Slack Code

Slack Code is Slack’s collaborative coding environment that brings people and AI coding agents into a shared space to build software together. Instead of keeping agent-driven development in a private terminal, IDE, or browser tab, teams can use dedicated code channels to plan work, prompt an agent, review output, and keep the conversation around the work in Slack. Code channels are temporary spaces created for a specific project or task, giving teams a focused place to collaborate without cluttering their main channels. In a code channel, teammates can mention a supported AI agent, describe what they want built or fixed, share files and context, and follow the agent as it works. Agents can produce code, create or update files, generate canvases, and provide HTML previews or other artifacts depending on the integration. Teams can inspect code diffs, comment on changes, make suggestions, and approve or redirect AI-generated work. Status indicators also help teammates see whether an agent is working, idle, blocked, or finished, while quick actions can connect the work to related development workflows. Slack Code is differentiated by making AI-assisted software development a multiplayer workflow rather than a solo coding session. The code channel keeps the project conversation, agent activity, artifacts, and human feedback together, while Slack’s existing visibility, permissions, and security model applies to the workspace. Supported agents currently include Claude, Devin, GitHub Copilot, and Vercel, with availability depending on the workspace and installed integrations. Completed code channels can be closed or archived while their messages and artifacts remain available for search and future context. For founders, engineering teams, and other collaborators, Slack Code is useful when software work benefits from shared direction, review, and rapid feedback instead of a single developer working with an agent in isolation. It can support feature development, bug fixes, prototypes, code review, and other contained projects where multiple people need visibility into the agent’s work. Slack Code is currently rolling out gradually, and access depends on having a supported agent installed; teams should also verify the specific agent’s capabilities and account requirements before adopting it.
