Best Code Formatting Tools in 2026
Updated
In short: Accessibility Test Framework for Android is ranked #1 of 34 as of 4 October 2026, ahead of swift-format and Black. The best-ranked option with a free plan is Black.
Choosing a formatter starts with the languages and platforms used in your development environment. dprint and Prettier open the ranking, with clang-format among the first entries. Compare supported languages and platforms with editor integration, changed-lines formatting, and ignore-file support. A library API may matter for integrating formatting into other software; license model, free-plan availability, and paid-from pricing are also listed for comparison. The 30 entries are ranked as a best-of selection, giving you technical and access details to weigh against your coding workflow.
34 code formatting tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
