Instead of Biome
Biome alternatives
Biome serves web projects with formatting for JavaScript, TypeScript, JSX, TSX, JSON, HTML, CSS, and GraphQL, plus lint rules and safe fixes for several of those languages. Its check command can format, lint, and organize imports together, and its standalone executable runs without Node.js. It is free and supports editor extensions and CI integrations, making it a broad option for web-project maintenance.

goimports
Free plan LinuxMacWeb+1Go import maintenance and formatting — goimports adds missing Go imports, removes unused ones, and formats in gofmt style, unlike Biome's web-project checks.

Its focus is web projects, however, so teams working in Python, F#, Haskell, Go, or Android app accessibility may find a narrower tool a closer fit. The alternatives here are also free, but most center on formatting or a specific testing task rather than Biome’s combined checks. Compare the languages and tasks you need, then consider whether you prefer a fixed formatting style or configurable controls, and which editor, browser, or CI workflow matters. Switching may mean giving up Biome’s broader format-and-lint coverage in exchange for language-specific behavior or specialized checks.
