RGB lighting is a mess. Single-vendor tools that don't talk to each other, half-working daemons, and effects that look like they were designed in 2012. The one great effects engine is proprietary, Windows-only, and behind a subscription.
Hypercolor is the fix.
One app. Every RGB device you own. Motherboards, keyboards, mice, LED strips, smart lights, case fans, all driven by the same engine at up to 60fps. Effects aren't hardcoded routines. They're web pages, rendered by an embedded Servo browser and sampled onto your physical LED layout every frame. And it runs on Linux, Windows, and macOS.
Your world is a canvas. Paint every pixel.

Effects render to a virtual RGBA canvas, 640×480 by default and tunable in the daemon's rendering
settings. SparkleFlinger, the render-thread compositor, latches the newest surface from each
producer at the frame boundary and blends them into one canonical frame every tick. The spatial
engine samples that frame at each LED's physical position. Effects use normalized [0.0, 1.0]
coordinates, so they stay resolution-independent across canvas sizes. Audio, screen capture, and
keyboard input feed the render every frame. One effect paints the whole room. Your keyboard,
your LED strip, your case fans, all drawing from the same source.
Hypercolor tracks 414 devices across 32 vendors in data/drivers/vendors/. 179 ship with a working driver today across 12 driver families. 233 more are researched or known, awaiting implementation or hardware to test.

New drivers land often. Full matrix: docs/content/hardware/compatibility.md. If you own hardware Hypercolor doesn't support yet, see CONTRIBUTING.md.
- Servo: an embedded browser rendering HTML Canvas, WebGL, and GLSL shaders headless at 60fps. Existing community effects work unmodified.
- Native Rust: compiled-in CPU renderers for the built-in effects, with no browser in the frame path.
Composition is GPU-accelerated separately: the SparkleFlinger compositor uses wgpu to blend producer surfaces and to import Servo frames.
Hypercolor ships 57 built-in effects (46 authored with the SDK, 11 native Rust, 10 of them in builds without the Servo renderer) spanning ambient, audio-reactive, shader, generative, and interactive styles, plus 7 display faces for devices with LCD panels. Ambient backgrounds, shader-heavy showpieces, beat-synced visualizers, and Keystrike, an interactive effect that lights up under your keystrokes. Every one is open source and built to be forked, and the catalog ships with curated cover art and tuned presets.

Map your physical desk in the UI. Drag devices onto a 2D canvas, define LED topologies (strips, matrices, rings), and the spatial sampler resolves pixels to LEDs. Pick nearest, bilinear, area average, or Gaussian sampling at every position.
FFT with beat detection, mel-band analysis, chromagram, and spectral features. Effects react to bass hits, BPM, spectral centroid, or the full 200-bin spectrum. Lock-free buffering keeps the render loop from ever blocking on audio.
Effects can react to your keyboard and mouse. The input pipeline is consent-gated and demand-driven: it is off by default, sources open devices only while an interactive effect is running, and input events ride a dedicated control-tier channel that never leaves the render pipeline. Native backends per platform: evdev on Linux, Raw Input on Windows, and a Core Graphics event tap on macOS.
- Scene engine with priority stacking, Oklab cross-fades, and automation rules
- Display faces for LCD-equipped devices: clocks, sensor dashboards, now-playing panels
- Screen capture input for ambient backlighting: Desktop Duplication on Windows (works out of the box), Wayland portal on Linux (opt-in), and Apple's system picker on macOS
- Portable device identity: devices keep their identity across cable moves, IP churn, and BIOS renumbering, and layouts can be rebound after hardware swaps
- REST API + WebSocket for full programmatic control
- MCP server for AI assistant integration (Claude Code, Cursor, and friends)
- CLI tool (
hypercolor) with table/JSON output and shell completions - Hot-reload on effect changes, no restart required
- Session and power awareness on all three platforms: logind and screensaver over D-Bus
on Linux,
WM_POWERBROADCASTplus WTS session lock/unlock on Windows, and NSWorkspace plus IOKit system-power notifications on macOS
The web UI is built right in: open http://localhost:9420 and everything is there, no
separate install. Browse effects, tweak controls live, manage devices, and design spatial
layouts from any browser. The whole thing is responsive, so your phone works as a remote
control for the rig.

