Web Compatibility
PowerSync’s web-targeting SDKs use either IndexedDB or OPFS 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.| VFS | Chrome | Chrome incognito | Firefox | Firefox incognito | Safari | Safari incognito | iOS Webkit | Android Chrome |

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. 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 if an enterprise customer requires it.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 / the project’s pubspec.yaml.
-
Android: Several of our SDKs require AndroidX 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 higherminSdk.
