Slack apps paint with a palette of blocks and conversations. Create a masterpiece by reading our tips for app design and conversational flourish.
Slack apps communicate with the world through one of a few potential surfaces.
These surfaces are composed using a collection of puzzle pieces called Block Kit. Because these visual components are designed by Slack, they have a consistent look and feel across every client, and for every user.
No need to worry about creating pixel-perfect CSS, or accessible, cross platform app designs. We'll take care of all that for you.
Instead you can focus on composing a symphonic set of surfaces for your app to connect with users.
We previously recommended storyboarding your app to grasp the twists and turns that happen when interacting with users.
Refine this sketched-out sequence by digging into the composition of your app's surfaces. It's time to think about the layout and components of each space, and how users flow between steps using interactivity.
