Ghost Arcade vs RenderWave: Curated vs Cataloged
Ghost Arcade ships 316+ open-source shaders with mixed quality. RenderWave ships 85 production-grade Metal-compute shaders curated for the club floor, with perpetual pricing and Mac-native performance.
Quick Verdict
Ghost Arcade is a genuinely good open-source project. Fully free under AGPL-3.0 with every feature unlocked, cross-platform, ~316 GPU shaders, 8-band FFT audio with onset detection, dual-deck VJ, Spout/Syphon, and a mobile companion. If you want a no-cost VJ rig that runs on a Linux laptop, it's the strongest option in the category.
RenderWave is a different bet. 85 hand-tuned Metal-compute shaders instead of 316 community-contributed ones. Mac-only, Apple Silicon native, no AGPL strings, no Electron, no ISF interpreter overhead; every shader is a compiled Metal Shading Language compute kernel. Quality over quantity, by design.

Curated vs Cataloged
The 316-vs-85 number is real. So is the philosophy gap behind it.
RenderWave: curated
Every one of RenderWave's 85 shaders is a compiled Metal compute kernel: hand-tuned, parameter-mapped, audio-band wired, thermal-tested on M-series at 4K and 8K MetalFX.
The bar to ship a new shader is performance under sustained 4 AM load, not novelty. If it can't hold 60 fps with bass mod at 100% on an M2 Air, it doesn't ship.
You spend zero time auditioning shaders to find one that works. You spend all your time performing.
Ghost Arcade: cataloged
316+ shaders is a real flex if your workflow is browse-and-discover. Open-source contribution means the library grows on its own and tracks every micro-trend in the shader community.
The trade-off: variable quality. Some shaders are gorgeous. Some are toy projects. Some break under heavy audio modulation or eat GPU at 1080p. You have to audition.
Great for explorers and patch-builders. Higher friction for a Friday-night gig where the only acceptable outcome is "it works."
Where Ghost Arcade Wins
Credit where it's due. These are real advantages, and we'd be lying to call them anything else.
Free + open source
Fully free under AGPL-3.0 with every feature unlocked. No paid tier. If your budget is zero, this is unbeatable. RenderWave has a free tier (720p, no watermark) but it's a marketing free, not a developer-philosophy free.
Cross-platform
If you VJ on Linux or Windows, RenderWave isn't an option. Ghost Arcade runs everywhere, and that matters for festival rigs, backup PCs, and rooms where Macs aren't standard.
Shader volume
316+ shaders is 3.7x RenderWave's 85. If you're a shader explorer, archivist, or you want to play "find the obscure thing nobody's used at a club," Ghost Arcade has the library for it.
8-band FFT + onset detection
Ghost Arcade's 8-band FFT with kick/snare onset events is a strong implementation. For percussion-heavy tracks where you want hits to map directly to visual events, it's a clean primitive.
Mobile companion
The iPad / phone companion app is a legit feature for run-and-gun VJing. RenderWave currently leans on MIDI controllers and Ableton Link; a true mobile control surface is on our roadmap.
AI generation included
Ghost Arcade ships AI generation tools (bring your own Claude / Luma keys) as part of the free build. RenderWave's roadmap takes a more conservative line. We ship AI features only when they hold under sustained live load, not as a marketing checkbox.
Where RenderWave Wins
The cases where Mac-native, Metal-compute, and a tight commercial license matter more than shader count.
Mac-native Metal-compute
RenderWave shaders are compiled Metal compute kernels. Ghost Arcade's cross-platform engine uses an ISF-style interpreted shader runtime for portability. Different performance ceilings on M-series.
Curation quality
Every RenderWave shader passes the same gauntlet before shipping: parameter sanity, audio-band wiring, thermal hold at 4K, 8K MetalFX upscale clean. No "this one looks cool but it tanks the framerate" surprises mid-set.
Perpetual, no AGPL
$299 perpetual with a clean commercial license. No source-disclosure obligations if you build custom workflows or ship visuals for client work. Buy once, own forever, no legal asterisks.
3D shader pipeline
RenderWave's 3D shader pipeline (perpetual tier) gives you depth-aware effects and 3D scene composition that ISF runtimes structurally can't match. If your show calls for camera moves, particle volumes, or projection-mapped 3D, this is the divergence point.
Support SLA
Direct vendor support on paid tiers: email response within one business day, Discord for community help. Open-source projects rely on volunteer community time, which is great until your gig is in 4 hours.
Won't crash at 4 AM
RenderWave's whole reason to exist is that it has to hold for a six-hour set. We test the curated 85 under continuous load. Every release goes through real-club thermal soak before it ships.

Frequently Asked Questions
Is Ghost Arcade free?
Yes. Ghost Arcade is fully free and open source under AGPL-3.0. Every feature is unlocked: dual-deck VJ, X-fader, macros, snapshots, AI generation (bring your own API keys), Spout/Syphon output, recording, and more. No paid tier, no watermark, no expiry.
How many shaders does Ghost Arcade have?
Ghost Arcade ships 316+ GPU shaders, sourced and contributed community-wide. The library is wide and ranges in quality from polished to experimental, characteristic of any open-source shader catalog.
How many shaders does RenderWave have?
RenderWave ships 85 production-grade Metal-compute shaders, curated specifically for club and live-performance use. Every shader is parameter-tuned, tested for thermals on M-series Macs, and audio-band wired before it ships. Quality over quantity is the explicit design choice.
Does Ghost Arcade run on Mac?
Yes. Ghost Arcade is cross-platform and runs on macOS, Windows, and Linux. RenderWave is Mac-only by design, built natively on Swift and Metal 3 for Apple Silicon with no cross-platform rendering layer.
Is AGPL a problem for commercial VJ work?
The AGPL-3.0 license has source-disclosure requirements that activate when you modify and distribute (or network-serve) the software. For most touring VJs who only use the app, it's a non-issue. But if you fork Ghost Arcade, add proprietary shaders, and ship that fork to a client, you may be required to release your changes under AGPL. RenderWave's commercial license has no such requirement: subscription and perpetual licenses are no-strings.
Which has better audio reactivity?
Both offer multi-band FFT audio analysis. Ghost Arcade ships 8-band FFT with kick/snare onset event detection, strong for percussive tracks. RenderWave's per-band modulation (bass / mid / mid-high / high, plus per-band transient hits) is configurable per shader parameter, which gives finer-grained control over which visual element reacts to which frequency band. Different design philosophies, both legitimate.