Public CI ships Linux and Windows installers with every tagged release. Signed macOS artifacts use a manual release lane because they require Developer ID signing, notarization, and physical acceptance. Grab an available artifact from the GitHub releases page, or use one of the paths below.
The release installer downloads the right tarball, verifies its checksum, and sets up the systemd user service:
curl -fsSL https://raw.githubusercontent.com/hyperb1iss/hypercolor/main/scripts/install-release.sh | bashDevice-node permissions are a separate step: run just udev-install from a source
checkout, or install the .deb or AUR package, both of which ship the udev rules
themselves.
Debian and Ubuntu users can install the .deb from the releases page. Arch users have
hypercolor-bin on the AUR, and the
Homebrew formula works on Linux too: brew install hyperb1iss/tap/hypercolor.
Building from source instead:
git clone https://github.com/hyperb1iss/hypercolor.git
cd hypercolor
cargo install just
just setup
just installSetup installs the Rust toolchain, system packages, Bun, Trunk, cargo-deny, and frontend
dependencies. The installer then builds the daemon, CLI, TUI, web UI, and bundled effects,
installs a systemd user service, sets up udev rules for USB device access, and persists
i2c-dev so SMBus RGB devices survive reboot. Interactive effects also need the input
rules, which just udev-install adds (the .deb and AUR packages ship both files).
Grab Hypercolor_<version>_x64-setup.exe from the
GitHub releases page. The install is
per-machine, so expect one UAC prompt; hardware setup runs inside that same elevated pass,
including the optional PawnIO driver that unlocks
motherboard and DRAM SMBus lighting (ASUS Aura and friends). Hypercolor only offers the
PawnIO step when compatible hardware is detected. Tested on Windows 10 22H2 and
Windows 11 23H2/24H2, x64.
Current Windows builds are not code-signed, so SmartScreen will warn on first run. Choose More info, then Run anyway.
Hue, WLED, Nanoleaf, Govee, and USB-HID lighting (Razer, Corsair, Lian Li, and friends) work out of the box. So do screen-reactive effects: Windows capture uses Desktop Duplication and is enabled by default.
When a release includes an accepted macOS build, download
Hypercolor-<version>-arm64.dmg for Apple Silicon or the -x86_64.dmg build for
Intel from the
GitHub releases page. Drag
the app into /Applications and launch. Minimum macOS 15.2 (Sequoia).
Or via Homebrew Cask:
brew install --cask hyperb1iss/tap/hypercolor-appPublic CI does not publish unsigned macOS packages. macOS artifacts and the matching Homebrew updates are promoted manually only after signing, notarization, and the signed physical acceptance checkpoint pass.
Hue, WLED, Nanoleaf, Govee, and USB-HID lighting all work out of the box. Hypercolor asks for Microphone, Screen Recording, or Input Monitoring access only when you explicitly enable the matching audio, screen, or keyboard feature. Pointer-only effects do not need Input Monitoring.

¹ System-audio reactivity needs a loopback input the OS exposes: Stereo Mix or a virtual cable on Windows, BlackHole or Loopback on macOS. ² A daemon installed as a Windows service cannot see host input across the session boundary; run it in your session for interactive effects. ³ Keyboard listening needs Input Monitoring. Pointer-only effects do not. ⁴ Or per-user autostart via the desktop app.
Installed the desktop app? Just launch Hypercolor and you're done: it starts the engine, sits in your tray, and opens the UI. The terminal route works everywhere too:
# Start the engine (serves the UI at http://localhost:9420)
hypercolor-daemon
# Control from the command line
hypercolor effects list
hypercolor effects activate "Neon City"
hypercolor devices list
# Or drop into the interactive terminal dashboard (auto-starts a local daemon)
hypercolor tuiHacking on Hypercolor itself? We use just for development workflows.
just daemon # Run daemon locally
just tui # Run the TUI
just ui-dev # Leptos UI dev server on :9430
just sdk-dev # SDK dev server with HMR
just verify # fmt + lint + testjust verify covers the Rust workspace. Use the focused gates for surfaces outside
that workspace: just ui-test && just ui-build for the Leptos UI, just sdk-lint && just sdk-check && just sdk-build for the TypeScript SDK, just python-verify
for the Python client, just compat-check for device data, and just docs-build
for documentation.
Effects are TypeScript, Canvas, or pure GLSL. The SDK compiles them to self-contained HTML files that the engine renders at 60fps. Audio data, control values, and canvas context are all injected automatically.
import { effect } from "hypercolor";
import shader from "./fragment.glsl";
export default effect(
"Borealis",
shader,
{
speed: [1, 10, 5], // → slider
intensity: [0, 100, 82], // → slider
palette: ["Northern Lights", "SilkCircuit", "Cyberpunk"], // → dropdown
},
{
description: "Aurora borealis, layered curtains of light",
},
);Four tiers, pick the one that fits: GLSL (single file, zero JS), effect() (one-liner
shader binding), canvas() (Canvas 2D draw functions), and full OOP (class-based with
lifecycle hooks).

