dprint vs Taplo

dprint is a command-line application that automatically formats code through a configurable, pluggable system built with Rust and WebAssembly. Its official and wrapper plugins cover languages and formats including TypeScript, JavaScript, JSON, Markdown, TOML, CSS, Dockerfile, C#, Python, Go, Swift, GraphQL, YAML, PHP, LaTeX, R, and Julia. Project configuration files define plugins, formatting settings, included files, and exclusions. Plugins can be loaded from a URL or file path and pinned or versioned in configuration. The project says dprint formats hundreds of files in milliseconds and enables incremental caching by default. WebAssembly plugins run in a sandbox without network or file-system access, while process plugins are executable files and are not sandboxed. Editor integrations are listed for Visual Studio Code, IntelliJ, and Neovim; the language-server command can also be used by other editors. The CLI is distributed as a static binary with no runtime dependencies, with installation options including shell, PowerShell, Cargo, npm, and Homebrew. It is MIT-licensed and free.

Taplo is a free toolkit for validating, formatting, and querying TOML documents, with support for TOML 1.0.0. Its validator checks syntax and semantic issues such as duplicate keys, and can apply JSON Schema Draft 4 validation. The formatter can edit files in place or use standard input and output; by default, it stops when syntax errors occur to avoid destructive edits. The CLI also converts TOML to JSON and retrieves values through query expressions. Taplo’s language server communicates through standard input/output or TCP, though multiple TCP clients are not supported. It is excluded from default builds and is unavailable in the NPM installation. The Even Better TOML Visual Studio Code extension adds highlighting, validation, folding, navigation, renaming, formatting, and JSON Schema completion; its listing calls it a preview that may contain bugs or crash. Taplo can retrieve schemas from catalogs such as JSON Schema Store and match them to files by name. Install options include precompiled releases, Cargo, Homebrew, NPM, and Docker; precompiled releases are listed for Linux, macOS, and Windows.
