Overview
- Slack launched Slack Code on August 20, 2026 and made the feature available at no extra cost on every Slack plan, including free workspaces.
- Supported partner agents such as Anthropic’s Claude, Cognition’s Devin, GitHub Copilot and Vercel can be tagged to automatically spin up a project-specific code channel that holds the agent’s plan, repo and branch, code diffs and a live HTML preview.
- Only agents can create code channels for now, and Slack built a channel API that is restricted to launch partners with plans to open it more broadly later.
- Each code channel archives itself when work finishes and remains searchable as an audit log, and Slack enforces inherited permissions plus mandatory human sign-off before high-stakes actions like merging to production.
- Slack positions Code as a move from solo AI helpers to multiplayer, agent-driven development inside workspaces, a step that could speed iteration but also raise governance, security and technical‑debt challenges as teams adopt the workflow.
