Collaborate freely and openly with markdown and applications


What's Cattaz!

Brings all of the activities of the team together at one place.
Changes team's "Working Style", "Communication", "Motivation".
It is an evolved Wiki that can launch, organize, accumulate and share knowledge freely using applications tailored to the activities of teams from Markdown.

Cattaz Concept


Edit Markdown

CommonMark, standardization of Markdown, can be used for desrciption.
With Markdown, keep the text in an easily formatted state.
Copy & paste text as it is without requiring conversion between Cattaz and other Markdown editors.
As you edit the text, you can see the preview in real time.
Try it on the Sandbox page.


Run Applications

Launch the application on the preview screen by specifying the application name in fenced code block (block starting with 3 backticks).
Markdown makes it easy to enter complex information from the application's UI.
Also, depending on the UI of the application, display the information in user friendly form.
Placing multiple applications on one page, information entered in the application can be immediately reflected in the editor and can be saved as one page.
Keeping everything on a single page in Cattaz, teams can co-create activities smoothly.

APP Work

Easily Develop Applications

Engineers can develop and implement applications that run on the preview screen in the same way as creating web applications.
Write the application using JavaScript and React library.
By processing the specified props, you can realize an application with synchronization function added.
Check the developer's guide for Hello world application to start developing your own application.

APP Development

Real-time Simultaneous Editing

Markdown texts and applications can be collaboratively edited simultaneously by multiple people in real time, so you can efficiently share and co-create information. Cattaz is a also powerful tool when collaborating with people who are at remote locations such as remote conferences.

Real-time Cllaboration

Use Case



It can be used to create minutes of meetings.
It facilitates communication at the remote conference.
It will help telework and promote reform of working style.


Agile Development

By using Kanban application, KPT application, etc., summarize sprint's plan and review into one page.
It visualizes the activities of the team and helps speed up agile development.



Events such as ideathon and hackathon can be operated with Cattaz, and knowledge born can be stored as it is on a Cattaz page.
Through collaborative editing, we can co-create while enjoying, helping to create valuable things.


At first, we thought how a platform would be for the engineers to be lively and freely and openly active. With advent of many tools, various working styles, the way to master these tools and how to share information is becoming complicated. Although freedom is increased, but it is getting more confusing. So, we have developed "Cattaz" to share everything at one place and to maximize the capabilities of engineers and enable them to have fun activities. In addition, we aim to make Cattaz a free and vigorous place for people of various occupations, with diverse cultures, not just limited to engineers. "Cattaz" has been released as OSS (open source software).
If you are interested, let's create a free and vigorous place together.
