Why the models rank Prettier — on best code formatter
“Broadest native support for ubiquitous frontend, configuration, and documentation languages (JS/TS, JSON, YAML, Markdown, CSS, HTML, GraphQL) with an opinionated, zero-debate AST formatting engine and universal editor integration.”
Why the models rank treefmt — on best code formatter
“Near-tie with dprint for highly polyglot codebases because it takes the pragmatic approach of orchestrating each language's best native formatter behind one command, runs formatters in parallel, and can restrict work to changed files; particularly strong when a repo spans ecosystems such as Go, Rust, Python, Nix, C++, and TypeScript rather than mostly web languages.
