What Slack Code means for you

Slack has launched a feature called Slack Code that turns AI coding work into something a whole team can watch and steer together, rather than something one developer does alone in a terminal (the text-only command window coders normally use to run AI coding tools).

Salesforce-owned Slack announced Slack Code on 20 August 2026. The idea is simple: tag an AI coding agent in any Slack conversation, and it opens a dedicated "code channel" for that task.

Inside the channel, tabs show the ongoing conversation, the agent's plan, the code changes (called diffs) it has made, and live previews of any HTML output. Team members can see exactly what the agent is doing, leave feedback that the agent then acts on, and give final approval before the work ships.

Once a task is finished, the channel archives itself automatically, keeping the full history as a record of what was built and approved.

Four AI coding tools are launch partners: Anthropic's Claude Code, Cognition's Devin, GitHub Copilot and Vercel's agent. OpenAI is building its own integration. Slack also plans to open up the code-channel technology so other developers can build on it later.

GitHub's chief product officer, Mario Rodriguez, said: "Slack is a strategic part of a broader GitHub promise: humans set direction, agents close the loop."

If you use Slack at work, Slack Code is included in every plan, so there's no extra charge for the feature itself. However, the AI agents you tag may require their own paid account with the company that makes them, such as Anthropic or GitHub.

The bigger shift is who gets to watch AI coding happen. Previously, one developer working with an agent in a terminal was the only person who saw the process. Now, anyone in a code channel, including non-coders such as product managers or designers, can follow the plan, comment, and sign off on the result before it goes live.

Slack said the feature is rolling out gradually, so it may not appear in your workspace immediately.

Once Slack Code reaches your workspace, you can try it by tagging a supported coding agent, such as Claude Code or GitHub Copilot, in any Slack conversation. This automatically creates a code channel where you and your team can track the work and approve it before it ships. More detail is in Slack's own coverage of the launch and in VentureBeat's report on the feature.
