Formatting tools help teams apply consistent code style across languages and projects. Compared on supported languages and platforms, editor integration, and changed-lines formatting, the entries show different ways formatting can fit a development workflow. Ignore files and a library API may matter for what gets formatted and how the tool connects with other software. License model, free-plan availability, and paid-from pricing add further points to consider. gofmt, Prettier, and Taplo are among the tools to weigh against your editors, codebase, and preferred setup.
