Design tool, minus the ceremony
Wireframes at the speed of the idea
Sketch a screen, wire the clicks, send a link. NinjaMock keeps the fidelity low on purpose, so the conversation stays about the product instead of the drop shadows.

Everything the idea needs. Nothing it doesn't.
Four things NinjaMock does properly, instead of forty it does halfway.
Sketch-style by design
Hand-drawn styling tells everyone in the room this is a draft. People critique the flow instead of arguing about the shade of blue, and you get better feedback three weeks earlier.

Prototypes that actually click
Link screens, add states and transitions, and hand over a URL. Stakeholders test the flow on their own phone — no walkthrough meeting required.

Collaboration without merge conflicts
Multiple cursors on one canvas, live. Comments land on the element they are about, not in a separate thread nobody reads.

Reusable component libraries
Build your own controls once and reuse them across every project. Change the master, and every screen that used it updates.

Built for the people who have to decide something
- Product managers
- Turn a paragraph of requirements into something the team can react to.
- Developers
- Agree on the screen before you write the component.
- Designers
- Explore twenty layouts in the time a high-fidelity mockup takes to render one.
- Teachers and students
- Teach interface design without a licence per seat.
