Reviewer scorecard
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
