treefmt is a CLI tool that unifies running multiple code formatters across a polyglot repository with a single command. It runs formatters in parallel, tracks file changes to only reformat modified files, and is configured via a treefmt.toml file.

Use cases

• format all files in a multi-language repo with one command
• replace per-project formatter shell scripts
• run code formatters in parallel for speed
• only reformat files that changed since last run
• standardize formatter output across a team
• integrate formatting into CI pipelines

When to choose

• your repository mixes many languages each with its own formatter
• you want a single unified CLI and config for all formatters
• formatting speed matters and you want parallel, incremental runs

When to avoid

• you only use a single language with one formatter
• you need a formatter itself rather than a multiplexer of existing ones
• your formatters are not supported or configurable via treefmt.toml
