Support matrix

Where RubyEverywhere runs today, and where it is headed. Both tracks, Do It Yourself and the Platform, build the same app, so this applies to both.

Operating systems#

macOS, iOS, and Android all ship today: one everywhere.yml stamps the desktop shell and both mobile shells. Windows and Linux are next.

Mobile is remote mode only. The iOS and Android shells wrap your deployed app. Pressing a Ruby runtime into the binary is a desktop capability.

Platforms and architectures#

Desktop builds target Apple Silicon today; desktop x86_64 arrives alongside Windows and Linux. The Android shell is pure Kotlin with no native libraries, so one APK covers both ABIs.

Store requirements#

Both stores raise their floor on a schedule, and a build that misses it is rejected at upload. The shell templates track the current requirement rather than the oldest version that still compiles.

You do not set these yourself. They live in the frozen shell templates and move when RubyEverywhere moves, so upgrading the gem is what picks them up. The one exception is platforms.android.target_sdk, for getting ahead of a Play deadline.

Ruby versions#

Your app's Ruby runtime is pressed into the binary by rbe-tebako. These are the versions RubyEverywhere builds against:

Pin yours with build.ruby in everywhere.yml. A version that is not listed here has not been validated for pressing, so stick to a supported release if you want reproducible builds.

Frameworks#

RubyEverywhere packages Rails, Hanami, and Sinatra apps. Each framework page covers its specifics:

• Rails, the primary and best-tested path
• Hanami
• Sinatra
