Reviewer scorecard
“One tool replacing Prettier + ESLint with massively better performance. The migration from existing configs is smooth.”
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“The speed improvement is not a micro-optimization — it changes CI feedback loops and editor responsiveness.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“Rust-based tooling replacing JavaScript tools is the trend. Biome is the most impactful example.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
