Focus on what matters

Existing solutions for remote system designs are painful to use because they are not designed for it. Oasys aims to solve all these problems so you can focus on what matters. Save time by having coordinate and orchestrate remote system designs for you.

Diagram and Whiteboard Mode

Distraction-free diagram mode and whiteboard brainstorming mode let users focus on designing while keeping the context around.

Utilities

Doing elementary math and text formatting on a virtual whiteboard is not the focus of a system design, so we provided these out of the box.

Recorded Sessions

Content of the diagram, whiteboard, and utilities are automatically recorded and can be reviewed at any time. See how a system evolves over time with changing requirements and all the decisions that led up to a certain design.
