Slack Launches Slack Code to Let AI Agents Spin Up Project Coding Channels

The tool moves developer work into Slack by letting teams write, preview, track, and archive code with partner AI agents in dedicated channels.

Overview

  • Slack launched Slack Code on Thursday, August 20, 2026, a feature that creates project-specific code channels when a user tags a coding agent.
  • Tagged agents such as Anthropic’s Claude, Cognition’s Devin, GitHub Copilot, and Vercel Agent will spin up channels that include user tabs for contributors, side-by-side diff comparisons, and live HTML previews.
  • Channels automatically archive when work is complete and keep an audit log to record changes and decisions, and Slack says high-risk actions like merges require human sign-off under its enterprise controls.
  • Slack Code is available on all Slack plans and integrates with agents from the Slack Marketplace so teams can pick different vendors inside the same workflow.
  • The feature formalizes earlier experiments from Slack, building on a December 2025 research preview and a June 2026 persistent-agent beta, and it signals Slack’s push to expand beyond messaging into developer workflows that could affect Salesforce’s platform strategy.
