Slack Developer Hub (slack.dev)
Build on the platform that agents and AI call home.
Slack Developer Hub is a developer resource for building apps, agents, and AI-powered tools for Slack. It brings together documentation, development tools, code samples, and learning materials, along with a path for publishing apps to the Slack Marketplace.
The toolbox includes Slack CLI for managing an app's lifecycle from development to deployment, ready-to-use building blocks for creating agents, an MCP & Skills Plugin for powering agents with Slack context and skills, Bolt frameworks and SDKs, a developer sandbox, code samples, and Block Kit Builder for prototyping message layouts. The Marketplace section provides publishing guidance, submission checklists, scope references, and app guidelines. Learning resources cover tutorials, workshops, and learning paths.
The hub is aimed at developers building for Slack, from those starting a first app to teams distributing apps through the Marketplace. The pages do not state specific pricing, plans, or packaging details for these resources.
