Nativeblocks review
A focused open-source toolkit for testing and updating native mobile screens.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nativeblocks is an open-source server-driven UI and A/B testing platform for Android and iOS teams. Developers can define native screens with Kotlin, Swift, or TypeScript, then deploy frames through a CLI and deliver layout changes without a new app-store release. Its scope suits mobile teams that need experimentation, segmented rollouts, personalization, feature flags, and remote values alongside native screen delivery.
The pricing model starts with a free allowance: the first team member, first language, and first 100 monthly active users are included. The published paid add-ons show $9 per additional team member per month and $30 per additional language per month, billed monthly. Enterprise adds unlimited users, team members, languages, and usage, plus on-premise deployment, 24/7 dedicated support, and custom integrations. This structure fits teams that can keep their member and language requirements controlled, while larger deployments may need to assess the Enterprise option.
Nativeblocks stands out through its combination of frame-level A/B tests, multiple variants, percentage rollouts, rollback, audience targeting, typed remote values, caching, and offline frame caching. Native SDKs support Jetpack Compose and SwiftUI, while the visual editor, CLI DSL, and CLI-based release management give teams multiple ways to build and publish screens. Managed cloud hosting and self-hosted deployment options broaden its operating choices. It is a strong fit for native mobile teams centered on server-driven UI; teams seeking a broad, multi-platform experimentation system should consider a different category focus.
