Unlock your productivity potential with Slack Platform

Connect, simplify, and automate work.

Save time with Slack's new modular automation tools

With our new modular foundation, automation is grounded in building blocks. They're remixable, reusable, and hook into everything flowing in and out of Slack.


Create modular functions that automate work in Slack and connect with your services.

Share your functions so anyone can add them to their own workflows.


Workflows let you create complex and adaptable automations by building chains of functions.

Use your custom functions, pick from pre-defined Slack functions, or combine both to get the workflows you want.


Add triggers to customize how and when to kick off a workflow.

React to events in Slack, run on a schedule, or trigger from external services using webhooks.

Deploy ideas faster

Our developer tools simplify the most tedious parts of development and ensure your automations are enterprise-grade from day one.

Slack CLI

Fast track development by creating, scaffolding, and deploying functions and apps from the command line.

Managed infrastructure

Deploy your automations to secure and managed Slack infrastructure, so you can focus on building.


Streamline all your standard database operations by storing, querying and deleting data on Slack infrastructure.

App manifests

Save time when creating and configuring apps by using shareable and reusable manifest files.


Resolve issues faster by using function-level and app-level logging to debug.

Your work just works, on any device

Block Kit lets you build interfaces without a UI designer. It's available for use in surfaces across all devices without any extra code.
