The Great JavaScript Toolchain Rewrite: Why Biome and Oxlint Are Replacing ESLint

JavaScript teams face a critical inflection point as performance bottlenecks in ESLint—taking 30-60 seconds on moderate codebases—drive adoption of Rust-powered alternatives that deliver 50-100x speedups. The choice between Biome's all-in-one consolidation (unified configuration, no custom plugin support) and Oxlint's ESLint-compatibility-first approach (existing plugins, separate formatter) determines whether you unlock truly frictionless linting workflows or merely optimize the wrong bottleneck. This decision reshapes not just tooling speed, but how teams architect their development processes.
