Biome review
An open-source web toolchain combining linting, formatting, fixes, and editor support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Biome is an open-source toolchain for web projects, combining a formatter, linter, command-line interface, and Language Server Protocol integration. It is aimed at developers and teams maintaining modern web applications, with support for static analysis, formatting, import organization, configurable lint rules, code fixes, and CI-oriented checks. The published language-support table lists 17 entries across web-focused formats and related languages.
There is no paid tier to compare: Biome is open source and can run on Windows, macOS, Linux, or in a self-hosted environment. Teams can adopt it through npm, pnpm, Bun, Deno, or Yarn, or use official Docker images and standalone binaries. Its ecosystem coverage includes first-party integrations for VS Code, IntelliJ, and Zed, plus GitHub Actions and GitLab CI. The biome ci command is designed for CI-optimized checking, while safe and unsafe fixes support different levels of automated code changes.
Biome’s breadth is its main distinction within a web-code linting workflow. Alongside standard diagnostics, it includes import sorting, rule groups with configurable severities and options, security rules, and custom lint diagnostics through GritQL plugins. That makes it a strong fit for teams seeking one toolchain across formatting, linting, editor support, and continuous integration. Teams should look closely at language-specific coverage before adopting it broadly: the published list includes experimental and in-progress languages, and not every listed entry currently supports linting. For web-focused teams, Biome offers a wide open-source workflow; projects outside that focus may prefer a tool aligned with their language set.
