The Whiteboard for
Modern Engineering
A high-performance, distraction-free canvas for flow diagrams, technical brainstorming, and visual problem solving. No fluff, just logic.
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.
Custom Canvas Engine
A fully custom-built canvas engine where rendering, mouse input, and keyboard interactions are handled in-house for precise control over every shape.
Real-Time Sync & Batching
Canvas edits are captured instantly and batched efficiently before syncing over the network, keeping collaboration smooth and responsive.
Structured Shape Model
Each shape is implemented as an independent entity with its own properties, enabling predictable updates, transforms, and collaboration behavior.
Multi-User Collaboration
Multiple users can work on the same canvas simultaneously, with all interactions reflected live across sessions without manual refresh.
Feedback from early users
"Finally, a whiteboard that feels built for developers. No distractions, just the tools I need to think clearly."

Roadmap
We are building in public. Here is what is coming next.
Real-Time Multi-Room Collaboration
Create multiple rooms and collaborate with multiple users in real time, with all canvas changes synced instantly.
Collaboration Conflict Handling
Improved handling for simultaneous edits, deletions, and shape updates to ensure consistent behavior during concurrent actions.
Advanced Collaboration Controls
Smarter editing rules, ownership models, and collaboration refinements to make real-time teamwork more predictable.
