# Supported Platforms
> Supported platforms and feature availability for each PowerSync Client SDK across mobile, web, and desktop.
## Widespread SDK Platform Support
The versions below are the minimum supported versions across all PowerSync Client SDKs, so you can expect them to work regardless of which SDK you use.
| Platform | Version |

| Android | SDK 24 (Android 7.0) |
| iOS | 15.0 |
| macOS | 14.0 (Sonoma) |

Note that some client SDKs may support lower versions than the ones listed here.
## Supported SDK Platforms
> Note: An empty `Platform Version` cell means that the lowest target version is currently unknown/untested.
### Dart/Flutter
| Platform / Feature | Supported? | Platform Version | Notes |
| --------------------------- | -------------------------------------------- | ---------------------------------------------------------------------------------------------- | -------------------------------------------- |
| Android | Yes (x86-64, aarch64, armv7) | SDK 24 (Android 7.0) | Requires Flutter |
| iOS | Yes | 13.0 | Requires Flutter |
| macOS | Yes (x86-64, aarch64) | 12.0 (Monterey) | |
| Windows | Yes (x86-64, x86, aarch64) | 10 | |
| Linux | Yes (x86-64, x86, aarch64, armv7, riscv64gc) | Requires glibc 2.34+ | |
| Web | Yes | OPFS by default, IndexedDB as backup ([see more](/client-sdks/frameworks/flutter-web-support)) | Only dart2js is tested, dart2wasm has issues |
| HTTP connection method | Yes | – | |
| WebSocket connection method | No | – | |
### React Native
| Platform / Feature | Supported? | Platform Version | Notes |
| --------------------------- | ----------------- | -------------------------------------------- | ------- |
| React Native | Yes | RN 0.72 | |
| React Native w/ Expo | Yes | RN 0.72, Expo 49† | |
| React Native for Web | Yes | See [Web Compatibility](#web-compatibility). | |

† Expo 49 requires expo-build-properties `minSdkVersion` >= 24 and Metro `sourceExts` to contain `'mjs'`. Expo 50-51 require expo-build-properties `minSdkVersion` >= 24. Expo 52+ sets `minSdkVersion` and `sourceExts` correctly.
### JavaScript
| Platform / Feature | Supported? | Notes |
| --------------------------- | ---------- | ---------------------------------- |
| Chrome & Chrome-based | Yes | See VFS notes |
| Firefox | Yes | OPFS Not supported in private tabs |
| Safari | Yes | OPFS Not supported in private tabs |
| HTTP connection method | Yes | |
| WebSocket connection method | Yes | |
#### Web Compatibility
PowerSync's web-targeting SDKs use either an [IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API) or [OPFS](https://developer.mozilla.org/en-US/docs/Web/API/File_System_API/Origin_private_file_system)-based virtual filesystem (VFS) to persist rows on the user's device. On Dart/Flutter, the VFS is chosen automatically; on JS, the developer can choose which VFS strategy they prefer. Each VFS enjoys differing levels of platform support across browsers / devices / operating systems.
For a full list of VFS implementations, comparisons, and caveats, see [SQLite Virtual File Systems](/client-sdks/reference/javascript-web#sqlite-virtual-file-systems).

## Supported Platforms Policy
PowerSync supports a wide number of target platforms across its many SDKs. We aim to support as many platforms and versions as are useful for users and practical to maintain.
### When we raise the minimum version
In general, PowerSync aims to support any platform version that still receives security updates from the platform provider. For platforms that follow an LTS and Current release model, this means we aim to support all active LTS releases along with the Current release.
Supporting every version that fits the above criteria is [not always feasible](#exceptions). When we cannot support all of them, we prioritise support for newer versions over older versions to ease maintenance. We will occasionally maintain support for an older version on a case-by-case basis for larger customers. Reach out to us at `hello@powersync.com` if this is you.
### Exceptions
* **Dart/Flutter**: The Dart/Flutter team only supports the latest stable release (three-month cycle). We don't follow this release schedule, since dropping support for versions only three months old is undesirable. For the Dart/Flutter SDK's minimum Dart SDK version, see [pub.dev](https://pub.dev/packages/powersync/versions) / the project's [pubspec.yaml](https://github.com/powersync-ja/powersync.dart/blob/main/pubspec.yaml#L6).
* **Android**: Several of our SDKs require [AndroidX](https://developer.android.com/jetpack/androidx/versions) libraries. We set our minimum to the current AndroidX default `minSdk` (which AndroidX picks to cover \~99% of Play Store users), except in cases where other factors force a higher `minSdk`.
