A config format for humans SOML is short for Sindre's Objectively Marvelous Language.
SOML is a config format that is pleasant to write and easy to read. The top level needs no braces, keys need no quotes, line breaks replace commas, and comments go almost anywhere. A value's type comes from its syntax, never from its content, so what you see is what you get: '123' is a string and 123 is an int. Dates like 2026-09-19, instants like 2026-09-19T14:00:00Z, and durations like 30s are real values, so nobody has to guess the unit of timeout: 30. Paths and regexes need no escaping, and prose goes in block strings. One canonical form and a shared conformance suite mean every implementation reads your file the same way. JSON has the strictness but not the comfort: quotes, commas, and braces everywhere, and no comments. YAML has the comfort but not the clarity: - list markers, nested indentation, and types guessed from content, so country: no becomes false and version: 3.10 becomes 3.1. SOML gives you the comfort and the strictness, without the guessing.
