What you can build

Character portraits

NPCs, protagonists, enemies, party members. Full body, headshots, action poses.

Environment concept art

Levels, biomes, vistas, lighting studies. Ideation before you commit a single voxel.

UI & HUD mockups

Inventory icons, menu backgrounds, button states, achievement badges.

Item icons

Weapons, armor, potions, collectibles. Consistent style across hundreds of items.

Marketing key art

Steam capsule, hero banners, social media promo, press release imagery.

Store page screenshots

Composite screenshots for store listings, with consistent lighting and tone.

Pre-rendered cinematics

Short cinematic clips for trailers, intros, and ending sequences using image-to-video.

Reference for animators

Pose references, lighting references, style references for hand-drawn or 3D animation work.

The catch

There isn't one. Full commercial use on the free tier. No watermark on any tier including free. 200 credits at signup plus 100 credits every day — that's enough for ~100 images per day, every day, forever, free. No subscription required to ship a full game's worth of concept art.

If you need more — say you're in a sprint and need to generate 500 assets in a day — Supporter tier is $9/month and removes the queue during peak hours. Pro tier is $19/month with 3,000 credits. That's it. No "indie game studio" tier with a 5-figure starting price.

Why I made this for game devs

I'm bootstrapped. I know what indie budgets look like. I know what it feels like to want to ship a game and choose between paying for art and paying for rent. I built ZSky because I was tired of seeing indie devs paywalled out of basic tools that VC-funded studios got for free. ZSky stays free for indies because that's what I'd want.

If your game ships and you remember where the art came from, leave a "made with ZSky" line in your credits. Or don't. Either way I'm rooting for you.

What devs ask

Can I use ZSky outputs in a commercial game?

Yes, on every plan including the free tier. Ship character portraits, environments, UI assets, marketing key art, store page screenshots. No watermark, no licensing fee, no royalties.

Do I need to credit ZSky in my game?

No obligation. Credit is appreciated but never required.

What about Steam, itch.io, and console store policies?

Steam allows AI-generated content as long as you disclose it on the store page. itch.io is permissive. Console publishers vary — check Sony, Microsoft, Nintendo policies. ZSky outputs do not contain hidden watermarks or metadata that would identify them as AI-generated.

How many assets on the free tier?

200 credits at signup + 100 daily (max 300 at any time). 1 credit per image = ~100 images per day, every day, forever.

Is there a game jam offer?

Yes. Email [email protected] with the jam name and dates. We bump you to Pro for 30 days, no questions asked.

Can ZSky generate consistent characters across multiple poses?

Yes, via image-to-image. Upload your initial render as a reference, then prompt new poses. Not perfect but significantly better than starting from scratch. 2 credits per generation.
