Reviewer scorecard
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
