If your app needs to keep data on mobile devices and synchronize changes, database choices can affect both development and day-to-day behavior. Compared on offline mode, data synchronization, and conflict resolution, these entries also cover mobile platforms and SDK languages. Monthly sync limits, free plans, and paid-from prices help clarify capacity and cost. Ditto, Firestore, and ObjectBox are among the first entries, followed by RxDB and Drift; Couchbase Lite, Isar, and Parse Platform also appear near the start. Use the listed criteria to assess fit with your target platforms and development stack, and how you want local and synchronized data handled.
26 mobile databases ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
