The Problem

General-purpose tools fail at scale.

Most whiteboarding tools are built for casual brainstorming. They choke on large diagrams, lack precise controls for complex systems, and prioritize stickers over structure. Developers need tools that respect technical constraints and performance.

The Solution

Precision tooling for complex systems.

  • speed

    High-Performance Canvas

    Built for smooth interactions and real-time updates, even as diagrams grow in complexity.

  • api

    Structured Canvas Data

    Every element on the canvas is modeled clearly, enabling precise editing and consistent collaboration.

  • contrast

    Cognitive Clarity

    High contrast, clean themes designed to reduce eye strain and keep focus on your diagrams.

Core capabilities.

Built on technical primitives that matter to engineers.

Structured Shape Model

Each shape is implemented as an independent entity with its own properties, enabling predictable updates, transforms, and collaboration behavior.

Roadmap

We are building in public. Here is what is coming next.

Now

Real-Time Multi-Room Collaboration

Create multiple rooms and collaborate with multiple users in real time, with all canvas changes synced instantly.

Next

Collaboration Conflict Handling

Improved handling for simultaneous edits, deletions, and shape updates to ensure consistent behavior during concurrent actions.

Later

Advanced Collaboration Controls

Smarter editing rules, ownership models, and collaboration refinements to make real-time teamwork more predictable.
