Meet Slack Code.

Work happens in the open by default, so context and knowledge carry from person to person, and from person to agent. AI development becomes a multiplayer activity. Code channels are designed to scale for agents' work in ways that threads and public channels just can't, because they're built for output. What shows up isn't just messages — it's working code, prototypes, and documents, built right in Slack.

With Slack Code, when you have an idea or need to build a new feature, update a web page, or fix a bug, you tag in a coding agent, like Claude Tag or ChatGPT, and it spins up a code channel to tackle the task. Everyone in the channel can see the conversation, review code diffs, check live previews, give feedback, and approve the work before it ships. No specialized tools, no leaving Slack.

Slack Code brings AI development directly into Slack, changing how we build and work. Code channels are the first space in Slack that's built specifically for people to collaborate with agents on software development, together. They're inherently multiplayer and accessible to everyone. And, they bring developers, PMs, designers, non-technical teammates into the same shared workspace as the agent, so building software — from idea to shipped product — isn't just for engineers anymore. No other platform offers the same combination of an open ecosystem and a multiplayer coding environment for humans and agents to work together at once.
