    Live research

    Fresh domain knowledge pulled from the web.

    Tracked topics

    • RN New Architecture rollout 2026

      Fabric + TurboModules stable across mainstream libs; migration is 4–8 engineer-weeks for mid-size apps.

    • OTA update policy risk

      Apple guideline 4.7 enforcement tighter; static-shell + server-driven UI is the safer pattern.

    • Flutter vs RN adoption

      RN wins where teams already write TS/React; Flutter wins on greenfield brand experiences.
