Supported: bare/quoted/dotted keys, basic/literal/multiline strings, all integer and float formats, booleans, offset/local date-times, dates, times, arrays, tables, inline tables, and arrays of tables.
