Reviewer scorecard
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
