Skyline (formerly MonoNX and Lightswitch) is a free compatibility layer for the Nintendo Switch that runs on Android and is written in C++ and Kotlin.
Unlike the sketchy Egg NS, Skyline can run on more phones that support Android 10 or newer with a 64-bit processor and is not limited to flagship devices.
Even though the Skyline team has done good work getting a variety of 3D games, including Super Mario Odyssey, to run with graphical output and fixing performance issues and bugs in games, some other titles are still stuck with poor framerates and graphical glitches.
Skyline reached ingame on two Nintendo Switch games in January 2022 and has been improving massively since then.
Skyline was founded as "Lightswitch" in June 2019 by daCyuubi.
In May 2021, Skyline booted up several homebrew tests with graphical output.
Later, in January 2022, Sonic Mania and Celeste started booting, albeit with low FPS and graphical glitches.
March 2022 saw the improvement of Celeste in terms of graphics, along with the emulator rendering the openings of Super Mario Odyssey, the menu of The Legend of Zelda: Breath of the Wild, and Bastion booting ingame.
In April 2022, more improvements to performance were made, making Super Mario Odyssey run roughly 10x faster in its openings  and getting Unity games running.
In May 2022, Super Mario Odyssey was able to show 3D rendering, however really slow and with many graphical bugs, (TBA)
In October 2022, the developers released Skyline Edge, a paid testing version that you could get by joining the "Edge" membership on their Patreon page. They also released other memberships including Edge+, which gives you development polls, and Pro XDR, where your Patreon name could be in the credits of the app.
On May 6, 2023, a Skyline developer posted this via the Skyline Discord server:
"It is with great sadness that we bring you this news. Recently, Nintendo has issued a DMCA takedown notice against Lockpick RCM which will likely come into effect on Monday, Lockpick is a core part of legally dumping keys from the Switch. They claim that it circumvents their copy protection (TPMs) and therefore violates their copyright. We find ourselves in a position where we are potentially violating their copyright by continuing to develop our project, Skyline, by dumping keys from our own Switches."
The Strato fork continues to be actively developed.
