Questions, answered.
Do I need to know Metal?
No. MetalForge writes the Metal Shading Language for you. You pick an effect, tweak sliders, and copy the .metal file into your Xcode project. Reading MSL helps if you want to tweak further, but it isn't required.
Where can I use these shaders?
Anywhere SwiftUI runs — iOS 17+, iPadOS 17+, macOS 14+, visionOS 1+, tvOS 17+, watchOS 10+. Every export uses SwiftUI's [[stitchable]] signature applied via .colorEffect, .distortionEffect, or .layerEffect.
Can I use them commercially?
Yes. You own what you export, on every plan. Ship it in paid apps, indie projects, or client work.
Is the preview really running my shader?
The preview runs an equivalent WGSL version of the shader in your browser via WebGPU — same math, different language. The .metal file you download is hand-written MSL with the same algorithm. Browsers can't run Metal directly, so we maintain both.
What's the difference between Free and Pro?
Free gives you every tool and every parameter, at full quality, for as long as you like — the editor, Lumen, Pixel, Loaders and Characters. Pro is the part you take away: the .metal file and the SwiftUI view, the React Native, Android and web versions of the same look, the runnable Xcode and Expo projects, and in Lumen the finished picture — PNG, JPEG, a layered .psd, a layer pack or a clip.
How many things can I download on Pro?
As many as you like. There is no per-export fee, no monthly cap and no watermark — one payment covers every tool on the site, every effect in it, and every look you make with them, and it does not expire.
Is this a subscription?
No. Pro is a single €49 payment and it is yours to keep — there is nothing to cancel and nothing to renew. New effects and tools we add afterwards are included.
I already pay €5 a month. What happens to me?
Nothing changes unless you want it to. Your monthly plan carries on exactly as before, and you can still cancel it in one click from your account page. If you would rather stop paying monthly, buy the €49 lifetime from that same page and we cancel the monthly for you at the end of the period you have already paid for.