Solid arrows are Cargo dependencies, pointing from the dependency to the crate that
consumes it; dashed arrows are runtime relationships, not build edges. hypercolor-color
and hypercolor-types reach nearly every crate in the workspace, so only the structural
edges are drawn here. The full graph is in AGENTS.md.
It's Rust all the way down. The daemon, CLI, TUI, unified app, and HAL drivers are all Rust. The web UI is Rust compiled to WASM via Leptos. Even the embedded browser is Servo (Rust). The only non-Rust code is the TypeScript effect SDK and the GLSL shaders it compiles.
The render thread runs on a dedicated OS thread with adaptive FPS (10 to 60, auto-shifting
across 5 tiers based on measured budget). Each tick, SparkleFlinger composes frame producers
into one canonical surface, with a zero-copy bypass fast path when a single full-opacity
layer is active. The event bus uses lock-free tokio::sync::watch channels for high-frequency
frame data and broadcast for discrete events. zerocopy structs handle wire-format encoding
at zero allocation cost per frame. The spatial engine caches LED positions and samples the
composed frame with configurable interpolation (nearest, bilinear, area average, Gaussian).
Workspace lints forbid unsafe in application, driver, and domain crates. The explicit
exceptions are the audited platform crates (GPU surface import on all three platforms,
screen capture via PipeWire, ScreenCaptureKit, and Desktop Duplication, host input on
macOS and Windows, session and power monitors on all three platforms, macOS now-playing
media, the PawnIO SMBus broker, the signed Windows helper, and platform filesystem glue)
plus the desktop app shell; each opts out explicitly and denies undocumented unsafe
blocks. Edition 2024. Rust 1.94+.
Hypercolor is in active development. The core engine, effect SDK, web UI, TUI, and 12 shipping driver families work today on Linux, Windows, and macOS. Public release automation ships Linux and Windows installers; signed macOS artifacts use the manual acceptance lane described above. Every screenshot in this README was captured from a live instance running on real hardware.
Worth knowing before you install:
- SMBus (motherboard/DRAM RGB) is Linux and Windows only. The "What works where" table above has the full picture.
- Session and power integration covers sleep/resume on all three platforms, plus screen lock/unlock on Linux and Windows and session active/inactive on macOS. Idle-based dimming is implemented in the policy layer but no platform monitor reports idle transitions yet.
- Windows binaries are not yet code-signed, so expect a SmartScreen warning on first launch. Published macOS artifacts are signed and notarized after manual acceptance.
- The
hypercolorSDK andcreate-hypercolorscaffolder are on npm; scaffold an effect workspace withbun create hypercolor. The Python client is on PyPI ashypercolor.
Coming soon: effect marketplace, Wasmtime plugin system for community backends, Wooting analog keyboards, and driver families for Cooler Master, NZXT, and Logitech. See the full compatibility matrix for researched hardware waiting on implementation.
Please report vulnerabilities through the process in SECURITY.md. Community
participation follows the CODE_OF_CONDUCT.md.
Hypercolor grows on contributions. Drivers, effects, UI polish, docs, all of it lands here.
Writing effects is the fastest way in. The SDK compiles TypeScript, Canvas, or GLSL straight to HTML, and the engine picks them up on save. Device drivers are where the leverage is highest. If you own hardware that isn't on the supported list, you're the person to add it.
