Code formatting tools help maintain consistent source code across projects, languages, and development setups. Compared on supported languages and platforms, editor integration, and changed-lines formatting, the entries can be assessed against how you work with code. Ignore-file support and a library API offer additional workflow considerations, while license model, free-plan availability, and paid-from pricing help clarify access and cost. Accessibility Test Framework for Android, rustfmt, and Black are among the tools to compare for fit with your coding environment. Consider where formatting needs to happen, which languages you use, and how you want the tool to connect with the rest of your workflow.
