Free VJ Software for Mac (2026)
RenderWave has a real Free Edition: the full shader library (85 shaders, 27 effects) at 720p, no watermark, no card. Audio reactivity, MIDI, and Ableton Link are all in. It runs on Apple Silicon Macs with macOS 15 or later, and it never expires. Below, the honest comparison against every free and demo option worth installing on a Mac.
What "free" actually means here
"Free VJ software" means four different things, and the differences matter for your show:
- Feature-limited free tier: runs forever, gates pro features. RenderWave's Free Edition works this way: the full shader library at 720p, with Syphon output, custom overlays, and 8K reserved for Studio.
- Unlimited demo, no commercial use: fully functional but the EULA forbids paid gigs. VDMX 6 Demo and TouchDesigner Non-Commercial.
- Genuinely open source, free forever: Check each source and bundled-asset license before commercial use. Radiance, Ghost Arcade, OBS Studio.
- Browser-based or livecoding: free, no install. Hydra.

RenderWave Free Edition
The free-forever tier of the Mac-native Metal shader instrument. You get the full shader library (85 production shaders), 27 composable post-processing effects, per-parameter audio reactivity, MIDI Learn, and Ableton Link, rendering clean 720p output with no watermark. It's built for VJs learning the craft, practicing sets, and playing small rooms where 720p holds up.
What you get
- Native Swift + Metal 3 on Apple Silicon
- Full shader library, no watermark, never expires
- Per-band audio modulation (bass, mid, mid-high, high)
- MIDI CC mapping + Ableton Link included
- App updates included
What's gated
- Output caps at 720p (Studio goes to 8K via MetalFX)
- No Syphon output or custom overlays
- One Mac (Studio covers two)
- Needs an account and a short survey, not a card
- Apple Silicon only, macOS 15+ (no Intel, no Windows)
Free Edition: full shader library at 720p, no watermark, no card. Paid Studio: 14-day full-access trial on monthly (card required), cancel before day 15, no charge; $9.99/mo, $99/yr, or $299 perpetual. 30-day money-back guarantee on charges. See pricing.
Get the Free EditionThe other free options, honestly
VDMX 6 Demo: the generous demo
Fully functional, no watermark, no time limit, but the EULA prohibits commercial use and project-saving is disabled. The license is $199.99 perpetual. Best for learning the most respected Mac VJ tool deeply before paying. Compare VDMX vs RenderWave →
Ghost Arcade, the open-source VJ + mapping suite
AGPL-3.0, free forever including commercial use. Every feature unlocked: dual-deck VJ, X-fader, Spout/Syphon, AI gen (BYOK), 180+ effects. Cross-platform, not Apple-Silicon-optimized the way a native Metal app is. Compare Ghost Arcade vs RenderWave →
Radiance, if you want modern Rust + WGSL open source
Radiance documents a Rust rewrite, WGSL effects, and beat detection. Its license file, checked October 24, 2026, uses MIT for source by default and separate terms for some files, including noncommercial data/model assets. Check those terms and the current Mac build before using it in a paid show.
And OBS Studio + Syphon for free routing and recording
GPL-2.0, genuinely free forever. Not a VJ instrument; it's broadcast/recording plumbing. Pair it with a source tool (RenderWave, VDMX, Radiance) via the Syphon plugin to record or restream your show in ProRes or H.264 for free.
When to upgrade from free
Free is for learning, practicing, and building your rig. It starts to bite when:
- You need more than 720p for an LED wall or projection rig (Studio goes to 8K via MetalFX).
- You need Syphon output or custom overlays (both are Studio features).
- You perform from two Macs (the Free Edition covers one, Studio covers two).
- You realize the tool is genuinely useful. Pay people who make software you use.
RenderWave Studio is $9.99/mo, $99/yr, or $299 perpetual (12 months of updates). Monthly starts with a 14-day full-access trial, card required; cancel before day 15 and you won't be charged. 30-day money-back guarantee on charges.
Free VJ software FAQ
- Is there free VJ software for Mac?
- Yes. RenderWave's Free Edition is free forever on Apple Silicon Macs: the full shader library at 720p with no watermark and no card. Other strong free options in 2026 are the VDMX 6 Demo (fully functional except project saving) and two open-source apps, Ghost Arcade (AGPL-3.0) and Radiance (MIT source, with asset-specific exceptions). RenderWave is the only one built natively on Metal 3 for Apple Silicon with per-parameter audio reactivity.
- Is VDMX free?
- VDMX 6 has a fully functional free demo with no watermark and no time limit, but the demo prohibits commercial use: paid gigs require the $199.99 perpetual license. Project-saving is disabled in the demo. For learning, the demo is effectively the full product; for performing at paid shows, you need the license.
- Is Ghost Arcade free?
- Yes. Ghost Arcade is fully free and open source under AGPL-3.0, including commercial use under the AGPL terms. Every feature is unlocked: dual-deck VJ, X-fader, macros, Spout/Syphon, AI generation (bring your own API keys), and 180+ effects. No paid tier, no watermark, no expiry.
- What is the best free VJ software for Mac?
- It depends what you mean by free. For a Mac-native Metal instrument that stays free, the RenderWave Free Edition: the full shader library at 720p, no watermark, audio reactivity and MIDI included. For a fully free forever open-source tool, Radiance or Ghost Arcade. For learning the most respected Mac VJ tool before paying, the VDMX 6 Demo.
- Does the RenderWave Free Edition have a watermark?
- No. The Free Edition renders clean output at up to 720p with no watermark. It requires an account and a short survey, not a card, and it never expires. Paid Studio plans ($9.99/mo, $99/yr, or $299 perpetual) add 8K output via MetalFX, Syphon output, and custom overlays; monthly starts with a 14-day full-access trial, card required, cancel before day 15 with no charge.
- What's the catch with free VJ software?
- Free tiers always gate something. RenderWave's Free Edition caps output at 720p and leaves out Syphon output and custom overlays; it also asks for an account and a short survey. The VDMX demo disables project saving. Open-source tools are free forever, but Ghost Arcade carries AGPL obligations if you modify and redistribute (Radiance uses MIT by default for source, with asset-specific exceptions), and support is community-grade rather than vendor-grade.
Start free, upgrade when the room gets bigger
The Free Edition gives you the full shader library at 720p with no watermark and no card. When you need 8K, Syphon, or overlays, Studio is one click away.
