Current state of sideloading

The stable Apple releases, imminent OS transition, and compatibility facts that are most likely to change.

Apple release status

As of this review:

  • iOS 26.6.2 is the latest listed public iOS 26 release.
  • iPadOS 26.7 is the latest listed public iPadOS 26 release.
  • iOS and iPadOS 27.0 RC were released to developers on 9 September 2026.
  • Apple says the version 27 operating systems will be available to customers soon; the RC is not yet the general public release.

The source of truth is Apple's live developer release feed. Version-sensitive tool claims should be rechecked after iOS 27 ships publicly.

Compatibility headlines

RouteCurrent position
App Store, TestFlight, XcodeNormal Apple-supported routes on current OS releases
Official alternative marketplacesAvailable in the EU, Japan, and Brazil, with regional differences
EU Web DistributionAvailable from iOS 17.5 and iPadOS 18 for approved developers
AltStore ClassicCurrent free/paid account signing; refresh model still applies
SideStoreCurrent; initial computer setup plus LocalDevVPN/pairing workflow
SideloadlyMaintainer claims iOS 7 through 26+; current release is 0.60.0
FeatherCurrent on-device certificate signer; installation mode and entitlements matter
TrollStoreCoreTrust range ends at iOS 17.0; 17.0.1 and later are unsupported
StikDebugSupports iOS 17.4 through 18.x; iOS 26+ support requires compatible app-side JIT behavior
LiveContainerSupports iOS/iPadOS 15+; guest-app limitations remain

Three warnings for the iOS 27 transition

  1. A tool launching on an RC does not prove that signing, installation, JIT, extensions, or every guest app works.
  2. Compatibility reports must include the full build number, device chip, signing method, and whether the app requires JIT.
  3. People preserving a TrollStore-compatible release must not update past its supported boundary. People on current public iOS should not expect TrollStore support.

Apple's iOS 27 release notes are still explicitly beta and RC-era documentation (Apple Developer).

What “supports iOS 26” can mean

The phrase may mean only that the signing tool opens, a basic app signs, installation succeeds, ordinary apps launch, or JIT works with a specific helper. Those are different claims.

For iOS 26 JIT, attaching a debugger is not always enough. Compatible apps may need an app-side executable-memory protocol. The StikJIT integration guide explicitly warns that selecting a generic script does not retrofit an arbitrary JIT engine.

Maintenance rule

Recheck this page after any public iOS/iPadOS release, major AltStore/SideStore/Feather/Sideloadly release, new CoreTrust disclosure, or change in Apple's regional alternative-distribution rules.
