Every Rayek plugin, one store. A custom plugin store for Decky Loader, holding my plugins for the Lenovo Legion Go and AYANEO handhelds, plus hardware-independent utilities. Add the address once and they install and update through Decky's own Store tab, like anything else.
Copy this address:
https://decky.rayek.workers.dev
On the device, open Decky → Settings → General → Store channel, switch it to Custom, and paste the address into the field that appears. The Store tab then lists the plugins below that have a public installation release.
Switching back to Default at any time restores the official store. Plugins already installed from here stay installed.
Legion Go 2 Companion brings TDP and CPU profiles, Fan Control with custom curves, battery protection, controller haptics, gyro, controller sleep, lighting, button remapping, controller firmware updates, an HDR brightness fix for games and Wi-Fi controls into one Steam overlay, with the same controls in a Desktop Mode app. It includes the features of LeGoTDP, LeGoVibeControl and the HDR fix from LeGo2BrightnessFix (SteamOS 3.9 handles the rest of the screen natively). Early beta on the Legion Go and Legion Go S.
Uninstall the overlapping standalone plugins before installing Companion: it pauses while they are installed and does not import their settings. See the migration instructions.
AYANEO 3 Companion brings the handheld's hardware controls into Decky Loader: TDP and CPU profiles, Fan Control with custom curves, vibration, lighting, rear-button bindings with TM Guard, Magic Modules, charge bypass, smart-amplifier audio and OLED display support, all from Game Mode.
DeckyVibranceHDR is saturation control under gamescope, in SDR and HDR alike. Which mapping applies is read from the panel's EDID rather than the model name, so it is not tied to one handheld.
DeckyEQ brings a live ten-band PipeWire equalizer to Gaming Mode, with a full-screen curve editor for touch and controller, bass, treble, stereo width and a volume boost of up to 12 dB kept from clipping by a limiter. Pick a built-in preset (including Legion Go S and Legion Go 2), save up to 64 of your own, give a game its own sound, and import or export sounds as JSON. Steam's volume and output stay untouched. Requires a working PipeWire audio session; no extra effects packages are needed on the tested SteamOS system.
SpotiDeck puts Spotify playback, playlists, albums, podcasts, search and your library in the Steam overlay, with separate music and game audio controls and a game/Spotify balance slider. Requires Spotify Premium and your own Spotify Web API Client ID; local playback also requires a Spotify Soloist API key.
FSR4 Injector brings AMD's official FSR 4.1 upscaler, with the Lite model made for handhelds, to games that already use FSR 3.1 on RDNA 3.5 handhelds (Radeon 890M) in SteamOS Gaming Mode. Turn it on per game from the Quick Access Menu; AMD's own library is downloaded from AMD and nothing is patched on disk.
DeckyLS brings Lossless Scaling frame generation to the game you are playing: one menu in the Quick Access Menu with Off / 2× – 8×, flow scale and performance mode, changed live without launch options. It installs the official, unmodified lsfg-vk 2.0 by PancakeTAS from its author's site and shows whether frame generation really runs. Requires Lossless Scaling bought on Steam and switched to its lsfg-vk branch.
DeckyReshade sets up ReShade for your Steam and non-Steam games from Gaming Mode and keeps it up to date: turn ReShade, AutoHDR or a RenoDX HDR mod on per game from the Quick Access Menu. ReShade, shaders and mods come straight from their authors, no launch options are needed, and every change can be undone.
There is no server. plugins.json is the entire store: Decky fetches it, parses it as a list
of plugins, and downloads each zip straight from its own GitHub release.
build_store.py regenerates the file. It reads plugin.json from each plugin repo on GitHub for the
name, author, description and tags, lists published stable releases, and hashes each new
published zip so Decky can verify what it downloaded. Every version already in the store stays: if one disappears
from GitHub, the script stops and leaves plugins.json as it is (to retire a version, delete it from
plugins.json by hand). Store artwork is kept in assets/ and plugin IDs stay stable. Draft and prerelease versions are excluded. The address never changes.
python build_store.py
git commit -am "Refresh the store" && git pushThe file is served by GitHub Pages from main, and worker.js fronts it at the address
above. A push takes a minute or so to appear.
The rebuild runs by itself every hour (.github/workflows/refresh-store.yml), so a new release reaches the store
within about an hour without any manual step. The hourly run commits only when a new version appeared; fresh
download counts are committed on the Monday run. Run it at any time from Actions → Refresh store → Run workflow
(that run also commits download counts).
Why a worker in front of GitHub Pages
The worker exists for one reason. Decky adds an X-Decky-Version header, which makes the
request non-simple, so the browser sends a OPTIONS preflight first and only issues the real
GET if the answer names that header. No static host answers it: GitHub Pages replies
405, raw.githubusercontent 403, and jsDelivr replies 200 but without
Access-Control-Allow-Headers, which the browser rejects just the same. A blocked request
leaves the store spinning forever rather than showing an error, because Store.tsx has no
catch around the fetch.
It also answers /versions, which Decky 3.3.1 calls to check installed plugins for updates: there it returns
{"Plugin name": ["newest version", "sha256"]} built from the same plugins.json, the shape the official store
uses. Without it Decky rejects the answer and never offers an update.
Sorting is the store's job too: the Store tab asks for ?sort_by=name|date|downloads&sort_direction=asc|desc,
and the worker sorts by the created and downloads fields build_store.py writes (date means the plugin's first
release, as in the official store). Download counts are as of the last run of build_store.py.
The worker reads whatever plugins.json currently says, so a plugin release never needs it redeployed; only a
change to worker.js itself does. node --test worker.test.mjs checks it against this repository's plugins.json.
What plugins.json has to get right
Three details, all handled by the generator:
artifactmust be present on every version. Without it Decky falls back to the official CDN, which does not have these plugins.hashis the SHA-256 of the zip and is verified after download; a mismatch refuses the install.namemust matchplugin.jsonexactly, because that is how Decky matches an installed plugin against a store entry when it checks for updates.
