Build with your crew.
Build with your crew.
Or with the whole crowd.
Every app on EngineZero is either Private or Public. Pick the energy.
Private
🔒
Your crew, behind closed doors
Invite-only. Bring the squad, build the app, keep it under wraps. Perfect for stealth startups, client work, and ideas not ready for the spotlight.
- ✓ Invite-only access
- ✓ NDA-friendly by default
- ✓ Team comments & change proposals
- ✓ Versioned, exportable specs
Public
🌐
The crowd, in your corner
Anyone can find your app, upvote it, comment, and propose changes. Like Reddit, but instead of memes you get real app ideas with screens you can click.
- ✓ Open to the internet
- ✓ Upvotes & downvotes surface the good stuff
- ✓ Anyone can propose changes
- ✓ Comment threads on every screen
The studio
Design, debate,
Design, debate,
and ship — all in one window.
Every app gets its own live design board. Screens, status, comments, votes, and proposed changes — sitting next to each other instead of scattered across six apps.
Live screen board
See what's shipped, cooking, or still on the napkin.
Inline change proposals
Roast a screen, suggest a patch, get it merged.
Design DNA, baked in
Color palette, typography, components — all versioned.
AI co-pilot
Turn "like X but for Y" into actual screens and specs.
Design DNA
Public feed
The good ideas float to the top.
Public apps get upvoted (or downvoted) by everyone. The best ones get traction, contributors, and eyeballs.
